Display Features

Detachable Face: The JVC KD-R820BT features a detachable face to deter theft. A hard-plastic face-case is provided. A face-fixing screw is supplied for making the face non-detachable, if desired.

3-Line LCD: The head unit features a three-line, alphanumeric-text LCD with adjustable color, contrast, brightness, and dimmer settings.

Variable Color LCD & Key Illumination: The JVC KD-R820BT 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.

LCD Type: You can select between a Negative or Positive pattern for the display. You can also set the unit to automatically switch to a Positive LCD pattern during the day and a negative LCD pattern during the night.

Brightness/Contrast: The unit offers an adjustable display and button illumination brightness level (0-31) for day and nighttime driving. You can also adjust the display contrast (0-8) to make the display clearer and more legible.

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).

Clock Display: The JVC CD receiver features a 12/24-hour clock display. You can switch between the head unit's source information and clock display when the unit is powered on. When you power the unit off, you can press the "display" button to temporarily view the clock display.

Burr-Brown 24-bit D/A Converter: The JVC KD-R820BT utilizes a premium TI/Burr-Brown 24-bit digital-to-analog converter for superior CD sound quality.

MOSFET Amplifier: The KD-R820BT 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-R820BT 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-R820BT 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)

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.

Amplifier Gain Control: When you are using the KD-R820BT 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/6CH Preamp Output: The KD-R820BT is equipped with three pair of 2.5V preamp outputs (Front/Rear/Subwoofer). The front and rear preamp outputs allow fader control, while the subwoofer preamp output is non-fading.

Subwoofer Level: You can adjust the head unit's subwoofer level between 0 and 8.

Built-in Crossovers: The JVC KD-R820BT 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 variable high-pass filter 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. You can set the cutoff frequency of the high-pass filter at 62Hz, 95Hz, or 135Hz.
• Low-Pass Filter: You can set the cutoff frequency of the subwoofer output's low-pass filter to 55Hz, 85Hz, or 120Hz.

Pro EQ: The KD-R820BT 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.

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