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.
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.
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 hi-hat 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
AUX 1
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.
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.
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.
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.
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.
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.
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.
CHANNEL LEVEL
The MDR1064's LEVEL control knobs are used to adjust the overall channel volume.
Controls and Functions
MASTER SECTION
MAIN LEVEL
The master MAIN control is the overall volume control for the left and right mix bus. These line level signals are output from the MAIN MIX jacks.
PHONES / CR
The PHONES / CR control is used to set the level sent to the control room outputs, and also to the headphone jack.
2 TRACK INPUT AND OUTPUT
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.
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.
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.
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.
AUX RET 1
This adjusts the amount of signal that is sent from the AUX 1 RET jacks to the MAIN bus.
Controls and Functions
MASTER SECTION (continued)
AUX RET 2
The AUX RETURN 2 adjusts the level of the signal present at the AUX 2 RET jacks. This signal is summed, or mixed in to the main L/R MIX bus.
TO AUX 1
This routes the signal that is present on the AUX 2 RETURN jacks to AUX 1 so that the effects can be heard in the monitor mix.
POWER LED
The Power LED lights up to indicate that the main POWER switch (located on the rear panel) is on.
Phantom Power LED
This LED illuminates indicating that the 48 volt phantom power is applied to the microphone pre-amps enabling use with condenser microphones. The +48V LED will light up when the Phantom Power switch (located on the rear panel) is switched to the ON position.
Output Level Meter
The OUTPUT LEVEL METER allows you to monitor the level of the signal which is being sent to the MIX OUT jacks.
NOTE: To avoid distortion, adjust the Main Level control so that the 0 indicator LED lights occasionally.
MDR1064 Input and Output Connections
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.

Operating the MDR1064
BASIC OPERATION
The following section explains the basic operation of the MDR1064.
CONNECTING MICROPHONES AND INSTRUMENTS
-
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.
-
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.
- 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.
-
Turn on your power amp or powered monitors and raise the level control to the manufacturers recommended operating level.
-
Set the MAIN LEVEL control in the MDR1064's master section to the "5" position.
-
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.
-
You can shape the tone of each channel by adjusting the equalizer controls as desired.
NOTE: You may need to adjust the channel LEVEL control to compensate for the slight changes in level after using the channel equalizer.
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.
- 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.
- 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.
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:
- Connect the AUX 2 OUTPUT to the input of the external effect processor.
- Connect the outputs of the effect processor to the AUX 2 RETURN located on the MDR1064's master section.
- Set the MAIN LEVEL control to the "5" position.
- Raise the AUX 2 knobs for the channels to which you want the external effect to be applied.
- 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.
- Use the AUX RETURN 2 control to adjust the level of the effects processed by the external effects device.
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.
- Turn the MAIN level control all the way down.
- Press the 2TK TO MIX button down.
- Adjust the MAIN LEVEL control in the master section to the "5" position.
- Start playback on the CD, Tape or MD player, and use the MAIN LEVEL control to set the desired level.
You can record the audio from the MDR1064's mixer section including the MIC, LINE, 2T IN and AUX inputs to a Cassette deck, MD, DAT or any other type of recorder using the 2T OUT outputs. Simply connect the MDR1064's 2 TRACK OUT to the input jacks of the recorder as shown in the diagram on the right and follow the steps below.
- Adjust the MAIN LEVEL control in the master section to the "5" position.
- Set a clean signal using the recorder's input level controls and meters.
- Press RECORD.
- Play back using as described in the previous section "PLAYING BACK A CD USING 2T TO MIX".
