MOS-FET Amplifier: The JVC CD player features a CEA-2006 compliant MOS-FET 20 Watts RMX x 4-channel amplifier in 4ohms at 1% THD+N with an 80 dBA signal-to-noise-ratio.

DiAS II Tuner: This model is equipped with JVC's Digital Intelligent Advanced Sensing tuner, offering unprecedented analog radio performance with higher sensitivity and selectivity. You can set up to 18 FM and 6 AM stations as presets. Presets can be set manually, or automatically using Strong-station Sequential Memory (SSM). If an FM stereo broadcast is hard to receive, you can manually switch the tuner to "Mono" operation. You can also switch the tuner's IF filter to Wide or Auto to increase/decrease the sensitivity.

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. In addition, AM/FM digital stations can offer text and data such as artist names and song titles. Many HD Radio stations also offer more than one channel of programming. This service is called multicasting. You can setup the KD-HDR50 to search only HD Radio stations. To find HD Radio stations in your area, visit HDRadio.com

HD Radio/iTunes Tagging: This iTunes Tagging feature lets you Tag songs you hear on HD Radio stations and stores the info on your connected iPod through the unit's USB port. The next time you connect your iPod to iTunes, you will be able to preview your selections and then purchase and download them from directly from iTunes.

MP3/WMA Playback: The KD-HDR50 can play MP3/WMA (32-320 kbps) files 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, or Romeo. Each disc can have a maximum of 8 folder hierarchies, 255 folders, and no more than a total of 512 files 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.

Intelligent EQ (7-Band iEQ): This model has Rock, Classic, Pops, Hip Hop, Jazz, Flat, and User preset EQ curves. The User preset can be adjusted to your preference and stored in memory. For the User preset, you can independently adjust the following frequencies: 60 Hz, 150 Hz, 400 Hz, 1 kHz, 2.4 kHz, 6 kHz, and 15 kHz. The level of each frequency can be adjusted from -10 to +10 in increments of two.

Amplifier Gain Control: When you are using the KD-HDR50 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.

Subwoofer Output: In addition to the 2.5-volt gold-plated front preamp output, this unit has a set of 2.5-volt gold-plated subwoofer preamp outputs. The subwoofer output has independent level control, adjustable from 00 to 08, and a selectable low-pass crossover. You can select a cutoff frequency of 72, 111, or 157Hz.

Front Panel Auxiliary Input: A front panel stereo minijack is provided to allow the connection of a portable audio source. Just connect your portable cassette, MD or MP3 player to this unit, and you can listen to the audio from the portable player through the speakers in your mobile audio system.

Optional Input Adapter: An optional JVC Line Input Adapter (item number 105KSU57 or 257KSU58) may be used to provide an additional auxiliary audio only input on this unit. This feature allows you to connect a portable audio player, such as a portable MP3 player, to this unit as an additional audio source. The adapter connects to the CD changer input on this unit. When the adapter is connected to this unit, a CD changer cannot be connected.

Source Level: You can adjust the volume (-10 to +10) of each source (except FM) compared to the unit's FM volume level. The volume level will automatically increase or decrease when you change sources.

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; playback starts automatically.

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.

Variable Illumination: You can change the head unit's display and button illumination between 29 preset shades of white, blue, purple, red, orange, yellow, aqua, and green. Additionally there is a custom User setting, allowing you to individually adjust the intensity of the red, green, and blue between 0 and 31, resulting in 32,767 possible color options.

Dimmer: When 12 volts is applied to the illumination lead and the dimmer set to Auto, the display dims. The dimmer can also be set to Off (normal brightness at all times) or On (display is always dimmed).

Clock Display: While playing a CD, you can switch between the clock display and the CD elapsed time display (the track number always appears). While listening to the radio you can switch between the clock display and the station frequency display. When you press the Display button during power off, the unit will turn on, display the clock for 5 seconds, then shut off. This can be done with the ignition on or off. In the menu, the clock can be set to display with the unit on or off, only turning off when the ignition is turned off ("keyed" operation).

Wireless Remote Control: The KD-HDR50 comes supplied with a wireless remote control (RM-RK50). The remote contains Power, Attenuator, Sound, Source, Tracking and Volume functions.
