Presence

• Controls the amount of higher frequencies of your sound. Turn clockwise to add crispness and bite for a more cutting tone. PRESENCE is a power-stage function and acts independently of the preamp EQ controls.

Resonance

• Controls the amount of lower frequencies in your sound. Turning this control clockwise adds a resonant bass boost, increasing bottom-end. RESONANCE is a power-stage function and acts independently of the preamp EQ controls.

Output

• This three position rocker switch combines STB (standby) and HIGH/ LOW output power functions. The output stage and power control for this amplifier has been designed to deliver the optimum tonal performance at all power levels. The HIGH and LOW output functions allow the user to choose between two configurations of the internal power supply. These two configurations give the choice between two output power levels, but ensure that the output valves behave in the same way for both. This means the amplifier can be put into LOW power mode without compromising on tone.

• Mains power ON/OFF switch.

Mains Input

• Connects the amplifier to the mains electricity supply

Midi In

• Connect your external MIDI device to the MIDI IN socket.
