Denon AVR-1604, AVR-684 manual 5

2 CAUTIONS ON INSTALLATION

Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV.

If this happens, take the following steps:

•Install this unit as far as possible from the tuner or TV.

•Set the antenna wires from the tuner or TV away from this unit’s power cord and input/output connection cords.

•Noise or disturbance tends to occur particularly when using indoor antennas or 300 Ω /ohms feeder wires. We recommend using outdoor antennas and 75 Ω /ohms coaxial cables.

For heat dispersal, leave at least 0.3 ft (10 cm) of space between the top, back and sides of this unit and the wall or other components.

3CAUTIONS ON HANDLING

•Switching the input function when input jacks are not connected

A clicking noise may be produced if the input function is switched when nothing is connected to the input jacks. If this happens, either turn down the MASTER VOLUME control or connect components to the input jacks.

•Muting of PRE OUT jack, HEADPHONE jack and SPEAKER terminals

The PRE OUT jack, HEADPHONE jack and SPEAKER terminals include a muting circuit. Because of this, the output signals are greatly reduced for several seconds after the power operation switch is turned on or input function, surround mode or any other set-up is changed.

ENGLISH

wall

If the volume is turned up during this time, the output will be very high after the muting circuit stops functioning. Always wait until the muting circuit turns off before adjusting the volume.

•Whenever the power operation switch is in the STANDBY state, the apparatus is still connected on some AC line voltages.

Please be sure to unplug the cord when you leave home for, say, a vacation.

4FEATURES

1.Dolby Digital EX decoder system

Dolby Digital EX is a 6.1-channel surround format proposed by Dolby Laboratories that allows users to enjoy in their homes the “DOLBY DIGITAL SURROUND EX” audio format jointly developed by Dolby Laboratories and Lucas Films and first used for the movie “Star Wars Episode 1 – Phantom Menace”.

The 6.1 channels of sound, including surround back channels, provide improved sound positioning and expression of space.

2.DTS-ES Extended Surround and DTS Neo:6

The AVR-1604/684 is compatible with DTS-ES Extended Surround, a new multi-channel format developed by Digital Theater Systems Inc. The AVR-1604/684 is also compatible with DTS Neo:6, a surround mode allowing 6.1-channel playback of regular stereo sources.

3.Dolby Pro Logic II decoder

Dolby Pro Logic II is a new format for playing multichannel audio signals that offers improvements over conventional Dolby Pro Logic. It can be used to decode not only sources recorded in Dolby Surround but also regular stereo sources into five channels (front left/right, center and surround left/right). In addition, various parameters can be set according to the type of source and the contents, so you can adjust the sound field with greater precision.

4.Dolby Digital decoder

Using advanced digital processing algorithms, Dolby Digital provides up to 5.1 channels of wide-range, high fidelity surround sound. Dolby Digital is the default digital audio delivery system for DVD and North American DTV.

5.DTS (Digital Theater Systems)

DTS provides up to 5.1 channels of wide-range, high fidelity surround sound, from sources such as laser disc, DVD and specially-encoded music discs.

6.Auto Surround Mode

This function stores the surround mode last used for an input signal in the memory and automatically sets that surround mode the next time that signal is input.

7.6CH EXT. IN jacks

This unit is equipped with 6CH EXT. IN jacks for use with audio formats of the future.

8.High performance DSP simulates 7 sound fields

Playback is possible in 7 surround modes: 5/6-channel Stereo, Mono Movie, Rock Arena, Jazz Club, Video Game, Matrix and Virtual. You can enjoy a variety of sound effects for different movie scenes and program sources even with stereo sources not in Dolby Surround.

9.Personal Memory Plus function

Personal Memory Plus is an advanced version of Personal Memory. With Personal Memory Plus, the set automatically memorizes the surround mode, channel volume, surround parameters, etc., for each of the separate input sources.
