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 it 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 your Echo hardware transmits. To access this switch go to the Console.

Select Preferences under the File menu. In the window that appears you’ll see a

pair of check boxes in an area labeled S/PDIF Out Format; one box is labeled

Consumer and the other Professional. 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 click the OK button and again try recording to your DAT.

Note: Your Echo card never transmits the SCMS bit, regardless of which

mode is selected.

Problem: When the Windows start-up sound plays, it plays at an altered pitch.

Solution: When your Echo card is set to sync with an external device, it will

playback at the rate generated by that device. If the startup sound you are using

was sampled at 8kHz, but you are synchronized with a device running at 44.1kHz,

the startup sound will play back at this faster rate. You have four choices - ignore

the altered pitch, switch to internal clock, use the sample rate lock feature, or use a

different device for the startup sound playback. We suggest that you never use

your Echo card for playback of any of Windows’ system sounds.

Problem: Your Echo card doesn’t seem to recognize the synchronization clock to

which it is connected.
