DS800 Architects' Specifications
The mic/line distribution unit shall be of an active design providing 8 independent channels in a standard 2 unit, 19" rackmount enclosure. Each channel shall provide two outputs that are actively balanced, and accessible via rear panel XLR connectors, and two that are transformer isolated and accessible via front panel XLR connectors.
The input shall accommodate line level signals of up to +30dBu without clipping. Each channel shall provide gain adjustment to five settings via a front panel switch, Mic/Line switch, 48V phantom power selectable via a front panel switch, 5 segment LED metering and 'Listen' facility via a front panel switch. A -10dB pad shall be activated for each channel when 48V power is detected on the 'Mon' XLR connector on the rear panel.The device shall include a headphone 'Listen' facility via a 1 / 4 inch phone connector with associated level control.
The device shall provide facility to link the 'Listen' busses together when using multiple devices. The device shall be powered from an internal power supply, which will operate from an 80-250V 50/60Hz power supply. The mic/line distribution unit shall be the XTA Electronics DS800.
