Operating Instructions 200MB/200RCB
The Basics
Your new G-K Bass amplifier represents the latest advances
technology has to offer. With a built in limiter, chorus, 4 band
EQ, two voicing filters and a master volume; the number of dif-
ferent sounds available is endless.
A careful examination of this manual will help you get the most
from them.
LEFT TO RIGHT ON THE FRONT PANEL
Input Jack
The input jack is a standard ¼²jack capable of handling a wide
variety of signal levels up to 9v RMS.
Volume
This knob controls preamp volume and limiter threshold. This
will control your overdrive sound or sustain when limiter is on.
Voicing Filters
The contour switch "rounds" out the tone by putting a dip in the
midrange frequencies and boosting the bass and treble. The high-
boost switch boosts the high frequencies for a brighter sound.
Also can be used to "liven" up old and worn strings.
4 Band EQ
1. The first knob is an active treble control operating at 4.0 kilo-
hertz. It adds high end and brightness to your sound.
2. The second knob is an active high mid-range control operat-
ing at 1.0khz. This controls the punch and definition of your
tone.
3. The third knob is an active low mid-range operating at 250hz.
This adds to the meat or body of your sound.
4. The last EQ knob is an active bass control operating at 60hz.
This controls the bottom end or boom of your sound.
Limiter
With the master up full the limiter will prevent the power amp
from distorting.
With the master on lower settings, the limiter will give you
smooth distortion free sustain, with the level controlled by the
master setting. Raising the volume level increases sustain.
Master
The master volume controls the total output from off to full
power.
Chorus on/off
The chorus is a fully adjustable, studio quality effect unit built
right into your amp, It incorporates a high technology IC chip to
give a full chorus enhancement of your sound.
Phones
The phones jack is a ¼'' stereo jack. It delivers a stereo signal for
use with high impedance head phones(600ohm or greater).
Plugging into the phones jack does not disconnect the speakers.
To disconnect the speakers use the switch on the rear panel.
Effects Loop
The effects loop is provided for the insertion of external effects.
It is post EQ and pre internal effects. Using standard guitar
cords, connect the send of the amp to the input on the effect unit
; connect the output of effect to the return on the amp. The level
is 150 mv with master up full.
Direct Outs
Both wet and dry low impedance direct outs are provided with
your amp for professional recording capabilities. The wet direct
signal contains effects and is controlled by the master volume.
The dry direct has no effects and is not affected by the master
volume.
Internal Speaker on/off (200MB)
You have the ability to turn off the internal speaker with this
switch.
External Speaker Jack
This jack is for use with an external speaker cabinet. With the
internal speaker on, you can add on 8 ohm load. With the inter-
nal speaker off, you can add a 4 ohm load.
Power Switch
The power switch on the 200MB is on the rear panel. The power
switch on the 200RCB is on the front panel lower right.
Power Cord
The power cord is detachable and plugs into a socket on the rear
panel. If a replacement cord is used or needed it should be UL
rated at 10amp, 125v; or if using 240v, the cord should be UL
rated at 5 amp, 240v.
Fuse
Never operate your MB or RCB with any other than the recom-
mended fuse.
115v operation - type TSC2A
240v operation - type TSC1A
Maintenance
Your new amplifier is rugged. It was built to give you a lifetime
of trouble free operation. If it is operated with care, your only
maintenance problems should be cleaning. We recommend a
soft damp cloth and mild soap for cleaning outside surfaces.
Your amp can be serviced at any GK authorized service center or
at the GK factory if needed.
