700RB Series
Bi-Amp and Normal Operation
The 700RB’s unique design allows for easy setup into Bi-
Amp or Normal configurations. The operational mode is
configured by how you connect your speaker cabinets. In
addition, you have the option of driving one cabinet in
Bi-Amp and one with Normal operation.

The Bi-Amp feature of the 700RB series is automati-
cally engaged when you connect an RBH series
cabinet (with switch on the cabinet set to Bi-Amp) to
the 700RB with the supplied 4 conductor Speakon
cable. This setup gives the 700RB complete control of
the tweeter and woofer signals sent to your rig. 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 in by adjusting the Tweeter and Woofer Master
controls on the 700RB front panel. Note: In the Bi-
Amp configuration, we recommend starting with the
Woofer X-Over and Tweeter Hi-Cut controls in.
700RB setup up for Normal Operation:
The 700RB series amplifier is configured for
normal operation when you are connecting to any
cabinet with a 2 conductor Speakon cable, 1/4” to
1/4” speaker cable or 1/4” to banana plug speaker
cable. In this setup, the speaker cabinet is driven
by the 380W amp and the 50W tweeter amplifier is
not used. If you are using RBH series cabinets, the
volume of the tweeter (relative to the woofer’s
volume) can be adjusted using the Horn Level
control of the cabinet’s internal crossover.
