Phoenix Audio DRS-8 Mk2 - 8 Channel Class A Microphone Pre-Amplifier - Manual (Page 4)

Input Connectors: The Input connectors are XLR/1/4” Jack “combo” sockets. These
will accept XLR or 1/4” Stereo or Mono Jack plugs. Either type of input connector can
be used, at any time, in any channel. Special attention should be paid to the +48V
switch position (see +48V switch) when using LINE level inputs.
Output Connectors: The output connectors are standard 3 Pin XLR connectors. These
outputs are transformer-coupled balanced outputs.
Monitor Connector: The monitor connector is a 25 pin “D-sub” connector. This is
wired “Tascam” standard. The output of all 8 channels, are available on the connector.
These outputs can be used in addition with the main Output XLR connectors and can
be sent to outboard equipment, patch bays, or monitoring systems. The output levels
are controlled by the Output level control on each channel. The output level will
always be -8dBu lower than the main Output XLR's.
