Cut and pasted from their flyer. The SP-1.7 is supposed to start shipping this month. Since this hasn't even been posted on their site yet, I would expect the specs are still subject to change. Most of the specs are carried over from the SP-1 though. I've highlighted the changes that I could identify. Enjoy. Update: Information on the SP-1 to SP-1.7 upgrade has been posted on their site. Update: The SP-1.7 is THX Ultra2 certified. It appears the flier was incorrect. Update: Looks like I got fed incorrect information. The SP-1.7 is only THX Ultra and will not be Ultra2 certified. Sorry about the mix-up. • Processes Dolby, DTS, THX, and PCM formats: Dolby Digital, Dolby Pro Logic and Pro Logic II, DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, DTS Neo:6, THX Surround EX, THX Ultra certified, PCM 32kHz, 44kHz, 48kHz, 96kHz sample rates. • Easy to use — automatically detects input signal bitstream type and adjusts mode; LCD display shows decoding and signal information. • 6.1 channel and 7.1 channel outputs for EX and ES modes. • 5.1 analog direct input. • Easy to set-up — LCD window provides built-in menus for speaker setup, and trim and delay adjustments, and displays alert messages. • Hand-held, back-lit, 30-button, infrared remote control included. • Balanced (XLR) outputs for 5.1 channels. • Allows selection from up to 11 source components. • Input formats: 4 inputs which may be toggled to either digital or stereo analog sources, 1 discrete analog 5.1 input set, 2 dedicated analog stereo inputs. • Digital Inputs: 4 coaxial inputs, 2 TOSLINK assignable on Consumer Model, or 1 assignable to AES/EBU on Pro Model. • 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). • DSP circuitry can be bypassed and unit operates in pure analog as stereo audiophile pre-amp. • Dynamic-limiting for late-night enjoyment of Dolby Digital, DTS. • Mono and stereo down-mixing option for all modes. • Digital bass-management modes for all speaker setups. • Digital toggle button switches easily between digital and analog. • Stereo and Mono downmixing options for all surround modes. • Bass redirection modes for any speaker setup. • “Smart” subwoofer output provides summed signal in stereo bypass mode. • All analog gain blocks are fully discrete. • Two separate independent linear power supplies isolate analog and digital circuitry preventing crosstalk or interference. • Crystal Semiconductor 24-bit, 192kHz D/A Converter. • Motorola DSP engine. • Standby Power Mode allows remote power up. • Built in test-signal generator and test sequencer for easy set-up. • Each input can have preferred mode saved. • Individually adjustable trims and delays for each channel. • Saves all settings on Power Down. • 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 allow for remote on/off of your amplifier(s) and other home theater accessories such as motorized screens and drapes. • Easy software upgrade via ROM change. • Pin-to-pin compatible digital board allows easy hardware upgrades for future formats or digital processing technologies. • DACs can run up to 192kHz sample rates for future upgrades • Hand selected and matched transistors. • Premium components, such as 1% metal-film resistors, polystyrene capacitors, glass-epoxy circuit boards, toroidal power transformers, and gold-plated RCA/XLR connectors. • Hand assembly. • Extensive 100-hour test and “burn-in” procedure on every unit. • Rugged reliable construction. • 20-Year unlimited transferrable warranty.
