Display Features

Detachable Face: The JVC Arsenal KDA-625 features a detachable face to deter theft. A face-fixing screw is supplied for making the face non-detachable, if desired.

2-Line LCD: The head unit features a 12-segment, two-line LCD with adjustable color, brightness, and dimmer settings.

Variable Color LCD & Key Illumination: The JVC KD-R620 features 29 color presets for the LCD and button illumination. You can choose one of these color presets or select the ColorFlow mode which scrolls through all 29 color presets. Additionally, there is a User preset, allowing you to individually adjust the intensity of Red, Green, and Blue from 0 to 31; resulting in approximately 30,000 custom color options. The chosen color preset or custom color can be applied to the display panel and the backlighting for all the buttons except the Display, Brightness, & Eject buttons (they remain red). You can choose to use the same color for the LCD display and button illumination, or use a separate color for each one. You can also select a different color for daytime and nighttime in regards to the unit's LCD and button illumination.

Brightness: The unit offers an adjustable display and button illumination brightness level (0-31) for day and nighttime driving.

Display/Button Illumination Dimmer: The display/button illumination dimmer can be set to Off (normal brightness at all times), On (display/button illumination is always dimmed), or Auto (display dims when 12-volts is applied to the orange/white illumination lead).

24 Bit D/A Converter: The JVC Arsenal KDA-625 utilizes a 24-bit digital to analog converter for superior CD sound quality.

MOSFET Amplifier: The KDA-625 is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit.

CEA2006 Compliant: The power specifications for the KDA-625 are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the KDA-625 are as follows:

• CEA2006 Specs: 20 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
• Maximum Power Output: 50 watts x 4 channels (200 total watts)

Amplifier Gain Control: When you are using the KDA-625 with factory speakers (or those rated to less than 50 watts peak), the Amplifier Gain Control can limit the amount of power being sent to those speakers. When the Amp Gain Control is set to "low," the volume control ranges from 0 (minimum) to 30 (maximum). When using speakers rated higher than 50 watts peak, you can set the Amp Gain Control to "high," and the volume control will range from 0 to 50.

Volume Adjust: The input level of each source (other than FM) is adjustable relative to the FM radio volume, so there isn't a significant volume difference when changing sources. Each source is individually adjustable from -5 to +5.

Pro EQ: The KDA-625 is equipped with JVC's Pro EQ. The integrated equalizer offers 7 preset sound modes (Flat, Natural, Dynamic, Vocal Boost, Bass Boost, User) suitable for the music genre of your choice. The User mode allows you to manually adjust the head unit's 3-band parametric EQ (Frequency, Level, and Q-Factor).

Loud (Loudness): This feature boosts low and high frequencies to produce a well-balanced sound at a low volume level. You can turn this feature on or off.

2.5V/6CH Preamp Output: The KD-A625 is equipped with three pair of 2.5V preamp outputs (Front/Rear/Subwoofer). The front & rear preamp outputs offer balance/fade control and are designed to hookup to a full-range 4-channel amplifier. The subwoofer preamp output is non-fading and designed to hookup to a mono-block subwoofer amplifier.

Built-in Crossovers: The JVC KD-A625 features a built-in high-pass filter for the unit's front & rear speakers and a low-pass filter for the unit's subwoofer output.

• High-Pass Filter: You can activate a high-pass filter (fixed) for the unit's front & rear channels (speaker- or preamp-level), so low frequency signals are cut off from your system's front & rear speakers.
• Low-Pass Filter: The unit's subwoofer preamp output features a low-pass filter. In order to prevent high-frequencies from being sent to your system's subwoofers, you can set the cutoff frequency of the low-pass filter to 55Hz, 85Hz, or 120Hz.

Subwoofer Level: You can adjust the KD-A625's subwoofer level (0-8) independently from the head unit's main volume control for added bass volume.

Key-Touch Tone: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

Radio Functions

AM/FM Tuner: The JVC Arsenal KDA-625 features a built-in AM/FM tuner with manual, seek, and preset tuning.

Preset Tuning: You can store a total of 18 FM stations presets and 6 AM station presets. The radio allows you to set your AM/FM stations manually or automatically.

IF Filter: You can also switch the tuner's IF filter to Wide or Auto to increase/decrease the sensitivity.

Mono: If an analog FM stereo broadcast is hard to receive, you can manually switch the tuner to Mono operation.

US/European Tuning: You can set the built-in AM/FM tuner between US standard and European tuning spacing,

Disc Playback

Disc Compatibility: The unit features a single disc player that will playback CD-Audio, CD-Text, and finalized CD-R/CD-RW audio discs.

MP3/WMA Playback: The KDA-625 can play MP3 (8-320 kbps)/WMA files (8-192 kbps) that have been recorded on CD-R and CD-RW discs. The disc must be recorded in one of the following formats: ISO 9660 Level 1/Level 2, Joliet, Romeo or Windows long file. Each disc can have a maximum of 8 folder hierarchies, 255 folders, and no more than a total of 512 files and/or folders on each disc. The unit also supports IDTag3 (version 1.0, 1.1, 2.2, 2.3 or 2.4) for album and artist information from MP3 or WMA files.

Track/Folder List: The Track/Folder List displays a list of MP3/WMA folders and tracks on a loaded CD, so you can easily access your music. The Track/Folder List will also display the list of track titles on a CD Text disc. If the MP3/WMA disc contains a lot of tracks, you can fast search (+/-10 or +/-100) through the disc by turning the unit's control dial quickly.

Random/Repeat Modes: The JVC KDA-625 offers the following Repeat and Random playback modes for your audio CDs.

• Repeat: Track Repeat (plays the current track repeatedly), Folder Repeat (plays all tracks of the current folder repeatedly), Off (cancels repeat function)
• Random: Folder Random (plays all tracks of the current folder, then the tracks of the next folder in random), All Random (plays all tracks of the current disc at random), Off (cancels random function)

Disc Resume: If you change the source, playback also stops (without ejecting the disc). Next time you select CD for the playback source, the disc will start from where it has been stopped previously.

Off Insert/Eject: A CD disc can be inserted or ejected with the power off. When a disc is inserted with the power off, the unit will automatically power up and begin playback.

Disc Protection: If the ejected disc is not removed within 15 seconds, the disc is automatically inserted again into the loading slot to protect it from dust. The source will change to CD, and the disc will begin playback, even if you have another source selected at the time.

Mounting: For proper disc playback you must install the unit within 30-degrees of horizontal.

USB/iPod/Aux Connectivity

USB Port: The JVC Arsenal KDA-625 features a front panel USB 2.0 type-A port behind a sliding cover for connection of a USB mass-storage class device.
