Front Panel Features
(1) INPUT JACK
1/4'' phone jack to plug in active or passive basses with a
shielded cord
(2) -10 dB PAD
This switch should be pressed if the CLIP(3) light stays on
continuously. It may be necessary to "pad" the input if you are
using a bass with active electronics or very high output.
(3) CLIP
LED indicator which lights when the input stage is being over-
driven. If -10dB PAD (2) is pressed and CLIP(3) still stays lit,
turn down the volume on your bass.
(4) TUNING MUTE
Switch that mutes all outputs from the amplifier (speakers, direct
and balanced outs) so you can tune up without sending signal to
the audience or the P.A.. Tuning mute can be footswitch con-
trolled by using a G-K RF2 footswitch, which will leave both
hands free to tune your instrument. To control TUNING MUTE
by footswitch, TUNING MUTE (4) switch must be "in"
(5) LED INDICATOR
Lights when TUNING MUTE is activated.
(6) VOLUME
Controls signal level at the beginning of preamp stages.
Volume should be turned up until the CLIP(7) light comes on
when you're hitting your loudest notes. At this setting you will
have the optimum signal/noise ratio. Remember that your set-
tings in the VOICING FILTER and ACTIVE EQUALIZATION
sections can also cause clipping. IF this occurs, re-adjust
VOLUME as explained above.
(7) CLIP
LED indicator that lights when either VOLUME, VOICING
FILTER, OR ACTIVE EQUALIZATION stages are being over-
driven.
(8) BOTTOM
Voicing filter which boosts or cuts +/-12dB at very low frequencies
(20Hz center freq.). Boost this control if you want to add more
low-bass response. Or, keep it turned down if you want a tighter,
less "boomy" bottom end.
(9) CONTOUR
Voicing filter that boosts highs (4kHz) and lows (80Hz), while
dropping out mids (600Hz).
between half and maximum to create a "round" or "hi-fi" sound.
Use lower settings for a "flatter" response.
(10) PRESENCE
Voicing filter that boosts high frequencies (6.5kHz center freq.)
by as much as 12dB. This control adds "edge" to help you cut
through the mix.
(11) - (14) ACTIVE EQUALIZATION
Four highly active tone controls, TREBLE, HI MID, LO MID,
AND BASS. Each band of EQ creates wide tonal variations
without affecting the other bands.
(15) BOOST 1
A post EQ gain stage using GIVE Technology which adds
"growl" as you turn it up. The RF2 footswitch allows you to
switch between BOOST1 and BOOST 2.
(16) LED INDICATOR
Lights when you have footswitched into the BOOST 2 mode.
(17) BOOST 2
A post EQ gain stage like BOOST 1, except this stage has higher
gain for "lead-bass" or solos. Use BOOST 2 with LEVEL (18)
to create the desired amount of overdrive. Note: You can only
access the BOOST 2 section via the RF2 footswitch.
(18) LEVEL
Determines the level coming out of BOOST 2 section. Used to
set a different volume level for solos.
(19) AUX LEVEL
Controls signal level coming from AUX IN(26). Creates effects
blend (dry vs. wet) when used in a "parallel" effects loop.
(20) MASTER
Master volume that controls output level to speakers.
(21) POWER SWITCH
(22) PROTECT
LED indicator that lights on power up, power down, or when-
ever the FAULT DETECTION CIRCUITRY relays have discon-
nected the 1000RB from your speakers.
(23) CLIP
LED indicator that lights when the output is clipping.
(24) POWER
LED indicator that lights during normal operation.
