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, without 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 the amplifier

WARNING

• To prevent fire hazards, 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 negative ground circuit of the boat. Use adequate gauge, the 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, smoke, or 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 the 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 be cut off to prevent 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 modifications not authorized in writing by Pioneer are excluded from limited warranty coverage.

• Do not install the amplifier in a location exposed to direct sunlight or excessive heat, humidity, or dust.

• While this amplifier is designed to be water-resistant, it should never be submerged underwater or subjected to high-pressure water spray.

• Install the amplifier in a dry and well-ventilated environment, where other equipment will not interfere with it.

• When drilling holes in the chassis for installation, 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.

• To ensure proper heat dissipation of the amplifier, ensure the following during installation:
  — Allow adequate space above the amplifier for proper ventilation.
  — Do not mount the amplifier in the engine compartment or in any areas of extreme heat.
  — Do not cover the amplifier.

• Ask your dealer or installation professional to install/uninstall this prod 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, consult 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.

• One or more subwoofers may be connected to this amplifier, but must meet one of the following configurations:
  — Combined or singular nominal input power handling of 300W or greater if the combined or singular nominal impedance is equal to or greater than 2Ω.

• WARNING: If the nominal input and impedance are not within the above ranges, the subwoofer(s) may catch

Setting the unit

What’s what
Topside

• 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

1. INPUT SENS switch
   Select RCA for RCA level input signals or SP for Speaker level input signals.

2. GAIN volume
   • If the output remains low even when the headunit volume is turned up, turn the volume to a lower level (clockwise). If distortion occurs when the headunit volume is turned up, turn these volumes to a higher level (counterclockwise).
   • 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 headunit with a maximum output of 4 V or more, adjust the level to match that of the stereo output.
   • For use with an RCA equipped headunit with the output of 4 V, set to the H (High) position.
   • If you hear too much noise when using the speaker input terminals, turn the gain control to a higher level.

3. FREQ (Hz) (cutoff frequency)
   You can select a cutoff frequency from 25 Hz to 240 Hz. For precise frequency information, refer to Precise Frequency Selection Chart.

4. BASS BOOST switch
   You can select a bass boost level of 0 dB, 6 dB, or 12 dB.

5. 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. The 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 headunit at a high volume, set the amplifier gain volume to a level appropriate for the preset maximum output level of the headunit, so that volume can remain unchanged and 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.

The gain volume of this unit

Maximum pre-out level=4V
Above illustration shows NOR (normal) gain setting.

Relationship between amplifier gain and headunit output power

If amplifier gain is raised improperly, this will simply increase distortion, with little increase in power.
Signal waveform when outputting at 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.

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 the 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.

CAUTION

• Place all cables away from hot places, such as near the heater outlet.
  The optimal installation location differs depending on the boat model. Secure the amplifier at a sufficiently rigid location.

• Check all connections and systems before final installation.
