The Safety of Your Ears is in Your Hands
Get the most out of your equipment by playing it at a safe levela 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 leveladapts to higher volumes of sound, so what sounds normalcan 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
cant hear whats 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.

1 FREQ (cut off frequency) control
Cut off frequency selectable from 40 Hz to 500 Hz if the LPF/HPF select switch is set to LPF or HPF.
2 GAIN (gain) control
Adjusting gain controls CHANNEL A (chan­nel A) and CHANNEL B (channel B) helps align the stereo output to the Pioneer ampli­fier. Default setting is the NORMAL posi­tion. If the output remains low, even when the stereo volume is turned up, turn the con­trols to a lower level. If distortion occurs when the stereo volume is turned up, turn these controls to a higher level. ! If using only one input plug, set the gain
controls 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 NORMAL position. For use with an RCA equipped Pioneer stereo, with maximum output of 4 V or more, adjust level to match that of the stereo output.
! For use with an RCA equipped stereo
with output of 4 V, set to the H position.

3 LPF (low-pass filter)/HPF (high-pass fil­ter) select switch
Switch the settings based on the connected speaker. ! When the Subwoofer is connected:
Select LPF. This eliminates high range frequency and outputs low range fre­quency.
! When the full range speaker is con-
nected: Select HPF or OFF. HPF eliminates low range frequency and output high range frequency. OFF outputs the entire fre­quency range.
4 INPUT SELECT (input select) switch
Select 2CH for two-channel input and 4CH for four–channel input.
5 POWER/PROTECT indicator
The power indicator lights up to indicate power ON. ! If something is not normal, the indicator
turns red.
Setting gain properly
! Protective function included to prevent
malfunction of the unit and/or speakers due to excessive output, improper use or improper connection.
! When outputting high volume sound etc.,
this function cuts off the output for a few seconds as a normal function, but output is restored when the volume of the head unit is turned down.
! A cut in sound output may indicate impro-
per setting of the gain control. To ensure continuous sound output with the head unit at a high volume, set amplifier gain control to a level appropriate for the preout maximum output level of the head unit, so that volume can remain unchanged and to control excess output.
! Despite correct volume and gain settings,
the unit sound still cuts out periodically. In such cases, please contact the nearest authorized Pioneer Service Station.
Gain control of this unit
Preout level: 2 V (Standard: 500 mV)
Preout level: 4 V
Above illustration shows 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 at high volume using amplifier gain control
If the signal waveform is distorted due to high output, even if the amplifier gain is raised, the output power will change only slightly.

Notes
! If speaker input wires from a headunit are
connected to this amplifier, the amplifier will automatically turn on when the headunit is turned on. When the headunit is turned off, the amplifier turns off automatically. This function may not work with some headunits. In such cases, please use a system remote control wire (sold separately). If multiple am­plifiers are to be connected together synchro­nously, connect the head unit and all amplifiers via the system remote control wire.
! This amplifier automatically selects an input
signal mode between the RCA level and the speaker level by detecting an input signal.
Solderless terminal connections
! Since the wire may become loose over
time, it must be periodically inspected and tightened as necessary.
! Do not solder or bind the ends of the
twisted wires.
! Fasten while making sure to not to clamp
the insulating sheath of the wire.
! Use the supplied hexagonal wrench to
tighten and loosen the terminal screw of the amplifier and use it to securely fasten the wire. Be careful to avoid excessive tigh­tening of this screw, which may damage the wire.
Connecting the power terminal
WARNING
If the battery wire is not securely fixed to the term­inal using the terminal screws, there is a risk of overheating, malfunction and injury, including minor burns.
! Always use the recommended battery and
ground wire, which is sold separately. Con­nect the battery wire directly to the boat battery positive (+) terminal and the ground wire to the boat body.
! Recommended wires size (AWG: American
Wire Gauge) is as follows. The battery wire, the ground wire and the optional direct ground wire must be same size.
! Use a wire of 12 AWG to 16 AWG wire for
the speaker wire.
1 Route battery wire from engine com­partment to the boat interior.
! When drilling a cable pass-thru into a bulk
head or barrier wall, route the cable through carefully and seal the hole to pre­vent fumes from seeping from engine com­partment to other areas.
After completing all other amplifier connec­tions, finally connect the battery wire terminal of the amplifier to the positive + battery term­inal.

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 in:
Places where injury could occur if the boat
stops suddenly.
Places where it may interfere with the
boat's operator.
! 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.
! When drilling to install the amplifier, always
confirm no parts are behind the panel and protect all cables and important equipment (e.g. cables, wiring, hoses, and modules) from damage.
CAUTION
! To ensure proper heat dissipation of the ampli-
fier, ensure the following during installation: Allow adequate space above the amplifier
for proper ventilation.
Do not cover the amplifier.
! Place all cables away from hot places, such
as near the heater outlet.
! The optimal installation location differs de-
pending on the boat model. Secure the ampli­fier at a sufficiently rigid location.
! Check all connections and systems before
final installation.
