The DAC-104 24-bit, 96-kHz
D-to-A Converter Module

The DAC-104 is a four-channel, 24-bit, 96-kHz Digital-to-Analog audio converter module for the System 1000 module frame. This is the first digital audio module for the heretofore totally analog System 1000.

• 4-channel, 24-bit, 96-kHz D-to-A conversion
• Two balanced audio outputs per channel, 8 total
• Adjustable Output Levels – Multi-turn trimmers – 1 trimmer per output — 20 dB Range
• Total jitter immunity!
• Phase Accurate D-to-A conversion across any number of channels
• THD+N = -102 dB (0.00079%) measured at -3 dBFS, any sample rate, any test frequency
• 4 power, 2 error, and 4 range indicating LEDs
• Polarity Invert function – jumper selectable
• L/R swap – jumper selectable
• L+R to L out, L-R to R out – jumper selectable
• L+R Sum to both L and R outputs – jumper selectable
• Automatic De-emphasis for 44.1, 48, 88.2, and 96 kHz when Pre-emphasis bit is set
• Front edge test points
• 165 mA quiescent draw @ ±15 V, 171 mA - full signal into a bridging load

Benchmark digital converters have a reputation for high-end performance without a high-end price tag. The DAC-104 is no exception. Most cardframe DACs lack a two-stage phase-lock-loop, making them very susceptible to jitter, the bane of digital audio. Those DACs can rarely achieve their rated performance in real world applications. The DAC-104, however, takes full advantage of our latest digital lockup technology to provide total jitter immunity and very high performance. Best of all, the rated performance is bullet proof: it is repeatable under the most adverse input signal conditions!

The DAC-104 has a THD+N of 0.00079% at -3 dBFS and an input sample-rate range of 28 through 108-kHz. Features include; auto-detection and processing of pre-emphasized digital audio, jumper selection of discrete stereo, matrix stereo (L+R and L-R), polarity inversion, and Mono sum on all outputs. Output level controls are at the front card edge and provide an analog output adjustment range of +7.5 dBu to +27.5 dBu at 0 dBFS.

The price of the DAC-104 is $1295. Call Rory Rall at 1-800-262-4675 for more information.
