Bridged Mode Operation
Note: To operate the 2001RB in bridge mode, you must
use the L/BR Speakon outputs only. Using the Left
channel, ¼" outputs will not work, since the ground for
those jacks are internally disconnected when in bridge
mode. Using any of the Right channel ¼" or Speakon
outputs is not recommended as this will result in a
malfunction, or undesired operation of the amplifier.
Make sure nothing is connected to any of the Right
channel outputs.
Slide the Bridge Mode switch on the back of the amp
from dual mono, to Bridge.
The Right Level knob on the back of the amp should be
turned all the way up (clockwise) or power output will
be compromised.

Since Bridge Mode operation is only available through
the Speakon outputs, the type of Speakon cable you
need depends on the brand of cabinets that you are
using. When using our RBH or NEO Series cabinets,
using our four conductor Speakon to Speakon biamp
cable will allow Bridged Mode and biamp operation
simultaneously. Since the 50W horn amps are always
active, this allows you to deliver 1080W to your cabinet
and 50W to the horn. When using other brand name
cabinets a two conductor Speakon cable will be needed
but the biamp feature will not work. It is very
important, that these two conductor Speakon cables are
wired correctly. The 1+ pin connects to the tip of the
¼" plug and the 1- pin connects to the shield.
DO NOT USE 'BRIDGED MODE' SPEAKON
CABLES WITH THIS AMP!
These are wired 1+ and 2+ which would connect the
horn and woofer amps together. This could cause
damage to your cabinet and/or the amplifier.
