The Kamesan KS-T2000 can use any standard type of battery: 
manganese, alkaline, nickel-cadmium, nickel-hydride or lithium-
ion. Four type 3 (AA) size batteries are required.
In normal use and temperature conditions, a set of alkaline bat-
teries will provide between five and six hours of operation.
In addition, the Kamesan KS-T2000 can accept power from a 
suitable power adaptor (described in “Using an AC adapter” on 
page 14).
The three-segment LED display by 
the power switch (top right of the 
front panel) gives the battery status 
as shown in the illustration here.
The number of LEDs lit shows the 
battery status. When only the bottom orange LED is lit, it is time 
to replace the batteries with a new set (30 minutes to 1 hour’s 
battery life remains).
If there is no battery life at all, none of the LEDs are lit, and the 
batteries should be replaced immediately.
If the unit is not to be used for an extended period of time, remove 
the batteries from the unit. Do not leave dead batteries in the unit.
The batteries are contained in a standard battery holder, which 
slides out for easy replacement. Additional battery holders can 
be purchased and “ready-loaded” with spare batteries for easy 
replacement.

1.Remove the cover on the left (INPUT) side of the unit. You 
may need to remove the touch fastener case strap to access 
the holder door.
2.Open the door using the catch located by the red (+) mark, 
and remove the battery holder as shown above.
3.Remove any old batteries in the holder and place new batter-
ies in the holder.
 Take care that the batteries are inserted correctly as shown 
above, with the polarity correct.
 Never mix batteries of different types, or discarded (or par-
tially-discharged) and new (or freshly-charged) batteries.
 Always follow the battery manufacturer’s instructions for 
charging rechargeable batteries. Never attempt to recharge 
batteries which are not designed for this purpose.
4.Replace the battery holder into the Kamesan KS-T2000 and 
close the battery door. Replace the case strap in its original 
position.
The battery holder should be inserted with the end with two battery 
contacts entering the compartment first, and with the single metal 
rivet towards the hinge of the holder door (as shown in the illustra-
tion above.
5.Test the battery power and polarity with the power switch 
(see “Checking the batteries” on page 12).

Note that when new batteries are inserted, the indicators may show 
the middle or low battery condition. This is because the power LEDs 
monitor the actual real-time battery usage, and when the unit is ac-
tually in use (phantom power, headphone amp, etc.), the true bat-
tery status will be shown.
 Do not use the VU meter light more than necessary (this can 
result in considerable savings).
 Turn off the power to the Kamesan KS-T2000 when it is not 
in use (“resting” the batteries can increase the battery life 
very significantly).
 Setting the XLR output level switch to the +4 setting can 
reduce battery consumption.
 Cold batteries have a shorter life than warm ones. In winter 
or other cold conditions, you may want to keep the batteries 
warm when they are not in use. At 0°C (32°F), battery life is 
about 60% less than at 20°C (68°F).
 As long as the connector conforms to the polarity of the 
Kamesan KS-T2000 connector (tip negative), a BP-90-type 
battery can be used for external power of the mixer.
The Kamesan KS-T2000 can use one of two optional external 
adapters:
 PS-M12 mini power supply
 SS-40611 MkII low noise power supply
Alternatively, any other power supply may be used (although this 
is not recommended), provided that it conforms to the following 
specifications:
Connector: BP-90 type with tip negative
Voltage: >9.0 V and 0.5 A
 Any non-Kamesan AC adapter should also incorporate ripple 
reduction circuitry.

The use of any adapter other than the type specified here may re-
sult in damage to the Kamesan KS-T2000, other equipment, or 
even result in overheating and fire. For this reason, it is essential 
that only those adapters recommended and sold by Kamesan are 
used.
Connect the adapter connector to the DC IN connector of the Ka-
mesan KS-T2000, making sure that the polarity of the adapter 
connector matches that of the Kamesan KS-T2000.
 When DC power is supplied to the Kamesan KS-T2000, this 
takes priority over any internal batteries (which are not used 
when the adapter is connected and power is supplied). When 
the adapter is disconnected, the batteries are used again.

The following explains some of the principles of operating the 
Kamesan KS-T2000 when all the connections have been made:
Adjust the relative levels of the inputs by using the level controls 
(faders).
Turning these controls fully counterclockwise attenuates the sig-
nals, and turning them fully clockwise boosts them.
The nominal position (neither cut nor boost) is marked as shown 
here.
To make the best use of the Kamesan KS-T2000’s gain structure, 
we recommend setting the channel fader control to this nominal 
position, and adjusting the trim level to obtain the appropriate 
reading on the VU meter (as described in “Adjusting the input 
gain” on page 17).
Each input can be assigned to either the left master output, the 
right master output, or both.
Use the L and R switches to send the input signals to 
the left and right outputs:
When these switches are in the up position, the input 
is assigned to the appropriate output bus.
The Kamesan KS-T2000 provides three low-cut (high-
pass) filters at 160 Hz with a slope of –12 dB/octave. 
Use these independently-switchable filters (one on each 
channel) to counteract the effects of wind noise, rumble, etc.
Set the switch to the up position to engage the filter.
Use the headphone jack to monitor the outputs.
The volume output from the headphones is adjusted with the 
(yellow) control.

The signal or signals being monitored and metered are set using 
the (green) monitor selection control.
The [L+R] setting is also used for the external monitoring source 
(see “External monitoring input” on page 8).
Before adjusting the inputs:
1.Make sure that the correct input mode has been selected 
(“Input connections” on page 7).
2.If the low-cut filter is to be used on the input channel, make 
sure that it is enabled (“Low-cut filtering” on page 16).
3.Ensure that the input is routed appropriately (“Routing the 
inputs” on page 16).
4.Ensure that an appropriate monitoring mode is selected 
(“Monitoring” on page 16).
5.Turn down all input faders, 
except the one which is to be 
adjusted, which should be set to the nominal position.
6.While the input sound is being input through the micro-
phone, etc., turn the channel’s input gain control so that the 
VU meter indicates a healthy level (not into the red, but 
“kicking” the 0 mark is fine).
7.When the level has been set up to your satisfaction, turn the 
channel’s input fader all the way down, and repeat the pro-
cess for all the other channels in turn.Monitoring switch settings

The gain level for all types of microphone ranges from –30 to –
70 dBs (marked in white; the –40 and –50 points are marked for 
convenience), and the gain level for line-level sources ranges from 
–20 to +4 dBm (marked in blue).
The head and mixer amps of the Kamesan KS-T2000 allow con-
siderable leeway. On the input stage, there is about 28 dB avail-
able, and on the output stage, about 17 dB is available
To help you match the levels of the Kamesan KS-T2000 with the 
recorder connected to the outputs, the mixer is fitted with an in-
tegral 1 kHz line-up oscillator.
In order to see the output level using the oscillator:
1.Make sure that both the OUTPUT level switches are set to the 
correct value (usually +4).
2.Turn the power on (up), and then turn the oscillator switch 
on (up).
3.To monitor both channels together, set the monitoring selec-
tion switch to the L/R setting (see “Monitoring” on page 16 
for an explanation of the monitoring switch settings).
4.Adjust the level of the outputs so that the VU meter reads 
0dB.
5.Remember to turn the oscillator off when the adjustment 
has been made.
