The Safety of Your Ears is in Your Hands

Get the most out of your equipment by playing it at a safe level—a level that lets the sound come through clearly without annoying blaring or distortion and, most importantly, with-out affecting your sensitive hearing. Sound can be deceiving. Over time, your hearing
“comfort level” adapts to higher volumes of sound, so what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
ESTABLISH A SAFE LEVEL:

• Set your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, without distortion.
• Once you have established a comfortable sound level, set the dial and leave it there.

BE SURE TO OBSERVE THE FOLLOWING GUIDELINES:

• Do not turn up the volume so high that you can’t hear what’s around you.
• Use caution or temporarily discontinue use in potentially hazardous situations.
• Do not use headphones while operating a boat; the use of headphones may create a traffic hazard and is illegal in many areas.

Before connecting/installing

WARNING

• To prevent fire hazard, the heatsink should never be covered (such as by paper, material, etc.).
• This unit is for boats with a 12 V battery and negative grounding. Before installing, check the battery voltage.
• When installing this unit, make sure to connect the ground wire first. Ensure that the ground wire is properly connected to the neg-ative ground circuit of the boat. Use adequate gauge, marine grade electrical wire that has been properly terminated for marine use to make a direct connection to the negative bus bar or negative ground distribution system. Do not attempt to ground the amplifier using the mounting screws.
• Use fused marine grade battery wire (sold separately) of adequate gauge that has been properly terminated for marine use to make a direct connection to the positive bus bar or positive distribution system. If the screw for the ground wire loosens or falls out, it could result in fire, smake nr malfunction
• Always use a fuse of the rating prescribed.  The use of an improper fuse could result in overheating and smoke damage to the product, and injury, including burns. Check all electrical and signal connections (power, ground, amplifier, speaker, etc.) if amplifier fuse or battery wire fuse blows. Resolve any loose or short-circuited connections, then replace the blown fuse with an identical value equivalent.
• Always install the amplifier on an even surface. Do not install the amplifier on a surface that is uneven or has a protrusion. Doing so could result in malfunction.
• When installing the amplifier, do not allow parts such as extra screws to get caught between the amplifier and the boat. Doing so could cause malfunction.
• In the event of any abnormality, the power supply to the amplifier may cut off to pre-vent equipment malfunction. If this occurs, switch the system power off and check all electrical and signal connections (power, ground, amplifier, speaker, etc.) for loose or short circuited connections. If you are unable to determine the cause, please contact your dealer.

Always disconnect the negative terminal of the battery before making any electrical or signal connections to avoid the risk of electric shock or short circuit during installation.

Do not attempt to disassemble or modify this unit. Doing so may result in fire, electric shock or other malfunction. Damage or defects resulting from alterations or modifica-tions not authorized in writing by Pioneer are excluded from limited warranty coverage.

1. Do not install the amplifier in a location exposed to direct sunlight or excessive heat, humidity or dust.
2. While this amplifier is designed to be water-resistant, it should never be submerged underwater or subjected to high-pressure water spray.
3. Install the amplifier in a dry and well-ventilated environment, where other equipment will not interfere with it.
4. When drilling holes in the chassis for installation location, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring. Failure to take such precautions may result in fire.
5. To ensure proper heat dissipation of the amplifier, ensure the following during installation:
6. Allow adequate space above the amplifier for proper ventilation.
7. Do not mount the amplifier in the engine compartment or in any areas of extreme heat.
8. Do not cover the amplifier.

Ask your dealer or installation professional to install/uninstall this product. Incorrect installation can create dangerous hazards or interfere with boat operation. Keep small items such as bolts, screws and tools out of the reach of children. Swallowing can cause serious injury. If swallowed, con-sult a doctor immediately.

CAUTION

• Always keep the volume low enough to hear outside sounds.
• Extended use of the amplifier while the engine is at rest or idling may exhaust the battery.
• The graphical symbol placed on the product means this is an electronic product requiring direct current electrical power.

About the protection function

This product has a protection function. If this product detects something abnormal, the Power/Protect indicator will turn red and the operation of amplifier will be stopped.
Possible causes include:

• When the temperature inside the product becomes high
• When speaker output detects an abnormality
• When the supply voltage is out of specification

Important (Serial number)

The serial number is located on the bottom of this unit. Be sure to record this number on the enclosed warranty card before installation.

Setting the unit What’s what Top side

• Use the supplied wrench to remove the four screws and detach the top panel cover. Be sure not to lose the removed screws.

• Use a flathead screwdriver to adjust the switch if needed.

Right side

SPEAKER SETTING switch

Switch the output power according to the connected speaker. When a subwoofer is connected, select MONO. When a full-range speaker is connected, select 2CH.

GAIN volume

Adjusting gain volume CH A (channel A) and CH B (channel B) helps align the head unit output to the Pioneer amplifier. Default setting is the NOR (normal) position.
If the output remains low even when the head unit volume is turned up, turn the volume to a lower level (clockwise). If distortion occurs when the head unit volume is turned up, turn these volumes to a higher level (counterclockwise). If using only one input plug, set the gain volumes for speaker outputs A and B to the same position. For use with an RCA-equipped stereo (standard output of 500 mV), set to the NOR (normal) position. For use with an RCA-equipped Pioneer head unit with a maximum output of 4 V or more, adjust level to match that of the stereo output. For use with an RCA equipped head unit with output of 4 V, set to the H (High) position.

FREQ (Hz) cutoff frequency

The cutoff frequency is selectable from 50 Hz to 500 Hz when the LPF/HPF select switch is set to either LPF or HPF. For more information, refer to the Precise Frequency Selection Chart.

LPF (low-pass filter)/HPF (high-pass filter) select switch

The settings based on the connected speaker.
When a subwoofer is connected: Select LPF. This eliminates high-range frequencies and limits output to only low-range frequencies. When a full-range speaker is connected:  Select HPF or OFF. HPF eliminates low-range frequencies and limits output to only high frequencies. OFF bypasses the LPF/HPF and outputs all frequencies.

INPUT SENS switch

Select RCA for RCA level input signals or SP (Speaker) for Speaker level input signals.

INPUT SELECT switch

Select 2CH for two-channel input or 4CH for four-channel input.

Power/Protect indicator

The power indicator lights blue to indicate power ON. The power indicator lights red to indicate protection mode has been engaged.

Setting gain properly
A protective function is included to avoid malfunction of the unit and/or speakers due to excessive output, improper use or improper connection. When outputting high volume sound etc., this function may cut off the output for a few seconds as a normal function. Output will be restored when the volume of the headunit is turned down. A cut in sound output may indicate the improper setting of the gain volume. To ensure a continuous sound output with the head unit at a high volume, set the amplifier gain volume to a level appropriate for the preout maximum output level of the headunit, so that volume can remain unchanged and to avoid distortion caused by signal waveform clipping at the amplifier input  Even with the correct volume and gain settings, the unit sound may cut out periodically. In such cases, please contact an authorized Pioneer Service Company.

Gain volume of this unit

0.5 V (Maximum preout level=2 V) Maximum preout level=4V

Above illustration shows NOR (normal) gain setting.
Relationship between amplifier gain and head unit output power.

If amplifier gain is raised improperly, this will simply increase distortion, with little increase in power.

Signal waveform when outputting high volume using amplifier gain volume

If the signal waveform is distorted due to high output, even if the amplifier gain is raised, the output power will change only slightly.

Before connecting the amplifier

WARNING

• Secure the wiring with cable clamps or adhesive tape. To protect the wiring, wrap sections in contact with metal parts in adhesive tape.
• Never cut the insulation of the power supply to feed power to other equipment. The current capacity of the wire is limited.

CAUTION
If the system remote control wire of the amplifier is connected to the power terminal via the ignition switch (12 V DC), the amplifier will remain on with the ignition whether the headunit is on or off, which may exhaust the battery if the engine is at rest or idling. Install and route the separately sold marine-grade battery wire, marine-grade ground wire, speaker wires and the amplifier as far away as possible from the radio antenna, antenna cable, tuner and any communications equipment and wiring.

The point of connector attachment/detachment

• Push in the connector until a clicking sound is heard, confirming a secure connection.
• How to remove the connector:

1.  Insert the supplied tool into the lock part of the connector.
2. Gently raise the release locking tab to separate the connector.

Note: Attempting to remove the connector by force or pulling from the wire harness can cause damage. To avoid injury, use a work glove to help with gripping the tool.

If you lose the supplied tool, use a flat screwdriver with a tip width of 3 mm or less as a substitute.

About suitable specification of speaker

Regarding the speaker to be connected to the amplifier, use a speaker having a rated input capac-ity more than the rated output capacity of the amplifier. If this condition is not met, there is a risk

If the function still does not work, please use a system remote control wire (sold separately). If multiple amplifiers are to be connected together synchronously, connect the headunit and all amplifiers via the system remote control wire.

Installation

Before installing the Amplifier

WARNING

• To ensure proper installation, use the supplied parts in the manner specified. If any parts other than those supplied are used, they may damage internal parts of the amplifier  or become loose, causing the amplifier to shut down.
• Do not install — On surfaces that could become loose if the boat stops suddenly (chassis recommended).
  • — In places where it may interfere with the boat’s operation.
• Install tapping screws in such a way that the screw tip does not touch any wire. This is important to prevent wires from being cut by vibration of the boat, which can result in fire.
• Make sure that wires do not get caught in the sliding mechanism or touch the legs of a person in the boat as short-circuit may result.
