A - PEAK LED INDICATOR  
E & F - OUTPUT CONNECTORS  
The red Peak LED Indicator illuminates when the output volt-  
age of the amplifier reaches clipping (maximum output volt-  
age). The threshold for the peak indicator automatically  
adjusts for load impedance and supply voltage variations.  
Each channel is provided with a single 1/4" phone jack (E)  
and a pair of five-way binding posts (F) which will  
accommodate a single pair of dual banana plugs (multiple  
stacked banana plugs are not recommended as they  
tend to fall out), spade lugs or bare wire. If the speaker  
wire is terminated with spade lugs, make sure that the  
lugs are tin or gold plated brass or copper, not plated  
steel. Non-linear contact resistance phenomena will  
degrade the sonic integrity of any amplifier at the speak-  
er/amplifier interface. The Channel A and Channel B  
outputs are spaced on 0.75 inch (19 mm) centers so that  
one "double banana plug" can be used for bridged  
operation. During performance verification measurements,  
use the five-way binding posts only.  
B - LIMIT SWITCHES  
The Limit Switch is used to defeat the internal compressor circuits.  
C - INPUT LEVEL CONTROLS  
Two continuously variable attenuators control the ampli-  
fier's input sensitivity. Control settings can vary between  
zero attenuation (maximum clockwise rotation) and infinite  
attenuation (maximum counterclockwise rotation). At the  
full clockwise rotation, a +1.8 dBV input signal is required  
for rated output. Each gain control is independent except  
for the Mono Bridge mode where Channel A is the active  
control and the Channel B control is inactive. Refer to the  
Amplifier Operation section for additional information on  
proper adjustment of the input level controls.  
CAUTION:  
Do not operate the amplifier in the two channel  
(stereo) mode with a load impedance of less than  
4 connected to either channel.  
Do not operate the amplifier in the Bridged Mode  
with a load impedance of less than 8 .  
D - POWER LED INDICATOR AND SWITCH  
The power switch turns the unit on and off. To turn the  
unit on, push the power switch to the right. The LED is  
illuminated when the amplifier is turned on and main volt-  
age is present. If this indicator does not light when the  
power switch is turned on (and does not trip the circuit  
breaker), then check the AC power supply.

G - MODE SELECT MONO BRIDGED/STEREO  
L - AC POWER CORD  
This two-position switch (left rear panel) selects either the  
mono bridge or normal stereo mode. With the button in  
the "in" position, the amplifier is in the mono bridged  
mode. With the button in the "out" position, the amplifier  
is configured for the normal two-channel stereo mode of  
operation. In the Bridged Mode of operation, speaker out-  
put is taken across the two red (positive) output terminals.  
The Channel A terminal is the positive output terminal and  
the Channel B terminal is the negative terminal for bridged  
operation only.  
WARNING: This amplifier is equipped with a 3-  
prong, grounding type supply cord. To reduce  
the possibility of shock hazard, be sure to con-  
nect the unit to a grounded AC recepticle. DO  
NOT ALTER THE AC PLUG!  
100-120V OPERATION  
This must be connected to a source of 100V or 120V, 50 to  
60 Hz AC power with a current capability of at least 10 A.  
As a general guideline, it is accepted to connect two (2) SPL-  
6000 amplifiers to one (1) 20 ampere circuit provided the  
load is limited to 4-ohm loudspeakers on each channel and  
the signal source is full range music or speech.  
CAUTION: In the Bridged Mode of operation,  
the load floats and is NOT chassis ground  
referenced.  
H - MODE SELECT, DUAL MONO/STEREO  
220-240V OPERATION  
This must be connected to a source of 220-240V, 50 to 60 Hz  
AC power with a current capability of at least 5 A.  
This two-position switch connects the amplifier inputs  
together to allow channel A and B to be summed (mixed)  
for non-bridged mono operation. In the dual mono and  
the stereo mode of operation, both attenuators control  
their respective channels.  
M - EXTERNAL FUSE  
When necessary, replace the external fuse only with one of  
the same type and rating as shown on the label  
next to the external fuse holder.  
I, J & K - INPUT CONNECTORS  
Each channel is provided with a Female XLR (I) and Male  
XLR (J) connectors for easy "Daisy Chain" operation  
of multiple channels in large systems, and a 1/4" inch tip-  
ring-sleeve (stereo) phone jack (K). Each input is electroni-  
cally balanced and will accept signals from balanced  
sources (either active or transformer) or from unbalanced  
circuits. Pin #2 is the positive pin on the XLR connectors.

BASIC CONNECTIONS and WIRING  
Power and audio signal cables are the most common  
sources of sound system failure. Well-made and carefully  
maintained cables are essential to the reliability of the  
entire system. If long speaker cables are required, make  
sure the wire is of sufficient size to transfer all of the avail-  
Always use stranded wire for three reasons:  
1) It is more flexible and less prone to metal fatigue breakage.  
2) If an end is nicked while insulation is being stripped for  
able amplifier power to the speakers rather than absorbing connection, only one or two strands will break and not the  
power itself. As a rule of thumb, the larger the wire the  
better (larger wire has smaller "gauge numbers").  
entire wire.  
3) There is some evidence, though disputed, that higher  
frequency audio signals flow along the outside of each  
conductor (skin effect): if this is so, the more strands, the  
lower the effective cable resistance to high frequencies.  
Below, we have listed the smallest wires (the highest num-  
bered gauges) recommended for best results. To make it  
simple, we'll assume you are operating under worst case  
conditions with 4 ohm loads. 8 ohm operation will  
improve results with the same wire.  
In cases where speakers and power amplifiers are located  
far away from the signal source (a mixer or a preamp), bal-  
anced line" signal cables are a wise choice.  
Larger diameter (small gauge number) wire is expensive  
and long cables made from it are heavy. Rather than run-  
ning long speaker cables, it is better to locate power ampli-  
fiers near speakers and run a line-level signal cable over the  
long distance to the amplifier. This approach eliminates  
most of the signal loss due to speaker cable resistance so  
the speakers are fed all of the amplifier's power without the  
need for heavy cables. This can actually save money in  
many instances.

The SPL-6000 is timed to turn on the speaker outputs  
after the amplifier's power supply is fully charged up, thus  
preventing any turn-on noise. Timing of the amplifier's  
turn-on circuit is usually sufficient to accommodate all the  
turn-on anomalies from other pieces of gear in a system,  
making it acceptable to use a single switched power string  
in a permanent or semi-permanent system.  
CAUTION: NEVER use coiled cords for  
speaker hookup, even in an emergency.  
Coiled guitar-type cords usually have higher internal resis-  
tance than the speakers themselves. This is due to the  
light-gauge wire used to keep the coil cords flexible.  
These cords will prevent most of the power from reaching  
the speakers. In high power operation, a coil cord can  
melt causing a fire hazard and possible damage to the  
amplifier. As a general rule, both straight and coiled gui-  
tar-type connecting cords make poor speaker cables.  
CAUTION: The SPL-6000 can draw a lot of  
AC power. Be sure the AC power source for  
your AC distribution system has adequate  
current capability.  
The SPL-6000 can produce enough power output to dam-  
age electronic equipment connected to its output. Besides  
being capable of destroying speakers, under certain circum-  
stances shock and /or fire hazards are possible. High power  
amplifiers should always be properly applied and used with  
care in clean and dry environment.  
In multiple amplifier installations, we recommend sequen-  
tial turn-on (either manually or via timed relays) to avoid a  
sudden major drain on the AC line.  
You should keep in mind that the severe reduction of  
power line voltages affects the amount of power you can  
get FROM the amplifier. If you need to run long AC  
extension cords, make sure their conductors are as large  
as practical (small gauge number). Just as smaller diam-  
eter wire causes speaker lines loss, smaller power lines  
cause loss. The effect of small AC lines is one of the  
intermittent clipping under severe conditions.  
If you have mounted all your sound equipment in a rack or  
portable case, you can ensure that everything stays calibrat-  
ed by marking the settings of the necessary controls. Small  
pointers made from masking tape are visible in dim light and  
can be removed with alcohol or rubber cement thinner with-  
out damage to the paint on most front panels including  
those of the Fender amplifiers. Be sure to check the finish in  
an inconspicuous place to determine the suitability of any  
cleanser.  
Assuming you are NOT turning all the equipment on at  
once with a switched power receptacle "strip", be sure to  
turn on the power amplifier last. This will prevent turn-on  
"thumps" from the mixer or other pieces of gear that could  
possibly damage speakers. The reverse logic should also  
be applied -- turn OFF the amplifier FIRST -- when shut-  
ting down the system.
