Disk Drive
CPU	Analog Devices BlackFintm ADSP-BF537 DSP
RAM	32 megabytes SDRAM (16 meg x 16 bits)
ROM	1 megabyte FLASH EEPROM (512 K x 16)
Disk Drive	3.5" IDE drive, 80 gigabytes capacity standard, over 270 gigabytes capacity optional
LAN connection	One 10/100 base-T Ethernet port, RJ-45 connector
Serial channels	One RS-232 Asynchronous serial port female DB-9 connector
User Controls
Rear panel switches	Single momentary push-button, system reset
Front panel display	One 128 by 64 pixel monochrome graphic LCD display
Front panel switches	4 Momentary push-buttons
Audio Resources
Analog audio outputs	4 balanced outputs via Neutrik NC3MBH XLR connectors
Output level	12 VRMS into 600 ohms each output (maximum)
Dynamic range	120 db (DAC specification)
THD+N	-107 db (DAC specification)
Volume control	0 to –127.5 db, in 0.5db steps, independent, each channel
Analog audio inputs	-none-
Digital audio outputs	2 AES/EBU serial digital outputs using one (but not both) of either a 110 ohm balanced and isolated output via an XLR type connector, or an unbalanced 75 ohm output via a BNC connector. 2 optical TORX style outputs are also provided and available simultaneously.
Optional Digital audio inputs	1 AES/EBU serial digital input using one (and only one) of either a 110 ohm balanced and isolated input via an XLR type connector, or an unbalanced 75 ohm input via a BNC connector, and 3 optical TORX style inputs. Only one of the four available inputs may be selected for use at any time.
Digital audio matrixing	The AES/EBU and optical inputs are hardwired to a AKM 4122 SRC (Sample Rate Converter). This device provides 4 internal interconnection modes between the AES/EBU/ Optical I/O pins and its serial digital audio I/O pins. Further, the SRC serial digital audio I/O (clocks and data), 5 PLL derived internal clocks, and the 2 DAC serial digital audio inputs are all routed to a CPLD that can be re-configured "on the fly" providing a cross-point switch function for all serial digital audio signal sources and sinks.
Digital Control Circuits
"Contact closures"	Two sets of 6 form 1A contact pair outputs (single pole, single throw, normally open) and 4 Optically isolated inputs are provided. These input/output contact pairs are made available via two 25 pin female D-SUB connectors. Contact function and control dictated by system software.
