AMC403 - MONITORING & HEADPHONE AMPLIFIERS   Audio Monitor - 4 channels - Mute - HP output / headphone / Line On several STUDIO machines, manufacturers have removed the local monitoring control. AMC 403 makes up for this lack, ingiving to the operator the possibility to monitor, control or settle a local source. The operator will also be able to check level and phase. A start interface allows to create pulses or hold states for all types of machine, and to keep the automatic mute when it goes on air. The control modulation is available either in amplifier output for passive speaker, or under +6 dBu format for amplified speaker. The four inputs are mixed and an Antenna red interface affords to transfer the whole to a micro openning. A stereo synchronous output of the mixing is also available. Application * Pre monitoring control for four machines with START interface. * Line monitoring. * Level and phase control on four lines.
