two to three minutes before they are able to pump out full power. Make a habit of
giving your amp plenty of time to get toasty and of flipping the Standby switch for
short breaks.
Avoid storing the amp in damp or dusty rooms to spare jacks, switches and
potentiometers. If you don't use the amp all the time, I recommend that you drape a
covering over it to prevent the intrusion of dust. Even better, keep it in a transport
cover or flight case.
Never use caustic or scouring detergents to clean the amp's housing, front or rear
panels. Use a soft, damp cloth or sponge with diluted soapsuds or a standard brand of
mild dishwashing liquid instead. Never use solvents they can corrode the amp's vinyl
skin and dissolve the front and rear panel labels. Keep liquids well away from the amp,
particularly the interior of the housing.
Make sure air can circulate at the rear and top of the amp to allow for adequate
cooling, which increases component life.
Never operate the amp without an adequate load (a speaker, cabinet or suitable
terminating resistor).
High ambient temperatures place an additional strain on diverse components; so if at
all possible, avoid operating the amp at temperatures far higher than 30°C for longer
periods. Running the amp at mains voltages exceeding the nominal mains input
voltage over longer periods can also shorten component life.
Replace tubes with selected tubes that satisfy ENGL selection criteria to forestall
microphonic properties, undesirable noise and unbalanced power amp signals.
Because power tubes' idle current (bias) must checked and possibly adjusted when
replacing tubes, this is a job best left to experienced and authorized specialists.
In this manual, MIDI programs are called presets and patches.
Though the MIDI standard defines program numbers 000 to 127, almost all MIDI
devices and foot boards indicate and control these programs using a 1-to-128
numbering scheme.
MIDI specifications define 16 channels for sending and receiving MIDI data. The
encoding buttons on the back of the amp determine the MIDI data receiver channel.
MIDI channels: 1 to 16, or OMNI (meaning that all 16 channels receive MIDI data).
This option lets you access the amp's Master Volume Mute function via a suitable MIDI
