MIDI Input and Output
5-pin female DIN connectors accept or deliver MIDI signals. The ADA8824
(ADAT) uses MIDI for control when not being operated in stand-alone or ADAT
Sync modes. The ADA8824 (ADAT) uses Sysex commands for control.
AES/EBU Inputs
XLR-3 female connector. This connector accepts digital audio
signals using the AES-3 protocol (which includes older AES/EBU
signals). The connectors are paired (marked 1-2, 3-4, etc.) because
each AES-3 signal represents two digital audio channels.
Inputs 1-2, 3-4, or 5-6 are also used for external AES/EBU sync
inputs.

NPUTS
XLR-3 female connector. This
connector accepts analog audio
signals from balanced or unbal-
anced sources. The input imped-
ance is 20-kilohms, balanced
(diff-amp input). The maxi-
mum input level is +25 dBu. This connector should be driven from a low source impedance.
Analog Outputs
XLR-3 male connector. This
connector delivers balanced audio
signals from a 320-ohms source.
The output stage emulates a
grounded center-tap transformer.
The maximum output level is
+25 dBu For unbalanced loads, either float the unused output pin (usually pin 3), or ground it at the
ADA8824 (ADAT). Floating pin 3 is the preferred method.
AES/EBU O
UTPUTS
XLR-3 male connector. This connector delivers digital audio
signals using the AES/EBU. The connectors are paired (marked 1-
2, 3-4, etc.) because each AES/EBU signal represents two digital
audio channels.
