Always Listening
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 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.
ment 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.
We’ll be listening,
Gallien-Krueger
is a reflection of that story, and has a commit-

All
RBH
cabinets utilize a unique crossover system, providing easy setup for BiAmp or Normal (full range) operation. If you have a
the
700RB
you can easily gain the benefits of true Bi-Amp operation. Bi-Amp
systems use separate power amplifiers for the horn and woofer, with an
electronic crossover that separates the sound into highs (for the horn), and lows
(for the woofer). This arrangement does two things for the sound:
1) The crossover being electronic, can be far superior to the passive crossover
found in full range systems providing a more seamless, accurate sound.
2) With separate power amps for the horn and woofer, the artist can overdrive
the woofer power amp (creating the desired growl) while keeping the horn
amplifier clean and undistorted. This means the horn can be left on for a crisp,
clean high end, while the low end is able to deliver punch and growl. Mono full
range systems with passive crossovers can not deliver this type of performance.
With a passive crossover system the horn has to be turned off if the power amp is
over driven, depriving the artist of the his full sound.

3) Full Range ¼'' Input:
Using a standard ¼'' speaker cable, this input jack provides full range operation
with any bass amplifier head.
4) High Frequency Attenuator:
Adjusts the volume level of the horn when the cabinet is in full range mode.
When used in Bi-Amp mode (as with the 700RB), this control is bypassed and
the high frequency level is adjusted by using the Tweeter control on the amp
front panel.
RBH Cabinet setup up for Bi-Amp Operation:
The Bi-Amp feature of the RBH Cabinets is engaged by setting the crossover
switch to Bi-Amp. You must use a true Bi-Amp head such a the GK 700RB, and
connect it to the crossover Speakon connector with a 4 conductor Speakon cable
(supplied with the GK Bi-Amp head). This setup gives the GK Bi-Amp head
complete control of the tweeter and woofer signals sent to your cabinet (the
crossover attenuator is bypassed). Now you can push the woofers to the max.,
while the tweeter remains clean, crisp and free of clipping distortion. In
addition, a smooth tight tone is easily dialed up by adjusting the Tweeter and
Woofer Master controls on the GK Bi-Amp front panel.
RBH Cabinet setup up for Normal Operation:
The RBH series is configured for normal operation (full range) by setting the
crossover switch to full range. In this mode you can use either the ¼” or
Speakon connector for operation. If you are using a Speakon cable you must
connect the amp positive lead to 1+ and the amp negative lead to 1- on the
connector. In this mode the cabinet is setup for full range operation and the
tweeter level is controlled by the crossover attenuator control.

any amplifier.

RBH Amp Clip:
When installed the RBH amp clip is used to hold the amplifier in place while the
cabinet is rocked back. The clip is designed specifically for GK heads like the
700RB. Other heads may be too large or too heavy to use in this manner. To
install the clip simply slip it over the front edge of the cabinet top board. Space
the clip the same distance as the amplifier feet, with the post facing up. The feet
of GK heads like the 700RB will slip snugly over the clip posts and hold the amp
in place as the cabinet is rocked back. Other brand heads may be too large to
work in this application, so we recommend using only GK heads like the 700RB.
