Kamesan KS342
4-Channel Compact Location Mixer

KS342

No two location projects are ever the same, and often, they make demands beyond traditional sound mixing techniques. So in the first place, the KS-342 offers uncompromising operation and performance. Then additionally, its unique expansion modules ensure you have specialised tools at your fingertips to deal with the most challenging productions. This is a mixing solution as versatile as you are.

Extensive Input Facilities
To accommodate any signal source, a front panel switch selects between line or microphone inputs, providing 12 or 48 volt phantom powering as required. Level trim at both sensitivities means the main channel faders can be set at optimum rotation for normal working. Massive 30dB pre-fader headroom plus continuously variable hi-pass filtering ensure signals never get out of hand. Channels can be ganged for true stereo operation and switched to the left or right mix busses.

Multiple, Multi-level Outputs
Thumb-knob master level controls prevent accidental adjustment and the signal passes through switchable compressors before the final output stages. Fast attack, compound release circuitry provides a comfortable safety margin for distortion free operation. Independent as well as ganged settings ensure maximum flexibility for stereo and dual mono setups. This design philosophy is carried through to the isolated outputs which are not a luxury but a necessity in many situations. With a choice of levels (left right independent), symmetry and connectors, four isolated two channel feeds are provided. Furthermore, an internal, 96kHz sampled, AES/EBU compliant digital converter delivers the highest quality output when required.

Comprehensive Monitoring
This degree of flexibility has to go hand in hand with the capability to monitor signals accurately. Backlit, jam-proof, level meters offer clear visual indication of the main output signal. The headphone circuit can be switched to monitor any combination of the outputs in mono or stereo and MS decoding. Additionally, an indispensable PFL function which appears on the right meter as well as at the headphone output is included. Where are the individual channel switches located? Simply 'press' the corresponding HPF control knob to activate!. A built-in slate microphone is also featured.

Smaller, Lighter, Better Powered
Just as much attention has been paid to the mechanical and powering design as to the electronic circuitry. Smaller and lighter than any comparably featured mixer, the front and side panels are uncluttered and easy to use. The all important channel faders feature latex knobs for all temperature comfort and are easily gripped, even in gloves. Kamesan's trademark bar-grip knobs are used for all presets and never obstruct easy operation. Internal powering is by 8 'AA' cells in a 'quick change' pack; or by way of an optional clip-on housing (BP-1) which accepts the industry standard NP-1 camcorder battery. Low power consumption typically provides up to 8 hours of operation. In fact, any raw DC up to 16V can be applied to the mixer power circuit which also provides an auxiliary regulated output, useful for powering receivers etc.

Designed With Expansion In Mind
The nature of location recording is that there will always be situations which require more channels or more processing. In the first place the KS-342 features a multiway link socket which can be used to cascade a stereo input from another mixer without sacrificing channels. Secondly, a discrete connector and sturdy locks, attach and integrate a range of specialised modules which expand capabilities instantly. Currently two variations are available; the KS-6001, a four channel sub mixer with identical input features and the KS-6002, a block of four parametric equalisers and compressors. The inclusive all-weather case, crafted from 'wet-suit material, expands to accommodate up to two optional modules and comes complete with shoulder strap, waist belt and rain covers.
