INITIAL SET UP

INITIAL SETUP
Improper input channel volume setting and performers� microphone / speaker setting often produce feedback. The following procedure is very important, even if you don�t like to read manuals, please read this section. After you connected the system, you are ready for the initial set up for every input channel; matching every input gain to the signal source is crucial, every little detail will affect the final output of the mixer. Basically, the input sensitivity adjustment, channel fader, and output fader all could be a major factor. You should try to set only as much microphone gain as required to achieve good balance between signals. If the input gain is set too low, you will not get enough gain on the faders to push the signal up to an adequate level. If it is set too high, the channel fader will need to be pulled down for compensation, leaving greater risk of feedback because even small fader movements have very significant effect on output level. Please use the following set up procedure: l Turn all faders and gain controls all the way down to the minimum level before turning on the power. l Set EQ control at �0� position. l Condenser microphone should be connected before turning on the +48V phantom power. l Set power amplifier level to around 2 o�clock. l Set the CTRL RM Level and Headphone level to around 12 o�clock. l If you want to hear what you�re doing, be sure to plug your headphones into the phone output socket, or hook up your control room amplifier system to the CTRL RM output. l Press the PFL button, then related LED should light. l Set PAN control at desired position. l Apply a typical performance level signal, monitor the level on the level meter. l Adjust the input gain until the signal level lingers around the �0� number at master level meter, with occasional peaks to the top red LED at maximum source level. This allows enough headroom

to accommodate peaks and the maximum level for normal operation; you can listen to them through headphones. l Gain control adjustment for microphone input depends on the kind of the microphone you use. In general, turn the gain clockwise to somewhere in between 2 to 3 o�clock. Then have a singer to perform as he would in front of an audience while you do sound check. Don�t not whisper, if he does not sing at a normal level you might set the gain level too high causing sound to distort and lose definition, some times even produce feedback. l Repeat the same procedure for every other channel, when more channels are added to the setup, the master level meters may move up to the peak section, adjust the overall level using the MAIN L/R fader when necessary. l Avoid using equalizer excessively since it may increase the chance of producing feedback and often change too much of the original sound. l Improper volume setting of stage monitors often causes feedback. As long as the performer can hear what�s being reproduced, the volume doesn�t need to be set too high. Do not point microphone directly to a speaker. Equalization is necessary for using these monitoring systems. l Other ways for artists to monitor include headphones and speakers on stands.
