Front Panel Controls
1-Balanced Direct Out:
An electronically balanced output, that you can run to your P.A. system.
2-Ground/Lift:
This switch disconnects the ground on the balanced, XLR output to eliminate
hum and buzz when connnecting to equipment that is running on a different
ground system.
Pre/Post EQ Button:
Selects the direct out signal before or after the EQ.
3-Direct Level Out
Controls the level at the direct out jack.
4-Input:
A standard ¼" input jack to plug in active or passive basses using a shielded
cord.
5- -14dB Pad:
Input attenuator button. The button is generally left out, except in rare cases
when the clip LED flashes. This switch should be pressed if the CLIP LED stays
on continuously. It may be necessary to "pad" the input if you are using a bass
with active electronics or very high output.
Clip LED:
LED lights yellow when the input stage is being over-driven. If -14dB
PAD is pressed and clip LED still stays lit, turn down the volume on
your bass.
Tuning Mute Button:
Set this switch to "On" when tuning up. No signal will be sent to the speakers,
or the P .A. system.
Mute LED:
LED turns on when "Tuning Mute" is switched to the "ON" position.
6-Volume:
Sets pre-amp gain after the input stage. It is used in conjunction with the input
pad, to optimize the amplifier's headroom.
7-Voicing Filters:
4/5 String Bass:
Setting this button to the "ON" position, voices the pre-amp for basses with
"B" tuning (5 string bass). Leaving it in the "Out" position will voice the amp
like the 800RB, for a 4 string bass.
Contour:
Drops the mid-range frequencies while boosting lows & highs.
Presence:
Adds edge and definition to higher frequencies.
Active Equalization:
8-Treble:
Boost and cut at 7 kHz +14dB shelving type. Add or remove edge and
definition.
700RB-II/1001RB-II Series
9-High Mid:
Boost and cut at 1 kHz +6dB/ -10dB, "Q Optimized," band pass type. Works
on lower string harmonics, and effects the punch of your sound.
10-Low Mid:
Boost and cut at 250Hz +6dB/-10dB, "Q Optimized," band pass type. Works
on the main body of your sound.
11-Bass:
Boost and cut at 60Hz +10dB, shelving type. Controls low end push.
12-Boost:
A post EQ gain stage using GIVE technology which adds "growl" as it is
turned up.
13-Tweeter:
Master volume control for the tweeter (50W) amp..
14-Tweeter Hi-Cut:
Cuts frequencies above 10kHz, producing a more "cone-like" (less metallic/
harsh) sound from the tweeter.
15-Woofer/Master:
Master volume control for the woofer (Main) amplifier.
16-Woofer Hi-Cut:
Press this button to engage the electronic crossover for the woofer. This cuts
frequencies above 5kHz (Rolls off the highs).
17-Effects Loop:
Send and return jacks provided for the insertion of effects after the EQ, but
before the boost section. Some effect units have gain, turning the BOOST
down, will compensate for this.
18-Tuner Output
Output comes directly off the input stage and can be patched to a tuner with
a shielded patch cord. This output is unaffected by the Tuning Mute Feature.
19-Power/Protect LED:
The LED is red at turn-on for five seconds while the amp powers up.
The LED turns blue when the amp is ready to play. Should the amp
experience a fault (over heat, over current) the amp will mute and
this LED will switch to red until the condition is corrected. This
LED turns off when the power switch is turned off.
20-Power Switch:
Turns the amplifier on or off. Should a problem occur during
operation press this switch out first. This turns the amp off, but
does not completely disconnect the power from the AC mains. The
power LED should be off at this point.
