GK Philosophy

I have never seen the point in doing things the way
others have done them. I also have not been very
interested in following the latest fad. I am a
Stanford educated engineer who worked his way
through school as a musician. Like all musicians, I
have lugged amplifiers up stairways and into car
trunks, always wondering why these things had to
be so heavy, bulky, and hard to handle.
As I am the principal innovator at GK, our products

Introduction

reflect my attitudes and life experiences. I don’t model
my designs after other manufacturer’s products (as
some of our competitors are proud of reciting).
Instead, I believe new and old problems are best solved
with new solutions. Having taken our own path,
products enjoy a unique, unmatched sound, allowing
the artist using them every opportunity to make an
original statement.
Having supported my products for over thirty years, I
have learned from the story they tell.
is a reflection of that story, and has a commitment to
support that legacy. Just as the products I created
thirty years ago are still telling their story, the products
we create today will be talking to us tomorrow.

Safety Information

2001RB & 2001RBP

Verify Line Voltage and Amperage Before
Use:

Your new 2001RB or RBP amp has been factory
configured for use with:

.
.
.

.

Connecting the amplifier to a line with specifications
other than indicated above can create a safety and
fire hazard, and may damage the amplifier. If you
have any questions about the voltage requirements
for your specific model, or about the line voltage in
your area, contact your dealer before plugging the
unit into a wall outlet.

Verify AC Circuit Capacity Before Use:

The high power output of your amplifier may require
heavy current draw under Full-Load conditions. To
insure proper performance and avoid potential safety
hazards, we recommend connection to line circuits
with amperage specified “as above”. Connecting
multiple amplifiers to the same circuit, or connecting
the amplifier to the same circuit used by other heavy­power devices, such as high-wattage lights, may cause
circuit breakers to trip. It is always a good idea to
avoid using any audio equipment on the same AC
circuit as equipment with motors, such as air condi­tioners or refrigerators. This will lessen to possibility
of power variation and electrical start-up noise
affecting your sound.

120 Volt/60Hz 15 Amp circuit for USA &
Canada.
230 Volt/50Hz 10 Amp circuit for Europe
& Australia.
100 Volt/50Hz 15 Amp circuit for Japan.
Proper AC circuit for all other countries.

Do Not Use Extension Cords:

To avoid safety hazards, use only the power cord
supplied with your unit. If a replacement cord is
used, make certain that it is of consistent quality and
gauge as the original. We do not recommend using
extension cords with this product. As with all electri­cal devices, do not run power cords under rugs or
carpets or place heavy objects on them. Damaged
power cords should be replaced immediately with
cords meeting factory specifications.

Handle The AC Power Cord Gently:

When disconnecting the power cord from an AC
outlet, always pull the plug, never pull the cord. If
you do not intend to use the amplifier for a consider­able length of time, disconnect the plug from the AC
outlet.

Do Not Open The Amplifier Enclosure:

There are no user-serviceable components inside this
product. Opening the amplifier enclosure may
present a shock hazard, and modification to the
product will void your warranty. If liquid enters the
unit, or any metal object such as a paper clip, wire, or
staple accidentally falls inside the enclosure, discon­nect the unit from the AC power source immediately
and consult an authorized service station.

Unpacking:

The carton and packing materials used in shipping
your new amplifier were specially designed to cushion
it from the shocks and vibration that occur during
transport. We suggest that you save the carton and
packing materials for use in shipping, in the event
you move, or the amplifier needs repair.

2001RB & 2001RBP

Quick Start

The 2001RB is designed to be simple to operate.
All controls have a well defined purpose and are well
behaved. These directions will take you through the
basics and give you a good start for setting up your
sound.

1. Plug it in:

Set the power switch to Off and connect the supplied
power cord, from the amplifier AC receptacle, to an AC
power outlet of proper voltage and power rating (see

Quick Start

safety information on page 5 for details).

2. Connect your cabinets:

Connect your speaker cabinet(s) to the LEFT or
RIGHT 1/4” speaker jacks or Speakon outputs if
using our RBH series cabinets. Be sure not to exceed
the maximum recommended speaker loads below.

Maximum Recommended Speaker Loads:

Two 4 ohm or four 8 ohm cabinets per side in dual
mono mode. One or two 8 ohm horns per side on the
50W amp. To connect other manufacturer’s cabinets,
use the LEFT or RIGHT 1/4” jack speaker outputs
only.

If you are using an RBH Series cabinet, use the
supplied 4 conductor Speakon cable to connect to the
“Speakon” outputs on the rear panel of the amplifier.
In addition, set the switch on the RBH cabinet to Bi­Amp.

For more information on Bridged mode and Bi-Amped
mode, see pages 10-11.

Caution:

Do not connect the Speakon cables labeled “Bridge
Mode” to the 2001RB. This may result in damage to
the amplifier.

3. Initial front panel control settings:

Set all EQ controls and the Boost control to 12
o’clock. The Voicing Filters should be turned all the
way down to get a flat response. Set the Level and
Master Volumes at 0. If you have a five string bass,
push the button marked String Bass in. Make sure the
Level A/B button is out, so you are in the clean
channel.

4. Plug in your bass:

Using an instrument cable, connect your bass to the
Input jack and press the power switch on. If you have
active tone controls on your bass, turn all of the
controls to the middle or flat position and turn the
volume all the way up. If you have conventional,
passive tone controls, turn all tone and volume
controls all the way up.

5. Level and Master Volume settings:

Set the Master Volume to 12 o’clock. Turn the Level-A
volume up as you play. Try not to turn it past 1
o’clock if you have a bass with active tone controls
unless you want an overdrive effect. If the yellow clip
light turns on, press the -10db button in. If it is still
on, try turning the volume down on your bass.

At this point:

You should be hearing your bass quite well. You can
use the Volume and Woofer-Master to achieve a

comfortable sound level.

more volume, turn up the Woofer-Master control first.

Remember:
