JVC Arsenal KD-AHD79
Our take on the JVC Arsenal KD-AHD79 by Crutchfield's Zak Billmeier
Crystal-clear digital radio
Love listening to local radio? The JVC Arsenal KD-AHD79 CD receiver lets you tap into the wicked digital sound of HD Radio™. When you tune into a participating AM or FM station, you'll really notice the difference in fidelity and reception, plus you can check out the alternate programming offered by many stations. And here's another cool feature — you can adjust this receiver's variable-color display to match your dash lighting. You can even set one color for the main display, and pick another for the buttons and controls.
Tag the tunes you like
First, plug your iPod or iPhone® into the handy front-panel USB slot. Now, get ready to fly through your songs and playlists with the KD-HDR70's controls. You can also switch control to the iPod itself for all those DJs in the back seat. All song and artist info will show up on the receiver's 2-line display.
Once your iPod's connected, you can take advantage of the tagging feature — just "tag" a song you're hearing on an HD Radio station, and you'll be prompted to buy it from the iTunes® store the next time you connect your iPod to the computer.
iPod note: If you're going to use your iPod with this receiver, be sure to check "Details" for specific iPod model compatibility with this receiver or its optional iPod adapter.
It all starts with the sound
You'll get plenty of clean volume without distortion from the muscular built-in amplifier, and you can dial in the perfect tone for your vehicle using the flexible 3-band parametric EQ.
Play all your music
This versatile stereo will handle all your CDs and recordable discs, as well as discs or or thumb drives you've loaded with MP3 and WMA files. With two auxiliary inputs, you can connect a satellite radio dock semi-permanently to the rear input, while you use the front input to plug in a game console or other audio source.
Building a system?
Three sets of high-powered 5-volt preamp outputs send a super-clean signal to your outboard amps. The subwoofer output features a selectable low-pass filter, and you can use the sub level control to add just the right amount of bass. The KD-AHD79 also works with JVC's Bluetooth® adapter so you can conduct phone conversations while both hands stay on the wheel.
Want to keep your steering wheel controls?
In most vehicles, you can use an adapter to connect your vehicle's steering wheel controls to this JVC stereo. Connect a few wires, then program the adapter for your particular car and the JVC, and you'll retain the convenience of your steering wheel controls. Check the "Accessories" tab for compatible adapters.
Really nice head unit with a ton of great features. I like that you can switch the head unit to iPod/iPhone mode, I wish other companies would start doing the same.

Detachable Face: The JVC Arsenal KD-AHD79 features a detachable face to deter theft. A face-fixing screw is supplied for making the face non-detachable, if desired.
Note: No face case is included with this unit. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit.
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-AHD79 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 KD-AHD79 utilizes a 24-bit digital to analog converter for superior CD sound quality.
MOSFET Amplifier: The KD-AHD79 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 KD-AHD79 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 KD-AHD79 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 KD-AHD79 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 KD-AHD79 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).
|Bass||60, 80, 100, 200 Hz||+/- 12 dB (-6 to +6)||1.0, 1.25, 1.5, 2.0|
|Midrange||0.5, 1.0, 1.5, 2.5 kHz||+/- 12 dB (-6 to +6)||0.75, 1.0, 1.25|
|Treble||10.0, 12.5, 15.0, 17.5 khz||+/- 12 dB (-6 to +6)||Fixed|
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.
5V/6CH Preamp Output: The KD-AHD79 is equipped with three pair of 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 Arsenal KD-AHD79 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-AHD79'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.
Built-in HD Radio: With the built-in HD Radio tuner, you can receive digital AM/FM broadcasts from local stations where available. This new technology will significantly improve audio quality and reception, as well as include information such as artist name and song titles or traffic news, viewable on the receiver's display. HD Radio Technology will deliver high-quality digital sound. AM digital will have FM-like quality in stereo, while FM digital will have CD-like quality with static free and clear reception.
Note: Right now there are about 2,000 radio stations broadcasting using digital HD Radio technology in the U.S. To find HD Radio stations in your area, visit the HD Radio website (HDRadio.com).
Multicasting: In addition to conventional broadcasts, with HD Radio broadcasting, it is possible to choose from up to 8 multicast programs (HD1 to HD8 and analog). There are also data programs for each program.
Text Display: AM/FM digital stations can offer text and data such as artist names and song titles. The built-in HD Radio tuner displays song title, artist and station information on the display of the JVC Arsenal KD-AHD79.
Analog Broadcasts: In addition to HD AM/FM stations, the KD-AHD79 can also receive conventional analog AM/FM broadcasts.
Digital/Analog Tuning: You can setup the KD-AHD79 to search both analog and digital radio stations, only HD Radio stations, or analog radio stations only.
Digital/Analog Presets: You can set up to 18 FM and 6 AM digital/analog presets stations as presets (HD Radio multicast channels can also be preset). Presets can be set manually or automatically, using Strong-station Sequential Memory (SSM).
Mono Mode: If an analog FM stereo broadcast is hard to receive, you can manually switch the tuner to Mono operation.
IF Filter: You can also switch the analog tuner's IF filter to Wide or Auto to increase/decrease the sensitivity.
US/European Tuning: You can set the built-in AM/FM tuner between US standard and European tuning spacing.
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 KD-AHD79 can play MP3 (8-320 kbps)/WMA files (8-192 kbps) that have been recorded on CD-R and CD-RW discs.

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 KD-AHD79 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 Port: The JVC Arsenal KD-AHD79 features a front panel USB 2.0 type-A port behind a sliding cover for connection of a USB mass-storage class device.

iTunes Tagging: Using the head unit's iTunes Tagging enabled HD Radio, you can tag your HD music (up to 60 songs) while listening to the radio with your iPod/iPhone connected. When you hear a song you enjoy on your local HD Radio station, you only have to press the head unit's "Tag" button and the song's information will be saved to your connected iPod/iPhone. The saved songs will then show up in a playlist called "Tagged" in iTunes the very next time you sync your iPod/iPhone to your PC. Then you just need to click, buy, and download the song you tagged directly from the Apple iTunes Music Store.
Note: iTunes 7.4 (or later version) is required to purchase tagged songs.
iPod/iPhone Charging: While connected and the ignition switch is set to ACC or ON, the head unit's USB connection will power and charge your iPod/iPhone.
