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:  
4. Suivre toutes les précautions d'emploi pour utiliser ce produit.

a Guitar Input Jack:  
j High Control:  
This is a 1/4" 2-conductor input jack for plugging  
in your instrument. It is intended for bass guitar  
but will accept other instruments as well.  
Controls the amount of high frequency in the signal.  
The Normal / Define Switch changes the center  
frequency of this control. (See m)  
b Active/Passive Switch  
k Normal / Sub Switch:  
Set this switch to Active when using an active bass  
guitar. Setting to Active will lower the input gain  
by 12 dB.  
When this switch is set to Normal, the Bass  
Control frequency is centered at 100Hz. When this  
switch is set to Sub, the Bass Control frequency is  
centered at 50Hz.  
c Gain Control:  
Adjust clockwise to increase the amount of preamp  
volume. When set too low, the Signal Indicator  
will not light.  
l Normal / Shift Switch:  
When this switch is set to Normal, the Mid  
Control frequency is centered at 800Hz. When this  
switch is set to Shift, the Bass Control frequency is  
centered at 400Hz.  
d Clip Indicator:  
Indicates when the input signal has reached  
maximum level. Note: The Active / Passive  
Switch is the only control on the amplifier that has  
an effect on this. If the switch is set to Active and  
the Clip Indicator still lights, lower the output of  
your instrument to correct.  
m Normal / Define:  
When this switch is set to Normal, the High  
Control frequency is centered at 3KHz. When this  
switch is set to Define, the High Control frequency  
is centered at 5KHz.  
n Graphic Equalizer Section:  
This 9-band graphic equalizer is used to finely  
adjust the sound to taste.  
e Signal Indicator:  
Indicates when sufficient signal is applied to the  
preamp. Adjusting the Gain Control will affect  
this.  
o Master Volume Control:  
Controls the overall output of the amplifier.  
f Mute Indicator:  
This indicator will light when the preamp is muted.  
This can be done by either pressing the Mute  
On/Off Button on the front panel or by pressing  
Mute on the footswitch. Note: The Tuner Out  
Jack will still be active when this is lit.  
p Power Switch:  
Turns AC power on and off.  
q Solo Indicator:  
Indicates when the Solo On/Off Button is pressed.  
This will also light when Solo on the footswitch is  
pressed.  
g Mute On/Off Button:  
When this switch is active the preamp will be  
muted. However, the Tuner Out Jack is always  
active.  
r Solo On/Off Button:  
When this is active, the signal to the power amp  
will be boosted by 6dB.  
h Bass Control:  
s Power Jewel:  
Controls the amount of low frequency in the  
signal. The Normal / Sub Switch changes the  
center frequency for this control. (See k)  
Indicates when AC power is applied to the  
amplifier.  
i Mid Control:  
Controls the amount of mid frequency in the  
signal. The Normal / Shift Switch changes the  
center Frequency for this control. (See l)

t Circuit Breaker:  
y Pre EQ / Post EQ Switch:  
This circuit breaker will trip when too much  
current is applied to the amplifier. To reset: Turn  
off Power Switch, 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.  
When set to Pre EQ, the Direct Output Jack signal  
will be unaltered by the EQ sections of the preamp.  
When set to Post EQ, the Direct Output Jack  
signal will reflect the entire sound (including EQ  
settings) of the preamp. Note: The Master Volume  
Control and Solo On/Off Button have no effect on  
the Direct Output Jack signal.  
u Power Cord:  
z Tuner Out Jack:  
This supplies AC power to the amplifier. If the  
cord becomes damaged, take the amplifier to an  
authorized service center for repair.  
Use this jack to connect to a tuner or other line level  
device. This jack is always active and is a pre-gain  
output.  
v Speaker Outputs:  
{ 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.  
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. (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.)  
| 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.  
} Footswitch Jack:  
This 3-conductor 1/4” jack may be used for  
connecting a footswitch to the amplifier  
(Footswitch model KAC-GFS100 is included with  
the amplifier). The footswitch will then control the  
Mute and Solo features.  
w Ground Lift Switch:  
Activating this switch removes the ground  
connection on the Direct Output Jack.  
Removing the ground connection will eliminate  
related signal hum.  
x Direct Output Jack:  
This is a line level output used to connect the  
amplifier to another device, such as a mixer or  
recorder.

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 1200 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).
