Inputs and Outputs Notes
Digital Signal Processor: The AVR-1603
features a 32-bit "Melody 32" DSP processor from Analog
Devices. This high-quality DSP chip gives the receiver the ability to accurately
decode Dolby Digital, DTS and Dolby Pro Logic II.
24-bit, 96 kHz D/A
Converters: The AVR-1603 uses highly
accurate 24-bit, 96 kHz D/A converters on all channels to handle digital-to-analog conversion, giving you superior sound quality.
receiver incorporates a wide variety of surround modes to bring you maximum
enjoyment from your audio and video software. The surround modes include:
- Dolby Digital
- Dolby Pro Logic II (Movie and
- Rock Arena
- Jazz Club
- Video Game
- Mono Movie
Multi-Channel Input: The AVR-1603 is equipped with a 5.1-channel input to accommodate outboard decoders. It has a
wide bandwidth of up to 100kHz to accommodate high-resolution audio sources such as
DVD-Audio and SACD.
Personal Memory Plus:
The Personal Memory Plus function automatically memorizes the surround mode,
channel volume, surround parameters, and other settings for each of the separate
The Cinema EQ function gently decreases the level of the extreme high
frequencies, compensating for overly-bright sounding motion picture soundtracks.
Select this function if the sound from the front speakers is too bright. This
function only works in the Dolby Pro Logic, Dolby Digital, and DTS surround
Dynamic Range Compression:
Motion picture soundtracks have tremendous dynamic range (the contrast between
very soft and very loud sounds). For listening late at night, or whenever the
maximum sound level is lower than usual, the Dynamic Range Compression allows
you to hear all of the sounds in the soundtrack (but with reduced dynamic
range). This only works when playing program sources recorded in Dolby Digital. You can select one of the four settings: "Off", "Low",
"Mid" (middle), or "Hi" (high).
Subwoofer Crossover: The
cutoff frequency of the subwoofer preamp output is selectable between 80, 100,
Component Video Switching: This
receiver has two sets of component video inputs and one component video
"monitor" output with a bandwidth of 27MHz.
Last Function Memory:
This unit is equipped with a last function memory, which stores the input and
output setting conditions as they were immediately before the power was switched
The unit is also equipped with a back-up memory. This function provides
approximately one week of memory storage when the main unit's power switch is
off and with the power cord disconnected.
Multibrand Remote (RC-920):
In addition to controlling the AVR-1603 and other Denon A/V components, the supplied remote is pre-programmed
to control many brands of A/V components, including DVD players, Video Disc
players, VCRs, CDs, CD Recorders, Tape decks, Minidisc Recorders, Cable Boxes,
DBS (Satellite) receivers, and TVs.
and Outputs Notes
Speaker Outputs: The
AVR-1603 offers Front "A" and "B" speaker outputs, allowing
you to connect a second pair of speakers for another room. Because the
"A" and "B" speaker outputs are wired in parallel, the
minimum impedance is 6 ohms when using "A" or "B" and 12
ohms when using "A" and "B" speakers together.
receiver is equipped with binding post connectors for the front left, front
right, center, surround left and surround right speakers. They are
not 5-way binding posts because a plastic collar prevents their use with spade
lugs and they are positioned too far apart to be used with dual banana plugs.
The left and right "B" speaker outputs are spring clips which can
accept bare wire and pin connectors.
Panel Inputs: The
receiver has a set of A/V inputs on the front panel behind a removable cover. It
includes stereo audio RCA jacks, a composite video jack, and an optical
