User manual CLARION DPH910 INSTALLATION MANUAL

[. . . ] Owner's manual Mode d'emploi Manual de instrucciones Thank you for purchasing the Clarion DPH910. Please read this owner's manual in its entirety before operating this equipment. Check the contents of the enclosed warranty card and keep it carefully with this manual. The operating instructions are not provided with this manual. [. . . ] The following 6 listening positions are available: FULL SEAT, FRONT-RIGHT, FRONT-LEFT, FRONT, REAR and PASS. Fine-tuning the Listening Position The time taken for the sound to leave the speaker and reach you can be fine-tuned to create a natural sound field, no matter where you are sitting in the car. Selection of the sound field (DSF) menus 12 basic DSF menus are stored in the DPH910. 6 DPH910 Standard-mode functions <DSF functions> Editing the DSF You can adjust the sound field using the DSF menus as you like. · The DSF parameters and their contents are as follows: EFFECT: Adjusts the percentage of reflected 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. HIGH: Adjusts the percentage of high frequencies in reverberations. LIVENESS: The sense of the room's dynamics can be adjusted. · The settings for the basic DSF menus and the adjustment ranges are shown in the following table. 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. · The different car types and the speaker installation positions are as follows: Vehicle type 1. MIN VAN-2 front: 2WAY rear: Rear parcel 2. WAGON front: 2WAY rear: Beside the luggage 4. MIN VAN front: 2WAY rear: Beside the luggage 6. MIN VAN front: FULL rear: Equivalent to rear door · The settings of the basic P. EQ menus are as follows: BAND 2 2kHz/F, 1/Q, -4dB/G 1. 25kHz/F, 5/Q, 0dB/G 800Hz/F, 3/Q, -4dB/G 125Hz/F, 5/Q, -12dB/G 1kHz/F, 3/Q, -8dB/G 800Hz/F, 1/Q, -8dB/G 500Hz/F, 5/Q, -5dB/G 1. 25kHz/F, 3/Q, -4dB/G 630Hz/F, 3/Q, -4dB/G 1. 25kHz/F, 3/Q, -8dB/G 500Hz/F, 5/Q, -5dB/G BAND 3 5kHz/F, 1/Q, -4dB/G 8kHz/F, 5/Q, 0dB/G 8kHz/F, 1/Q, -5dB/G 1. 25kHz/F, 5/Q, 0dB/G 10kHz/F, 1/Q, -6dB/G 8kHz/F, 5/Q, 0dB/G 1. 6kHz/F, 3/Q, 0dB/G 2kHz/F, 7/Q, +3dB/G 8kHz/F, 5/Q, 0dB/G 80Hz/F, 3/Q, +3dB/G 8kHz/F, 5/Q, 0dB/G 1.

EQ (Parametric Equalizer) functions> Editing the P. EQ menus You can compensate for the frequency characteristics using the basic P. EQ according to your car type. · The P. EQ adjustment contents are as follows: Channel selection Select the channel to be compensated (front or rear). Selection of center frequency Select the center frequency that you want to compensate from the range of 20Hz to 20kHz. (1/3 octave step, 31 points) Selection of Q-curve Set the sharpness of the Q-curve to one of the parameters: 1, 3, 5, 7 and 20. Gain adjustment Adjust the gain (output level) in the range of 12dB to +12dB. (1dB step, 25 points) About the compensation of frequency characteristics See Figure 1 concerning the relationship of the center frequency, Q-curve (Q) and gain. Level (dB) Q curve (Q) F Q= f P. EQ memory (User memory) You can store 6 frequency characteristics into the memory, which are edited on the basis of the basic P. EQ menus. Gain (G) f 3dB Frequency curve Center frequency (F) Frequency (Hz) Figure 1 About the Q-curve (Q) For the Q-curve (Q), setting larger values makes the curve sharper, setting smaller values makes the curve flatter. (Figure 2) Selecting the Q-curve (Q) opposite to the frequency curve to be compensated makes the frequency characteristics flat. Q curve (Q) High Low Q curve; 20 Q curve; 1 Figure 2 DPH910 9 5. Before starting, be sure to disconnect the battery's negative "-" terminal to prevent accidents due to short-circuits.
