543 Voltage Controlled Output Mixer

Four-channel VCA/panning mixer with metering, headphone amp, A-440

The 543 is a four-channel output mixer, which can be used to sum up audio material as well as control voltages. Its signal paths are equipped with volume and panorama controls. Thanks to CV inputs, it is also possible to modulate both parameters. (Volume: 0 V to +10 V; Panorama: -5 V to +5 V) On top, there is a mute switch per channel.

On the output side, there are master and headphone connectors. Both stereo channels can be leveled individually. The main signal paths may be (de)activated via a switch. Two large VU meters visualize the volume of the master channels. Headphone signals can be tapped in front or behind the main level control. Another feature of the 543 is a 440 Hz reference tone generator.
