1. POWER SWITCH
Turns your amplifier on and off.
2. OUTPUT LEVEL
Adjusts the output power level. At high
power the output will be the maximum
available power level. At mid power the
output of the amplifier is set for quieter
performance use and recording (ORI20:
approx. 3W / ORI50: approx. 10W). At
low power the output will be reduced for
home practice (ORI20: approx. 0.5W /
ORI50: approx. 5W).

Note: reducing the power output allows
you to drive the power stage harder at
low volumes. This provides the ability to
benefit from the rich tonal qualities that a
valve power amp can create without the
need to operate at loud volume levels.
3. POWER LIGHT
When the unit is switched on this light
will illuminate.
4. PRESENCE
Adjusts the response of the power
amplifier increasing the higher
frequencies of your sound.

5. MASTER VOLUME
Adjusts output volume. At higher settings,
the power amplifier can be overdriven,
giving a classic overdrive sound.
EQ Settings: your Origin amplifier has
4 equalisation controls (presence, treble,
middle and bass) plus an amplifier channel
voice control (tilt). All these controls allow
you to adjust the frequency and voicing.
Each control is highly effective and
interactive.
