6 Controls and Functions The following section details each part of the MDR624’s input channels including the GAIN control, 3-BAND EQ, AUX send, PAN, BALANCE and LEVEL controls. The input channels One and Two on the MDR624 feature high quality, discrete transistor pre-amps providing transparency and extended dynamic range on standard XLR con- nec[...]

BALANCE (Stereo Inputs Only) The MDR624’s BALANCE control is used to place or position a mono input into the stereo main Left and Right MIX bus. For a stereo input, the balance control is used to center the sound between the Left and Right Mix bus. You can create a stereo image by panning some input signals to the left and others to the right. PA[...]

MAIN LEVEL The master MAIN control is the overall volume control for the left and right mix bus. The MAIN LEVEL affects both the Control ROOM signal which is output to the speakers and the line level signal which is output from the MIX OUT jacks. CR / PHONES The C/ROOM + PHONES control is used to set the level sent to the control room outputs, and [...]

POWER LED The Power LED lights up to indicate that the main POWER switch (located on the rear panel) is on. - Phantom P ower LED This LED illuminates indicating that the 48 volt phantom power is applied to the microphone pre-amps enabling use with condenser micro- phones. The +48V LED will light up when the Phantom Power switch (located on the rear[...]

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 –50dB through -20dB. The MIC inputs also feature +48V phantom power, allowing you to use condenser microphones. The Phantom Power switch (located on the MDR624’s r[...]

AUX Send The signal present at the AUX output is sent from the AUX bus, which is fed from the AUX send on the input channels. The AUX output can be used as the MONITOR MIX bus in a live sound situation by con- necting the output to a power amp and monitor speak- er. AUX RETURN LEFT/RIGHT The AUX RETURN LEFT/RIGHT are stereo inputs that are generall[...]

12 Operating the MDR624 BASIC OPERATION The following section explains the basic operation of the MDR624. CONNECTING MICROPHONES AND INSTRUMENTS 1. Before connecting mics or instruments, make sure that the power of all your sys- tems components, including the MDR624, are turned off. Also, make sure that the Left and Right MIX faders are turned all [...]

13 Operating the MDR624 USING AN EXTERNAL EFFECT If you want to use an external device for effects processing, you can easily connect the unit using the MDR624 AUX bus. Follow the simple steps below to interface your processor: 1. Set the L/R mix faders to the "2 o’clock" position. 2. Raise the AUX knobs for the channels to which you wa[...]
