PGA-04 Speaker Simulator
The PGA-04 ADIG-LB - Advanced Direct Injection for
Guitar-Load Box is the successor to our legendary speaker simulator,
which has conquered recording studios world wide and is used by
such renowned artists as Keith Richards/Rolling Stones, Alex Lifeson/Rush,
Warren Cucurollo/Duran Duran, as well as Eddie Van Halen and Def
Leppard, only to name a few...
The PGA-04 is a single channel speaker simulator with a built-in
8ohm load box in a single space rack mount unit. It is designed
for using your favorite amp without a speaker cabinet. You can
record or use it live for in-ear monitors. The built-in 8ohm load
box replaces the cabinet while letting your amp react as if it
were pushing speakers. You get the same effect.
This is a passive unit requiring no batteries or external power.
It operates from the power generated by the speaker output of your
It has a FILTER section for cabinet simulation which has a volume
, low and high frequency control. It also has a color switch
for BROWN, a dark mid-rangy tone, and LITE, for a more open
and airy tone. The FULL RANGE section has a volume control
and a HI-CUT switch. This is a direct guitar signal that is
not filtered or dependant on the tone controls except for the
The unit has 2 unbalanced 1/4in outputs and one XLR balanced output.
You can use any or all of these at any time. Just plug a speaker
cable from the speaker output of your amp into the speaker input
of the PGA-04. The internal load box will act as a speaker cabinet.
Then plug an XLR cable from the PGA-04 to a console or stage box.
The 1/4in outputs can be connected to an FX rack or direct to a
You can also use a speaker cabinet with the unit by plugging a
cabinet into the 'THRU' jack. This will bypass the load box so
your amp doesn't even know it's there, but you have a live sound
plus all the tonal options of the PGA-04 routed to your engineer.
Try it. You'll love it. And so will your engineer.
