1 - HI/MID/LOW EQUALIZER: Powerful 15dB boost or cut allows you to tailor the sound of each individual channel so the instrument blends more naturally in the mix. The HIGH EQ is a 12 kHz shelving type to add or cut "sizzle". MID has a center frequency of 1.2 kHz, approximately in the vocal range. The LOW EQ is an 80 Hz shelving type, around the kick-drum frequency.

2 - EFFECT SEND (REV/FX): Controls the level of the signal sent to the internal digital effects and the FX SEND bus. This control comes after the LEVEL control, so the signal sent to internal or external effects will also be affected by changes in the LEVEL setting.

3 - MONITOR: Controls the level of the signal sent to the MONITOR bus and MONITOR OUT jack. This control is independent of the LEVEL control and is not affected by it. This means you can create a completely separate mix for on-stage monitoring.

4 - LEVEL: Controls the level of the input signal sent to the MAIN bus. Generally used for creating the mix sent to the audience.

5 - LINE/MIC INPUTS (Channels 1-4): Use the LINE input for instruments that provide line level signals such as synthesizers or drum machines. Use the MIC input for low level signal sources such as microphones. +48V phantom power is available for use with condenser microphones. You can also use both LINE and MIC inputs simultaneously for each channel.

6 - LINE/MIC INPUTS (Channels 5-6): LINE input functions as channels 1-4. LINE/MIC input accepts both XLR and phone jacks. You can connect a stereo signal to both phone jacks (LINE and MIC/LINE) for summing to a mono signal.

7 - DIGITAL EFFECTS: A selection of 16 powerful digital reverb and delay effects to add extra ambiance to your music. A foot switch may be used to turn the digital effects on/off for dramatic sonic changes while playing, and the green indicator lights when the effects are on.

8 - PHANTOM: Turns +48V phantom power on/off for condenser microphones connected to the MIC inputs of channels 1-6. The green indicator lights when phantom power is on.

9 - FX SEND: Controls the combined level of signals sent from the FX SEND bus to an external effects processor connected to the FX SEND jack. This control has no effect on the signal level sent to the built-in digital effects.

10 - TAPE/AUX IN LEVEL: Lets you adjust the level sent to the MAIN bus from the TAPE IN/AUX IN connectors.

11 - MAIN/BRIDGED SECTION: Graphic equalizer +/-12dB 7-band graphic equalizer adjusts the EQ curve of the MAIN bus signal sent to the AMP 1 A/B speakers. Use it to compensate for poor acoustics in a hall or to prevent feedback. REV/FX: Adjusts the built-in digital effects level sent to the MAIN bus. Set to "0" (or use a foot switch) to turn effects off. LEVEL: Controls the output level of the MAIN bus signal sent to the MAIN OUT jack and the internal AMP 1. Peak level indicators: Provides visual indication of the signal level at the MAIN OUT jack and AMP 1 input.

12 - MONITOR SECTION: Graphic equalizer +/-12dB 7-band graphic equalizer adjusts the EQ curve of the MONITOR bus signal sent to the AMP 2 A/B speakers. Use it to compensate for poor acoustics in a hall or on stage, or to prevent feedback. REV/FX: Adjusts the built-in digital effects level sent to the MONITOR bus. Set to "0" (or use a foot switch) to turn effects off. LEVEL: Controls the output level of the MONITOR bus signal sent to the MONITOR OUT jack and the internal AMP 2. Peak level indicators: Provides visual indication of the signal level at the MONITOR OUT jack and AMP 2 input.

13 - MODE: Allows you to select signal routing to the internal amplifiers. MAIN TO AMP 1/MONITOR TO AMP: Gives you a 200 watts mono MAIN (audience) mix and a separate 200 watts mono MONITOR (on-stage) mix, without the need for any external amplifiers. MAIN TO AMP 1 & 2: Allows you to send a 200 watts per channel, 2- or 4-speaker mono mix to the audience. You can also have a separate on-stage mix by connecting another amplifier (or mixer) to the MONITOR OUT jack on the front panel. BRIDGED: Combines the output power of both amplifiers to achieve a single mono BRIDGED output capable of providing up to 400W RMS. Again, for on-stage monitoring, connect a separate amp to the front panel MONITOR OUT jack.

14 - FX FOOT SWITCH: Connect a foot switch here for remote on/off control of the built-in digital effects.

15 - FX SEND: Signal from this jack may be connected to the input of an effects processor.

16 - TAPE: IN: Input to the MAIN bus from a cassette or tape deck, CD or MD player, DJ turntable setup, or other audio source. OUT: Tape level output of the MAIN bus signal, handy for recording performances.

17 - AUX IN: Connect an external effects unit here, to save using one of the input channels.

18 - MAIN OUT & MONITOR OUT: Signals from these jacks may be connected to the input of external power amplifiers. MAIN OUT is the audience mix, MONITOR OUT is the on-stage mix.

19 - AMP 1 IN/AMP 2 IN: A line level signal may be connected to either of these jacks for direct input to the internal power amplifiers.

20 - SPEAKERS: Use the front panel MODE switch to select the output mode of these speaker jacks. The built-in power amps can be used in an independent 200 W + 200 W configuration, or bridged to give a single channel output of 400 W. One 4 ohm or two 8 ohm speakers can be connected to each amplifier, or a single 8 ohm speaker can be connected to the bridged output.
