2001RB & 2001RBP
Quick Start
The 2001RB is designed to be simple to operate.
All controls have a well defined purpose and are well
behaved. These directions will take you through the
basics and give you a good start for setting up your
sound.
1. Plug it in:
Set the power switch to Off and connect the supplied
power cord, from the amplifier AC receptacle, to an AC
power outlet of proper voltage and power rating (see
safety information on page 5 for details).
2. Connect your cabinets:
Connect your speaker cabinet(s) to the LEFT or
RIGHT 1/4” speaker jacks or Speakon outputs if
using our RBH series cabinets. Be sure not to exceed
the maximum recommended speaker loads below.
Maximum Recommended Speaker Loads:
Two 4 ohm or four 8 ohm cabinets per side in dual
mono mode. One or two 8 ohm horns per side on the
50W amp. To connect other manufacturer’s cabinets,
use the LEFT or RIGHT 1/4” jack speaker outputs
only.
If you are using an RBH Series cabinet, use the
supplied 4 conductor Speakon cable to connect to the
“Speakon” outputs on the rear panel of the amplifier.
In addition, set the switch on the RBH cabinet to Bi-
Amp.
For more information on Bridged mode and Bi-Amped
mode, see pages 10-11.
Caution:
Do not connect the Speakon cables labeled “Bridge
Mode” to the 2001RB. This may result in damage to
the amplifier.
3. Initial front panel control settings:
Set all EQ controls and the Boost control to 12
o’clock. The Voicing Filters should be turned all the
way down to get a flat response. Set the Level and
Master Volumes at 0. If you have a five string bass,
push the button marked String Bass in. Make sure the
Level A/B button is out, so you are in the clean
channel.
4. Plug in your bass:
Using an instrument cable, connect your bass to the
Input jack and press the power switch on. If you have
active tone controls on your bass, turn all of the
controls to the middle or flat position and turn the
volume all the way up. If you have conventional,
passive tone controls, turn all tone and volume
controls all the way up.
5. Level and Master Volume settings:
Set the Master Volume to 12 o’clock. Turn the Level-A
volume up as you play. Try not to turn it past 1
o’clock if you have a bass with active tone controls
unless you want an overdrive effect. If the yellow clip
light turns on, press the -10db button in. If it is still
on, try turning the volume down on your bass.
At this point:
You should be hearing your bass quite well. You can
use the Volume and Woofer-Master to achieve a
com fortable sound level.
Remember: If you need
more volume, turn up the Woofer-Master control first.
