1. AC Receptacle:
The power cord is detachable and plugs in here.
2. Remote Trigger:

"master" and "slave" units. It allows you to turn on all
amplifi ers at the same time, when the "master" unit is
powered on.

Accepts the +12VDC signal from the "master" 2001RB's
Trigger Out jack to activate or turn on, the "slave"
2001RBs when in standby mode.
Out:
Provides +12VDC as a trigger output to remotely turn on a
"slave" 2001RB.
3. Right "Speakon" Outputs:
Enables BI-AMP operation by connecting a GK-RBH Series
cabinet with the provided 4 conductor Speakon cable.
This connects the 50W amplifi er allowing the Tweeter
control on the front panel to control the signal going to
the horn. See Bi-Amp and Normal Operation on page 7
for more information.
4. Right Speaker Out:
540W power amp output for Full-Range operation only.
They deliver 540 watts into 2 Ohms or 360 watts into 4
Ohms. Lower impedances should not be used.

This adjusts the output level of the right channel only in
dual-mono mode.
6. Bridge Mode:

7. Left Speaker Out:
540W power amp output for Full-Range operation only.
They deliver 540 watts into 2 Ohms or 360watts into 4
Ohms. Lower impedances should not be used.
8. Left/Bridged "Speakon" Outputs:
Enables BI-AMP operation by connecting a GK-RBH Series
cabinet with the provided 4 conductor Speakon cable.
This connects the 50W amplifi er allowing the Tweeter
control on the front panel to control the signal going to
the horn. See Bi-Amp and Normal Operation on page 7
for more information.
These "Speakon" outputs also enable "bridged mode"
operation. When in bridged mode, the 2001RB will be in
a simultaneous bridged/Bi-amp mode, since the 50W horn
amplifi ers are always active ( in the clean channel only)
unless you choose to use the "horn mute" feature, via the
RFB-III footswitch.
DO NOT CONNECT ANYTHING TO THE RIGHT
CHANNEL OUTPUTS WHEN IN BRIDGED
MODE!!
DO NOT USE "BRIDGE MODE" CABLES WITH
THIS AMPLIFIER, AS THIS COULD RESULT IN A
MALFUNCTION AND/OR DAMAGE TO THE
AMPLIFIER.
9. Footswitch:
Provides a means to hook-up the RFB-III, three button
footswitch to your amplifi er, with a standard 5 pin DIN
(MIDI) cable. The RFB-III allows remote Channel Switch-
ing (Level A or Level B), Horn Mute (when in the clean
channel) and Tuning Mute.
