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. Use a soft, dry cloth to wipe dirt off the
DPH910. Never use a hard cloth or thinners,
alcohol, etc. For tough dirt, apply some cold
or lukewarm water to a soft cloth and wipe
off the dirt gently.
5. When the source unit is switched to the traffic
announcement or PTY interrupt reception
while using the DPH910, the effect from
DPH910 doesn’t work.
6. Some tracks may sound distorted when
adjusted; this is nomal and not a cause for
concern.

4. FUNCTIONS OF DPH910
With the DPH910, you can enjoy the DSF and
equalizer effects by simulating the sound field
using the easy menu with simple operation (standard mode), and also by simulating the sound
field by adjusting the sound according to the width
of the car interior (professional mode).
• Choose either standard mode or professional
mode to adjust the sound field and sound quality.
• The following major functions are available on
the DPH910:
Functions common to each mode
Spectrum analyzer display, auto loudness, etc.
STD mode
Graphic equalizer function, DSF function, etc.
PRO mode
Virtual Space Enhancer function, parametric
equalizer function, etc.
• In this manual, graphic equalizer is hereafter
referred to as G.EQ, Virtual Space Enhancer
referred to as VSE, 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
Test tones can be output in the following order to
check the speaker connections:
You can assign and display titles for the DSF,
G.EQ, VSE 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 2 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 DPH910 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.

About the sound field system
The DPH910 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.
• DSF menus for the reverberation system:
HALL, CHURCH, DOME, CHAMBER
• DSF menus for the early-reflection system:
STADIUM, LIVEHOUSE, CLUB, JAZZCLUB,
PARK, THEATER, STUDIO
• DSF 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.
