Controls, Input, and Output Cables

The switches and gain settings are located behind a watertight plug, 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 headphones 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 is 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 positions until it can be determined which setting results in a 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 be beset to achieve a balance with other loudspeakers in the system. As a rule, keep the gain setting as low as possible while still ensuring that the system 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. The full output power level can be determined by turning the gain control clockwise until the apparent loudness does not appear to increase anymore. Leave the control at the setting where this begins to become apparent
4. VOLUME CONTROL Plug for the waterproof remote volume control. When installed, this control will turn off the PLMRMP3A Amp when turned all the way down.
5. INPUT Stereo RCA audio input for connecting other audio devices.

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 unmounted. 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 battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals.
• If you need to replace the power fuse, replace it only with a fuse identical 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 manufacturer’s warranty.

Don’t misuse the level of control!

Do not mistake the input level control for 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 to 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.

FREQUENTLY ASKED QUESTIONS

Do you need an amplifier for marine speakers?

Most marine stereos have an amplifier built in and some of them are surprisingly powerful. It is very possible to get good-quality sound without an external amplifier. For most people, I encourage them to try their stereo without an amplifier first, because you can almost always add an amp later.

What does an amp do for boat speakers?

Amplifiers can handle two speakers per channel, meaning a four-channel amp will allow you to power eight total speakers.

How many channels do I need in marine amplifier?

If you have a smaller boat, or just don't want a massive sound system, a 2-channel amplifier is a practical solution if you only want to power a single pair of speakers. But if you think you might want to add another set of speakers in the future, get a 4-channel amp now, so you'll be ready when the time comes.

Does an amplifier need to be connected to a speaker?

If you have an amplifier with power tubes in the output section, then you cannot operate it without a speaker load connected. Simply put, in the tube amp output section, the transformer performs the task of transforming the speaker load to a load the tubes want to see.

How much power does an audio amplifier need?

If you are mainly doing light dance music or voice, we recommend that the amplifier power be 1.6 times the Continuous Power rating per channel. If you are doing heavy metal/grunge, try 2.5 times the Continuous Power rating per channel.

How much power does a speaker amp use?

The appropriate power amplifier power plan is about 50W-100W. However, there are two variables: “speaker efficiency” and “listening distance”: if the speaker's efficiency is higher than 88dB/w/m or more, only 30W-60W power is enough.

Do amplifiers need electricity?

Amplifiers (and/or preamplifiers) are essential components in most practical audio signal chains and typically require electrical power to function properly. They're used to drive loudspeakers and headphones, boost mic and instrument signals to usable levels, and for many other reasons.

How many watts is 4 ohms?

With a 4-ohm speaker, the maximum output power will be 350 watts.

How do I know if my amplifier is powerful?

A good amplifier uses signal power with maximum efficiency, achieving a high signal-to-noise ratio. That is, the level of the audio signal is significantly higher than the accompanying signal noise. Anything above 100 dB should provide excellent sound quality with minimal distortion and maximal clarity.

Does wattage affect volume?

Yes, it's true that the higher the power (watts), the louder and cleaner the speakers will play. Small differences in power, however, don't make much of an audible change. In order to perceptively hear a difference (a 3dB increase), the power would have to double.

Do amplifiers sound different?

With amps, the sound, as opposed to notes, is the first thing to go. A great amp strips away the artifice of sound reproduction and lets more of the music shine through. Vacuum tube amplifiers measure and sound differently, some say better, and some say worse than solid-state amps, but again they both play the same notes.

What is the common problem of amplifier?

Many things can go wrong with amplifiers, the most common being operator error. That is, if everything lights up but there is no sound, the speaker wires may not be connected or the speaker button may not be selected. Otherwise, the cord may be damaged or an internal fuse may be blown.
