Example 2: Only the outputs of the DIGIs are connected to other devices.

Connect the internal Sync-Out of the master card to the Sync-In (CD-ROM) of the second card,

activate its internal input and AutoSync mode. Next connect the third card in the same way,

from the second's card Sync-Out to the third's card Sync-In. Configure this card like the second

one. The necessary 2-wire cables are the ones supplied with the DIGI cards. Of course this

method is also operational with the external connectors, like optical or coaxial, as long as the

corresponding input is activated.

Please note when using more than one card plus the word clock output that only one card

can be master!

11. Special Features of the Digital Output

Apart from the audio data itself, digital audio signals in SPDIF or AES/EBU format include a

header containing Channel Status information. False Channel Status is a common cause of

malfunction. The DIGI32 series ignores the received header and creates a totally new one for

the output signal.

Note that in record or monitor modes, set emphasis bits will disappear. Recordings original-

ly done with emphasis should always be played back with the emphasis bit set!

Emphasis is used very seldom. In case you have to work often with such material we recom-

mend our DIGI32 PRO. It allows to set emphasis active on the outgoing data while liste-

ning to the result of this operation.

The outgoing status data of the DIGI32 has, with regard to other digital appliances, been

optimized to the largest compatibility possible:

• 32 kHz, 44,1 kHz, 48 kHz according to the sample frequency

• Audio use

• No copyright, copy permitted

• Format Consumer or Professional

• Category General, generation not indicated

• 2-Channel, No emphasis

• Aux bits audio use

Professional AES/EBU equipment can be connected to the Hammerfall DSP thanks to the

transformer-balanced coaxial outputs, and the ‘Professional’ format option with doubled output

voltage. Output cables should have the same pinout as those used for input (see section 8.1

‘Connections’), but with a male XLR plug instead of a female one.

Note that most consumer-orientated equipment (with optical or phono SPDIF inputs) will

only accept signals in ‘Consumer’ format!

The status 'Professional' should always be activated when using AES/EBU format (when XLR

connectors are used).
