FUSE REQUIREMENTS
It is absolutely vital that the main power lead to the amplifier(s) in the
system be fused within 18-inches (45cm) of the connection to the vehicle
battery. The value of this fuse (or circuit breaker) should be no greater than
the sum of the fuses found on all of the equipment being connected to that
power wire. NOTE: Due to space limitations, the PBX-Series Amplifiers do NOT
use chassis mounted protective fuses. Therefore you must add a fuse and fuse
holder (not included) Please refer to the recomendations: [PBX-500.4 – 80A]
[PBX-1200.5 – 120A] [PBX-600.6 – 80A] WARNING · Do not install in a
place where it could injure the driver or passengers if the vehicle
stops suddenly. · Upside down mounting will compromise heat dissipation
through the heatsink and
could engage the Advanced Protection Circuitry. · Try to avoid mounting the
amplifier on a subwoofer enclosure, as extended exposure
to vibration may cause malfunction of the amplifier. · Don’t mount the
amplifier so that the wire connections are unprotected or are sub-
ject to pinching or damage from nearby objects. · The DC power wire must be
fused at the battery positive (+) terminal connection.
Before making or breaking power connections at the amplifier power terminals,
disconnect the DC power wire at the battery end. · The battery of the car
audio system must be disconnected until the entire wiring and installation is
completed.

This amplifier is designed to work within a 9-16 volt DC range. Before any
wires are connected, the vehicles electrical system should be checked for
correct voltage supply with the help of a voltmeter. NOTE: Bare wires should
be tinned with solder for maximum current flow. FUSE REQUIREMENTS It is
absolutely vital that the main power lead to the amplifier(s) in the system be
fused within 18-inches (45cm) of the connection to the vehicle battery. The
value of this fuse (or circuit breaker) should be no greater than the sum of
the fuses found on all of the equipment being connected to that power wire.
NOTE: Due to space limitations, the PBX-Series Amplifiers do NOT use chassis
mounted protective fuses. Therefore you must add a fuse and fuse holder (not
included) Please refer to the recomendations: [PBX-500.4 – 80A] [PBX1200.5 –
120A] [PBX-600.6 – 80A] AUTO TURN-ON -SELECTOR SWITCH When put in the REM
position the AUTO ON is disabled , and you will need to run a remote turn on
wire and attach it to the terminal marked REM located between the amplifiers
BATT+ and GND power terminals. Enabling the High Level Auto Turn-on circuit
eliminates the need to run a separate Remote Turn-on Lead but does Require the
use of the optional HL-AD2 wiring Harness (see page 12). When this is in the
DC position it will sense DC Voltage offset or change and will turn on and off
the amplifier. When this is in the SIGNAL position it will sense the input
signal voltage and will turn on the amp or turn off when the signal is not
being passed through its input.
NOTE: It is highly recommended that an Allen wrench is used to tighten the set
screws in the terminal blocks by hand and NOT a power drill. This will prevent
stripping or other possible damage to the amplifier.
HIGH LEVEL INPUT PLUG
The balanced input of this PBX series amplifier can receive either low (RCA)
or high (speaker lead) level signals from the source unit (radio). A high
level signal can be run from the source units speaker lead outputs to the low
level RCA amplifier inputs via the PowerBass HL-AD2 wiring harness (available
separately as shown below.

Fig.5 GAIN Control
MIN MAX
This control allows you to match the input level of the amplifier to the
output level of your head unit. Matching the input can be accomplished in
three simple steps:
1. Set the volume of GAIN on the amplifier to Min (completely counter clock
wise). 2. Turn on the head unit and adjust volume to 2/3 maximum, and set the
BASS and TREBLE to zero. 3. Adjust the GAIN control clockwise until the sound
just begins to distort, then back off slightly to cut
distortion and operate at optimum gain.
Remember, the GAIN control is not a volume control. Ignoring the three steps
above may leave you with damaged speaker and/or a damaged amplifier.

HPF (High Pass Filter) 41 Click Detent Control When you are using coaxial or
component speaker system, this allows you to adjust high-pass X-over frequency
togetbettersoundqualityfromcoaxialorcomponentspeakersystem,werecommendthe
frequency should be higher than 80Hz. Make sure the X-OVER switch is
positioned at “HPF”. See the charts on pages 24-27 to set the High Pass Filter
to the precise frequency for your particular amplifier. *When x10 is selected
this multiplies the frequency by 10 for use with Bandpass tuning on the
PBX-500.4 and PBX-600.6 models only.
Fig.7 Low Pass Control (LPF) LPF (Low Pass Filter) 41 Click Detent Control
Using this volume, adjust the LPF frequency for your subwoofer speaker(s)
operation. The X-OVER switch position should be at “LPF”(not avaliable on
PBX-1200.5 ch. 1-4). Use the enclosed chart to precisely dial in desired
frequency. See the charts on pages 24-27 to set the Low Pass Filter to the
precise frequency for your particular amplifier. *When x10 is selected this
multiplies the frequency by 10 for use with Bandpass tuning on the PBX-500.4
and PBX-600.6 models only.

SPECIAL CONTROLS FOR THE PBX-1200.5
.
BASS BOOST EQ Variable Control This special feature is designed to provide you
more powerful sound quality, and it allows you to adjust the Bass EQ up to
18dB at 45Hz. Keep in mind more is not always better. Setting the control to
the max (18dB) may stress the amplifier and woofer and could result in damage.
SUBSONIC 41 Click Detent Control The subsonic control will filter out all
frequencies below where the control is set and prevent those frequencies from
going to your subwoofer(s). This will prevent your subs from playing any low
frequencies that may harm the speaker. When this amplifier is used with a
subwoofer in a Vented Woofer application it is important to set the frequency
of the filter to cutoff 1/2 octave below the vent frequency. This will prevent
the woofer unloading from bass notes which are too low for the vented woofer.
Once the woofer is unloaded it is operating as a free air driver and may
experience damage by striking the back plate or by shearing off the spider.
Proper setting of the subsonic filter is critical.
SPEAKER WIRING AND CONFIGURATIONS
Speaker Load Keep in mind your PowerBass PBX Amplifier is a high power
amplifier and not a high current amplifier. In other words these amplifiers
require a minimum impedance of 2 ohms STEREO or 4 ohms bridged MONO to operate
trouble free. Lower impedance will send the amplifier into protection and
possibly dam-age the electronics inside and void the waranty. The PBX-1200.5
is stable to 2-ohms on the SUB channel. NOTE: Know your total impedance load
before you make any connections.
Speaker Wiring Choose the correct speaker wire for your application. Most
applications will require a minimum of 16 gauge wire. Route these using the
same precautions as you did when you ran the power cable. Terminate these
wires at the speaker end using insulated speaker terminals (not supplied) or
by soldering the connection. Make sure the speaker connections are positive-
to-positive and negative-to-negative. At the amplifier end, it is very
important that the wires are making solid contact. Strip the wires insulation
back approximately 1/2 inch (12mm) and insert the wires into the appropriate
openings while being careful there are no loose or frayed strands of wire
straying from the terminal. Check to make sure you’ve maintained proper
polarity and balance.
CAUTION Maintaining proper impedance is critical when wiring the Full Range
Digital model amplifiers. Improper wiring can cause severe damage to BOTH the
woofer and the amplifier. Detailed wiring diagrams are supplied with all
PowerBass woofers. IF YOU ARE NOT EXPERIENCED OR UNCOMFORTABLE READING THE
WIRING DIAGRAMS CONSULT YOUR AUTHORIZED POWERBASS DEALER BEFORE YOU ATTEMPT TO
WIRE THE SYSTEM.

41 CLICK PRECISION ROTARY CONTROLS
These controls allow precise setting of the electronic crossover settings on
the amplifier, thus taking the guesswork out of tuning your speakers. Using a
small slotted screwdriver make sure the controls are turned all the way to the
left (counter clockwise). Refer to the chart and count the clicks (advancing
one detent at a time clockwise) until you have reached the desired frequency.
This precise method of setting the crossover controls is available for the LPF
and HPF features on the 2-channel and 4-channel amplifiers. It is available
for the HPF and LPF/SUB features on the 5-channel amplifier. NOTE: Select the

TROUBLESHOOTING TIPS
Problem Power LED not ON
Power LED lights GREEN, no output
Power LED lights GREEN, amp plays at very low volume on one or more outputs
Red Status Protection LED is ON, no output and 1. Amp is VERY HOT
2. Amp shuts down ONLY when the vehicle is running
Alternator noise (varies with RPM)
Poor Bass Response
Solution
With a Volt Ohm Meter (VOM) check: · +12 Volt power terminal (should read +12
to +16VDC · Remote turn-on terminal (should read +12 to +16VDC) · Ground
Terminal
· Check RCA connections · Test speaker outputs with known good speaker ·
Substitute known good Source Unit · Check for signal on the RCA cable
· Short circuit protection is engaged. Check for speaker wires shorted to each
other or the vehicle chassis. Speakers operating below the minimum impedance
can cause this to occur.
· Thermal protection is engaged. Check for proper impedance at speaker
terminals. Also check for adequate air flow around the amplifier.
· Voltage protection engaged. Voltage to the amp is not within the 10-16 VDC
operating range. Have the battery/charging system inspected.
· Check for damaged RCA cable. · Check routing of RCA cable · Check Source
Unit for good ground · Check amp gain setting, turn down if set too high
· Check speaker polarity, reverse the connection of one speaker only.
NOTE: If the Status L.E.D. is activated and glows RED with no speakers connected to the amplifier, and all the power connections are correct, this would indicate an internal problem with the amplifier. Contact PowerBass USA or your local dealer.

POWERBASS ELECTRONICS LIMITED WARRANTY POLICY
PowerBass USA, Inc. offers limited warranty on PowerBass products under normal
use on the following terms:
PowerBass PBX Amplifiers are to be free of defects in material and workmanship
for a period of one (1) year.
This warranty applies only to PowerBass products sold to consumers by
Authorized PowerBass Dealers in the United States of America. Products
purchased by consumers from a PowerBass dealer in another country are covered
only by that country’s Distributor and not by PowerBass USA.
This warranty covers only the original purchaser of PowerBass product. In
order to receive service, the purchaser must provide PowerBass with the
receipt stating the consumer name, dealer, product and date of purchase.
Products found to be defective during the warranty period will be repaired or
replaced (with a product deemed to be equivalent) at PowerBass’s discretion
and will not be liable for incidental or consequential damages. PowerBass will
not warranty this product under the following situations:
· Amplifiers received with apparent rust or corrosion · Any evidence of liquid
damage or exposure to excessive heat · Attempted repairs or alterations of any
nature · Product that has not been installed according to this owners manual
Any implied warranties including warranties of fitness for use and
merchantability are limited in duration to the period of the express warranty
set forth above. Some states do not allow limitations on the length of an
implied warranty, so this limitation may not apply. No person is authorized to
assume for PowerBass any other liability in connection with the sale of this
product.
Please call 909-923-3868 for PowerBass
