The front of the ADI-8 DS features 16 LED level meters, six select keys and 27 LEDs providing
a detailed status display.
The analog input sensitivity can be changed in the area A/D REFERENCE.
In A/D STATE 8 level meters show the digital input level per channel.
The LEDs in A/D OUTPUT indicate which digital output currently carries the signal of the analog
to digital conversion. With Patch Mode active the analog input signal is in some cases not avail-
able on the digital outputs ADAT and AES.
The comprehensive PATCH MODE turns the ADI-8 DS into a format converter, distributor and
router, adding many advanced functions to the basic AD and DA conversion.
In the CLOCK SECTION the current clock reference and frequency multiplier is chosen.
The digital input signal of the DA-converters is chosen by pushing the D/A INPUT button.
In D/A STATE 8 level meters show the digital input level per channel.
D/A REFERENCE defines the analog reference level of the analog outputs. This level is
reached at full scale of the DA-converters, thus matching the front panel level meter's level indi-
cation.
The rear panel of the ADI-8 DS has eight analog inputs, eight analog outputs, mains power,
word clock I/O, and the digital inputs and outputs AES and ADAT.
ANALOG INPUTS: Eight balanced Line inputs, 1/4" TRS inputs and D-sub.
ANALOG OUTPUTS: Eight balanced Line outputs, 1/4" TRS outputs and D-sub.
AES I/O (25-pin D-sub): The D-sub connector provides four AES/EBU outputs and four
AES/EBU inputs. The 25 pin D-sub connector is wired according to the widely spread Tascam
standard (pinout see chapter 12.5). The AES I/Os are transformer-coupled. The high sensitivity
type input accepts all common digital sources, even SPDIF.
ADAT I/O MAIN (TOSLINK): Standard ADAT optical port.
ADAT I/O AUX (TOSLINK): Transmits further channels at activated sample multiplexing.
WORD IN (BNC): A push switch allows to activate internal termination (75 Ohms).
WORD OUT (BNC): Standard word clock output.
IEC receptacle for power connection. The specially developed, internal hi-performance switch
mode power supply lets the ADI-8 DS operate in the range of 100V to 240V AC. It is short-
circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations, and sup-
presses mains interference.
