[. . . ] To get the most out of your new purchase please take a few minutes to read through this manual. Your Cabinet should have come with the following items, please check the contents of the box to ensure that you have everything. Included with your 210RBH Cabinet: 210RBH RBH Amplifier Clip Owner's Manual Warranty Card Included with your 410RBH or 115RBH Cabinet: 410RBH or 115RBH RBH Amplifier Clip Swivel Castor Owner's Manual Warranty Card Always Listening I have never seen the point in doing things the way others have done them. [. . . ] 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 positions. When used in the rocked back position, the included RBH Amp Clip allows GK amplifiers such as the 700RB to be mounted on top. All RBH cabinets utilize a unique crossover system, providing easy setup for BiAmp or Normal (full range) operation. If you have a GK Bi-Amp head, such as 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. 2) Bi-amp / Full Range Switch: Switches the crossover between Bi-Amp, and Full Range operation. When using this cabinet with a GK Bi-Amp head such as the 700RB, this switch should be set to Bi-Amp mode. For operation with other mono or bridged amplifiers this switch should be set to full range. 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. Crossover: 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. [. . . ] Pins 2+ and 2-, connect the 50 Watt amplifier to the horn. By using only pins 1+ and 1- this connector may be used for full range operation with any amplifier. 3 RBH Series Cabinets Specifications 210RBH 410RBH/8 410RBH/4 115RBH Cabinet: Power Handling: Impedance: Port Style: Rock Back Dimensions: 800W 8 Ohms Two Front Vents Yes Yes 24''W 24''W 20''H 27. 5''H 15. 5''D 18''D Weight: 55 lbs 100 lbs Covering: Black Carpet Construction ¾ '' Birch With Dado Joints Removable Castors No Yes 400W 8 Ohms 800W 4 Ohms Yes 24''W 27. 5''H 18''D 100 lbs 400W 8 Ohms Yes 24''W 27. 5''H 18''D 75 lbs Yes 4xP10/200 Cast Frame 1xP508 Yes Yes Yes 1xP15/400 Cast Frame 1xP508 Yes Yes 18dB/Oct.
