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 DPH910 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 DPH910 to strong shocks or open its case. Doing so may result in damage.
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.
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 r e s i d e n t i a l i n s t a l l a t i o n .

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.
Test-tone Output
Test tones can be output in the following order to check the speaker connections:
FRONT-LEFT
➜ FRONT-RIGHT ➜ REAR-LEFT ➜
REAR-RIGHT
➜ WOOFER-LEFT ➜ WOOFER-
RIGHT
➜ ALL(all speakers) ➜ OFF(no sound)
Title Input
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.
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.
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.

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 RE-
VERB TIME and HIGH parameters.
• The B.G.M system can adjust only the EFFECT parameter.

3. Digital Optical Fiber Cable
When you connect the digital optical fiber cable to the digital input terminal or to the digital output terminal, firmly insert it until it is locked in position.
Connect the black slid cap side to the digital input terminal of the DPH 910.
Note:
Do not bend the digital optical fiber cable through a loop smaller than 1˝ (3cm) in radius. Doing so will greatly reduce perfomance.
To remove the digital optical fiber cable, pull it by lightly grasping the slide cap C of the cable in your fingers.
