Drawmer DA-6 EX Distribution Amplifier

The stereo Input features individual left/right level controls with LED bargraph metering enabling the correct balancing of stereo material or two mono signals. Each of the six outputs incorporate further left/right level controls and a Mono/Stereo switch providing the selection of either one stereo output or two mono outputs per channel. This feature allows the DA-6 to function as either a 1 x stereo input/6 x stereo outputs or 2 x mono input/12 x mono output unit or any combination of the two. The output section consists of a Channel Select so that the individual left/right output level of each channel is displayed on the output LED bargraph and can be monitored by the Headphone jack socket. A pair of auxiliary link stereo jack sockets (TRS) are provided via the rear panel for connection to further DA-6 units for the distribution of even more channels.
