1. PRECAUTIONS

1. This unit does not operate independently . The
unit must be used with a source unit that has
a cable connection for CeNET wire bound
(sold separately).

2. The DPH7500z can easily be damaged by
moisture, high temperatures or high humid­ity. Keep the inside of the car clean and well
ventilated.

3.

Never subject the DPH7500z to strong shocks or
open its case. Doing so may result in damage.

This equipment has been tested and found to
comply with the limits for a Class B digital de­vice, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable
protection against harmful interference in a resi­dential installation. This equipment generates,
uses, and can radiate radio frequency energy
and, if not installed and used in accordance with
the instructions, may cause harmful interference
to radio communications. However, there is no
guarantee that interference will not occur in a
particular installation. If this equipment does
cause harmful interference to radio or television
reception, which can be determined by turning
the equipment off and on, the user is encour­aged to consult the dealer or an experienced ra­dio/TV technician for help.

4. FUNCTIONS OF DPH7500z

With the DPH7500z, you can enjoy the DSP and
equalizer effects by simulating the sound field
using the easy menu with simple operation (easy
mode), and also by simulating the sound field by
adjusting the sound according to the width of the
car interior (professional mode).

• Choose either easy mode or professional mode
to adjust the sound field and sound quality.

• The following major functions are available on
the DPH7500z:

Functions common to each mode

Spectrum analyzer display, auto loudness, etc.

Easy mode

Graphic equalizer function, DSP function, etc.

Professional mode

Space equalizer function, parametric equalizer
function, etc.

• In this manual, graphic equalizer is hereafter
referred to as G.EQ, space equalizer referred
to as S.EQ, and parametric equalizer referred
to as P.EQ.

Functions common to each mode

7-band spectrum analyzer display

Spectrum analyzer display of 7 bands is possible.

Auto Loudness Adjustments

You can vary the amount of compression be­tween 0 and 10 without changing the loudness.

Subwoofer Adjustments

The following adjustments can be made if a
subwoofer is connected:

1. You can set the speakers to:

“OFF”, “MONO” and “STEREO”.

2. You can set the subwoofer volume to:

0 to 14

3. You can set the low-pass filter frequency to:

50Hz, 80Hz or 120Hz.

∗ The slope of the low-pass filter is 24dB/oct.

Test-tone Output

T est tones can be output in the f ollowing order to
check the speaker connections:

FRONT-LEFT ➜ FRONT-RIGHT ➜ REAR-LEFT ➜
REAR-RIGHT ➜ WOOFER-LEFT ➜ WOOFER­RIGHT ➜ ALL(all speakers) ➜ OFF(no sound)

Title Input

You can assign and display titles for the DSP,
G.EQ, S.EQ and P.EQ settings you have set.

4V preout

The preout voltage is raised to 4 V, providing char­acteristics that are resistant to noise during sig­nal transmission.

Note:

• Since noise or sound distortion may occur when
an external amplifier is connected to this unit, keep
the amplifier gain at a lower level.

Digital signal input terminal

Since 4 digital input signal terminals are provided
with this unit, up to 2 units with digital signal out­put terminals (such as a CD changer) can be
connected.

Notes:

• When the DPH7500z and a unit with digital signal
output terminal are connected with the digital op­tical fiber cable, and the digital optical fiber cable
is disconnected, no sound is heard. Reconnect the
digital optical fiber cable.

• If you want to listen to music from an analogue
input, disconnect the digital optical fiber cable and
perform a system check by operating the source
unit.

High-pass Adjustments

You can select the frequency of the high-pass
filter from Through, 50Hz, 80Hz and 120Hz.

∗ The slope of the high-pass filter is 18dB/oct.

flected sound.

INITIAL DELAY: Adjusts the distance between

sound source and reflecting
surfaces.

REAR MIX: Adjusts the ratio of the direct

sound output from the rear

speaker.
REVERB TIME: Adjusts reverberation length.
ROOM SIZE: Adjusts expansion.
HIGH: Adjusts the percentage of high

frequencies in reverberations.
LIVENESS: The sense of the room’s dy-

namics can be adjusted.

• The settings for the basic DSP menus and the

adjustment ranges are shown in the following
table.

About the sound field system

The DPH7500z divides the sound field into three
systems: reverberation, early-reflection and
B.G.M. The reverberation system is the part of
the sound field where reverberating sound is
vivid, while the early-reflection system is the part
of the sound field where reflected sound is em­phasized.

• DSP menus for the reverberation system:
HALL, CHURCH, DOME, CHAMBER

• DSP menus for the early-reflection system:
STADIUM, LIVEHOUSE, DISCO, JAZZCLUB,
P ARK, THEATER, STUDIO

• DSP menus for the B.G.M system:
B.G.M

Notes:

• There are some parameters that cannot be ad­justed, depending on the sound field system.

• The reverberation system cannot adjust ROOM
SIZE and LIVENESS parameters.

• The early-reflection system cannot adjust RE­VERB TIME and HIGH parameters.

• The B.G.M system can adjust only the EFFECT
parameter.

DSP memory

You can store 6 sound fields into the memor y
which, are edited on the basis of the basic DSP
menus.
