Bridged Mode Operation

Note:
To operate the 2001RB in bridge mode, you must use
the L/BR Speakon outputs only. Using the Left
channel, 1/4" outputs will not work, since the ground
for those jacks are internally disconected when in
bridge mode. Using any of the Right channel 1/4" or
Speakon outputs is not recommended as this will result
in a malfunction, or undesired operation of the
amplifier.
1. Make sure nothing is connected to any of the Right
channel outputs.
2. Slide the Bridge Mode switch on the back of the amp
from Dual mono, to Bridge.
3. 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 Series cabinets, using our
four-conductor Speakon to Speakon Biamp cable will
allow Bridged Mode and Bi-amp operation
simulaneously. Since the 50W horn amps are always
active, this allows youto 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 Bi-amp 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 1/4" 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.
