are designed to offer the artist the ultimate in sound

quality and stage flexibility. They can be played in several positions, upright,

stacked on their sides, or rocked back for close monitoring situations. A unique

interlocking corner design allows the cabinets to lock together in the various

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.

Switches the crossover between Bi-Amp, and Full Range operation. When using

set to Bi-Amp mode. For operation with other mono or bridged amplifiers this

switch should be set to full range.

Using a standard ¼'' speaker cable, this input jack provides full range operation

with any bass amplifier head.

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.

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.

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.

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.
