All XTA products are carefully engineered for world class performance and reliability. If you would like further information about this or any other XTA product, please contact us. We look forward to helping you in the near future. [. . . ] This allows sufficient gain to be applied to low level signals, such as dynamic microphones, to avoid the poor noise performance often associated with active mic splitters. Phantom power (48VDC) is provided, and is switchable to each input by selecting 'Phantom Power' on the front panel. The DS800 is designed to reduce system grounding problems; please refer to the 'System Grounding' section further on in this manual for more information. DS800 Page 4 Front Panel Functions 1. Isolated Outputs ­ two identical transformer balanced outputs featuring high voltage isolation, for use as broadcast or recording feeds or wherever independent outputs are required. These connections are wired as follows :Pin 1 = No Connection, Pin 2 = Hot, Pin 3 = Cold. Gain Switch ­ sets the channel gain to +10dB, +20dB, +30dB, +40dB or +50dB. Mic/Line ­ when in the `Line' position the input is padded by 20dB and the input impeadance changes to >10k Ohms. 48V ­ when selected applies 48V phantom power to the input XLR, for condenser microphones or D. I. Meter ­ 5 segment level meter showing the level below clipping. Note: the red LED lights up 6dB's below actual clipping with a sine wave. Listen ­ when selected the channel will be summed on to the `Solo' bus, which is routed to the headphone socket and `Solo Out' XLR. Pad (-10dB) ­ indicates 48V phantom power detected on the output `Mon' XLR, which will automactically switch in a 10dB pad on the channel. Headphone Level ­ controls the level of the headphone output. Power ­ power indicator. DS800 Page 5 Rear Panel Functions 1. MON XLR ­ monitor output normally connected to the monitor desk. The remote controlled pad is controlled from this output by sensing 48V phantom power. FOH XLR ­ Front Of House output normally connected to the front of house desk. Input XLR ­ multifunction input accepts dynamic and condenser microphones and line level inputs. Solo Bus Out XLR ­ used for multiple unit applications, normally connected to the Solo Bus In XLR of the unit above in the rack. When configured in this way the headphones can be inserted into the top unit giving the ability to listen to any channel in the system. Solo Bus In XLR ­ used for multiple unit applications, normally connected to the Solo Bus Out XLR of the unit below in the rack. Mains Inlet ­ combined IEC inlet, fuse and power switch. DS800 Page 6 Block Diagram DS800 Page 7 Grounding The DS800 has a direct connection between Pin 1 of the Input XLR's, Front of House XLR's, Monitor XLR's and the IEC mains inlet earth terminal.
