  2. Press and hold the dial.

    The SUB LEVEL adjustment for the zone appears.

  3. Press the dial to select a tone.
  4. Adjust the tone level and press the dial to set it.

    You can drag the slider bar to adjust the tone level.

Disabling the Loud Setting for a Zone

The LOUD setting maintains frequency response at low volumes and increases perceived loudness at high volumes. This setting is enabled by default in all zones.

  1. Select Menu symbol > AUDIO.
  2. Select a zone to adjust.
  3. Select LOUD to clear the check box.

Adjusting the Gain for an Auxiliary Device

You can adjust the gain for a connected auxiliary device to achieve a volume level similar to that of other media sources. You can adjust the gain in 1 dB increments. You can also adjust the gain for ARC sources connected using an HDMI® cable.

  1. Select an applicable source.
  2. Select an option:

    • To increase the gain, select Increase the gain symbol.

    • To decrease the gain, select Decrease the gain symbol.

    NOTE: To achieve the best audio quality when using a portable media player with headphone output, it may be necessary to adjust the volume control on the media player, instead of adjusting the gain.

Speaker Zones

You can group speakers in one area into a speaker zone. This enables you to control the audio level of the zones individually. For example, you could make the audio quieter in the cabin and louder on deck.

You can set the balance, volume limit, tone, subwoofer frequency, and name for each zone, and configure other zone-specific settings (Speaker Zone Settings).
NOTE: Subwoofer frequency is not adjustable when managed by DSP.

DSP Settings

This stereo features digital signal processing (DSP). You can select pre-configured DSP settings for Fusion® speakers and amplifiers to optimize audio reproduction in their installed locations.

All DSP settings are configured using the Fusion Audio remote control app (Fusion Audio Wireless Remote Control App).

Configuring the DSP Settings

You must download and install the Fusion Audio remote control app on your compatible Apple® or Android™ device before you can configure the DSP settings (Fusion Audio Wireless Remote Control App).

You can configure the DSP settings to optimize the sound on each zone with the installed speakers, amplifiers, and environment.

  1. From the settings menu on your Apple or Android device, connect to the stereo using Bluetooth® technology or connect to the same wireless network as the stereo.
    NOTE: If you have a compatible Apple device, you can connect a USB sync cable appropriate for your device (sold separately) to the USB port on the stereo and to your Apple device to configure the DSP settings using the Fusion Audio app.
  2. Open the Fusion Audio remote control app on your compatible Apple or Android device.
  3. If necessary, select the stereo you want to configure.
  4. Select Settings symbol.
  5. If necessary, select the MUSIC tab.
  6. Select a zone.
  7. Select DSP SETTINGS.
  8. Configure the DSP settings as needed, depending on the models of Fusion speakers and amplifiers connected to the zone.
  9. Select SEND DSP SETTINGS.
    NOTE: DSP settings or updates for the zone are not applied on the stereo until you select the button to send the settings.
  10. Repeat these steps for each zone.

Automatic Volume Adjustment Based on Speed

If your stereo is connected to a NMEA 2000® network with a device that provides speed information such as an engine, chartplotter, GPS antenna, water speed sensor, or wind speed sensor, you can set the stereo to adjust the volume automatically based on the selected speed source (Enabling Automatic Volume Adjustment Based on Speed).

For example, if a chartplotter with an internal GPS antenna or a stand-alone GPS antenna is on the same NMEA 2000 network as the stereo and you set the SPEED SOURCE to SPEED OVER GROUND, the volume increases as your speed increases.

NOTE: When the volume increases to adjust for speed, the actual volume output changes, but the volume-level indicator bar and number stays the same.

For more information about connecting the stereo to a NMEA 2000 network, see the installation instructions for your stereo.
