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:
