Controls and Functions

MONO INPUT CHANNEL SECTION

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- nectors. Channels 3/4 and 5/6 are stereo input channels that accept line level signals on standard 1/4" phone connectors for either balanced (TRS – TIP/ RING/SLEEVE) or unbalanced (TS – TIP/SLEEVE) connections. A

detailed explanation of the Input, as well as the Output connectors, can be found in the following section “Input and Output Connections” on page 11 of this manual.

GAIN

The MDR624’s pre-amp stage has a variable GAIN control, which is used to set the sensitivity of the input. Because the input can accept either a mic or line level signal, the GAIN control operates in two ranges based on which input is being used. When a microphone is connected to the input, the range is 5 to 60dB, and when a line is connected, the range is –26 to +26dB. For more infor-

mation on using the GAIN control see the section “CONNECTING MICROPHONES AND INSTRU-

CHANNEL EQUALIZER

 

 

The MDR624 input channels feature a 3-band equalizer allowing you to adjust the

high, mid, and low frequencies independently on each channel. The channel’s fre-

quency 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 up to 15dB,

 

 

and rotating it towards the left will cut the frequency by up to 15dB. The frequency

The AUX section is often used for a monitor mix in a live sound mixing, or for a

which controls the amount of that channel’s signal that is sent to the Aux bus. For
