The Bi-Amp Advantage
Many players want a little growl in their sound, but due to horn distortion,
it is hard to get good sounding overdrive from passive full-range
systems. The 700RB-II, 1001RB-II, and 2001RB are bi-amped with a
separate 50W amp for driving the horn, so it doesn’t distort when you
drive the amp hard. As a result, you can get all the growl you want from
your lower speakers, while the horn stays clean and articulate. GK
amplifiers have the horn control on the amp front panel, which makes
managing your overall sound that much easier.

2001RB Dual Bi-amp (2 x 500W & 2 x 50W)
It’s the big gun, GK’s candidate for the ultimate stage rig! This unit is
based on the bi-amp system from the 1001RB but with dual 540W woofer
amps bridgeable to 1080W, two 50W horn amps, and two continuously variable
speed fans for cooling. It gets the deep, floor-shaking, warm sound
that powers reggae bands. For rock players, it features a special design
distortion circuit that lets you quickly dial in the perfect growl and drive.
For funk players, its voicing filters and bi-amp controls let you scoop the
mids and add the perfect high-end edge needed for popping. For any style
of music performed on arena stages, the 2001RB is destined to be the premier
amp of choice.
2001RB Distortion Circuit
The secret to the 2001RB’s smooth natural distortion is that the horn amp
is automatically muted when the high gain channel is activated, thus preventing
any raspy distortion from the horns. The horn amps can also be
muted on the low gain channel as needed for certain blues sounds. Such
horn muting is only possible with a bi-amp system, and only the 2001RB
has this circuitry design. Easy on-stage control is provided by a three button
footswitch, which mutes the horns, selects channel A or B, and also
activates the tuning mute.

2001RB Microprocessor
System Manager
An 8-bit microprocessor constantly monitors
the 2001RB system, making sure everything is
running correctly. It waits patiently for you to
push the power switch, and then sends a signal
to your other GK power amps to turn them
on in proper order. Artists such as Flea and
Tom Hamilton use up to five heads, and with
the 2001RB, they only push one switch to fire
up their entire system.
