If this lights, rotate the relevant Gain Knob counterclockwise to decrease the input sensitivity. * The Overload Indicators light up when the level of the signal is 6dB lower than the clipping level (=the level where the sound starts being distorted). Gain Knobs The Gain Knobs of each channel adjusts the input gain for mixing the signal with the lowest possible noise and distortion. Clockwise rotation raises the gain (=increasing the volume). 0 Treble Knobs This controls treble sounds. Rotating this clockwise will boost higher frequencies and counterclockwise cut them. o Bass Knob This knob controls bass sounds. Rotating this clockwise will boost lower frequencies and counterclockwise cut them. 0 Effect I Send Knobs These knobs control the level of the signals to be sent to the Effect 1 Send Jack. Clockwise rotation increases the level. For instance, when a reverb unit is connected to the Effect 1 Send/Return Jacks, rotating this knob clockwise will deepen the reverb effect. * The output from the Effect 1 Send is post fader, and therefore changes depending on the positions of the Gain, Treble, Bass and Channel Fader Knobs. 0 Effect 2 Send Knobs These knobs control the level of the signals to be sent to the Effect 2 Send Jack. Clockwise rotation increases the level. For instance, when a reverb unit is connected to the Effect 2 Send/Return Jacks, rotating this knob clockwise will deepen the reverb effect. * The output from the Effect 2 Send is post fader, and therefore changes depending on the positions of the Gain, Treble, Bass and Channel Fader Knobs. 0 Panpot Knobs Each Panpot Knob routes the input signal from an Input Channel to the left and/or right mixing busses. By means of the Panpot Knobs, input signals can be sent exclusively to one mixing bus, or the other, to both mixing busses equally or since the Panpot Knob is continuously variable to both mixing busses in any relative proportion desired. 0 Channel Faders This adjusts the level of the signal sent from each channel. Raising the slider will increase the level, and lowering it will decrease. 7 to 8 position may be ideal for the lowest noise and distortion. 0 Level Meters These indicate the level of the output signals. When "0" of the Level Meter is lit, the output level is -10dBm from the pin jack, and from the standard phone jack is +4dBm with the Output Level Selector set to " + 4", and -10dBm when it is set to "-10". 0 Pilot Lamp When the mixer is turned on, this lamp lights up. © Power Switch This turns on or off the mixer. When it is turned on, the Pilot Lamp lights up. * Turn on or off the mixer with the Master Faders set to zero © Effect 1 Return Knob This knob controls the mixing level of the signal returned to the Effect 1 Return Jacks (L,R) form the external effect (delay, reverb, etc). Clockwise rotation increases the level. Effect 1 Send/Return Jacks, this knob controls the overall volume of the reverb sounds while the Effect 1 Send Knob controls the reverb level of each channel. © Effect 2 Return Knob This knob controls the mixing level of the signal returned to the Effect 2 Return Jacks (L,R) from the external effect (delay, reverb, etc). Clockwise rotation increases the level. (5 0 Headphone Jack Connect stereo headphone to this jack. © Headphone Level Knob This knob controls the volume of the headphone sounds. Rotating this clockwise increases the volume. * The Headphone Level circuits are completely independent from the Master Fader, therefore you can monitor sounds through headphones even the Master Fader is set to zero. © Master Faders (L, R) These sliders control the overall volume of the mixed signals separately for left and right. Raising the slider will increase the volume and lowering it decrease. The optimum level with the lowest noise and distortion is where the red indicators of the Level Meters light occasionally. © Input Jacks These are input jacks for connecting to a mixing device such as microphone, electronic musical instrument, tape deck or CD. © Effect 1 Send Jack This is an output jack for connecting the input jack of an external effect unit (delay, reverb, etc). Through this jack, the signal which has been level-adjusted at the Effect 1 Send Knob of each channel is sent out. © Effect 1 Return Jack (L, R) These are input jacks...
