Installation precautions
Before you drill or cut any holes, investigate your vessel’s layout very carefully.
Take special care when you work near the gas tank, fuel lines, hydraulic lines
and electrical wiring.
Never operate the amplifier when it is unmouned. Attach all audio system
components securely within the amplifier to prevent damage, especially in an
accident.
Do not mount this amplifier so that wire connections are unprotected. in a
pinched condition, in contact with any metal surfaces in your marine vessel,
or likely to be damaged by nearby objects.
Before making or breaking power connections in your system, disconnect the
marine vessel battey. Confitm that your heaf unit or other equipment is turned
off whine connecting the input jacks and speaker terminals.
If you need to teplace the power fuse, replace it only with a fuse idenetical to that
supplied with the amplifier, Using a fuse of a different type or rating may result
in damage to your audio system or your amplifier which is not covered by the
manufactuer’s warrany.
Don’t misuse the level control!
Do not mistake the input level control for a volume control! It is designed
ONLY to match the output level of your audio source to the input level of
your amplifier.
Do not adjust this input level of maximum unless your input level requires it.
Ignoring these instructions will result in an input overload to the amplifier,
and excessive audio distortion. It can also cause the protection circuit to
engage.

The switches and gain settings are located behind a watertight pulg, which
also lights up when the amplifier is on. Be sure to replace the plug when
finished with adjustments
1
The INPUT LEVEL switch selects the input sensitivity of the amplifier. If
you are connecting to a LINE level source (typically any RCA type
connection) then the switch should be in the LINE (out) position. When
connecting to loudspeaker outputs or headphone or high level sources
then set the switch to the SPEAKER (in) position.
2
The POLARITY switch allows the user to optimize bass performance in
the case that there are more than 1 set of loudspeakers producing bass
in the system. Play some music with strong bass content and listen with
the switch alternately in the NORMAL and REVERSE position until it can
be determined which setting results in more pleasing bass response. If
in doubt, or if any interaction with other speakers is unlikely, then leave
the switch in the NORMAL position.
3
The GAIN control adjusts the overall level of the amplifier. When using
the amplifier without volume control the level should beset to achieve a
balance with other loudspeakers in the system. As arule, keep the gain
setting as low as possible while still insuring that thesystem will reach
full output power. When using the system with external volume control,
set the external Volume Control to FULL (clockwise) and adjust the gain
on the amplifier until full output power is reached. Full output power level
can be determined by turning the gain control clockwise until the apparent
loudness does not appear to increase any more. Leave the control at the
setting where this begins to become apparent.
