Preamp:
1. Turn the
Gain
up while playing. Turn up until the
Clip
light flashes and then back off until the light stops flashing. You have
now optimized your signal to noise ratio.
2. If you have a particularly high output instrument it may be necessary to
push the
–10dB
button in to prevent clipping of the input buffer. This
button is located next to the
Input
jack and when pushed in it lowers your
input signal by 10dB.
3. Turn up the
Master
control until you reach the volume you need.
D. Protection Modes
Overcurrent Mode:
In this mode the preamp remains active, but the power amp mutes. The
Status
light does not flash. Power cycle the amp to reset. This may
happen if the load is too low, or if you plug and unplug cabinets while
playing.
Thermal/DC Mode:
In this mode both the preamp and the power amp mute. The
Status
light
flashes. Power cycle the amp to reset. This may happen if the AC line
power is not correct, if the amp is overheating, or if there is risk of
damage to the amp or speakers.
