Alpine IVA-W502E Parametric Equalizer Adjustments, Setting the Speakers, Setting of Dolby Digital

Parametric Equalizer Adjustments

The frequency bands of the graphic equalizer are fixed. This makes it very difficult to correct for undesired peaks and dips at specific frequencies. The parametric equalizer’s centre frequency can be tuned to these specific frequencies. Then, the bandwidth (Q) and level are fine-tuned, independently, to make the necessary corrections. The parametric equalizer function is an advanced tool for serious audiophiles.

Setting item: P-EQ

•When the speaker is set to the “OFF” mode, the parametric equalizer for that speaker cannot be set. Refer to “Setting the Speakers” (page 44).

•It is not possible to adjust the frequencies of adjacent bands within 7 steps.

•Check the playable frequency ranges of the connected speakers before making the equalizer adjustments. If the speaker’s playable frequency range is 55 Hz to 30 kHz, for example, adjusting the 40 Hz or 20 Hz band has no effect. Additionally, you may overload and damage the speakers.

•When the parametric EQ is adjusted, the adjustment for graphic EQ becomes ineffective.

Setting the Speakers

Setting item: SPEAKER SELECT

Set the connected speaker by touching the respective [ ] or [ ] button.

FRONT1: OFF/FULL (Full Range)/TW (Tweeter)

FRONT2: OFF/ON

REAR: OFF/ON

CENTER: OFF/ON

SUBW.: OFF/MONO/STEREO

•Set the speaker which is not connected to OFF.

•Settings above can be carried out even when the speaker is set to OFF in “Speaker Setup” (page 45).

•To use the subwoofer in MONO with PXA-H700 or PXA-H701 connected, connect the subwoofer to the subwoofer output terminal of PXA-H700 or PXA-H701.

Setting of Dolby Digital

Setting item: MULTI CH SETUP

Adjusting the acoustic image (BI-PHANTOM)

In most installations, the centre speaker must be placed directly between the front passenger and driver. Using this function, the centre channel information is distributed to the left and right speakers. This creates an acoustic image simulating a centre speaker directly in front of each listener. Adjusting the centre width in PL II MUSIC (see “Using the Pro Logic II Mode” on page 42), makes this function ineffective.

•Avoid stopping, pausing, switching the disc, cueing, fast-forwarding or switching the audio channel of this unit while making this adjustment. The setting is cancelled if the Decode mode is switched.

Touch [ ] or [ ] of BI-PHANTOM to adjust the level.

The level can be adjusted within the range of -5 to +5. The higher the level, the more the position of the centre speaker is shifted to the sides.

The BI-PHANTOM function is turned off by touching [OFF].

•This adjustment is effective when the setting of the centre speaker to SMALL or LARGE in the speaker setup settings.

•This adjustment is ineffective when the speaker is set CENTER to OFF in “Setting the Speakers” (page 44).

Mixing bass sound to the rear channel (REAR MIX)

This function mixes the front channel audio signals to the audio signals output from the rear speakers, improving the sound in the vehicle’s rear seat.

•Avoid stopping, pausing, switching the disc, cueing, fast-forwarding or switching the audio channel of this unit while making this adjustment. The setting is cancelled if the Decode mode is switched.

Touch [ ] or [ ] of REAR MIX to adjust the level.

The level can adjusted in five steps: -6, -3, 0, +3 and +6. The higher the level, the more bass is output from the rear speakers. (The effect differs according to the software (DVD, etc.).)

The REAR MIX function is turned off by touching [OFF].

•This adjustment is ineffective when the rear speaker setup setting is set to “OFF”.

•For linear PCM signals, the voice is output from the rear speaker regardless of the REAR FILL and REAR MIX setting.
