Your Backline unit 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.
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).
Connect your speaker cabinet to the amplifier output
marked 175W. Be sure not to exceed the recommended
speaker load listed below.
One 4 0hm or two 8 ohm cabinets. One 8 ohm cabinet is
okay.
If you are using an RBH/SBX series cabinet, set the
crossover switch to full range.
Set all EQ controls and the Boost control to 12 o'clock.
The Voicing Filter should be turned all the way down (or
switched off) to get a flat response. Set the Gain, Level-A,
Level-B and Master Volumes at 0. Set the A/B switch to off
(Channel A).
Using an instrument cable, connect your bass to the Input
jack and turn the power switch on, set the master control
to 3 o'clock, slowly bring the Level-A volume up and play.
If the clip LED flashes excessively, push the button marked
10db in. Occasional clip light flashes while playing very
-
hard is okay. Do not turn the volume control in the input
section past 1 o'clock unless you want an overdrive effect.
If you have a bass with passive electronics make sure the
controls are all the way up. If you have a bass with active
electronics, turn all of the EQ controls on the bass to the
middle or flat position.
You should be hearing your bass quite well. You can use
the volume and Master to achieve a comfortable sound
level.
Now you are ready to check out the overdrive feature
(Channel-B). Push in the Level A/B button. The over-
drive LED should light. Set the Gain control to 9 o'clock
as a starting point. Slowly raise the Level-B volume to the
desired sound level. This will give a slightly distorted
sound. Raising the gain will add more distortion and
sustain. (See Sound Tips for more detail).
