Input Channel Section

• Balance Input (Mic): Electronically Balanced input accepts standard XLR male connector. +48V phantom power is available on each input Mic socket.
• Line Input: The unbalanced Mic input is provided for the use of an unbalance Mic and is designed to accept an unbalanced high impedance input signal. This use for connection Deck, Turntable Keyboard etc…
• Gain: This is a function which adjusts the input sensitivity of each channel in order to input the constant level of the signal.
• Hi EQ: This control gives you up to 15 dB of boost or cut at 12 kHz and above, and it is also flat at the detente. Use it to add sizzle to cymbals, an an overall sense of transparency or edge to keyboards, vocals, guitar, and bacon frying. Turn it down a little to reduce sibilance, or to hide tape hiss.
• Low EQ: This control gives you up to 15 dB boost or cut at 80 Hz and below. This circuit is flat (no boost or cut) at the center detente position. This frequency represents the punch in bass drums, bass guitar, fat synth patches, and some really serious male singers.
• EFF: Use this control ti set the effect level you want to achieve. The EFF control adjusts the input signal to give you a desired effect. If an extremal source is not in use, the EFF will function through the internal digital delay.
• PAN: The pan control sends continuously variable amounts of the post fader signal to either the left or the right main buses. In the center position, equal amounts of signal are sent to the left and right buses.
• PFL: Used for headphone monitoring of each channel, regardless of the main mix. The PFL (Pre-Fader Listen) function allows the user to listen to the level before fader control; subsequent adjustment of the fader control will not modify the level the control is useful during channel gain adjustment.
• Peak: This is the lamp which indicates the input signal level of this appliance (regardless of output) when GAIN volume is adjusted.
• Channel Fader: This is a function to adjust the volume of signal connection into each channel and adjust the volume of output together with masted fader. Usually operating position is at the "0" mark, providing 4 dB of gain above than point it required.
