Alesis EC-1 A ES/EBU instruction

Appendix E, EC-1 AES/EBU Interface

Note: The above illustrations assume that the source tracks of the M20 are set to receive digital input (as shown by a “D” under the meter for each track).

IF THE INPUT SELECTION IS ANALOG AND AES/EBU

SIMULTANEOUSLY:

If you have INPUT SELECT configured for analog and AES/EBU input, input routing must use the one-to-one configuration. This is the case because using any other bus configuration will route the selected I/O card digital source tracks (e.g. tracks 1 and 2 using odd/even routing) to all input enabled tracks even when the input enabled tracks are set to analog input, i.e., all input enabled tracks become I/O card destination tracks.

EDITING INPUT ROUTING WHEN THE INPUT SELECTION IS ANALOG

AND AES/EBU SIMULTANEOUSLY:

If you have INPUT SELECT configured for analog and AES/EBU input, editing the input routing is limited to selecting I/O card source tracks only. The analog input routing will not be editable and will follow (be the same as) the I/O Card routing. If the you want to edit analog input routing, the digital source cannot be I/O Card.

The scenario below describes a mixed signal input using I/O CARD as the digital source:

Example: You are recording a digital submix patched into AES/EBU input pair 1/2 and intend to route this input to channels 3 and 4. You also have an analog submix patched into the analog inputs for channels 7 and 8. The M20 is configured as follows: The DIGITAL SOURCE is I/O CARD. INPUT ROUTING uses the "odd/even" configuration (channels 1 and 2 are the digital source tracks). INPUT SELECT is set to DIGITAL input for channels 1 through 4; and ANALOG input for channels 5 through 8. Channels 3, 4, 7 and 8 are input enabled.

Channels 3 and 4 will monitor the AES/EBU input as expected (the “D” under each meter seems to make this obvious). Channels 7 and 8 will also monitor AES/EBU input (not the direct analog input) because the M20 is being told to bus channels 1 and 2 to ANY input enabled track(s). You cannot use odd/even or half & half input routing with AES/EBU input and monitor analog inputs simultaneously. To monitor the analog inputs for channels 7 and 8 together with AES/EBU input, INPUT ROUTING must use the one-to-one routing configuration. In this case however, AES/EBU input into channel pair 1/2 will not route to channels 3 and 4.
