ABOUT THE AV1
Thank you for purchasing the AV1 Digital Controller, an 8-channel
audio and video control center. The AV1 includes eight config-
urable inputs, each of which can be assigned to its eight digital
audio, eight analog audio, five composite video, five S-video or
three component video input connectors. The analog connectors
can be configured for up to two 5.1-channel sources.
Inside and out, the AV1 is designed for possible future develop-
ments. The rear panel houses two RS-232 connectors; one capable
of performing configuration downloads and Flash memory soft-
ware upgrades and the other capable of supporting future software
developments.
More than just an audio and video control center, the AV1 offers
the latest version of the critically acclaimed LOGIc7 decoding,
which creates a 7.1-channel output signal from stereo, 5.1- and
6.1-channel sources. Unlike other decoders, LOGIC7 decoding is
compatible with all input sources and requires no special encoding.
Because the improvement it provides is clearly audible, LOGIC7 is
widely regarded as the finest decoder available.
In addition to LOGIC7, the AV1 offers Dolby Digital Surround EX,
Dolby Pro Logic™II, Dolby Pro Logic, DTS
® 96/24, DTSNeo:6 ® ,
DTS-ES ® , THX Ultra2™ and THX ® Surround EX decoding. THX
Ultra2 certification guarantees that the AV1 meets the highest
THX specifications.
With four floating-point SHARC™ digital signal-processing (DSP)
engines, the AV1 boasts enormous processing power. These power-
ful processors perform custom processing such as LOGIC7 decod-
ing, bass enhancement, dialog enhancement, auto azimuth, 5-
speaker enhancement, bass management, high-precision digital
crossovers and audio controls. These features are available at sam-
ple rates up to 96kHz, with 24-bit resolution to retain top perfor-
mance from all sources. In addition, a fifth DSP engine is dedicated
to decoding multi-channel compressed audio sources.
The AV1 is one of the most advanced audio and video control
centers available. High-precision 24-bit/96kHz A/D converters can
be used to convert stereo analog audio input signals to digital sig-
nals, allowing the AV1 to provide the benefits of precise digital
signal processing without sacrificing signal integrity. Alternatively,
stereo analog signals can bypass A/D conversion and internal pro-
cessing, following a pure signal path directly to the output con-
nectors.
Digital audio input signals are processed through a two-stage
phase lock loop for extremely low intrinsic jitter and high jitter
rejection. Auto azimuth technology corrects timing and level imbal-
ances in stereo sources, ensuring exceptionally accurate playback of
surround-encoded sources.
