K2 Technology for Enhanced Digital Sound Quality
K2 is a JVC/KENWOOD’s original technology that reproduces the original master sound by expanding the bit rate and frequency range. K2 is compatible with all sources including CD. For example, K2 will expand the digital data of the audio CD recorded at 44.1kHz/16 bit to 48 kHz/24 bit, and recreate the high-frequency range above 20kHz that is cut during the CD formatting.

Time Alignment
By selecting the speaker type and the distance to the centre of the listening position, the head unit will automatically adjust the timing of the sound output from each of the speakers so that the sound from each of the speakers will arrive exactly at the same time to the listening position.

Space Enhancement
Space Enhancement is a virtual surround technology using 2 speakers. Just select the vehicle size, and the head unit automatically adjusts the sound effectively.

Sound Response
This function boosts the low frequencies which can be lost during compression to MP3 or AAC.

Sound Lift
Virtually manipulate the height of the speakers by adjusting the sound frequencies.

Volume Link EQ
Volume Link EQ boosts specific frequencies in the audio signal to compensate for the impact of road noise. It boosts frequencies in the music that are affected by road noise.

13-Band Equalizer
Use the 13-Band Equalizer to manually adjust the sound to your taste.

Internet Radio/Digital Radio
Listen to Pandora, iHeartRadio, and Spotify from your Smartphone with smooth control on the head unit via USB or Bluetooth connection for iPhone, and via Bluetooth for Android devices. Ready for SiriusXM Radio. You can listen to over 100 Channels of music, sports, and entertainment.

24bit FLAC Compatible with Tag
Compatible with FLAC format which allows digital audio to be losslessly compressed, so that file size is reduced without any information being sacrificed. Also compatible with playback of 24bit / 96kHz FLAC format.

Remote Control App
Control the receiver's source directly from the Smartphone using simple finger gestures with "JVC Remote" app* now available for both iOS and Android. You can even customize your audio setting, and see detailed source information such as song title, artist name and album art etc. from the Smartphone.

Owner's Manual​

About Rockville Quality Control Procedures:
The Rockville brand stands for Quality, Innovation and Value. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville products are backed with a hassle free warranty, though it is unl ikely that you will need to use it.
