American Audio Amplifier V3001 Plus Manual V01 Series

							
OUTPUTS: 
Binding  Post/Banana  Plug  -  Connect  your  speakers  to  the  binding  post  outputs  on  the  rear  of  the  amplifier.  The  speaker  wire  may 
be  connect  by  bare  wire  (directly  connected,  usually  for  permanent  connections),  banana  plug,  or  spade  connec
-
tor. Connections are made to Channels 1 and 2 output’s for stereo mode or across the red terminals of Channels 1 
and 2 for Mono Bridge Mode. 
Important Notice: Although a speaker will operate with the positive and negative leads plugged into either termi
-
nal  on  the  amplifier  binding  post,  be  sure  to  plug  the  negative  lead  into  the  black  terminal  and  positive  lead  into 
the  red  terminal.  Ensuring  proper  polarity
  will  avoid  speakers  being  out  of  phase,  that  can  cause  a  loss  of  bass 
response.
Important Notice:  Banana Plugs - When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black 
caps on the binding post are completely screwed in. Insert the banana jacks into the caps of the binding post, be sure that the banana 
jack is inserted securely to avoid the risk of it popping out.Figure 8

Set Up
INPUTS - The V-01 Series amplifiers allow you to use two types of input connectors per channel, a XLR jack for balanced connections 
and a 1/4” female jack that will accept balanced and unbalanced connectors. Use these connections to connect the output signal from 
a mixer, cross-over or EQ to your V-01 
Series amplifier. A balanced connection is recommended for cable runs longer that 20ft. When 
constructing  your  own  XLR  cables  follow  the  pin  configuration  describe  below  for  proper  connections.  For  cable  runs  shorter  than 
20ft.  you  may  choose  the  1/4”  unbalanced  input  option.  The  1/4”  unbalanced  input  option  may  be  more  convenient  for  most  users 
due  to  the  abundant  supply  of  prefabricated  cables  available  at  your  local  audio  dealer.  You  may  use  the  two  XLR  “Input  Thru”  jacks 
to jump a parallel connection to another amplifier or other device. For Example: Connect a XLR cable to the input of channel one. You 
may now connect a XLR cable from the channel one “Input Thru” jack to the input jack of another amplifier’s channel one input. This 
will reduce the use of “Y” cables.

Spade Connector: (Figure 8)
When connecting your speakers to the amplifier using spade connector; Unscrew the red and black caps on 
the binding post, be sure not to completely remove or unscrew the red and black caps. Insert the spade con
-
nector in to the binding post and tighten the caps down on the spade connector. To reduce the risk of shock 
or  damage  to  your  amplifier,  be  sure  that  the  wire  connected  to  one  binding  post  does  not  come  in  contact 
with that of another. 
When connecting your speakers to the amplifier using banana jacks; Be sure that the red and black caps on 
the  binding  post  are  tighten  down  completely.  Insert  the  banana  jacks  into  the  caps  of  the  binding  post,  be 
sure that the banana jack is inserted securely to avoid the risk of it popping out.
Mono Bridge Connections:
Mono  bridge  operation  connections  will  follow  the  above  descriptions  however,  when  operating  in  mono 
bridge operation the speaker connections will run between the two positive (red) leads. Use channel two pos
-
itive output terminal for the negative connection and the channel one positive output terminal for the positive 
connection.

Stereo Connections Using the Neutrik Speakon output connectors:
Recent regulatory requirements in Europe have outlawed the use of the dual banana plug and force amp users to terminate their speaker 
cables  with  spade  lugs  or  bare  wire  ends.  This  is  not  advantageous  to  most  users  that  want  to  reconfigure  their  systems  or  quickly 
change  out  an  amp.  The  Neutrik  Speakon
® connector  provides  the  most  convenient  solution  to  this  problem,  eliminating  the  need  for 
spade plugs or bare wire end cables. Major speaker manufacturers have been using Speakon connectors on their products for years, 
so chances are you are ready to use the Speakon connection. With Speakon connectors, you can connect straight from the amplifier 
to the speaker. The Speakon connector used on this amplifier meets all known safety regulations. Once wired correctly, the connector 
cannot be plugged in backwards, causing the type of inverted polarity situations that have become common with banana hookups. This 
connection  will  provide  a  safe,  secure  and  reliable  method  of  connecting  your  speakers  to  your  new  amplifier.  You  can  purchase  the 
Speakon® NL4FC connectors from your local audio dealer.

Bare Wire Connections:  (Figure 7)
When  connecting  your  speakers  to  the  amplifier  using  bare  wire;  Unscrew  the  red  and 
black  caps  on  the  binding  post,  be  sure  not  to  completely  remove  or  unscrew  the  red 
and  black  caps.  Strip  back  the  wire  insulation  1/2”  (13mm).  Insert  the  bare  wire  into  the 
hole  that  was  reveled  by  unscrewing  the  binding  post  cap.  After  inserting  the  wire  into 
the binding post hole, screw the binding post cap down on the wire. To reduce the risk of 
shock  or  damage  to  your  amplifier,  be  sure  that  the  wire  connected  to  one  binding  post 
does not come in contact with that of another.

SPEAKON  ASSEMBLY:   You  will  need  a  pair  of  Neutrik  Speakon®  NL4FC 
connectors.  You  will  also  need  high-quality  two  or  four  conductor  speaker 
cable, a pair of needle-nosed pliers and a 1.5-mm Allen key to assemble the 
Speakon connectors to your speaker wire. To assemble the Neutrik Speakon 
NL4FC connector, complete the following steps:
1. Strip back 3/4-inch of the cable casing. Strip off 1/4-inch from the end of 
each of the conductors down to bare wire, and insert the brass fittings. See 
figure 11.
2.  Slide  the  cable  tension  clip  (D)  and  the  speakon  coupler  (E)  through  the 
cable end. See figure 12.
3. Insert each wire with the brass fittings into the top of appropriate slot of the 
connector insert (B) as shown in figures 12 and 13. Use a 1.5-mm Allen key to 
tighten the connection. See figure 13.
4.  Be  sure  to  properly  match  the  positive  (+)  and  negative  (–)  leads  of  each 
wire. See figure 14.
5. Slide the connector insert (B) into the connector housing (A), making sure 
that  the  large  notch  on  the  outer  edge  of  the  insert  lines  up  with  the  large 
groove on the inside of the connector housing. The insert should slide easily 
through  the  housing  and  out  the  other  side  until  it  extends  approximately  3 
/4-inch from the end of the housing.
6. Slide the cable tension clip (D) along the cable and insert into the housing 
(A),  making  sure  that  the  large  notch  lines  up  with  the  large  groove  on  the 
inside  of  the  connector  housing  (A).  The  cable  tension  clip  (D)  should  slide 
easily into the housing until only 3 /8-inch of the cable tension clip (D) extends 
from the back end of the connector.
7. Slide the coupler (E) along the cable and screw it onto the end of the housing 
(A). Before tightening, you may want to test the connector to make sure it has 
been assembled properly.

OPERATING MODES: Always configure  your amplifier operating mode before beginning operation. If you want to change it dur-
ing performance. You must
 decrease the gain controls to their lowest levels to protect the speakers from any popping noise.
Stereo  Operation  - Page 18/Figure  17  details  an  example  of  a  typical  stereo  set-up.  Connect  your  inputs  into  channels  one  and 
two of the amplifier. Connect your speakers to the outputs on the rear of the amplifier. Be sure that your front gain controls are turned 
down to their lowest level (full counter-clockwise). Turn your amp on. Turn your input source level up. Use your front gain controls to 
regulate the output volume. Be sure not to raise the volume to the clip level, however an intermittent clip signal is acceptable.
Mono Bridge Operation - Page 18/Figure 18 details a mono bridge set-up. Be sure your amplifier and all other audio equipment 
is powered down. Flip the Stereo/Mono Bridge switch to the Mono Bridge position. Connect an input signal to channel one. Connect 
your speaker across th
e red output binding post, or pin 1+, 2+ of channel one speakon output jack on the rear of your amplifier. Turn 
your  equipment  on  (your  amplifier  should  always  be  the  last  item  you  turn  on).  Apply  an  input  source  signal  to  your  amplifier.  Turn 
channel two gain up. Use the channel one gain to regulate your amplifier output.
Bridged-Mono Mode Caution - The voltage across the output terminals of a bridged V-01 Series™ amplifier may equal or exceed 
100 volts RMS and may be as high as 130 volts. Use fully insulated CLASS ONE wiring, and the load must be rated for up to 2500 watts 
(@4 ohms)
Parallel Mono - “Parallel ” ties the two channel line inputs together so that they will both be driven by the same signal, without the 
need for external jumpers or wiring. Both amplifier channels will operate independently. Though they carry the same signal, their gain 
controls  affect  only  their  respective  channels,  and  they  both  must  use  their  respected  speaker  outputs.  Never  attempt  to  parallel  the 
speaker  outputs,  this  may  cause  serious  damage  to  your  amplifier!  This  mode  is  recommended  when  using  the  V-01 
Series™ to  run 
bass speakers, to achieve better low end. To run in parallel mono mode connect your system as you would if you were going to run in 
stereo mode. Then flip the mode switch to “MONO.” Be sure the amp is off or the power is disconnected before making any changes.
Subwoofer Mode -  This mode sends low frequencies to your speakers without the use of an external cross-over. The subwoofer 
operation can be operated in stereo, mono, or bridge mono modes. Change the different operating modes by flipping the mode switch 
on the rear of the unit to your desired operating mode. Also, set the subwoofer mode switch to the subwoofer position. Use the frequency 
selector to adjust the subwoofer output frequency from 20Hz to 200Hz. The different subwoofer modes are listed as follows;
Bridge Subwoofer - This operation allows you to get the most possible power out of your amplifier  for the sole purpose of running a 
high powered subwoofer loudspeaker in mono. To avoid amplifier  overheating, never run the amplifier below 4 ohms in this mode. In 
this  mode  you  may  use  the  frequency  adjustment  on  the  rear  of  the  amp,  to  control  the  frequency  output  level.  Frequencies  may  be 
adjusted from 20Hz to 200Hz. Page 17/ Figure 15 details a typical Bridge Subwoofer set up.
Stereo Subwoofer -
  This operation is similar to the Bridge Subwoofer operation but in stereo. This operation allows you to run several 
subwoofers down to a minimum of 2 ohms. To avoid amplifier overheating, never run the amplifier below 2 ohms in this mode. Set up 
this mode as you would a standard stereo set up. Be sure both channels are set to “SUBWOOF.” In this mode you may use the frequency 
adjustment on the rear of the amp, to control the bass frequency output level. Frequencies may be adjusted from 20Hz to 200Hz. Page 
17/ Figure 16 details a typical Stereo Subwoofer set up.

Mono  Subwoofer  - This  operation  is  similar  to  the  Stereo  Subwoofer  operation  but  in  mono.  When  running  subwoofers  it  is  usually 
recommended  to  run  them  in  mono  mode  to  achieve  a  cleaner  tighter  low  end.  This  operation  allows  you  to  run  several  subwoofers 
down to a minimum of 2 ohms. To avoid amplifier   overheating, never run the amplifier  below 2 ohms in this mode. Set up this mode 
as you would a standard stereo set up. Be sure both channels are set to “SUBWOOF” and the mode switch is set to “MONO.” In this 
mode you may use the frequency adjustment on the rear of the amp, to control the bass frequency output level. Frequencies may be 
adjusted from 20Hz to 200Hz.
One  Channel  Normal/One  Channel  Subwoofer (BI-AMP)  -  You  may  also  use  your  amp  to  bi-amp  your  system.  You  may  use  one 
side of the amp to power a subwoofer and the other side to power a full range speaker. Follow the set up guides listed above to mix 
and match your operations.
PROTECTION:
Limiter  -  The  V-01 Series™  series  comes  with  a  built  in  limiter.  When  the  input  signal  overloads,  the  “CLIP  LED’s”  indicate  a  signal 
overload, at this time, the master volume should be lowered to reduce distortion. If the input gain level is not reduced the built-in lim
-
iter  will  activate.  During  signal  overload,  the  limiter  will  reduce  the  input  audio  signal  enough  to  minimize  the  amount  of  clipping.  A 
limiter takes the gain of an overloading signal and reduces it, the reduction in gain reduces distortion that can cause damage to your 
speakers  and  amplifier.  During  normal  operation  below  clipping,  and  momentary  clips  on  peaks,  the  limiter  does  not  affect  the  audio 
signal and is inaudible. It will allow brief clipping of peaks and will only activate when continuous, hard clipping occurs. During exces
-
sive  clipping  the  limiter  will  reduce  the  audio  signal  enough  to  minimize  the  amount  of  clipping.  When  the  input  signal  decreases 
enough  that  clipping  ends,  the  limiter  will  deactivate  and  cease  its  gain  reduction.  The  limiter  has  a  fixed  threshold  and  can  not  be 
adjusted. 
Safe Power Levels at Different Output Loads:
8-Ohm  Loads:   The  amplifier  can  operate  at  practically  any  power  level  without  risk  of  overheating.  However,  if  it  is  pushed  hard 
enough to continually light the “CLIP ” indicator, the amplifier’s average output power can reach 150 watts.
4-Ohm Loads: If the “CLIP” indicator flashes occasionally, the amplifier is approaching its maximum long-term power capacity. If it is 
lit about half the time, the amplifier channel will probably go into thermal protection within a few minutes.
2-Ohm  Loads:  Except  for  an  occasional  flash,  keep  the  “CLIP”  indicator  dark  to  avoid  overheating  the  amplifier  channel.  Clipping 
should be kept to a reasonable minimum. An amplifier’s peak current draw at full output power into 2 ohms is several times what the 
“normal ” draw is, but its various protection circuits will prevent this condition lasting more than a minute or two.
Short  Circuit  Protection  -
  The  V-01 Series™  series  amplifiers  all  come  with  built-in  Output  Short 
Circuit  Protects.  The  Output  Short  Circuit  Protection  protects  the  output  devices  of  the  amplifier 
from short circuits and stressful loads. If your speaker lines short, the amplifier automatically detects 
this  problem  and  discontinues  operation  for  that  channel.  If  one  side  of  your  amplifier  becomes 
shorted  and  goes  into  protect  mode,  the  other  side  will  continue  to  operate  normally.  During  short 
circuit  protection,  the  "Clip"  LED  and  “Protect"  LED  will  light  simultaneously  indicating  amplifier 
fault. All channel output  during the “Short Circuit Protection" will be interrupted (i.e. no sound out

put). Short Circuit Protection can usually be traced back to the signal output line (i.e. speaker line). Check the line from the output ter-
minal of the amplifier to the speaker. If this line good, check the internal speaker connections and components. A short circuit will usu
-
ally be traced to a bad cable or a bad speaker component and is rar ely traced to the amplifier itself.
Thermal Protection -
 Dual variable speed fans on the V-01 Series amplifier  provide adequate cooling. During low level output the fans 
run  at  normal  speeds.  During  high  output  and  as  heat  raises,  (exceeding  90°C.),  the  fans  will  run  at  higher  speeds  to  aid  the  cooling 
process.  If  the  heatsink  temperature  exceeds  91°C.,  the  amplifier  will  mute  until  the  amplifier  cools  down.  When  the  amplifier  cools 
below  90°C.,  the  amplifier  will  return  to  normal  operations.  Be  sure  not  to  operate  your  amplifier  below  the  minimum  load  ratings  to 
reduce the risk of overheating problems.
Input/Output  Protection  -
  The  input  circuits  are  isolated  by  10k  resistors.  An  ultrasonic  network  uncouples RF  from  the  output  and 
helps keep the amplifier stable with reactive loads.  
Operating  Voltage  (AC  Mains)  -  The  serial  number  label  indicates  the  correct  AC  main  voltage.  Connecting  to  the  wrong  voltage  is 
dangerous  and  may  damage  the  amplifier.  Always  be  sure  the  source  voltage  for  your  areas  matches  the  required  voltage  for  your 
amplifier.
Gain  Controls  -  The  gain  controls  are  located  on  the  front  panel  and  are  calibrated  in  2dB  of  attenuation  from  full  gain.  It  is  best  to 
adjust the amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion 
during normal operation. 
AMPLIFIER FEATURES:
THRU - Thru will allow the user to daisy-chain one amplifiers signal input into another amplifier. Plug the signal source outputs into the 
first amplifier’s input, patch from the amplifier’s THRU jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers 
as there is no excessive level loss. Is not affected by crossover setting.
GROUND LIFT SWITCH - Applying or lifting the ground switch will change the level for background noise and hum, if the noise level 
remains the same in either position, it is better to keep the ground lift switch in the ground position. This will eliminate 60Hz cycle hum 
that is sometimes induced when mounting several units in the same rack.
OPERATING VOLTAGE (AC MAINS) -  The serial number label indicates the correct AC main voltage. Connecting to the wrong voltage 
is dangerous and may damage the amplifier.
GAIN CONTROLS - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to 
adjust the amplifier so no  “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion 
during normal operation.
LED INDICATORS - Each channel has five LEDS. Two LEDs indicate signal level activity; one green LED and one yellow LED. One red 
LED indicates signal clipping. One red LED indicates protections mode for shorts/ overload. One green LED indicates an active signal. 
Both channels will also share the center blue LED that indicate the amplifier operating mode.
