Introductions
The MLS-300 External Loudspeaker is a high performance communications speaker matching the impedance and output requirements of most Standard Horizon transceivers.
INSTALLATION
MOUNTING BRACKET INSTALLATION
- Remove the MLS-300 from the bracket by removing the two Mounting Bracket Knobs.
- Choose a place to mount the MLS-300.
- Use the bracket as a template to mark the locations of the mounting holes.
- Use a 5.2-mm (17/64”) bit to drill the holes, and secure the bracket with the supplied screws, spring washers, flat washers, and nuts (Figure 1 & 2).
- Insert the MLS-300 into the bracket with the Mounting Bracket Knobs which were removed in step 1.
- Set the MLS-300 to the preferred angle, and then tighten the Mounting Bracket Knobs to fasten the MLS-300 to the bracket.
- Route and secure the speaker cable from the MLS-300 to the Marine VHF. Connect the WHITE wire of the speaker cable to the marine VHF’s positive (+) external speaker output and the shield of the speaker cable to the negative (–) external speaker connection.
FLUSH MOUNT INSTALLATION
-
Remove the MLS-300 from the bracket by removing the two Mounting Bracket Knobs, and then remove the rear case of the MLS-300 from the main body by removing the four screws (Figure 3.).
Assemble the supplied M4x50 Screw, Nut, and Washer as the Figure 4. -
Use the supplied template to mark the location where the round hole is to be cut. Confirm the space behind the dash or panel is deep enough to accommodate the MLS-300 (at least 2.8 inch (70 mm) deep).
-
Cut out the round whole (one large hole and four small mounting holes) and inset the MLS-300 from the front side.
-
Referring to Figure 5, pass through the four M4x50 Screws (with Nut and Washer) into the mounting holes on the panel from the back side and turn the M4x50 Screws five times.
-
Turn the four Nuts to adjust the tension so that the MLS- 300 is tight against the mounting surface.
-
Route and secure the speaker cable from the MLS-300 to the Marine VHF. Connect the WHITE wire of the speaker cable to the marine VHF’s positive (+) external speaker output and the shield of the speaker cable to the negative (–) external speaker connection.

Frequently Asked Questions
Do external speakers require electricity?
Every amplifier needs power to operate. Therefore, speakers with built-in amplifiers need power to operate effectively. The audio signal level will need to be increased by an external amplifier for fully passive speakers.
What happened to my external speaker?
Verify that the default output is selected on the external speaker. Make sure the connections are correctly connected and the external speaker is powered. Check for sound by connecting an external speaker or headphone to another device. Hardware-test your machine.
What do speakers on the outside do?
To give the sound more amplification (make it louder), add more bass with a subwoofer, or generate surround sound, external speakers are connected to a computer or another device.
How can I turn on my speakers outside?
Go to the taskbar in Windows. Open Sound Settings & enter Audio Preferences can be chosen by performing a right-click on the speaker icon. Go to Manage Sound Devices from the Output section. Choose the choice after choosing the output device.
How can I link my desktop to external speakers?
Locate your computer’s sound card jacks. If necessary, connect one speaker to the other. Connect the speaker cord to the computer’s green “Line-out” jack. Turn on the speakers by inserting the power line from the speakers into an electrical outlet.
