1. Mono input jack:
   [MIC/LINE]: Accepts both XLR connectors, 6.35mm (1/4”) balanced TRS phone and unbalanced TS phone connectors. Connect microphones and/or instruments you intend to use.

2. TRACK] stereo jacks
   The stereo input jacks (RCA) are designed to accept a 2-track recorder (.g. DAT recorder), or they can be used as stereo line input.
   If you connect the output of a hi-fi amplifier (with a source selection switch) to the CD/TAPE INPUT, you can easily listen to additional sources (e.g. cassette recorder, MD player, sound card, etc.)
   The stereo output jacks (RCA) are parallel to the MAIN OUT and carry the main mix signal (unbalanced). Connect these jacks to the inputs of your recording device. The final output level can be adjusted via the [2TR/MP3] fader.

3. [INSERT] jack
   “This jack accepts an impedance-balanced TRS phone-type connector (stereo phone plug = signal output + return input). Insert points enable to process channel signals with dynamic processors or equalizers. They are sourced pre- fader, pre-EQ, and pre-aux send.

4. [PAD) switch
   It reduces the input gain to prevent loud input sources from overloading the preamp and clipping.
   When this switch is tured on ( ), the input signal from the [MIC/LINE] jack (mono input channel) is attenuated by 26dB. Turn this switch off ( ) if you’ve connected a microphone or other device with a low input level to the channel. Tun it on ( ) if you’ve connected a line-level device. “NOTE: To prevent possible noise when operating switches, tur it off of a channel before operating other switches.

5. [LOW CUT] switch
   This switch eliminates unwanted, low-frequency signal components under 100Hz for a smoother, cleaner mix. Turning this switch on will apply the filter to the mono input channel.

6. [GAIN] switch
   For adjusting the gain of the input signal. Mono input channels have a [PAD] switch that lets you change the range of this control.

7. Equalizer ([HIGH)IMIDY[LOW])
   The equalizer shapes the high, mid, and low audio frequencies. Turning the knob to the right amplifies (boosts) the corresponding frequency band while turning it o the left attenuates (cuts) the band. Setting the knob to the middle position produces a flat response in the corresponding band. The upper knob sets the variable mid frequency, while the lower knob sets the amount of attenuation or boost (counterclockwise/ clockwise) for the range.
