Sony CDX-GT470UM Car Radio

Subwoofer connection

NOTICE: You have to switch the device OFF to set this:

  • GENERAL
    • REAR/SUB
      • SUB-OUT: Send the subwoofer signal directly to a subwoofer.
      • REAR-OUT: Send the subwoofer signal to a power amplifier.

Sound position

Add some sound delay to each channel to simulate a natural sound field based on the listening position. Set the F/R POSITION according to your preferred listening position; for two people in the front seats, FRONT should be selected:

  • SOUND
    • POSITION
      • SET F/R POSITION
        • FRONT L, FRONT R, FRONT, ALL, OFF

High Pass Filter

If you have a subwoofer or you are using the rear spakers as subwoofer (or simply if your audio environment needs to cut some of the low frequencies), it is possible to enable an high-pass filter for the front and the rear speakers.

  • SOUND
    • HPF
      • HPF FREQ: High-pass filter cut-off frequency.
        • OFF, 50Hz, 60Hz, 80Hz, 100Hz, 120Hz
      • HPF SLOP: Slope of the high-pass filter (steepness of the frequency cutoff curve).
        • 1, 2 or 3

Use the rear speakers as subwoofer (Rear Bass Enhancer)

It is possibile to simulate the function of a subwoofer using the rear speakers. It is possible to select the cut-off frequency of the sound to be sent to the rear speakers and the steepness (slope) of the cut-off curve.

NOTICE: Set the subwoofer connection to REAR-OUT before.

  • SOUND
    • RB ENH
      • RBE MODE
        • 1, 2, 3 or OFF
      • LPF FREQ
        • 50Hz, 60Hz, 80Hz, 100Hz or 120Hz
      • LPF SLOP (an higher slope means a more drastic cut-off)
        • 1, 2 or 3

Alternative Frequencies restricted to the same region

When the Alternative Frequencies option is enabled, the radio retunes the station to the strongest signal (it uses RDS to find stations of the same network). By default the searching is restricted to the same region, but you can disable this restriction.

NOTICE: You have to tune an FM radio station to set this:

  • GENERAL
    • REGIONAL
      • OFF

DM+ ON

AUX VOLUME

If the volume of your AUX source is too different from e.g. the TUNER source, it is possible to adjust its volume, increasing or decreasing it.

NOTICE: Set the radio to the AUX source to set this.

  • SOUND
    • AUX VOL
      • dB
