Treat your Kamesan KS-T2000 in the same way that you would 
treat any piece of precision equipment. Although it is designed 
for rugged location use in a wide range of extreme conditions:
• Avoid spilling liquid over the unit or exposing it to extremely 
humid environments. 
 Do not subject the unit to extreme temperature changes, as 
this may cause internal condensation, affecting the opera-
tion of the unit.
 Avoid operating the unit in extreme temperature conditions 
wherever possible.
 Avoid using the unit in dusty or smoky locations wherever 
possible
 When cleaning the unit, never use solvents or thinner to 
clean the outside of the case. Only use a soft damp cloth to 
wipe off any dirt or stains.
 Only use power supplies (batteries and external power sup-
plies) as recommended in this manual.
Connection of microphone cables and microphones: to prevent 
hazard or damage, ensure that only microphone cables and micro-
phones designed to the IEC 268-15A standard are connected.
Connexions des microphones et de leurs câbles: pour éviter tout 
endommagement, s’assurer de brancher uniquement des micro-
phones et des câbles de microphones conçus selon la norme IEC 
268-15A.
 When using microphones, make sure that the phantom 
power is set appropriately for the microphones. Use of +48 V 
phantom power with microphones not designed for this may 
result in damage to the microphones, and to the Kamesan 
KS-T2000.
In the event of encountering problems with the Kamesan KS-
T2000, you should contact your local after-sales representative.

Before\
Before operating the Kamesan KS-T2000, you should be aware 
of the following points:
 All XLR connectors (male and female) are wired with the fol-
lowing pinouts: 1=ground, 2=hot, 3=cold.
 The AC adaptor jack is a tip-negative connection. DO NOT 
attempt to make any connection to this jack except using an 
AC adaptor authorized by Kamesan.
 Always remove any dead batteries immediately from the 
Kamesan KS-T2000, and remove any batteries from the unit 
if it will not be used for some time. Corroded and leaking 
batteries can cause severe damage to the unit.
Keep this manual in a convenient location for handy reference.
Any labels on the unit mentioned in the manual are shown in 
this typeface: OUTPUT.
Sometimes you will see a note—important information which 
you should note.
Failure to read and observe notes and warnings may result in per-
sonal injury and/or possible damage to the unit.

The Kamesan KS-T2000 is supplied with everything you need to 
start work.
However, you can purchase the following, in order to increase 
the capabilities and the functionality of the unit:
 Power adaptors: you can use the Kamesan PS-M12 mini 
power supply.
 Spare battery holders, allowing you to slip in a new power 
source at a moment’s notice.
The Kamesan KS-T2000 case is designed to hold and protect the 
unit against any wear and tear under the standard conditions of 
use for which the mixer is designed. In addition, the mixer itself 
has been designed to be rugged and to stand up to the demands 
that will be made of it in its expected life.
Even so, you should not drop the mixer, or subject it to violent 
shocks or vibration. Always keep the mixer in its case to avoid 
any possible damage.
If you remove the mixer from the case, and then replace it, al-
ways make sure the case clip fits over the lip at the top of the 
mixer front panel.
The touch fasteners at either side may be used to tidy cables, as 
well as to restrain the mixer in its case.
You can use the side pocket in the case to store spare batteries, 
adaptors, etc.
You can secure the top flap using the touch fastener when it is 
folded back to allow operation of the front panel.
Accessories, etc.

The Kamesan KS-T2000 controls and connections can be divid-
ed conveniently into three sections: the input section, the out-
put section, and the front panel.
The input side of the unit (on the left as you look at the front) is 
as follows):
Always make and break connections to and from the Kamesan KS-
T2000 with the power to the mixer and to all other equipment 
turned OFF.
The mixer can accept a number of different sources at the three 
XLR input jacks. The type of input for each channel is selected 
using the channel input mode selector rotary switches:

Connect balanced cables from microphones to the XLR inputs, 
and set the switches appropriately:
Always make sure that the input mode selected for each channel 
matches the device connected to the channel BEFORE turning on 
the power. Selecting the wrong type of device could result in dam-
age to equipment. If you have to change the input mode with the 
power connector, turn down both the input level faders and the 
monitoring level before changing the input mode.
For full details of the levels, impedances, etc. of these jacks, see 
the section on “Specifications” on page 19.
The illustration above shows the Kamesan KS-T2000 connected 
to a pair of microphones as well as to a wireless receiver. 
Note that there is one more input connection ( the external mon-
itoring input) which may be made to the Kamesan KS-T2000, as 
explained below:
The Kamesan KS-T2000 allows you to input a stereo signal via a 
mini 3.5 mm jack to the MONI IN input. This signal should be at 
a nominal –10 dBV level.
The front panel switch controls whether this output is monitored 
or not through the headphones. The level cannot be changed.

There are two sets of connections available from the Kamesan 
KS-T2000: the main balanced connectors and the unbalanced 
RCA connectors.:
You can use these different connectors for professional and 
semi-professional video equipmen
When you make the connections to the balanced connectors, 
note that there are two switch positions for the level of these out-
puts: +4 and –60. Make sure that you make the appropriate level 
setting for the device connected to the Kamesan KS-T2000.
