Using the Road Equalizer function

Road Equalizer (REAL-TIME OPTIMIZED ADAPTIVE DRIVING EQUALIZER) is a function that automatically adjusts the equalizer settings during driving according to the amount of road noise.

To use Road Equalizer, first connect the microphone. (See “Preparations for automatic adjustments” on page 12.)

When used in combination with a separately sold monitor that is Road EQ compatible, the monitor’s built-in microphone can be used, in which case the microphone included with the PXI- H990 cannot be used. When connecting two PXI-H990 units, the built-in microphone in the separately sold monitor cannot be used.

Perform the Road Equalizer operations in the following order:

•In order to avoid the effects of exterior noises during measurement of frequency response inside the vehicle, move the car to a quiet location and change the ignition switch to the ACC position.

Due to vibration, correct measurement data may not be acquired, so do not switch on the engine. However, be aware that the battery may be drained.

•Do not remove the microphones when using Road Equalizer.
