(45) & (46) 1/4'' CONNECTORS
Provided as back-up outputs for the RIGHT/HIGH channel. 1/4''
connectors do not have the same power handling as Speakon
connectors, and should only be used if Speakon
unavailable. Caution : You may not connect less than a 4 ohm
load to either of these 1/4'' connectors.
(47) & (48) SPEAKON
Deliver power from the LEFT channel ( if you are in "Stereo
MODE"), LOW channel ( if you are in "Bi-amp Mode"), or
BRIDGED ( if you are in "Bridge Mode") to your speaker(s).
Cables with Speakon
connectors are recommended because of
the high power/current output of the 2000RB. Refer to section
title "CHOOSE AN OPERATING MODE AND HOOK UP
YOUR SPEAKERS" for recommended Speakon
Remember, if you are in the "Bridge Mode", you will need spe-
cial Speakon
Bridge Cables.
(49) & (50) 1/4'' CONNECTORS
Provided as back-up outputs for the LEFT/LOW channel. 1/4''
connectors do not have the same power handling as Speakon
connectors, and should only be used if Speakon
unavailable. Caution : You may not connect less than a 4 ohm
load to either of these 1/4'' connectors. If you are in "Bridge
Mode" these 1/4'' connectors are not functional.
(51) AC RECEPTACLE
Plug the power cord that is included with the 2000RB into this
receptacle.
Selecting an
Operating Mode &
Hooking-up your speakers
Before you power up your 2000RB, you must select the operat-
ing mode that is best for your situation : Bridge Mode, Biamp
Mode, or Stereo Mode. This choice will largely be determined
by the impedance and power handling of your speaker cabinets.
The following table will help to show you how much power you
can put into your speakers for each operating mode:
A note regarding speaker cable: The 1000RB is capable of
delivering more power than typical speaker cables can handle.
Therefore, at the end of each of the following sections, special
Speakon
equipped cables are recommended. Choose cables
that match the connectors on your cabinets. These can be
purchased through your G-K dealer.
BRIDGE MODE :
"Bridge Mode" allows you to put the most power into the fewest
speaker cabinets. Note: You can not operate the 2000RB in
cable are
CONNECTORS
cables.
cables are
"Bridge Mode" without special "Bridge Mode" cables.
In "Bridge Mode" both of the 2000RB's 500 watt power amps
are connected together to drive your speakers. This allows you
to put the maximum power (1000 watts) into a 4 ohm load (two
8 ohm speakers, or one 4 ohm speaker). Remember, you can not
drive less than 4 ohms (no more than two 8 ohm speakers, no
more than one 4 ohm speaker). You can drive a single 8 ohm
speaker, but it must be able to handle 700 watts. Make sure your
speaker cabinets can handle the power.
For "Bridge Mode" operation put the BRIDGE MODE switch
(42) in the ON position. The BIAMP switch (33) must be in the
FULL RANGE position or else only low frequencies will be sent
to your speakers. You will need a "Bridge Mode" cable equipped
with a Speakon
connector to connect each of your speaker
cabinets to jacks (47( & (48). Obviously, if you are using only
one speaker cabinet, you will use one Speakon equipped cable
to connect to either (47) or (48)
