• Audiophile sound quality and construction: all analog

gain blocks are fully discrete; premium components and
hand-matched transistors used throughout; two sepa-
rate independent linear power supplies with toroidal
transformers isolate analog and digital circuitry pre-
venting crosstalk or interference.

• Easy to use — automatically detects input signal bit-

stream type and adjusts mode. LCD window shows
decoding and signal information and error messages;
LED

indicators show button selections. Clean uncluttered

control layout.

• Flexible input management: select from 11 sources,

including 6 digital and 1 with discrete analog 5.1 input.
Toggle button switches easily between digital and ana-
log inputs.

• 6 Balanced (XLR) outputs.
• 6.1 and 7.1 channel RCA outputs for Surround EX™ and

DTS - ES modes.

• Stereo and Mono down-mixing options for all surround

modes.

• Digital bass-management modes for all speaker setups.
• Bass redirection modes for any speaker set-up.
• Dynamic-limiting for late-night enjoyment of Dolby

Digital, DTS.

• Music  DSP modes: Natural, Club, Stadium, Hall,

Theatre, Church.

• Party mode (5-channel summed mono distribution for

even room-coverage) and 5-channel Stereo option
(stereo fed to front & rear).

• Easy set-up — LCD window provides built-in menus for

speaker setup, and trim and delay adjustments, and dis-
plays error messages. Built-in test-signal generator and
test sequencer makes calibration simple.

• Individually adjustable trims and delays for each chan-

nel. Level trims may also be fine tuned using the remote.

• Each input can have preferred mode saved.
• Integrates with external control systems (AMX, Crestron,

and others).

• Control port for external video switchers including the

Bryston SPV-1.

• Two 12-volt trigger outputs.
