Microphone Input - Mono Input Channels

Use these inputs to connect Low Impedance microphones and low level signals from direct boxes. The MIC
inputs have a nominal operating level of -62dB through -8dB. The MIC inputs also feature +48V phantom
power, allowing you to use condenser microphones. The Phantom Power switch (located on the MDR10’s
rear panel) enables phantom power on all the microphone inputs when set to the ON position. XLR
Connector pin-out - Pin 1: Ground, Pin 2: Hot (+), Pin 3: Cold (-)

Line Level Input - Mono Input Channels

Use these inputs to connect line level signals from synthesizers, drum machines, effects processors or any
line-level signal. The LINE inputs have a nominal operating level of -40dB through - 10dB. TRS phone
jacks. Connector pin-out - Sleeve: Ground, Tip: Hot (+), Ring: Cold (-)

Stereo/ Dual Mono Input Channels

The MDR10’s channels 7 – 10 can be used for either two stereo inputs or four mono inputs. These chan-
nels feature a combination XLR and 1/4 inch connector, often referred to as a “combie” connector, to han-
dle both the LINE and MIC inputs. The LINE input is located in the center of the combie connector. You can
connect the outputs from devices such as synthesizers, drum machines, effects processors or any line-level
signal. The LINE inputs have a nominal operating level of -27dB through +27dB. The TRS phone jacks
Connector pin-out is; Sleeve: Ground, Tip: Hot (+), Ring: Cold (-). The MDR10’s stereo/dual mono chan-
nels have a utility MIC input located on the combie connector. The utility MIC inputs have a nominal oper-
ating level of -40dB. The MIC inputs also feature +48V phantom power, allowing you to use condenser
microphones. The Phantom Power switch (located on the MDR10’s rear panel) enables phantom power on
all the microphone inputs when set to the ON position. The XLR Connector pin-out is; Pin 1: Ground, Pin 2:
Hot (+), Pin 3: Cold (-).

Left Line/Mic Input

If you want to use channels 7 and 8 as a stereo input you would connect the left side here. When using the
inputs for stereo signals, be sure to set the pan knob all the way to the left to maintain the stereo balance.
Of course, you can connect any mono signals here as well. Channels 9 and 10 are configured the same as
7 and 8.

Right Line/Mic Input

If you want to use channels 7 and 8 as a stereo input you would connect the right side here. When using
the inputs for stereo signals, be sure to set the pan knob all the way to the right to maintain the stereo bal-
ance. Of course, you can connect any mono signals here as well. Channels 9 and 10 are configured the
same as 7 and 8.

MDR10 Input and Output Connections

CHANNEL 1–8 MIC and LINE INPUTS

The MDR10’s input channels 1 - 6 each have an XLR MIC level, Low-Z (Low Impedance) input and a 1/4-inch
LINE level, Hi-Z (High Impedance) input. By using the GAIN control on channels 1- 6, you can connect a variety
of signal sources from microphones and direct boxes to line level devices such as synthesizers and drum
machines. All the LINE and MIC inputs are balanced. The MIC inputs are compatible with microphones with
output impedances of 50~600 Ohms and the LINE inputs are 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 (with the
exception on the stereo input channels). Use only one of the inputs for the appropriate source for each channel.

Following below is a detailed description of the MDR10’s input and output connectors.
