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 blar

ing or distortion and, most importantly, with- out affecting your sensitive hearing. Sound

an 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 amplier 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 con-nect the ground wire first. Ensure that the round 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 loos ens or falls out, it could result in re, 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 prod uct, 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 connec tions, then replace the blown fuse with an dentical value equivalent. Always install the amplifier on an even sur face. Do not install the amplifier on a surface hat 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, witch 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.

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. 2 GAIN volume Adjusting gain volume CH A (channel A) and CH B (channel B) helps align the headunit output to the Pioneer ampli

fier. Default setting is the NO R (normal) position. If the output remains low even when the headunit volume is turned up, turn the volume to a lower level (clockwise). If dis

tortion occurs when the headunit volume is

urned 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 headunit with maximum output of 4 V or more, adjust level to match that of the stereo output. For use with an RCA equipped headunit 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. 4 LPF (low-pass lter)/HPF (high-pass lter) select switch

witch the settings based on the con- nected speaker.

When a subwoofer is connected: Select L PF. This eliminates high range frequencies and limits output to only low range frequencies. When a full range speaker is connected: Select H PF or OFF. HPF eliminates low range frequencies and limits output to only high frequencies. OFF bypasses the LPF/HPF and outputs all frequencies. 5 INPUT SENS switch Select RCA for RCA level input signals or SP (Speaker) for Speaker level input signals. 6 INPUT SELECT switch Select 2CH for two-channel input or 4CH for four–channel input. 7 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 improper setting of the gain volume. To ensure continuous sound output with the headunit at a high volume, set the ampli

fier gain volume to a level appropriate

or 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 correct volume and gain set

tings, the unit sound may cut out period- ically. In such cases, please contact an

uthorized Pioneer Service Company. Gain volume of this unit

Above illustration shows NOR (normal) gain setting. Relationship between amplier 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 amplier 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 amplier WARNING Secure the wiring with cable clamps or adhe- sive 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. 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 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 equip-ment 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.

When the headunit is turned off, the amplifier turns off automatically. This function may not work with some headunits. In such cases, make sure that the front chan- nel is connected correctly. 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 amplier WARNING To ensure proper installation, use the sup- plied 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. 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. Example of installation on the chassis 1 Place the amplier in the desired installation location. Insert the supplied tapping screws (4 mm × 25 mm) into the screw holes and push on the screws with a screwdriver so they make an imprint where the installation holes are to be located. 2 Drill 2.5 mm (1/8 in.) diameter holes in the mounting surface. 3 Install the amplier with the use of supplied tapping screws (4 mm × 25 mm).
