Rock the house! This high-powered system features JVC's innovative GigaTube design — top-mounted ducts which connect to two large acoustic chambers. It's all part of the Advanced Labyrinth Aero Port System, and what it gives you is incredibly big bass!

JVC's triple-tray design gives each CD its own tray, so you can get to the disc you want right away. Don't forget the optical digital output — great for recording your favorite tunes to an external CD or MD recorder. Enjoy CD-to-tape or tape-to-tape dubbing with the dual auto-reverse cassette deck, or easy access to your favorite radio stations using the AM/FM tuner presets. And with 370 watts total power driving biamped, 3-way speakers (including twin 6-5/16" subwoofers), you'll hear it all in clear, rich detail.

Inputs and Outputs


Sound Modes: This system has 3 surround modes and 3 Sound Effect Amplifier modes, allowing you to adjust the quality of sound depending on the source you are using. You can select from the following surround modes: D.Club (increases resonance and bass), Hall (adds depth and brilliance to the sound), or Stadium (adds clarity and spreads the sound). You can select from the following Sound Effect Amplifier modes: Rock (boosts the low and high frequencies; good for acoustic music), Pop (good for vocal music), or Classic (good for classical music). In addition to the 6 preset modes, the Manual mode allows you to adjust and store up to three custom EQ curves into memory.

Subwoofer Level Control: Separate from the main system volume control, you can adjust the subwoofer level to one of four settings.

Daily Timer: You can use the daily timer as an alarm clock to wake up to a cassette, a CD, the radio, or a connected auxiliary component. Once the timer is active, it will operate everyday at the set time. Note: If the daily timer is set to come on while the recording timer is operating, the daily timer will not come on at all.

Recording Timer: Once daily, you can record from a preset radio station to the cassette deck. The timer allows you to specify a start and stop time. Note: The recording timer has priority over the daily timer and sleep timer.

Sleep Timer: The sleep timer switches the system off after a specified amount of time so you can fall asleep without worrying about the stereo being left on all night. The sleep timer can be set to 10, 20, 30, 60, 90, or 120 minutes. Note: If the recording timer is set to come on while the sleep timer is operating, the sleep timer will not operate.

Tuner Features

Overview: This system has a digital AM/FM Tuner. You can store up to 45 station presets so that you always have easy access to your favorite stations without having to tune them in manually each time. The tuner has three tuning modes: Manual, Preset, and Auto (seek) tuning. If you are listening to an FM station in stereo and the reception is weak, you can improve the sound quality by switching to Mono. Note: FM tuning is done in 0.1MHz steps and AM tuning is done in 10 kHz steps.

CD Features

CD Player: This system has 3 separate motorized CD trays.

Disc Exchange: You can exchange two discs while playing a third.

CD Compatibility: This unit will play prerecorded CDs, finalized CD-R discs and finalized CD-RW discs.

Program Play: Up to 32 tracks can be programmed and played in any order.

Random Play: When Random Play is selected, the tracks on all loaded CDs are played in random order.

Repeat Play: You can select Repeat All, Repeat 1 Disc, or Repeat 1. When Repeat All is selected, the changer repeats all the tracks on all the loaded discs. When Repeat 1 Disc is selected, the changer repeats all the tracks on the current disc. When Repeat 1 is selected, the changer repeats the current track. In addition, you can repeat Program Play and Random Play.

Tray Lock: This feature allows you to lock the CD trays and prohibit discs from being ejected.

Cassette Features

Dual Auto-Reverse Cassette Decks: In addition to the tuner and three CD trays, this system has dual auto-reverse cassette decks.

Recording: Using a Type I tape in Deck B, you can record from a CD, a cassette, the radio, or a connected auxiliary component. Deck A does not have recording capabilities.

Auto Tape EQ: The cassette decks automatically determine the proper bias setting and allow you to play Type I, II and IV tapes.

Automatic Music Search (AMS): This feature rewinds the tape to the beginning of the current track or fast forwards the tape to the beginning of the next track. It does this by detecting the blank spaces between the songs.

Relay Play: This feature automatically begins playing the second tape when the first tape is finished.

CD Direct Recording: This feature allows you to record a CD to tape by just pushing the CD Rec Start button.

Auto Edit Recording: By using Auto Edit Recording, you can record the CD tracks to fit the tape. Auto Edit Recording makes a program by selecting the CD tracks in numerical order. However, to prevent the end of the last track on the front side from being cut off, the last track is selected so as to fit on the remaining tape length. You can select the following tape lengths: 40, 46, 50, 54, 60, 64, 70, 74, 80, 84 or 90 minutes.


Speaker Design: The system comes with 3-way, ported speakers that employ JVC's Bandpass Subwoofer Speaker System technology and GigaTube design. Each speaker uses a 2" paper cone tweeter, a 3-15/16" poly cone midrange with a rubber surround, and a 6-5/16" paper cone woofer with a foam surround. Each cabinet has a top-mounted GigaTube port that connects to a large acoustic chamber, giving you incredible bass. Each speaker is bi-amped (with 130 watts for the subwoofer, plus 55 watts for the midrange and tweeter) so your music stays clear when it gets loud.
