Controls and Functions
MONO/STEREO INPUT CHANNEL SECTION
The following section details each part of the MDR1064’s MONO INPUT CHANNELS including the GAIN control, LOW CUT switch, 3-BAND EQ, AUX sends, PEAK LED, PAN and LEVEL controls. The input channels one
through six on the MDR1064 feature high quality, discrete transistor pre-amp providing transparency and
extended dynamic range.
1
GAIN
The MDR1064’s pre-amp stage has a variable GAIN control with a range of 5
to 60dB on the MIC input and –26 to +26dB on the LINE input.
2
LOW CUT FILTER
Each of the MDR1064’s first six channels include a LOW CUT (or high pass)
filter which rolls off the low frequencies from 75Hz and below at the rate of
18dB per octave. The LOW CUT filter allows you to remove the lower frequencies that you sometime just don’t want to pick up. For example, when you are
miking a high-hat you only want to capture the frequencies that the hi-hat is
producing. Therefore, by using the LOW CUT filter, you can reduce the
amount of pick-up from the low toms and bass drum that may leak into the hihat mic. You can use the same technique on other instruments like acoustic
guitar, violin, piano and even on vocals. In live sound applications, the LOW
CUT filter is especially useful for removing stage rumble.

CHANNEL EQUALIZER
The MDR1064 input channels feature a 3-band equalizer allowing you to
adjust the high, mid, and low frequencies independently on each channel. The
channel’s frequency response is flat when the knobs are in the "12:00" position. Rotating the knob towards the right will boost the corresponding frequency band by 15dB, and rotating it towards the left will cut the frequency by
15dB. The frequency centers, range of boost or cut, and equalizer type for
each band are as follows:
High: 12KHz +/- 15dB shelving type
Mid: 2.5KHz +/- 15dB peaking type
Low: 80Hz +/- 15dB shelving type
4
AUX 1
3
4
The MDR1064 has two auxiliary sends which can be used for sending signals
to external effects devices or for creating a monitor mix. The AUX1 section is
often used for a monitor mix in a live sound mixing, or for a headphone mix in
a recording application. Each input channel includes an AUX 1 send which
controls the amount of that channel’s signal that is sent to the AUX bus.
5
NOTE: The AUX1 controls are "PRE-FADER SENDS" which means they are
not affected by the FADER level settings of each channel. This allows you to
create a mix for the monitors that is independent of the main LEFT and RIGHT
MIX.
5
AUX 2
The channel’s AUX 2 knob controls the amount of signal that is sent to the AUX 2 bus. The AUX 2 signal
can be sent to an external effects device connected to the AUX 2 OUT jack located in the MASTER SECTION jack field.
6
Controls and Functions
(MONO/STEREO INPUT CHANNEL CONTINUED)
NOTE: The channel’s AUX 2 signal is sent to the AUX 2 bus from a location in the signal path after the
channel’s LEVEL control. This is commonly referred to as a POST FADER send. This means that the
amount of signal that is sent to the AUX 2 bus will be affected not only by the setting of the AUX 2 knob
control, but it will also be affected by the setting of the LEVEL control.
6
BALANCE (Stereo Inputs Only)
The MDR1064’s BALANCE control is used to place or position the
stereo signal into the main Left and Right MIX bus. You can move a
stereo signal’s image to the left or right by setting the BALANCE
control to the left or to the right.
7
6
PAN (Mono Inputs Only)
The MDR1064’s PAN control is used to place or position the mono
signal into the stereo main Left and Right MIX bus. You can create a
stereo image by panning some input signals to the left and others to
the right. The MDR1064’s PAN control is a Power-Pan circuit, which
includes a 3dB dip in the center position. This is desirable since
there’s a 3dB increase in gain when the mono input signal is heard
in both the Left and Right MIX bus.
8
PEAK LED
The MDR1064’s MIC/LINE pre-amp also includes a PEAK LED
which, when illuminated, indicates that the signal is peaking or overloading. To reduce distortion, lower the GAIN control to keep this
LED from staying on.

The MDR1064’s 2 Track section provides the connections for playback and recording for an external device such as a DAT, cassette
recorder, CD or Mini Disk.
12 2TK TO CR
The 2TR TO CR switch is used to assign the 2TR input to the
Control Room output. If you push down the 2TK TO CR button,
signal will be routed into the left and right Control Room output
and will be adjusted by the CR / PHONES control knob.
13 2TK TO MIX
The 2TR TO MIX switch is used to assign the 2TR input to the
MAIN mix bus. If you push the 2TR TO MIX button, the signal
present at the 2 TRACK IN will be routed to the left and right
MAIN output and the level will be controlled by the MAIN
LEVEL knob.
13
Auxiliary Returns
The MDR1064 has two stereo auxiliary returns, which can be
accessed via the two pairs of 1/4-inch phone jacks located on the
master section jack field. The auxiliary returns can be used to connect any stereo line level signal, but they are primarily used to connect the output of external effects processors.

Operating the MDR1064
BASIC OPERATION
The following section explains the basic operation of the MDR1064.
CONNECTING MICROPHONES AND INSTRUMENTS
1. Before connecting mics or instruments, make sure that the power of all your systems components including the
MDR1064 is turned off. Also, make sure that the MAIN LEVEL and PHONES / CR controls are turned all the
way down.
2. Connect the cables to your microphones and instruments, and insert the other end of the cable firmly into the
appropriate input on the MDR1064.
NOTE: SETTING THE INPUT GAIN - When connecting a microphone to channels 1 through 6, it’s a good idea to
start with the Gain Control turned all the way down. Set the input fader to the "0" position and slowly raise the
GAIN control until you see the CLIP LED turn on. Now, back the GAIN control down so that the CLIP LED only
lights for a short time during the loudest input the channel will see.
3. Switch on the power of any peripheral
devices, and then power up the MDR1064.
NOTE: It is important to remember the
Golden Rule of audio … " LAST ON, FIRST
OFF". Translated, this means that when turning on your system, you should always turn
your power amplifiers or powered monitors
on LAST, and when turning your system off,
turn your power amps off FIRST. This helps
avoid any loud pops caused by rush current
at power up, or down, which can sometimes
damage loudspeakers.
4. Turn on your power amp or powered
monitors and raise the level control to the
manufacturers recommended operating
level.
5. Set the MAIN LEVEL control in the
MDR1064’s master section to the "5"
position.
6. While speaking into the mic (or playing
the instrument), adjust the channel
LEVEL control so that the "0" LED of the
MAIN section VU level meter lights occasionally.
7. You can shape the tone of each channel
by adjusting the equalizer controls as desired.
NOTE: You may need to adust the channel LEVEL control to compensate for the slight changes in level after
using the channel equalizer.
12
Operating the MDR1064
SENDING AN INDEPENDENT MIX TO THE MONITOR SPEAKERS
The MDR1064’s AUX1 auxiliary send can be used to feed a separate set of amplifiers and loudspeakers for stage
monitors. This lets you build one mono mix for the amplifiers and monitor speakers facing the musicians, and the
other stereo mix for the amplifiers and speakers facing the audience.
1. Raise the AUX1/MON controls for the channels that you wish to hear from the monitor speakers.
NOTE: The AUX1 controls are "PRE-FADER SENDS" which means they are not affected by the level
settings of each channel. This allows you to create a mix for the monitors that is independent of the main
LEFT and RIGHT MIX.
2. In order to get the most gain from your monitor mix, use an external graphic equalizer (like a Samson S curve
131) to cut out any frequencies that cause feedback.

USING THE CHANNEL INSERT JACKS
To further control your signal, channels 1-6 on the MDR1064 feature an insertion point, or “effects loop”, on one
1/4-inch phone jack, INSERT SEND and RETURN. An insertion point is a patch-point that interrupts the signal,
allowing you to bring that signal outside to
be processed by another device. You can
use these connections to interface an
external signal processor like an equalizer,
compressor, noise gate, reverb and other
audio devices. A common application for
the MDR1064’s insert point is using a compressor.
To send a signal to an external processor,
use a standard 1/4-inch “Y” insert cable to
connect the MDR1064 channel insert point.
Connect the TRS (TIP / RING / SLEEVE)
plug to the channel INSERT point, and
then, connect the 1/4-inch (TIP / SLEEVE),
INSERT SEND plug to the input of the
external processor. The signal is sent back
to the MDR1064, using the 1/4-inch (TIP /
SLEEVE), INSERT RETURN plug connecting to the output of the external processor.
The diagram below shows a typical application for using a compressor (in this
example a Samson C com opti) in the
MDR1064’s insertion point. Also below, is a
diagram showing the wire for the TRS ‘Y”
Insert cable.
13
Operating the MDR1064
USING AN EXTERNAL EFFECT
If you prefer to use an external device for effects processing, you can easily connect the unit using the MDR1064
AUX 2 bus. Follow the simple steps below to interface
your processor:
1. Connect the AUX 2 OUTPUT to the input of the external effect processor.
2. Connect the outputs of the effect processor to the
AUX 2 RETURN located on the MDR1064’s master
section.
3. Set the MAIN LEVEL control to the "5" position.
4. Raise the AUX 2 knobs for the channels to which you
want the external effect to be applied.
5. Set the input level of the external effect so that the
sound is not distorted and so that the effect’s input
meter does not indicate a clipped signal.
6. Use the AUX RETURN 2 control to adjust the level of the effects processed by the external effects device.
PLAYING BACK A CD USING 2T TO MIX
The MDR1064 has a dedicated input for playing back a stereo device such as a CD, Tape or Mini Disk. Below is
a description of how you can play back a CD, Tape or MD using the MDR1064’s 2 TRACK INPUT.
