11 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. SOURCE SELECT switch This allows the choice of whether the MAIN and SUB...

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.

15 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 repre- sents 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. In...

16 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 pro- vides 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. These modular connectors allow you to build up a portable...
