Introduction
An important member of the PYLE marine MOSFET amplifierseries, we are
pleased to introduce the unique PLMR440PA, a powerful amplifier with public
address capabilities.
This PYLE marine models features both high pass and low pass crossovers.
Forfurtherflexibility
in the use of a subwoofer, a variable bass boost control has
been included. You can control the subwooferlevel with the remote level control
module.
PYLE marine understands that amplifiers are placed in many different kinds of
installations, so we have also included an inputsensitivitycontrol to help you
integrate the amp into your system regardless
of the nature of your inputsource.
A custom microphone is included. Pressing the button
on the microphone will
mute the audio and allow you to be heard easily by others on your boat.
PYLE marine amplifiers are constructed using a special corrosion resistant
coating
on the printed circuit board to prevent damage from the high humidity
of the marine environment.
In orderto prevent the intrusion ofwater into the amplifierenclosure, we
have provided the connections atthe end ofwaterproofwires/cables, and
tightly grommeted the wires as they pass through the end panels.
An additional important, unique component is the rubber pad which seals all
control openings.
What is included?
When first unpacking your newamplified subwoofer, please check first that
the package contains all of the items below. If something is missing, contact
the store where you purchased the product.
• Marine amplifier
• Custom microphone
and mounting bracket
• High inputcable with connector(s)
• Speakeroutputcable with connector(s)
• Remote level controller
• Four(4) mounting screws

Installation precautions
Before you drill or cut any holes, investigate yourvessel's layout very carefully.
Take special care when you work near the gas tank, fuel lines, hydraulic lines
and electrical wiring.
Neveroperate the amplifierwhen it is unmounted. Attach all audio system
components securelywithin the amplifierto prevent damage, especially
in an
accident.
Do not mount this amplifier so that wire connections are unprotected,
in a
pinched condition,
in contactwith any metal surfaces in your marine vessel,
or likelyto be damaged by nearby objects.
Before making or breaking power connections in yoursystem, disconnect the
marine vessel battery. Confirm that your head unit
or other equipment isturned
offwhile connecting the inputjacks and speaker terminals.
If you need to replace the powerfuse, replace it only with a fuse identical to that
supplied with the amplifier. Using a fuse of a differenttype or rating may result
in damage to youraudio system or your amplifierwhich is not covered by the
manufacturer's warranty.
Don't misuse the
level controll
Do notmistake the Input level control for a volume controlI It Is designed
ONLYto match the output level of your audio source to the input level of
your amplifier.
Do not adjust this Input level to maximum unless your Input level requires It.
Ignoring these instructionswill result in an inputoverload to the amplifier,
and excessive audio distortion. It can also cause the protection circuit to
engage.

Low Level Input Wiring
Low-level (RCA) inputwiring is preferred for bestaudio performance. Always use a
high-quality RCAcable forbest audio performance.
NOTE: Do not connect BOTHthe high level and low level inputs from
your receiver to your amplifier at the same timel

High Level Input Wiring
The high level input(s) should only be used when your head unit lacks RCA
outputs. If the RCAoutputs are not present, connect the speakeroutputs
from the receiver to the high level inputconnector
of the amplifier. Be sure
to observe polarityto avoid audio phase problems.
NOTE: Do not connect BOTH the high level and low level inputs from
your receiver to your amplifier at the same timel

Microphone Input Wiring
If you wish to use the public address feature in the PLMR440PA, all you need to do is
to connect the custom microphone included with the amp.
When you press the button on the microphone, it automatically cuts
off the inputto
Channels 1-4 from youraudio source and presents the microphone signal to the
amplifier.
You can use the microphone to supplement either2CH or 4CH audio inputfrom your
signal source. In any case, when the mic switch is engaged, your audio input will be
silenced until the switch is released.

Speaker Wiring
Tri-Mode
Tir-mode operation allows you to connect this amplifierto a pair of main speakers
plus a subwoofer on one pair of output channels. The main speakers will operate
in STEREO while the subwoofersimultaneously operates in MONO.
To set the amplifierto run in this mode, put the crossover switch In the FULL
posifion. Inserthigh pass filter capacitors and a low pass filter inductor into the
wiring as shown below. Be sure to checkthe table at the bottom
of this page to
determine the correct capacitor and inductorvalues for the crossoverfrequency
you wish to achieve.

Troubleshooting
Before removing your amplifier, refer to the list below and follow the
suggested procedures. Always test the speakers and theirwires first.
Amplifier will not power up.
Check forgood ground connection.
Checkthat remote DC terminal has at least 13.8v DC.
Checkthat there is battery power
on the +terminal.
Check all fuses.
Checkthat Protection LED is not lit, Ifit is lit, shut offamplifier briefly
and then repower it.
High hiss or engine noise (alternator whine)in speakers.
Disconnect all RCA inputs to amplifier(s)-ifhiss I noise
disappears, then plug
in the component driving the amplifier
and unplug its inputs. Ifhiss I noise disappears, go on until
the faulty I noisy component is found.
Itis best to set the amplifier's input level as insensitive as
possible. The best subjective SIN ratio is obtainable this way.
Try to drive as high a signal level from the head unit as possible.
Protection led comes on when the AMPLIFIER is powered up.
Check forshorts on speaker leads.
Checkthat the volume control on the head unit is turned down low.
Remove speaker leads, and reset the amplifier. Ifthe Protection
LED still comes on, then the amplifier is faulty.
Amplifier (8) gets very hot.
Checkthat the minimum speaker impedance for that model is correct.
Check for speakershorts.
Checkthat there is good airflow around the amplifier.
In some
applications, an external cooling fan may be required.
Distorted sound
Checkthat the Level control(s) is set to match the signal level of the head unit.
Checkthatall crossover frequencies have been properly set.
Check forshorts
on the speaker leads.
High squeal noise from speakers
This is always caused bya poorly-grounded RCA patch cord.
