Automatic Volume Control Settings
Select
> SETTINGS, select the name of the stereo, then select ZONE > SPEED VS VOLUME.
ENABLED: Enables the automatic volume control feature.
SPEED SOURCE: Sets the source that the stereo uses to determine the speed (
).
MAX/MIN SPEED: Sets the expected maximum and minimum speed range for the selected SPEED SOURCE.
The MIN setting indicates the speed at which the volume plays at the level you set by turning the dial. The
MAX setting indicates the speed at which the volume plays at the highest level set in the VOLUME INCREASE
setting.
TIP: You should start by setting these values at the speeds you typically expect from your engine or sensor
and adjust them as needed.
VOLUME INCREASE: Sets the total volume increase for each zone when the selected SPEED SOURCE reaches
the set maximum speed set in the MAX/MIN SPEED setting. The higher you set this level, the louder the
volume will be as you approach the set maximum speed.
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.
CUSTOM UNITS: Changes the measurement unit used to indicate the vessel or wind speed.
Speed Source Information
Select
> SETTINGS, select the name of the stereo, then select ZONE > SPEED VS VOLUME > SPEED
SOURCE.
ENGINE SPEED: Uses the RPM reading provided by a supported NMEA 2000 engine. The volume increases as
the engine RPM increases from the set MIN speed to the set MAX speed. If multiple supported engines are
connected, the stereo uses the average RPM reading from all engines.
SPEED OVER GROUND: Uses the speed over ground (SOG) reading provided by a supported NMEA 2000 GPS
antenna or chartplotter with an internal GPS antenna. The volume increases as the SOG increases from the
set MIN speed to the set MAX speed.
SPEED THROUGH WATER: Uses the speed through water (STW) reading provided by a supported NMEA 2000
water-speed sensor. The volume increases as the STW increases from the set MIN speed to the set MAX
speed.
WIND SPEED: Uses the wind speed reading provided by a supported NMEA 2000 wind-speed sensor. The
volume increases as the wind speed increases from the set MIN speed to the set MAX speed.
Disabling a Zone
You can disable an unused zone and remove it from the audio level pages. When a zone is disabled, you cannot
change any of the settings for that zone. You cannot disable zone 1.
