User manual TASCAM KAMESAN KS-342

[. . . ] 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. If there are mistakes in the connections, it is possible that either the KS -342 or the other unit(s) will be damaged. [. . . ] 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, always make sure the case clips (four in all) fit over the lip at the top of the mixer front panel. 7 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 damage caused by shock or vibration. 8 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. 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 microphone to the 1 and 2 inputs. Battery locking lever Pull down to release the battery 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 auxiliary 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. 9 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). 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 rotary 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 10 KS-342 used as direct outputs from channels 3 and 4). 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). SOURCE SELECT switch This allows the choice of whether the MAIN and SUB connectors above output the mixed left and right output busses (MIX), or whether they output the individual channels in pairs (DIRECT OUT). AES/EBU The KS -342 is capable of outputting the stereo output in AES/EBU format.
