• AES Error Indication Type: There are two DIP switch

selectable modes of AES error detection that will create a RED

error indication in the AES Signal Error Indication LED on the

front panel;

1) Reception errors: errors in reception of data or no data

stream at all (S1=Down), or

2) Reception and data errors: errors in reception and data

errors identified by the sending device (possibly invalid)

(S1= Up). See Figure 1–4 for AES error DIP switch

settings.

• AES Input Connector: The AES/EBU IN input connector is meant to

receive standard AES/EBU signals. This female BNC connector is

configured for an unbalanced, 75 connection. Note that the unit will

monitor the

AES/EBU In input only when the Analog/Digital

Source Select

switch is set to Digital and the Digital Source

Select

switch is set to AES.

• AES Input Level Gain Calibration DIP Switch: Input Level Gain

Calibration, the analog level which corresponds to a given digital

input value, is settable via this DIP switch. The factory setting is +4

dB (analog) = -20 dBFS (digital). See the silk-screened chart on the

rear panel or the diagram below for gain calibration settings.

Note

Position 3 is not used.
