INPUT MODE

This function allows selecting the physical input connector according to the audio source feeding the amplified
controller:

An analog audio source connects to the IN A and/or IN B inputs of the ANALOG panel (see Figure 7).
In this case activate the analog inputs selecting the ANALOG input mode.

A digital audio source connects to the AES/EBU IN input of the AES/EBU panel (see Figure 7).
In this case, activate the digital inputs selecting the AES/EBU input mode.
To select the input mode follow these steps (see Figure 32):
 From the main menu select INPUT SETTINGS and press the OK key or the encoder wheel.
Turn the encoder wheel to select INPUT MODE and press the OK key or the encoder wheel.

Turn the encoder wheel to select ANALOG or AES/EBU.

 Press the OK key or the encoder wheel to validate the setting (or ESC to abort).
In Figure 32 the AES/EBU input mode has been enabled. LOCK 44k1 is a status message indicating that the AES/EBU
input mode is active and that the digital audio source provides signals of sampling frequency of 44.1 kHz.
The LOCK status is obtained under the following conditions: a digital audio source is connected to the AES/EBU input,
the signal delivered by the source has a format supported by the controller's digital audio card, and no loss or fault is
being detected during data transfer.
If these conditions are not fulfilled the status will turn to LOCK-WARN or UNLOCK. The LOCK-WARN status (see
Figure 33 left) indicates that the incoming digital signal has a sampling frequency out of the nominal range that does not
lead to sound cut. On the contrary, the UNLOCK status (see Figure 33 right) indicates a faulty digital signal leading to
sound cut.
