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:

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:

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  
#23). Note: Using footswitch overrides this  
switch.

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).
