Danger
L‘exposition a des niveaux eleves de bruit peut provoquer
une perte permanente de l’audition, Chaque organisme
humain reagit differemment quant a la perte de l’audition,
mais quasiment tout le monde subit une diminution de
I’acuite auditive lors d’une exposition suffisamment
longue au bruit intense. Les autorites competentes en
reglementation de bruit ont defini les expositions tolerees
aux niveaux de bruits:
2. Toutes les recommandations et précautions d'emploi doivent

Bass Control:
Controls the amount of low frequency in the signal.
This control is centered at 65 Hz.
This is a 1/4" 2-conductor input jack for plugging
in your instrument using a shielded instrument
cable. It is intended for bass guitar but will accept
other instruments and line level signals as well.
i
Mid Control:
Controls the amount of midrange frequency in the
signal. This control is centered at 500 Hz.
b
NORM/-12 dB Switch
Set this switch to -12 dB when using an active
bass guitar or line level signal. Setting to -12 dB
will lower the input gain by 12 dB.
j
High Control:
Controls the amount of high frequency in the signal.
This control is centered at 3 kHz.
c
Gain Control:
k
Graphic Equalizer Section:
Controls the amount of input to the preamp.
Adjust so SIG indicator illuminates when notes
are played.
This 9-band graphic equalizer is used to adjust the
sound to the room acoustics. It may also be used to
finely adjust sound to taste.
d
Clip Indicator:
l
Master Volume Control:
Indicates when the input signal has reached
maximum level. If indicator illuminates when
notes are played , set NORM/-12 dB switch to
-12 dB and/or turn down GAIN control.
Controls the overall output of the amplifier. Use in
conjunction with the GAIN control to obtain
desired speaker output.
m
Power Switch:
e
Signal Indicator:
Turns AC power on and off. Note: When power is
first applied, there is a slight delay before sound is
heard through the speakers.
Indicates when sufficient signal is applied to the
preamp. Adjust GAIN control so indicator
illuminates when notes are played.
n
Solo Indicator:
This blue LED is lit when the SOLO mode has
been activated.
f
Mute Indicator:
This red LED will blink indicating all outputs are
muted except for the TUNER OUT (rear panel
#23). Muting can be done by either depressing the
MUTE ON/OFF switch on the front panel or by
pressing MUTE on the footswitch.
o
Solo On/Off Switch: This switch when
depressed, activates SOLO mode. When active, the
signal to the power amp will be boosted by 6dB.
p
Power Jewel:
Indicates when AC power is applied to the
amplifier.
g
Mute On/Off Switch:
When this switch is depressed, all outputs are
muted except for the TUNER OUT (rear panel

Circuit Breaker:
u
Direct Output Jack:
This circuit breaker will trip when too much
current is applied to the amplifier. To reset: Turn
off POWER switch, allow to cool for a few
minutes, then press circuit breaker button, and
turn the POWER switch on. Note: If the Circuit
Breaker trips repeatedly when AC power is
applied, take the amplifier to an authorized service
center for repair.
This is a line level output used to connect the
amplifier to another device, such as a mixer or
recorder.
v
Pre EQ/Post EQ Switch:
When set to Pre EQ, the DIRECT OUTPUT signal
will be unaltered by the EQ sections of the preamp.
When set to Post EQ, the DIRECT OUTPUT
signal will reflect the entire sound (including EQ
settings) of the preamp. Note: The MASTER
volume Control (front panel #12) and SOLO
ON/OFF switch (front panel #15) have no effect on
the DIRECT OUTPUT signal.
r
Power Cord:
This supplies AC power to the amplifier. If the
cord becomes damaged, take the amplifier to an
authorized service center for repair.
s
Speaker Outputs:
w
Tuner Out Jack:
Use this jack to connect to a tuner or other line level
device. This jack is always active and is a pre-gain
output.
Use these jacks to connect the amplifier to
speaker cabinets using heavy duty Speakond
speaker cables. These jacks are connected
together internally. See Amplifier Loading
Chart (Page 8) for speaker cabinet loading
information. Note: To prevent overheating and
possible loss of signal, do not connect a load
lower than 2 ohms. Be sure power is off before
making any speaker connections. To connect a
cable: Align tab on speaker cable connector slot.
Insert and twist one quarter turn clockwise to
lock. To remove a cable: Pull back release button
on cable connector, twist connecter counter
clockwise one quarter turn, and pull out connecter.
x
Effects Send Jack:
Use this jack to connect to the input of an external
effects processor. This jack can also be used as a
preamp out.
y
Effects Return Jack:
Use this jack to connect to the output of an external
effects processor. This jack can also be used as a
power amp in. The preamp output signal is
disconnected from the power amp when using this
jack.
z
Footswitch Jack:
t
Ground Lift Switch:
This 3-conductor 1/4” jack is for connecting a
footswitch (sold separately) to the amplifier. The
footswitch will then control the Mute and Solo
features. Using this jack overrides the front panel
MUTE and SOLO switches.
Activating this switch removes the ground
connection on the DIRECT OUTPUT Jack
(#21). Activate this switch, if necessary to
eliminate hum.

Total load on amplifier Note: To prevent overheating and possible loss of signal, do
not use any combination of cabinets that results in a box that is shaded.
This chart can help you determine what load (ohms) is present on the amplifier when using multiple cabinets.
- To use this chart with two cabinets (A and B), find cabinet A’s impedance (ohms) column and cabinet B’s
impedance row on the chart. The total load on the amplifier is shown in the box where they meet. For example: If
cabinet A’s impedance is 8 ohms and cabinet B’s impedance is 4 ohms, the total load on the amplifier would be 2.67
ohms.
- To use this chart with three or more cabinets, find the total load for two cabinets and then use the result for
cabinet A’s impedance column. The third cabinet will then be used for cabinet B’s impedance row on the chart.
Find the total load on the amplifier and repeat if more cabinets are used. For example (using 3 cabinets): If the first
cabinet (cabinet A) has an impedance of 16 ohms and the second (cabinet B) has an impedance of 8 ohms, the
total load would be 5.33 ohms. Using this load (5.33) as cabinet A’s impedance and a third cabinet’s (new cabinet
B) impedance of 4 ohms, you would find that the total load on the amplifier is 2.29 ohms. Note: It is not
recommended to use any combination of cabinets that has a resulting load in a shaded area of the chart.

Rack Mounting Instructions
The GROOVE 600™ was designed to mount into a standard 2-space rack. When mounting, use 4 screws to
secure the amplifier to the rack. When using only one amplifier, use the bottom 2 spaces in the rack.
However, if more than one amplifier is used, leave one space open between the amplifiers to ensure proper
ventilation (shown below).
