CHANNEL 1 – 6 MIC and LINE INPUTS
The MDR1064’s channel 1 through 6 mono inputs each have a 1/4-inch connector for line level signals and XLR
connectors for the MIC signals. Channels 7/8 and 9/10 stereo inputs each have 1/4-inch connectors for line level
inputs. By using the GAIN control on channels 1 through 6, you can connect a variety of signal sources from
microphones 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. Following below is a detailed description of the
MDR1064’s input and output connectors.
NOTE:
It is not possible to simultaneously use both the LINE and MIC inputs on the same channel. Use only one
of the inputs for the appropriate source on each channel.

Microphone Input - Mono Input Channels
Use these inputs to connect Low Impedance micro-
phones and low level signals from direct boxes. The MIC
inputs have a nominal operating level of –50dBu through
-20dBu. The MIC inputs also feature +48V phantom
power, allowing you to use condenser microphones. The
Phantom Power switch (located on the MDR1064’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 synthesizers, drum
machines, effects processors or any line-level signal.
The LINE inputs have a nominal operating level of -
40dBV through - 10dBV. TRS phone jacks Connector
pin-out - Sleeve: Ground, Tip: Hot (+), Ring: Cold (-)
Insert Point Jack - Mono Input Channels
The MDR1064’s mono input channels feature a 1/4-inch
TRS INSERT jack providing a patch point to connect an
external processor. You can use these connections to
interface an external signal processor like an equalizer,
compressor, noise gate, reverb and other audio devices.
For more information on the channel INSERT points, see
the section, “Using the Channel Insert Jacks” on page 13
of this manual.
Line Level Input - Stereo Input Channels
You can connect the outputs from stereo devices such as
synthesizers, drum machines, effects processors or any
stereo line-level signal. Use the LEFT input when con-
necting a mono input signal to the Stereo Input channels.
The LINE inputs have a nominal operating level of -
40dBV through - 10dBV. TRS phone jacks Connector pin-
out - Sleeve: Ground, Tip: Hot (+), Ring: Cold (-)

MASTER SECTION INPUT AND OUTPUT JACKS
The MDR1064 features several output connectors allowing you to interface a variety of external devices. A
stereo recording device, such as a cassette recorder, can be connected to the 2 Track jacks, and power ampli-
fiers or powered monitors can be connected to the CONTROL ROOM and MAIN output jacks.
