DS8000 Architects' Specifications
The audio distribution system 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 +26dBu without clipping. Each channel shall
provide switched gain adjustment in 9 steps via a
front panel control, 48V phantom power shall be selectable
via a front panel switch, 4 segment LED metering and
'Solo' facility via a front panel switch. Phantom
power shall be remotely enabled when 48V power is
detected on the 'Mon' or 'FOH' XLR connectors on the
rear panel.The device shall include a headphone 'Solo'
facility via a 1 / 4 inch phone connector with associated
Remote phantom power and front panel phantom power
switching may be disabled via rear panel 'Safe' switches.
Ground lift switches shall disconnect the internal
ground connection in two banks (inputs 1-4, 5-8).
An 'OB Split' function shall feed input 1 to outputs
1-4 or input 5 to outputs 5-8 via two rear panel switches
with front panel indication.
The unit shall have the option to have AES digital
outputs fitted in addition to the standard analogue
outputs. 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 90-240V 50/60Hz
power supply. A single unit shall be capable of providing
power to another connected unit via a 5 pin XLR power
link cable, and this switchover shall be automatic
with front panel indcation of the power supply state.
The audio distribution system shall be the XTA Electronics
