6 KS-342 Before operating the Kamesan KS -342, you should be aware of the following points: All XLR -3 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 at- tempt to make any connection to this jack except using AC adaptors authorized by Kamesan. Always remove any dead batteries immediately from the Kamesan KS -342, 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. About the manual Keep this manual in a convenient location for handy reference. Any labels on the unit mentioned in the manual are shown this typeface: OUTPUT. Sometimes you will see a note—important information which you should note. NOTE Failure to read and observe notes and warnings may result in personal injury and/or possible damage to the unit. Batteries and power The Kamesan KS -342 can use any standard type of batter y: manganese, alkaline, nickel - cadmium, nickel - hydride cells fit- ted in a BP-3/8 batter y holder (supplied with the KS -342) or a special NP-1 NiCd batter y pack. Eight type 3 (A A) size batteries are required. In normal use and temperature conditions, a set of alkaline bat- teries provides about six hours of operation. See the specifica- tions at the end of this manual for more detailed information. In addition, the Kamesan KS -342 can accept power from a suitable power adaptor connected to the DC power input. This power should be between 10 V and 15 V DC, with a maximum current of 500 mA. The connector is tip negative.
7 KS-342 NOTE 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 batter y holder, which slides out for easy replacement. Additional batter y holders can be purchased and “pre - loaded” with spare batteries for easy and speedy replacement. Accessories, etc. The Kamesan KS -342 is supplied with ever ything 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 batter y holders, allowing you to slip in a new power source at a moment’s notice. Use the BP-3/8 batter y holder for dr y cell batteries, and the BH -1 for the NiCd NP-1 batter y. To expand the capabilities of the unit further, it is possible to fit a KS - 6001 4 - channel sub - mixer, and/or a KS - 6002 4 - channel EQ/compressor unit, both of which integrate neatly into the KS - 342 system without the use of cables. Consult your Kamesan supplier for details. About the case The Kamesan KS -342 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. You can loosen the straps on the case in order to expand the case size and allow the side strap holders on the mixer to be freed from the retaining panels in the case. If you remove the mixer from the case, and then replace it, al- ways make sure the case clips (four in all) fit over the lip at the top of the mixer front panel.
8 KS-342 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 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. In addition, it can form a convenient rain hood, allowing easy access to the front panel controls while protecting them from the elements. Also note that if the KS - 6001 sub - mixer or the KS - 6002 EQ/ compressor is fitted, cushioning material is supplied, allowing the extra units to fit snugly, and minimizing any possible dam- age caused by shock or vibration.
9 KS-342 Features and panel items For the most part, the explanations given for the individual parts of the KS -342 will allow you to operate the mixer effec- tively. You should therefore read this part of the manual care- fully in order to understand the many features and operations possible with the unit. Left side (viewed from front) This section is chiefly the inputs to the mixer: ������������������������� ������������������� ����������� ���������������������� ��������� ����� ������� ������������ ���������� ������������ �������������� INPUTS 1 through 4 Connect the microphones or line level sources to these XLR jacks. INPUTS 1+2 This XLR - 5 jack is used to connect a stereo mi- crophone to the 1 and 2 inputs. The wiring is: 1= ground, 2= L +, 3 = L –, 4 = R +, 5 = R –. Battery locking lever Pull down to release the batter y pack Coaxial power supply Connect a suitable power supply (tip negative, between 10 V and 15 V, approximately 0.5 A). DC 12 V OUT This connector is used to supply external power to other equipment. AUX IN This connector is used to connect an auxiliar y input, such as a camera’s audio signal, etc. Aux level control and routing switch The level control is used to set the level of the input aux signal when it is routed to the output busses.
10 KS-342 The routing switch sends the aux signal to the L and R main out- put busses (AUX MIX) or to the monitor bus only (AUX MONI) or completely off (center position). Right side (viewed from front) This section is chiefly the outputs from the mixer: �������������������� ������ ��� ������������ � �� � ��� ����� �� �������� ��������� ��� ��� ������ ��� ��� ���������������������������������������������������������������������������������������������� ������������� ������ � ����������� �������� ����� ����������� �������� ������� ������� ����������� �������� �������� ���������� ������ ����������� ����� �������� ������ MAIN outputs L and R Balanced XLR -3 connectors providing the main analog output signals from the KS -342. They can also be used to provide the outputs from input channels 1 and 2, for example when these are used in MS mode. MAIN level controls Use these rotar y controls to adjust the level of the signals sent from the main outputs. MAIN compressor controls The main output busses can be compressed using the onboard compressor (this applies to all outputs fed by the output busses. The triggering of the compressor can be done by either the L or the R bus, or ST LINK setting, in which either bus can be above the trigger level, or L•R in which both busses must be above the trigger level (the off position is represented by the • symbol). The trigger level itself can be set to +3 dB (3), + 6 dB (6), +9 dB (9) or +12 dB (12). SUB output This XLR - 5 connector provides the main output busses as balanced sub outputs (or this connector can also be
