Discrete Construction Chassis and Direct Signal Routing
The interior of the chassis is divided to give separate compartments for the power amplifier, pre-
amplifier, 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-
Channel Stereo, Classic Concert, Rock Arena, Jazz Club, Super Stadium, Mono and Matrix.
Cinema Equalizer
This circuit makes the overly bright sounding dialog heard on some movie soundtracks easier to lis-
ten to.
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.
DDSC-Digital (Dynamic Discrete Surround Circuit-Digital)
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.
Fully Discrete 5-channel Equal Power Amplifier
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.
