1. INSTALLATION
The PR8MK2 ADAT Option is very easy to install. Nonetheless we recommend that you
have an authorized technician install the module. We are not responsible for any damages that occur due to improper installation.
• Turn off power to the PR8MK2 and remove the mains power cable from its socket.
unit.
• Remove the screws from the top of the unit and remove the metal cover so you have
access to the unit.
• Insert the PR8MK2 ADAT Option into the installation slot and use the screws to secure
it to the back wall of the PR8MK2 housing.
• You are required to connect two (2) ribbon cables from the newly installed module to the
main board of the SM PR8MK2. One cable is to supply power to the PR8MK2 ADAT
Option board, and the other is to provide the 8 x channels of audio to the ADAT stream.

with the switch provided. If you require external clock sync, simply connect your sync cable to the word clock input. If
-
1/ Connect the 8pin flat ribbon cable between the 8pin configuration marked “digital out” on the PR8MK2 main board to the
8pin configuration towards the rear of the PR8MK2 ADAT
Option board. Ensure that pin 1 is connected to pin 1 by lining
up the red indicator market on the cable to pin on at both ends
of your connection.
2/ Connect the 3pin power source cable by connecting one end
to the configuration marked “digital power” on the PR8MK2
main board, and the other end to the 3pin configuration on the
new PR8MK2 ADAT Option board marked “+5v GND -5v”.
Ensure that the orientation of the cable is such that the +5v
indicators match up.
• Replace the top cover and screw it back in place.

2. CONNECTIONS
2.1 Digital ADAT connector
The PR8MK2 ADAT Option has one 8CH ADAT optical output. Remove the black plastic plug to access the optical
connector. This is where you connect your optical cable.
2.2 Sampling rate selector switch
There is a physical sample rate selector switch on the face of the PR8MK2 ADAT Option that allows selection of
either 44.1kHz or 48kHz operation. Use this switch to toggle between your desired sample rate setting. The nondepressed state of the switch sets a 48kHz sample rate, whereas a depressed state selects 44.1kHz operation.
2.3 Word Clock Sync Connectors
The PR8MK2 ADAT Option is always the sync clock master unless you connect a word clock sync cable to the provided BNC sync connector. If you require the master clock to be set by another device, simply connect a sync cable
to the word clock input. The ADAT option board will automatically detect sync and lock to the external clock source.
There is also word clock output for sending master clock sync data from the unit.
3 Application & Operation
3.1 The purpose of the PR8MK2 ADAT Option
The ADAT module allows you to output the SMPR8MK2’s 8 channels digitally via an optical cable to any ADAT compatible input device such as digital mixer, audio card, etc. This is perfect for adding additional inputs to many solutions. Simply connect your ADAT light pipe cable from the ADAT output on the ADAT option board module to the
ADAT input on your desired destination device (mixer, audio card, etc). Select the appropriate sample rate setting
you would like the PR8MK2 ADAT Option to be the clock master for your digital system, simply connect a sync cable
from the word clock output to you sync destination.
