INSTALLATION

You will need to install an in-line fuse or circuit breaker in
the power wire within 18" of the battery. This fuse or circuit
breaker is to protect your vehic le fr om fire in case the power
wire shorts to the vehicle body. If you are only using one

amplifier, use the fuse rating indicated in this chart. If you are
using more than one amplifier, add up the fuse ratings for all the
amplifiers. This sum is the rating for your fuse or circuit breaker.
You may also want to add a power distribution block near your
amplifiers to keep the wiring tidy.

Fuse requirements

Amplifier Maximum Fuse Rating

Pro6800

BA CK TO CONTENTS

The following is a basic formula to be used as a guide to determine current
draw. A 50% amplifier efficiency rating is used as an average. Your new

POWERCLASS

™

amplifier is more efficient, other amplifiers will probably
be less. This formula is to be used as a guideline. Using wire of a larger
gauge can only improve the current transfer of your system. Do not use
smaller gauge wire.

Total RMS output x 2 = Total Input Wattage
Total Input Wattage

= Current Draw (in Amps)

Supply Voltage

Example: A

POWERCLASS

™

Pro6800

amplifier has six channels at 50
watts RMS per channel into 4 Ohms (50 x 6 = 300). You would use the
formula in the following way:

300W x 2 = 600W
600W

= 50A Total current draw.

12V
If the same amplifier is driven into a 2 Ohm stereo or 4 Ohm mono load,

double it's 4 Ohm RMS rating. All

POWERCLASS

™

amplifiers will effectively

double their power at this load.
300W x 2 x 2 = 1200W

1200W

= 100A Total current draw.

12V
If you are using more than one amplifier, add up the total current draw

for all of them and choose the appropriate gauge based on the grand total.

Before beginning, disconnect the negative (-) terminal of the
battery prior to working on the positive (+) terminal to prevent
a short to ground. This is important, unless you want to spend
the rest of your life with a nickname like

"Sparky,"

or

"Smokey."

Reconnect the negative terminal only after all connections have

Grounding

Locate an area near the amplifier(s) that is metal and clean
an area about the size of a quarter to bare metal. Inspect the
area around and underneath to be sure you won't drill into wires,
brake or fuel lines, etc. Drill a pilot hole in the middle of this
area. T erminate the ground wire with a ring connector and attach
it to the bare metal using a #8 sheet metal screw and washer
or preferably, a bolt, nut and a star washer (not supplied). We
suggest crimping and soldering this connection. After the
connection is complete, coat the area (on both sides) with
silicone or some similar material to prevent rust from
developing on the bare metal.

If your grand total current draw is over 50 amps (or total output
power is over 300watts), you should run a ground wire beside
your power wire from the battery to the amplifier(s) in addition
to your regular ground wire. Keep the ground and power wires
as close together as possible, and use the same gauge wire
for both. This will ensure that you have a good ground path,
and may eliminate such potential problems as engine noise
and overheated amplifiers.

Charging System Considerations

If your grand total current draw is over 100 amps (or total output
power is over 600watts), you are probably exceeding the
capability of your charging system. Dimming lights and
fluctuating voltage are solid indicators that you need to upgrade
your alternator, battery (or go to multiple batteries), or both.
Keep in mind that your amplifiers simply convert electrical
energy to acoustical energy, and any electrical deficiency will
compromise the performance of your sound system.

Once you have run both the power and ground wires, it's time
to connect the cables to the amplifier . Cut off excess wire and,
using wire strippers, strip the ends of the power and ground
cables approximately 1/4 inch. Locate the

PowerLock

power
and ground connector (supplied). With a small flat bladed screw
driver , loosen the screws before attempting to insert the cables.
Insert the wires into the appropriate hole, and tighten the
screws. Once the wires are secure, the

Bridging

Any or all pairs of channels (1/2, 3/4 or 5/6) on your

POWERCLASS

™

multi channel amplifier are capable of being
bridged into a 4 ohm mono output without switches or bridging
modules (2 ohm mono on Channels 5/6). This feature permits
the creation of a mono channel for a subwoofer or center
channel.

Deriving the mono channel is accomplished by using the left
channel positive wire of the pair as the positive speaker wire
and the right channel negative wire as the negative speaker
wire. You should always be working with the wires of a single

POWERLOCK

speaker connector when bridging a pair of

channels.

NOTE: It is important that a minimum 4 ohm impedance is

observed (2 ohm mono on Channels 5/6). If the impedance
drops significantly below 4 ohms while the amplifier is wired
in the bridged configuration, the amplifier's protection
circuitry may engage.

Mixed Mono Output

The ability to run stereo speakers while simultaneously running
a mono output from the same channel pair is accomplished by
running the stereo speakers normally and tapping into the
appropriate wires for the "mixed mono" channel (left channel
positive for the positive speaker wire and right channel negative
for the negative speaker wire). Total speaker impedance should
be no lower than 2 ohms on the stereo channels and 4 ohms
on the mono channel.

NOTE: Passive crossovers must be used for "mixed mono"
operation. Choose a low pass crossover around 100Hz for
your subwoofer, then choose a high pass crossover for your
stereo channels. The high pass crossover must be at the same
or slightly higher frequency than the low pass crossover to
maintain the correct impedance. See your

PrecisionPower

dealer or call

1-800-62POWER

for more information about

passive crossovers.

There are two sets of RCA INPUTS on the front end of your
amplifier. Plug the RCA cables from your head unit into the
appropriate set of inputs, front and rear. If your head unit
doesn't have RCA outputs don't worry. Simply add a set of
RCA plugs (available at your dealer) to your front or rear set of
speaker leads (see drawing below), plug them into the input
jacks, and push in the -12dB switch.

Balanced Differential Inputs

This circuitry reduces noise radiated into your signal cables by
up to 40dB. This is equivalent to a noise reduction of
approximately one hundred times what the noise level would
be without this circuitry. It provides all the benefits of a true
'balanced' line without the need of any special cables (see
diagram below). This type of input works with any conventional
RCA cable.

WARNING:

If you are using a source unit with bridged high powered (or

"floating ground") speaker outputs, a suitable high to low level adapter
must be used. If you are unsure about your head unit see your local
PrecisionPower dealer or call 1-800-62Power.

The first row of controls on the top of your

Pro6800

allow you
to send a variable highpass signal (20 Hz to 20 KHz) to
Channels 1/2. (12dB/octave) With the X10 switch in the "out"
position, crossover adjustment can be made by turning the
highpass dial up or down for crossover points between 20 Hz
and 2000 Hz. By pressing the X10 switch "in" you are able to
make crossover adjustments between 200 Hz and 20 KHz. A
separate gain control is designated for these channels and
should be adjusted according to page 16.

The second row of controls on the top of your

Pro6800

allow
you to send a variable highpass or bandpass signal (20 Hz to
20K Hz) to Channels 3/4. These controls operate in the same
fashion as above. The first set of controls are the highpass
side of the bandpass, and the second set of controls are the
lowpass side of the bandpass. In order to get a full highpass to
20 KHz press the second X10 switch in and turn the second
(lowpass) dial fully clockwise to 20 KHz position.

The third row of controls on the top of your

Pro6800

operate in
the same fashion as Channels 3/4 crossovers. However, you
have one more option on these channels: you can select a
bandpass crossover (bandpass 2 - third row) or lowpass (fourth
row). By leaving the LP/BP switch out the bandpass 2 signal
will be assigned to CHANNEL 5/6 and lowpass assigned to the
RCA outputs.By pressing the LP/BP switch in, the lowpass
(fourth row) will be assigned to CHANNEL 5/6 and bandpass 2
assigned to the RCA OUTPUTS. The lowpass dial can be
adjusted from 50 Hz to 500 Hz and provides a 24dB/octave
slope.

BA CK TO CONTENTS

INPUT COMBINE and GAIN

Input Combine

Your multi channel

POWER

CLASS™

amplifier can use both
front and rear outputs from your head unit to maintain the
ability to fade front to rear, or you can run a single set of
RCAs to the front inputs and push in the COMBINE switch
on the amplifier end plate to route the INPUT A signal to
channels 3/4 as well.

PSC Switch

Channels 5/6 will be used as subwoofer channels in most
cases, and therefore receive summed information from Inputs
A and B. This allows Front/Rear fading without affecting the
subwoofer level. In order to use a

PSC-221

phase shift
controller on bandpassed midrange drivers (Channel 3/4)
without causing cancellation in your subwoofer channels, you
can isolate Inputs B to Channel 3/4 only by pushing the PSC
switch 'IN'.

Adjusting The Amplifier Input Gain

1. Adjust all amplifier input gain controls to just above minimum
sensitivity (fully counterclockwise).

2. Using the cleanest source (CD), with music playing turn up
the head unit until you can hear distortion. Now turn it down
a bit until you cannot hear the distortion.

3. Increase the Amplifier gain (clockwise) until the onset of
audible distortion. Then decrease the gain to the point just
before the distortion starts. This setting minimizes
background noise and prevents overload.

4. Repeat step 3 for any remaining amplifiers in the system.

Heatsink Cooling

The unique heatsink on
your

PO WERCLASS

™

amplifier
has been designed with fins
on the inside of the aluminum
mass. This allows for the
transfer of heat from the
circuitry to the heatsink fins
and out through the vents
in the endplates. Be sure you have ample space around the
amplifier for cooling, at least 2" on all sides.

Central Muting is engaged.
Remote turn-on wire must have
more than 8 volts to release
central muting. Check Remote
turn-on at the head unit. You may
need to install a relay if the head
unit doesn't put out sufficient
voltage.

TROUBLE SHOOTING

AMPLIFIER TURNS DOWN

Both excessive temperature and low impedance (or short circuit)
conditions will activate the amplifier's AM IV protection circuitry , which
turns down the amplifier's output. When the amplifier cools down, or
the impedance is corrected, the AM IV will restore full power.
If your amp is turning down check your speakers and wiring for low
impedance and short circuits.Also,ensure that there is nothing blocking
the normal convective airflow of the amplifier. No obstruction should
be within 2" of the amplifier on all sides.

NOTE: Low battery voltage will cause the amplifier to run warmer.

NO SOUND ON BANDPASS CHANNELS

Be sure that crossover points are
set properly. Is the highpass set
at a higher frequency than the
lowpass or the lowpass set lower
than the highpass, creating a no
pass?

YES

Readjust crossovers and then
test system again.

STILL NO SOUND - See your Authorized

PrecisionPower

Dealer or Call

1-800-62POWER

.

NO

Check speaker wiring for short
circuits or loose connections. Be
sure that powerlock plugs are in
place properly (screws facing up)
and observe correct wiring
diagram.

NO SOUND IN BRIDGED MODE
