To achieve this, pins 2 and 3 of an
XLR plug are being connected to
the two contacts of a Phono/RCA
plug. The ground shield of the cable
is only connected to pin 1 of the
XLR plug.
Using the AES input, a synchronization is again possible at half, quarter, double and quad
sample rates, see above.
8. Digital Outputs
8.1 AES – D-sub
The ADC Module provides the four AES/EBU outputs via a 25 pin D-sub connector. The D-sub
connector uses the widely known and often found pinout of the Tascam recorders (TEAC).
Therefore multicores D-sub to XLR can be ordered easily. These cable have 4 XLR outputs
male and 4 XLR inputs female. The inputs 2 to 4 are not used by the ADC Module.
Every output is transformer-balanced and compatible to all devices with AES/EBU port. The
format is set by DIP switch 6 to Professional or Consumer. If AES PRO is chosen, the output
level is almost 5V. If CON (Consumer) is chosen, the output signal will have a channel status
compatible to SPDIF, and the output level will be reduced to 2V.
Connecting devices with coaxial SPDIF ports to the ADC Module's outputs (the XLR Multicore)
is accomplished by simple cable adapters (XLR/RCA).
To achieve this, pins 2 and 3 of an
XLR plug are being connected to
the two contacts of a Phono/RCA
plug. The ground shield of the cable
is only connected to pin 1 of the
XLR plug.
The Channel Status of the ADC Module has been implemented according to AES3-1992
Amendment 4.
• 32* / 44.1 / 48 / 64* / 88.2 / 96 / 176.4 / 192 kHz according to sample rate
• Audio use
• No Copyright, Copy permitted
• Format Consumer oder Professional
• Category General, Generation not indicated
• 2-Channel, No Emphasis
• Aux bits Audio use, 24 Bit
• Origin: 8MIC
* This value is set automatically in external synchronization mode as soon as the sample rate is recognized.
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 active when sending data to a device with AES/EBU
input (when XLR connectors are used).
