implemented in devices that are likely to be used in professional recording
environments, whereas the consumer mode is commonly implemented on
equipment designed for home use in the consumer market. The primary
difference between the two modes is in the implementation of the SCMS
copy protection bit, which, in the consumer format, prevents the user from
making digital copies of a digital copy. In most professional equipment, this
copy protection bit can be turned off or on according to the user’s needs. In
consumer products, the SCMS bit is always enabled.
Unfortunately there is no way for the transmitting device to automatically
detect which format the receiving device is able to accept. If you have a
DAT deck that is not able to read the S/PDIF output from your Echo card,
chances are the card is transmitting in the mode that the deck is not
equipped to handle.
We have provided a software switch in the driver that allows you to select
which mode transmits. To access this switch go to the Console. In the
Options menu select either S/PDIF Pro or S/PDIF Consumer. Select the
appropriate format for your DAT (if you don’t know which one to use,
simply select the one that is not currently checked). Now try recording to
your DAT again.
Important note: No Echo product transmits the SCMS bit; regardless of
which mode is selected.
Problem: When you play an audio file, it plays at an altered pitch.
Solution: When your Echo card is set to sync with an external device, it will
play back at the rate generated by that device. If the sound you are playing
was sampled at 11kHz (for example), but you are synchronized with a
device running at 44.1kHz, the sound will play back at this faster rate. You
have four choices - ignore the altered pitch, switch to your Echo hardware’s
internal clock, change the sample rate of the external device, or use a
different device for the sound playback.
