Formula Sound Mixer 19" 7U Blue 8 Inputs

The FSM-400 is primarily aimed at the professional DJ but will also be used in smaller installations where a four channel mixer with each channel switchable to two inputs can be utilised. Channel 1 is switchable between low impedance microphone and stereo line inputs. Phantom power is available for microphones (internal selection). Channels 2 to 4 are switchable between A and B inputs. The A input may be internally configured to be either an RIAA equalised input for a magnetic phono cartridge or a normal line input to accept CD, tape etc. The B input is always a normal line input. Three band equalisation is fitted to all inputs. The range is +5dB to -20dB. The amount of large cut eliminates the need for frequency cut switches and is available on all channels allowing creative mixing. Channels 2 to 4 have internal jumpers to provide 2 gain settings per input. The gain range is - normal 15dB or low setting +2dB to -19dB. Push button switches are used for input selection, PFL (pre fade listen) routing etc. and a smooth 60mm fader, which is arranged to eliminate the ingress of dirt, complete the channel controls. The output section provides plenty of facilities to cope with most applications. It includes a new design of crossfade circuitry that places less demand on the fader to ensure exemplary attenuation and extended life. A punch button facility is also included. Illuminated push buttons, led meters and indicators are fitted throughout to provide the operator with good visual indication of the mixer status. Unlike the majority of fixed format mixers on the market all connectors are fitted to the back face which allows unrestricted access when the mixer is fitted through a work top or console.
