Alpine 68-21627Z10-A Equalizer Presets F-EQ CDE-HD137BT Only, Setting EQ mode CDE-HD138BT Only

Equalizer Presets (F-EQ)

(CDE-HD137BT Only)

10 typical equalizer settings are preset at the factory for a variety of musical source material.

Setting item: FACTORY EQ

Setting contents:

USER / FLAT (Initial setting) / POPS / ROCK / NEWS / JAZZ /

ELEC DANCE / HIP HOP / EASY LIS / COUNTRY / CLASSICAL

Turning Loudness On/Off

(CDE-HD137BT Only)

Loudness introduces a special low-and high-frequency emphasis at low listening levels. This compensates for the ear’s decreased sensitivity to bass and treble sound.

Setting item: LOUDNESS

Setting contents:

OFF (Initial setting) / ON

Setting EQ mode (CDE-HD138BT Only)

This setting gives you a choice of 5-band parametric, or 7-band graphic equalizer.

Setting item: EQ MODE

Setting contents:

5BAND P.EQ (Initial setting) / 7BAND G.EQ

5BAND P.EQ:

5-band Parametric EQ.

7BAND G.EQ:

7-band Graphic EQ.

Adjusting the Parametric Equalizer Curve (5BAND P.EQ) (CDE-HD138BT Only)

The Parametric EQ function gives more flexibility than the Graphic EQ in covering problem areas in the vehicles response curve.

You can modify the Equalizer settings to create a response curve more appealing to your personal taste.

1Turn the Rotary encoder to select the Band, and then press ENTER.

BAND1 BAND2 BAND3 BAND4 BAND5

2Turn the Rotary encoder to select the desired item, and then press ENTER.

Setting the Bandwidth (WIDTH (Q))

3-1Turn the Rotary encoder to select the desired bandwidth.

WIDE 1 (Initial setting) MEDIUM 2 MEDIUM 3 NARROW 4

Change the boosted bandwidth to wide or narrow. A wider setting will boost a wide range of frequencies above and below the center frequency. A narrower setting will boost only frequencies near the center frequency.

Setting the Center Frequency (CENTER FRQ)

3-2Turn the Rotary encoder to select the desired center frequency.

BAND1: 63/80/100/200 (63 Hz)

BAND2: 160/250/400/630/1.0 K (160 Hz)

BAND3: 630/1.0 K/1.6 K/2.5 K/4.0 K (630 Hz)

BAND4: 1.6 K/2.5 K/4 K/6.3 K/10.0 K (1.6 KHz)

BAND5: 10.0 K/12.5 K/16 K/17.5 K (10.0 KHz)

Setting the Level

3-3Turn the Rotary encoder to select the desired level (−6 ~ +6).

4Repeat steps 1 to 3 to adjust other Bands.

Notes

•Press to return to the previous step.

•The frequency range of adjacent bands should not overlap.

•While adjusting the Parametric EQ, you should consider the frequency response of the connected speakers.

•Using the Parametric EQ disables the Graphic EQ function.

Adjusting the Graphic Equalizer Curve (7BAND G.EQ) (CDE-HD138BT Only)

The Graphic EQ is simpler to set up and use compared to the Parametric EQ.

You can modify the equalizer settings to create a response curve more appealing to your personal taste.

1Turn the Rotary encoder to select the desired band, and then press ENTER.

BAND1 80 BAND2 250 BAND3 500 BAND4 1.0 K  BAND5 4.0 K BAND6 8.0 K BAND7 16.0 K

2Turn the Rotary encoder to select the desired level (−6 ~ +6), and then press ENTER.

3Repeat steps 1 to 2 to adjust other Bands.

Notes

•Press to return to the previous step.

•Using the Graphic EQ disables the Parametric EQ function.
