Introduction
We are very proud of the 2000RB, G-K's most pow-
erful bass amplifier to date, and in many ways, the
culmination of 27 years in the amplification busi-
ness. The 2000RB was designed with you in mind -
to be your personal creative tool, to give you the
ultimate bass response and tone.
many things by talking to bass players like you for
almost three decades. We know you want lots of
headroom and raw power, yet you want your amp to
be dead quiet and free of noise. You need fast
response and clarity. And perhaps most of all, you
want all that great performance night after night, year
after year, from and amp that will never let you
down.
2000RB Features
Power : 500 watts RMS per channel into 2 ohms in
Stereo or Bi-amp Mode, 1000 watts RMS into 4 ohms in
Bridge Mode.
High Current Capacity : 60 amps peak current (5,000
watts of instantaneous power) per channel gives the
2000RB unparalleled transient response with complete
control over the movement of your speakers.
Low Noise Operation : Both preamp and power amp
stages have increased headroom so that noise (hiss) is
barely perceptible.
Three possible operating modes : Bridge Mode, Bi-amp
Mode, and Stereo Mode.
Fault Detection Circuitry : Relays automatically discon-
nect the amplifier from your speakers during power
up/down, or if any unsafe operating conditions occur.
Dual power supplies : Each power amp has its own
power supply. In the unlikely event there is a problem in
one channel, the other will not necessarily be affected.
Fan cooling : Temperature controlled, continuously vari-
able fan speed.
The 2000RB is definitely not just another high power
bass amp. Its High Current Capacity output stages -
capable of delivering instantaneous power of 10,000
watts - are revolutionary. Its relay-activated Fault
Detection Circuitry is state - of - the - art. All the
We've learned
design parameters for the 2000RB are optimized for
response, headroom, and reliability.
Like all G-K bass amps, the 2000RB is user friendly.
It's easy to get the sound you're looking for - in fact,
it's hard to get a bad sound. We took all the same
responsive bass tone G-K amps are known for, and
made it even better. We think you will be very
pleased with your new 2000RB. We are.
