Operating the MDR624
BASIC OPERATIONThe following section explains the basic operation of the MDR624.
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 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 MDR624.
NOTE: SETTING THE INPUT GAIN - When connecting a microphone to channels 1 + 2, it’s a good idea to start with the Gain Control turned all the way down. Set the input fader to the "2 o’clock" 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 MDR624.

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 inrush current at power up, which can sometimes damage loudspeakers.
4.Turn on your power amp or powered monitors and raise the level control to the manufacturers’ recommend- ed operating level.
5.Set the Main Level fader in the MDR624’s master section to the "2 o’clock" 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 peak level meter lights occasionally.
7.You can shape the tone of each channel by adjusting the equalizer controls as desired.
