The First Name In Digital Audio

AVR-3600

DDSC-Digital (Dynamic Discrete Surround Circuit-Digital)

Since surround signals are all processed in the digital domain, the AVR-3600 is equipped with a newly-developed, sophisticated, high-performance DSP circuit with "Full Block Floating point" calculations for the Dolby Digital AC-3, Dolby Pro Logic decoder and Surround Simulator. The D/A converters feature high-resolution, multi-bit designs for

all the Front L/R, Center, Surround L/R, and Subwoofer channels. This combination of DSP and D/A converters

works to bring out the tremendous potential of AC-3 sound. In addition, high resolution A/D converters have been

incorporated for the Dolby Pro Logic decoder. The merits of all the latest technologies have been harnessed to

reproduce the absolute highest quality in sound possible today.

Fully Discrete 5-channel Equal Power Amplifier

AVR-3600 offers a full discrete 5-channel power amplifier to support the dynamic performance of the Dolby Digital AC-3 sound signal from Laser Disc or DVD. All channels have an equal power output of 110 watts each (8 ohms, 20Hz - 20kHz, THD 0.05%) and are configured as independent monaural amplifiers.

This construction enables the AVR-3600 to produce dynamic realism through its high-current capability

and to recreate a nuanced surround sound effect via superior channel separation.

Powerful, Responsive Power Supply

AVR-3600 incorporates three independent power transformers for each power amplifier, preampli-

fier and micro-processor to ensure a stable current supply for each block without mutual interfer-

ence and noise. Furthermore, the transformer of the preamplifier employs separate windings for

the audio amplifier, digital circuitry and video circuitry to prevent interference.

Discrete Construction Chassis and Direct Signal Routing

The interior of the chassis is divided to give separate compartments for the power amplifier, preamplifier, video circuit, digital circuit and power supply. This design prevents mutual interference

and allows each section to perform at its full potential.

Dynamic Compression Circuit

This parameter is used when the listener wants to reduce the relative loudness between the soft

and loud portions of the sound (dynamic range). The control of the volume range allows for better

low-level listening of dynamic sound tracks like action movies.

Dialog Normalization (On/Off)

This circuit recognizes a “cue” in the Dolby Digital signal that “knows” the average dialog level of

that program and adjusts the level of your system so that large changes in volume between pro-

grams are avoided. This feature allows all Dolby Digital sound tracks to be reproduced at the same

subjective loudness without affecting their dynamic range and prevents “overpowering” the

important dialog audio track.

Rich Selection of Surround Modes

The AVR-3600 offers as many as nine surround sound modes, which is more than enough to sat-

isfy the needs of most home theaters. You can choose from among Dolby AC-3, the three Dolby

Pro Logic modes of Normal, Wide, and Phantom, or from seven additional surround modes: 5-

This circuit makes the overly bright sounding dialog heard on some movie soundtracks easier to lis-

Channel Stereo, Classic Concert, Rock Arena, Jazz Club, Super Stadium, Mono and Matrix.
