brought on by power tube defects/failure and ensure the amp does not shut

operates at a perceptibly reduced output level. LEDs indicate which channel's
tube fuse has triggered. In addition, a thermal overload protector powers the
amp down if the it overheats because of a problem with the fan.

craftsmanship, impeccable finishing and highest quality components. Bear in mind,

A tip from the designer:

2 VOLUME LEFT A

You'll find an ancillary pamphlet accompanying this owner's manual entitled
Instructions for the Prevention of Fire, Electrical Shock and Injury. Be sure to read it
before you plug in and power up the Power Amp!

This button's setting determines the input sensitivity for both the left and right
channels of the power amp;

The 810 Power Amp offers quite a lot of gain, so you can plug a guitar straight into
it. If you set the Volume controls to 12 o'clock or higher and select High Gain mode
by pressing the Gain P.A. button (1), you will be able to push the power amp into
the overdrive zone, with plenty of saturation for certain styles such as snarling rock
riffs.
Use the Presence and Depth tone controls in combination with the Volume A and B
knobs to dial in four different sounds on the power amp and then access them via
footswitch. For example, you could configure a clean sound for single-coil pickups
by setting the Volume knobs (2 & 5) to around 12 o'clock, (7) in the 1-
to-4 o'clock range, and (8) to somewhere between 11 and 3 o'clock. You
can coax vintage sounds with that typical EL84 flavor and moderate overdrive out
of the amp by setting (3 & 6) to somewhere between 1 and 3 o'clock in
combination with (10) and (11) set anywhere from 8 to 12
o'clock. If you add the guitar's volume knob to the sonic equation, you get a vast
spectrum of fine tonal distinctions. If you want to hit the input section a little
harder to strike a more aggressive note, set the L & R channels' Volume controls
between 3 and 5 o'clock. In combination with humbuckers, this should give you
enough juice for a lower gain lead sound. Be sure to dial back the activated Depth
knob to a position lower than 10 o'clock so the bottom end doesn't get muddy. If
you're aiming for a pristine clean sound with humbucking pickups, you will have to
back off the Volume knobs to a relatively low setting or select Low Gain mode on
the Gain P.A. This is done by ensuring the button is not pressed in.

Benefits and practical application of Sound Set A/B switching:
This unique feature lets you combine various preamp configurations with the two
power amp EQ setups and , easily and conveniently. You
can tweak the power amp to shape the tone in different ways using the two
Sound Set EQs, thereby considerably extending your sonic spectrum.
The two power amp EQs let you sculpt different basic sounds, say clean and lead,
with great precision, so you can dial in exactly the sound you wish to hear. Let's
look at a typical example using a multi-channel preamp (that is, a dual clean/lead-
channel device):

:
Presence B knob setting between 9 and 1 o'clock;
Depth B knob setting somewhere in the 12-to-3 o'clock range;

Activate the preamp's clean channel and : Lots of high end and a
moderate amount of low end yield crisp clean tone. Activate for the
preamp's lead channel (that is, overdriven preamp). Reduced treble and plenty of
low-end punch yield warm, assertive lead tone.

This LED lights up as soon as the amp's left channel is activated via the Standby
switch (14). This tells you the left channel is ready to go. A flashing LED indicates
that a power tube fuse has triggered because of an overload or a defect in either
the V4 or V5 power tubes. See the tube map on page 13 for the positions of the
two tubes and their fuses in the chassis.

This LED lights up as soon as the amp's right channel is activated via the Standby
button (15). This tells you the right channel is ready to go. A flashing LED indicates
that a power tube fuse has tripped because of an overload or a defect in either the
V6 or V7 power tubes. See the tube map on page 13 for the positions of the two
tubes and their fuses in the chassis.

Left channel standby switch. Use this switch to silence ("0" indicated) the left
channel when you take a longer break. The power amp's tubes stay nice and
toasty, and the channel is ready to roll immediately when you ramp it back up to
full power. If you wish to use the right channel only, you must deactivate the left
channel with the Standby switch (14).

Right channel standby switch. Use this switch to silence ("0" indicated) the right
channel when you take a longer break. The power amp's tubes stay nice and

full power. If you wish to use the left channel only, you must deactivate the right
channel with the Standby switch (15).
