XTA DS800 distribution amp

Now available for hire/rental

The DS800 is an 8 input, 32 output self contained audio distribution system. In standard format each input is split into two transformer-isolated outputs (-10dB level) and two actively balanced outputs.

The unit can be internally reconfigured to give more than the standard four outputs from each input up to a total number of 32 outputs.

Each input features remote activated pad, adjustable gain, mic/line switch, 48V phantom power, 5 segment LED metering, 'listen' facility.

A headphone output and associated gain control are also provided. When using multiple units the 'listen' facility can be cascaded such that any input channel may be listened to via a single headphone output.

DS800 Features

• Self-contained, 8 input 32 output unit with auto switching powersupply, will work down to 60V mains voltage, 50/60Hz, no external power supply needed.
• Ergonomically designed front panel with recessed controls resulting in a 'cable and connector free' control area.
• 5 segment LED meters on every input giving instant indication of input levels and or clipping.
• Exceptional dynamic range.
• Headphone 'listen' facility, which can be expanded when usingmultiple units.

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.
