Customizable Controls over three separate audio zones:

• Variable: The volume knob adjusts all zones simultaneously, with independent control of each zone’s relative offset level.
• Fixed: Sets the output level of selected zones at a specific output voltage (4V, 2V or 1V RMS) that is not affected by the volume control.
• Off: Disables the output level of selected zones.
• Volume Limit: Allows you to set a custom, maximum, allowable volume level for each zone.
• Rename Zone: Permits the creation of custom names for each zone, or choose from a list or preset vessel location names.
• Name this Device: Give your MediaMaster® a custom-name to easily recognize it on paired Bluetooth® devices and connected MFDs.
• Independently adjustable offset volume level for each zone
• Subwoofer zone’s level and tone controls can be linked or set to proportionally track (follow) Zone 1 or 2 or disabled.

Tone Control Mode options allow customization of treble, midrange bass and balance settings as:

• Same as Zone 1: Links the controls with Zone 1.
• Independent Tone Control: Permits distinct tone control adjustments for the selected zone.
