Digital Interface
The Joemeek Digital Audio Interface provides high quality
digital audio outputs, compatible with most digital recorders,
as well as Digital Audio Workstations and digital mixers.
S/PDIF format is available from both the optical
and the RCA phono connectors.
The Joemeek Digital Interface has highly stable onboard master clocks
for low-jitter, hi-fi results. Internal sample rates of 44.1kHz,
48kHz, 88.2kHz or 96kHz are selected by means of rear panel
switches. 44.1kHz is the standard used for audio CD's, while
48kHz and 96kHz are widely used in recording studios. In
general, the higher the sample rate, the better the audio
fidelity, but the more disk space is required for the recording.
For example, recording at 96kHz requires twice as much storage
as 48kHz. Consult the manual of your recorder or DAW as to
what sample rates it will accommodate.
To avoid distortion, care should
be taken not to overdrive the input to the Digital Interface.
The red LED at the top of the VU bargraph meter is labeled "PEAK
FSD" which stands for "Full
Scale Digital". Occasional flashes are OK but if it is on
all the time, turn something down!
