Our take on the JVC KD-R640
You like to go your own way. You zig when others zag. So clearly the standard red or blue illumination display for your car stereo won't do. JVC's KD-R640 CD receiver offers the choice of over 30,000 different colors for the display and controls on this receiver. You can assign different colors to the display and controls, and even set the receiver to cycle through all colors for constant variety.
Easy access to your choice of music
Use the easily accessible front-panel USB port for your iPod, iPhone, or Android phone, then use this JVC's driver-friendly controls to access and enjoy your playlists. Or load a thumb drive up with your favorite tunes and rock out that way. And if you're a CD fan, you've got the option to drop in a disc, too. The KD-R640 includes a front auxiliary input for a Dock-and-Play satellite radio or other sound source.
Awesome sound, no matter what source
You can make fine adjustments to the highs, mids, and lows with the 3-band parametric EQ, and you can use the built-in high-pass filter to trim the low bass from your speakers, allowing them to run at peak efficiency. You'll find two sets of preamp outputs for connecting amps and subs, and you can even switch the rear preamp outputs to subwoofer mode, then use the subwoofer level control for on-the-fly changes.
You can zero in on an exact match for your car's dash lighting, or just go wild.
Add hands-free calling
It's never wise to handle your phone while driving. Experience the safety and convenience of hands-free calling by adding JVC's Bluetooth® adapter. When a call comes in, you'll talk naturally and hear your caller over your speakers – just like you're talking to someone in the front seat. You can keep both hands free and concentrate on your driving. The adapter also gives you the ability to stream music from a compatible device straight into the JVC.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.

24 Bit D/A Converter: The JVC KD-R640 utilizes a 24-bit digital to analog converter for superior sound quality.
MOSFET Amplifier: The KD-R640 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-R640 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-R640 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-R640 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.
2.5V/4CH Preamp Output: The KD-R640 is equipped with two pair of 2.5V preamp outputs (Front, Rear/SW). You can set the Rear/SW preamp outputs for connecting a pair of full-range rear speakers (through an external amplifier) or for connecting a subwoofer (through an external amplifier). When set for rear speakers, the rear outputs operate with the unit's fader control. When set for subwoofer, the outputs are non-fading.
Subwoofer Controls: When the unit's Rear/SW preamp output is set to Subwoofer, you can set the cutoff frequency of the low-pass filter at 55Hz, 85Hz, or 120Hz. You can adjust the head unit's subwoofer level between -8 and +8 (separate from the main volume level).
Pro EQ: The KD-R640 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|
Note: You can store Pro EQ bass, middle and treble tone settings for each source (CD, AM/FM, Aux, USB, iPod, Bluetooth, and Pandora).
Bass Boost: The unit's Bass Boost enhances low bass frequencies.
Loud (Loudness): This feature boosts low and high frequencies to produce a well-balanced sound at a low volume level. You can set this feature to High, Low, or Off.
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.
Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.
Detachable Face: The JVC KD-R640 features a detachable face to deter theft. No face-case is provided. An optional soft face case (142DFC1X, sold separately) can be purchased for this unit. A face-fixing screw is supplied for making the face non-detachable, if desired.
Variable Color LCD & Key Illumination: The JVC KD-R640 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 eject button (it remains 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).
Wireless Remote Control: The KD-R640 comes supplied with a wireless remote control (RM-RK52). The remote contains Attenuator, Sound, Source, Tracking, and Volume functions. The remote operates off of a single CR2025 3V Lithium-cell battery (included).
Optional Bluetooth: The JVC KS-BTA100 Bluetooth Adapter (105KSTBA10, sold separately) provides Bluetooth hands-free communication and digital audio streaming functions for the JVC KD-R640. The JVC KS-BTA100 gives you hands-free communication from your compatible Bluetooth mobile phone and wireless streaming audio from a Bluetooth enabled digital audio player, when connected to the JVC in-dash head unit. The JVC Bluetooth Adapter includes a super-sensitive microphone, an Answer/End button, and playback controls. The JVC KD-R640 can be set to automatically mute any music audio to your vehicle's speakers so you can listen to your telephone call using your car speakers.
Note: Not all Bluetooth devices will be compatible. Visit the JVC Mobile Entertainment Bluetooth Support Page for a complete list of compatible Bluetooth enabled devices.
