2.1 Important Information for set up
After having unpacked your subwoofer\f please allow the system to acclimate to 
the temperature of the room for approximately an hour\b
The subwoofer should be positi\loned on a firm ground\b
We recommend retaining the original packaging\f as it is the best  way to 
guarantee safe transportation should the need to do so arise\b
Please note that the subwoofer will take some break-in time to achieve optimum 
sonic performance\b 
2.2  Quick Start
a)  Before connecting the Sub2100 to your audio components and the power source 
make sure that the subwoofer\f the satellite speakers and your audio source are 
switched off and set the level controls to minimum\b
\f)  Choose your preferred connection as d\lescribed under 3\b
c)  Check if the specified voltage matches the voltage of the power supply you use\b 
If this is not the case do not con\lnect the loudspeakers to a power source! Please 
contact your local dealer or \lnational distributor\b 
If the voltages match\f use the included power cables to connect the loudspeaker 
to the AC sockets\b
d)    Turn on your audio system and start your source of music\b
e)    Switch on the main on/off switch on the rear panel of the subwoofer and the 
main switches of the satellite speakers where required\b
f)   Turn up the volume levels of your audio system and of your satellite speakers 
carefully\b
 
g)    Adjust the Sub Level on the rear panel of the subwoofer to your liking\b

3.1 
Connections
On the rear side of the speaker you can find balanced (XLR) and unbalanced (RCA) 
connectors\b For professional use the XLR connectors will be the first choice\b 
3.2  Input
Connect the left and right line-le\lvel signal 
from your signal source (audio interface\f mixer\f 
etc\b) to the LEFT and RIGHT \lINPUT jacks\b Use 
either XLR (balanced) \lor RCA (unbalanced) cable\ls\b 
3.3  Satellite Out
Connect the LEFT and RIGHT \lSATELLITE OUT 
jacks to the inputs of the left and right main 
powered speakers or the inputs of the amps 
powering the main speakers\b
3.4  Su\f Out
This  balanced output mir\lrors the input signal enabling \lyou 
to daisy-chain as many Sub15s in a row as you like\b The Sub 
Level affects the output so  that all Subs in the chain can be 
levelled at once\b 
3. Connecting the Su\fw\coofer

It is common knowledge that low frequencies (below about 100Hz) are non-directional\f 
meaning they can hardly be located by the listener\b It is\f however\f a common misunder-
standing that therefore the placement of a su\lbwoofer does not matter\b It does matter\b
Due to the fact that every room (geometry\f furniture\f etc\b) is unique\f the following  de-
scriptions intend to  be a first introduction to the subject\b The aim is to assist you  tack -
ling the most common problems with subwoofers and room acoustics\f notably interfer -
ence and standing waves\b
4.1   Distance to satellites
In most set ups it is advisable to place the subwoofer not too far from the satellites 
to minimize the chance of  Interferences\b Interference means the superposition of 
two or more waves resulting in an attenuation/cancellati\lon or enhancement of the 
specific frequency/frequencies\b
Furthermore\f big refelexion faces in close range of the subwoofer should be avoid-
ed if possible\b
4.2   Walls/Distance to walls
Generally\f  every  wall  in  relative  close  distance  to  the  subwoofer  enhances  its 
sound pressure by about 6 dB\b For instance\f placing the subwoofer in a corner of 
a room will make it about 18 dB louder\b It is likely that this will result in an impair -
ment of the precision of the musical reproduction\b
Another  problem  related  to   the  geometrics  of  the  room  concerns  the  so  called 
‘standing  waves’\b  These  are  sound  waves  being  reciprocated  between  reflecting 
objects\f so they ‘stand’ (don’t seem to move) in between these objects\b The speak -
er continues to produce  new waves  that combines its force with the first wave(s): a 
vicious circle that results in local imbala\lnces of the particular frequencies\b
4.3   Finding the \fest position
Give  it  a  try!  The  most  important  tool  for  finding  the  best  position  for  your  sub-
woofer are your ears\b There are two rather easy ways:
You  can  determine  your  listening  spot  first  and  then  compare  the  sound  of  the 
subwoofer at different positions\b
Another option is to place the subwoofer at the listening position and then move 
around\b Whereever the sound is the best the subwoofer should be positi\loned\b

Sub2100 Manual / English
On the front side you will find Indicator LEDs for the operating and standby modes\b 
Controls  for  the  satellite  filter\f  phase  switch\f  signal  on/continous  mode   and  Sub 
Level/Filter  are  located  on  the  rear  panel  of  the  subwoofer\b  The  following  tips  are 
intended to assist you at using the controls in the best manner\b
5.1 
LEDs on front panel
There  are  two  LEDs  on  the  front\b  The  upper  LED 
indicates the operating mode\b In case the subwoofer 
receives  an  overload  the  lower  LED  will  flash  red 
indicating the function of the protective circuit\b 
5.2  Controls on the rear panel
a)  Su\fwoofer Phase
With  the  Phase  Switch  you  can  alter  the  phase  of 
the subwoofer relative to the satellites\b That means 
to  change  the  polarity  of  the  bass  unit\b  Depending 
on  the  distance  between  woofer  and  satellites\f 
either  0°  or  180°  may  be  the  better  position\b  We 
recommend  to  try  out  what  position  sounds  better 
within your system\b
\f)  Satellite Filter
The  satellites  in  a  system  can  be  driven  full  range  or  with  a  85  Hz  high 
pass  as  recommended  by  Dolby®  laboratories  for  use  in  surround  setups\b 
Recommendation:  the  main  signal  should  go  into  the  Subwoofer\b  Connect 
your  satellites  to  the  Subwoofer  output\f  either  via  XLR  symmetrical  or  RCA 
asymmetrical\b In many cases\f clarity and dynamic range of the speakers can be 
improved if they do not reproduce very low frequencies since they do not have 
to deliver big amplitudes\b 
Please note: If you alter the frequency  it is a\fvisable to check if an alteration of the 
\bhase im\broves the soun\f quality.
5. Controls

5.2 Controls on the rear panel (continue\cd)
c)  Su\f Level
In the 0dB position the signal will be passed on 1:1 
to the internal amplifier\b The Input Sensitivity of the 
subwoofer  can  be  adjusted  from  -60dB  to  +6dB 
and thus allows for a wide volume levelling range\b 
d)  Su\f Filter
The upper frequency limit of the unit is variable and can be set to any value 
between 50 and 150Hz\b The 85Hz marker indicates the recommendation 
of  Dolby®  labs  for  surround  sound  settings\b  In  practice  a  slightly  lower 
crossover  frequency  delivers  tighter  bass  response\b  For  typical  near- 
midfield monitors we recommend 70 to 75Hz as the upper limit\b
Please  note:  These  settings  \fo  not  have  an  absolute  character,  as  \fifferent 
satellites an\f \fifferent room acoustics lea\f to results that cannot be \bre\ficte\f.
