KS-342 Notes on the Operating Environment Avoid using this unit in places with high heat or high humidity as damage or malfunction may result. When using in an exceptionally cold environment, battery service life may be shortened, and there may be a drop in performance. If at all possible, use this unit in the temperature range as indicated in the specifications. When connecting this unit to external devices, be sure to read all related operation manuals and connect the devices correctly to each other.

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 following 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 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.
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 battery holder, which slides out for easy replacement. Additional battery holders can be purchased and “pre-loaded” with spare batteries for easy and speedy replacement. Accessories, etc. The Kamesan KS -342 is supplied with everything you need to start work.
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.
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 effectively. You should therefore read this part of the manual carefully in order to understand the many features and operations possible with the unit.
KS-342 The routing switch sends the aux signal to the L and R main output busses (AUX MIX) or to the monitor bus only (AUX MONI) or completely off (center position).
KS-342 used as direct outputs from channels 3 and 4). The wiring is: 1 = ground, 2=L+, 3 = L–, 4=R+, 5=R–. There is a choice of output levels: –20 dB or –60 dB, selectable by the switch immediately below this connector. ST OUT This unbalanced 3.5 mm stereo jack output provides another stereo output for feeding unbalanced inputs (on a camera, for example). The level is –60 dB.
KS-342 Front panel The front panel is where you will make the majority of the settings while you are using the KS -342.
KS-342 time, but in this case, the level and right VU meter indication will be lower than the actual values. Channel faders The nominal position is at about the 2 o’clock position, when the fader is pointing to the channel number. NOTE In MS mode, faders 1 and 2 have a slightly different meaning, as explained in the appropriate section. Slate microphone This built-in microphone allows the operator to make comments, or clapperboard, etc. signals to be added to the main mix.
KS-342 2. Turn the power on (up), and then turn the oscillator switch on (down). 3. To monitor both channels together, set the monitoring selection switch to the L/R setting (for an explanation of the monitoring switch settings). 4. Adjust the level of the outputs so that the meter reads 0 dB (or the equivalent, depending on the meter. 5. Remember to turn the oscillator off when the adjustment has been made. The center position is off. Master level controls Adjust the output level with these controls.
KS-342 VU scale These meters conform to the VU standard, providing an averaged level reading. 0 VU marks the reference position. BBC scale Developed by the British Broadcasting Corporation, this peak meter standard goes from 1 to 7 (each step represents 4 dB) with a fast rise and slow fall time. The reference level is “6”. Nordic scale Another peak meter type, with 0 again being the reference level, but the readings are from –42 to +12 dBu.
KS-342 Expansion The KS -342 may be used together with the KS - 6001 sub mixer, which provides a further four channels of input feeding the AUX bus, and/or the KS - 6002 compressor/EQ module, which provides sweepable 2-band EQ and compression facilities for each channel. The KS -342 can act as the power source for these units, which integrate neatly with the built-in connector on the top panel of the unit.
