analogue outputs

Output Levels: 2V rms or 6V rms on all outputs, set by the Output Level switch on the rear panel.

Balanced Outputs - 1 stereo pair on 2x 3-pin male XLR connectors.

These outputs are electronically balanced and floating, the signal balance ratio at 1kHz is better than 40dB Output impedance is 3?, maximum load is 600? (a 10k? load is recommended).

Unbalanced Outputs - 1 stereo pair on 2x RCA Phono connectors. Output impedance is 52?, maximum load is 600? (a 10k? load is recommended).



digital I/O

INPUTS

USB interface on a B-type connector, will accept up to 24 bit PCM at 44.1, 48, 88.2,96, 176.4 or 192kS/s. Operates in asynchronous USB mode.

2x AES/EBU on 3-pin female XLR connectors. Each will accept up to 24 bit PCM at 32, 44.1, 48, 88.2 & 96kS/s OR as a Dual AES pair at 88.2, 96, 176.4 & 192kS/s.

2x SPDIF on 1x RCA Phono and 1x BNC connector. Each will accept PCM at 32, 44.1, 48, 88.2 or 96kS/s up to 24 bits.

word clock I/O

INPUT

Word Clock Input on 1x BNC connector. Accepts standard word clock at 32, 44.1, 48, 88.2 & 96kHz. The data rate can be the same as the clock rate or an exact multiple (0.5x, 1x, 2x, 4x) of the clock rate.
Sensitive to TTL levels.

clock frequencies
N/A
residual noise
Better than -110dB0 @ 20Hz - 20kHz unweighted. (6V Setting).
spurious responses
Better than -110dB0 @ 20Hz - 20kHz unweighted.
filters
PCM Mode - 2 filters on Debussy give different trade-offs between the Nyquist image rejection and the phase response.
Filter 1 is a "Classic" sharp filter with linear phase and pre-ringing, while Filter 2 is an asymmetrical "Apodizing" filter with non-linear phase and no pre-ringing.
