XM910 Input and Output Connections
CHANNEL 1– 10 MIC and LINE INPUTS
The XM910’s six input channels each have a LINE level, Hi-Z (High Impedance) input and a MIC level, Low-Z
(Low impedance) input. By using the GAIN control, you can connect a variety of signal sources from micro-
phones to line level devices such as synthesizers, drum machines and direct boxes. Both LINE and MIC inputs
are balanced, with MIC inputs compatible with microphones of output impedance 50-600 Ohms and LINE inputs
compatible with line level devices of 600 Ohms.
NOTE
: It is not possible to simultaneously use both the LINE and MIC inputs on the same channel. For each
channel, use only one of the inputs as appropriate for the input source.

LINE - Line Level Input
Use these inputs to connect high impedance microphones, synthesizers and drum machines. The LINE
inputs have a nominal operating level of -40dBV through - 10dBV.

MIC - Microphone Input
Use these inputs to connect Low Impedance microphones and low level signals from direct boxes. The MIC
inputs have a nominal operating level of –50dBV through -20dBV. The MIC inputs also f48V phan-
tom power, allowing you to use condenser microphones. The Phantom Power is switched on/off simultane-
ously for channels 1 through 6.

LINE L / MONO – Left Line Input (Stereo channels only)
Channel 7/8 and 9/10 can accept either stereo or mono inputs. For stereo connections, use the LINE L /
MONO to connect the left channel. If you are using the inputs for a mono line input, use the LINE L / Mono
input only so that the signal feeds both the right and left mix bus. Use these inputs to connect high imped-
ance microphones, synthesizers and drum machines. The LINE inputs have a nominal operating level of -
40dBV through - 10dBV.

LINE R / MIC - Right Line and Microphone Combination Input (Stereo channels
only)
For the right inputs of the stereo channels, the XM910 incorporates a “combo” connector, which can accept
either an XLR or 1/4-inch connector. These stereo inputs includes an extra mic pre which you can use to
connect Low Impedance microphones and low level signals from direct boxes. The MIC inputs also feature
+48V phantom power, allowing you to use condenser microphones. When connecting a stereo signal, use
the 1/4-inch phone jack located in the center of the combo connector to connect the right line input.
