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 jacks and SPEAKER terminals

The PRE OUT jacks and SPEAKER terminals include a muting circuit. Because of this, the output signals are greatly reduced for several seconds after the power switch is turned on or input function, surround mode or any other-set-up is changed. 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 switch is in the STANDBY state, the apparatus is still connected on AC line voltage.

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

4FEATURES

1.Digital Surround Sound Decoding

Featuring dual 32 bit high speed DSP processors, operating entirely in digital domain, surround sound from digital sources such as DVD, DTV and satellite are faithfully re-created.

2.Dolby Digital

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 North American DVD and DTV, and is available on laser discs as well as some digital satellite direct-to-home services.

3.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.

4.Lucasfilm Home THX Ultra Certified

Home THX is the unique collaboration between Lucasfilm Ltd. and audio equipment manufacturers. THX Ultra certification is the highest performance level, and provides a rigorous set of performance standards, along with proprietary surround sound post-processing technologies, designed to enhance the surround soundtrack playback experience in the home theater.

5.THX Surround EX

By adding a 2-channel power amplifier and two surround back speakers, the system becomes fully compatible with THX Surround EX, the latest surround format.

6.Wide screen mode for a 7.1-channel sound even with 5.1-channel sources

DENON has developed a wide screen mode with a new design which recreates the effects of the multi surround speakers in movie theaters. The result is 7.1-channel sound taking full advantage of surround back speakers, even with Dolby Pro Logic or Dolby Digital/DTS 5.1-channel signals.

7.24 bit D/A Conversion

All eight channels, including the seven main channels and the low frequency effects (LFE) channel benefit from reference ANALOG DEVICES DACs, for optimum high fidelity reproduction of music and movie soundtracks.

8.Dual Surround Speaker Mode

Provides for the first time the ability to optimize surround sound

reproduction using two different types of surround sound speakers as well as two different surround speaker positions:

(1) Movie Surround

Motion picture soundtracks use the surround channel(s) to provide the ambient elements of the acoustic environment they want the audience to realize. This is best accomplished by the use of specially-designed surround speakers that offer a wide diffusion pattern (bipolar dispersion) or by using surround speakers that provide broad dispersion with a minimum of on-

axis localization (dipolar dispersion). Side wall mounting (closer to the ceiling) of the surround speakers provides the greatest envelopment, minimizing localization of direct sound from the speakers.

(2)Music Surround

With full range discrete surround channels, as well as three discrete full range front channels, digital formats such as Dolby and DTS offer thrilling surround sound music listening. Producers of multi-channel discrete digital music recordings almost always favor the use of direct radiating (monopolar) surround speakers, placed in the rear corners of the room, since that is how they configure their studios during the mixing/creation process.

The DENON AVR-4800 provides the ability to connect two different sets of surround speakers, and place them in the appropriate locations in your home theater room, so that you can enjoy both movie soundtracks and music listening, with optimum results and no compromise.

9.Component Video Switching

In addition to composite video and “S” video switching, the AVR- 4800 provides 2 sets of component video (Y, R-Y, B-Y) inputs for the DVD and TV/DBS inputs, and one set of component video outputs to the television, for superior picture quality.

10.Video Select Function

Allow you to watch one source (visual) while listening to another source (audio).

11.Five Identical Power Amplifiers

Featuring discrete high current power transistors, the power amp section is THX Ultra certified for top performance with the widest range of speaker systems. Rated at 125 watts into 8 Ω /ohms, the amp channels feature additional low impedance drive capability.

12.Future Sound Format Upgrade Capability via Eight Channel Inputs & Outputs

For future multi-channel audio format(s), the AVR-4800 is provided with 7.1 channel (seven main channels, plus one low frequency effects channel) inputs, along with a full set of 7.1 channel pre- amp outputs, controlled by the 8 channel master volume control. This assures future upgrade possibilities for any future multi- channel sound format.

13.Amplifier assign function for greater liberty in upgrading the system with an external power amplifier

When using an external power amplifier (option) to upgrade to a THX Surround EX system, you can choose whether to use the internal amplifier for the front channels or the surround back channel. Even when the system is upgraded with an external power amplifier for the front channels the internal amplifier can be used for the surround back channel.
