Q: When I record a file, the pitch is way off, either too slow
or too fast, what might be the cause?
A: The most likely cause is that the clock source in the Antex
Mixer has been set to a source that is no longer valid. This can
happen if you have disconnected your video clock source or if
you had been recording from a digital input source that is no
longer valid (disconnected or in Record). Open the Antex
Mixer, set the Clock Source to DSP. Play a file known to be
good using the Antex Demo and see if the problem is fixed.
Q: My record or playback channels suddenly got very
noisy, what might be the cause?
A: The Sample Clock Source may have input a glitch or
transient into the StudioCard and upset its clock source. Open
the Antex Mixer, set the Clock Source to DSP, then back to
your original settings, or from DSP to another setting. This
resyncs everything on the card.
Audio Quality Listed below are commonly asked questions about audio
quality.
Q: I know you gave all the jargon specs, but what kind of
audio quality are we talking about here?
A: The specs quoted are derived from Audio Precision (the
standard in audio) testing on each production unit. Antex has
been building high quality audio cards for many years and we
are confident that we offer the cleanest sound of PC based
add-in cards.
