To reduce the hazard of electrical shock, do not remove cover or back. Please refer all servicing to qualified personnel. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

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 connectors. 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. 1 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 infor30 mation on using the GAIN control see the section "CONNECTING MICROPHONES AND INSTRUGAIN MENTS" on page 12 of this manual. 1 5 -26 +26 60 G 2 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 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 up to 15dB, and rotating it towards the left will cut the frequency by up to 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 0 5 5 HF 12K 10 10 15 15 0 2 10 5 5 2. 5K 10 MF 15 15 0 3 AUX SEND 10 5 5 80Hz 10 LF The AUX section is often used for a monitor mix in a live sound mixing, or for a headphone mix in a recording application. [. . . ] You can shape the tone of each channel by adjusting the equalizer controls as desired. 12 Operating the MDR624 SENDING AN INDEPENDENT MIX TO THE MONITOR SPEAKERS The MDR624's AUX send can be used to feed a separate set of amplifiers and loudspeakers for stage monitors. This lets you build one stereo mix for the amplifiers and speakers facing the audience and the other mono mix for the amplifiers and monitor speakers facing the musicians. Raise the AUX controls for the channels that you wish to hear from the monitor speakers. NOTE: The AUX controls are "PRE-FADER SENDS" which means they are not affected by the FADER level settings of each channel. [. . . ]
