PRODUCT DATA SHEET
ProBox 15
24bit-96kHz Delta-Sigma
D/A Converter
The Probox 15 uses the latest surface mount technology to
provide a cost effective, high quality D to A converter, using
delta-sigma technology to give an up to date, very linear phase
response DAC. The result is a smooth, transparent sound of
exceptional quality with an analogue noise floor of < -117dB
and a distortion measurement of < 0.0016%
AES, Co-axial (phono) and Optical inputs are provided with
front panel input selection. A fully regenerated AES output of
the AES input signal, including Status and User subcodes is fed
to a separate connector (loop through) on the rear panel. Full regeneration provides a lower jitter than simple electrical
buffering can provide.
The analogue outputs are electronically balanced and have a
variable output range from 0dBm to + 20dBm (via multi-turn
presets accessed through the rear panel). Audio Line Output
Transformers may be fitted as an optional extra.
Status LED's on the front panel indicate:a) whether the digital input has locked to a good incoming signal
b) if pre-emphasis is present - note that the signal is then deemphasised digitally for correct analogue output.
c) if data errors occur resulting in high CRC, parity or bi-phase
coding errors.
d) sample rate - 32kHz, 44.1kHz, 48kHz, 88.2kHz or 96kHz
The front panel controls can be "locked out" via a recessed slide
switch, to prevent operational or accidental tampering.
