Converter Mode

ProFire 2626 can operate in two different ways while in Standalone Mode. Each mode is described separately below:

A/D – D/A Mode:

When this parameter is set to “A/D - D/A” mode the interface operates like a standard analog-to-digital (A/D), digital-to-analog (D/A), and S/PDIF format converter. The operation of this mode varies by the sample rate of the interface. This is described in detail below:

44.1-48 kHz

(Optical Port B can only be set to S/PDIF at these sample rates)

Analog In 1-8	ADAT (port A) Out 1-8
ADAT (port A) In 1-8	Analog Out 1-8
Coaxial S/PDIF	Optical S/PDIF
Optical S/PDIF	Coaxial S/PDIF

88.2-96 kHz (when Optical Port B is set to ADAT)

Analog In 1-8	ADAT Out 1-8*
ADAT In 1-8*	Analog Out 1-8

88.2-96 kHz (when Optical Port B is set to S/PDIF)

Analog In 1-4	ADAT Out 1-4
ADAT In 1-4	Analog Out 1-4
Coaxial S/PDIF	Optical S/PDIF
Optical S/PDIF	Coaxial S/PDIF

176.4-192 kHz

(Optical Port B can only be set to ADAT at this sample rate)

Analog In 1-4	ADAT Out 1-4**
ADAT In 1-4**	Analog Out 1-4

*When operating at 88.2/96 kHz (S/MUX II mode), four channels of audio are sent/received via ADAT port A while the remaining four channels are sent/received via ADAT port B.

**When operating at 176.4/192 kHz (S/MUX IV mode), two channels of audio are sent/received via ADAT port A while the remaining two channels are sent/received via ADAT port B.
