AVT150/AVT150H & AVT275 Front Panel Features
23 DFX Mix Controls
(Clean FX & Overdrive FX)
These determine the level of the internal
effects selected by the pair of Program controls
(25). The top DFX Mix control works on the
two OD channels while the bottom one works
on the Acoustic Simulator and Clean channels.
In general you will find that the modulation
effects (e.g. Chorus, Flange) require more level
than the reverbs and delays. As always, let
your ears decide what is right!
24 Adjust Controls
(Clean FX & Overdrive FX)
For each of the 16 selectable DFX a
particular parameter is adjustable. For
example, when a Reverb is chosen, the decay
(how long the reverb will be heard before it
fades away) is adjustable via this control. The
‘Program/Adjust’ table (26) on the front panel of
your amp lists what the Adjust control does for
each of the 16 programs. As was the case with
the DFX Mix controls, the top Adjust control
works for the two OD channels and the bottom
one for the Clean & Acoustic Simulator
channels.
25 Program
(Clean FX & Overdrive FX)
These select each one of the 16 on board
digital effects - the top Program control works
on the two OD channels and the bottom control
works for the Clean and Acoustic Simulator
Channels. The DFX available include single
effects such as Reverb (9 types), Delay or
Chorus and also multi-FX such as
Chorus/Delay/Room. To add further to the
flexibility of these two DFX sections, they can
be switched on and off via the sturdy, LED foot-
controller which comes supplied with each amp.
26 Digital FX Program/
Adjust Table
This lists the 16 programs selectable via
the Program control (25) and also indicates
which parameter the Adjust control (24)
modifies for each one. For added convenience,
this table is shown below.
27 Power Switch
Wait for it...yes, this switches the amp on
and off! When the amp is on the power switch
is illuminated and vice-versa. Advanced power
amplifier muting circuitry provides anti-thump
protection on power up and down.
Important Note:
As is the case with an all-
valve amplifier, there will be no signal heard
until the amp's ECC83 preamp valve warms-up
and starts to pass signal. This can take up to
15 seconds so don't panic!
