The AD-16 is equipped with four optical ADAT outputs that can operate at sample rates up to 96 kHz. When using 44.1 or 48 kHz, only the first and third optical outputs are needed. The first output goes to the first ADAT port on the 9652 card which is located right next to the 9-pin connector. This is for channels 1-8. The third optical output of the AD-16 will go into the third port from the left of the 9-pin connector on the Nuendo 9652 card. This is for channels 9-16. When using 88.2 or 96 kHz, the number of ADAT optical channels is cut in half. So the first ADAT output will send channels 1-4, the second output will send channels 5-8, the third output will send 9-12, and the fourth output will send channels 13-16. The Nuendo 9652 card acts in the same way. So the first optical port is 1-4 (located next to the 9-pin connector). The third optical port from the 9-pin connector is input 5-8. The supplied daughter card for the Nuendo 9652 card is where you will attach the ADAT optical cable for channels 9-12. The Nuendo 9652 card, when using sample rates of 88.2 or 96 kHz, can only accept 12 channels. To have more channels at that sampling rate you must have two of these cards present in your system.

On the rear of the AD-16 is a series of trim pots for each channel. Insert a +4 analog signal into each channel and output the digital signal to your audio application or metering device. You should see the level at -16dBFS which is the default level from the factory. To calibrate for a -12dBFS slowly turn the trim pots for the desired channels until the external device reads -12dBFS on it's meters.

The AD-16 has word clock output which can be sent to the daughter card of the Nuendo 9652 card which has word clock input. There is a control panel for the Nuendo 9652 card. There should be a setring for the clock source. Set it to word clock. When using sample rates of 88.2 or 96 kHz, it is important to set dip switch #5 to the up position, as the Nuendo card needs to see a 44.1 or 48 kHz sample rate. When using 44.1 or 48 kHz sample rates, dip switch #5 should be in the down position.

The D-Sub connector is a 25-pin breakout cable that either has eight XLR or 1/4" balanced connectors on the other end. The pinout is the Tascam analog format.

The AD-16 has an optional AES output card which sends all sixteen channels of AES through it. You will need to purchase the AD-16 AES cable and connect this to the AES inputs on the HD converters. At this point you will need to set the HD converters to clock from the incoming AES signal.

The optional card can be installed by removing the lid of the AD-16, then removing the hex screws holding in the blank panels for the optional card slot. Due to the design of the unit, you will need to loosen all hex screws on the back to allow the rear panel to flex out a little. The option card comes with a standoff which will be needed to help keep the card in place. In front of the headers on the main board there is a screw which will need to be removed and the standoff put in it's place. Once the standoff has been put installed, place the card so that it aligns with the open option slots on the rear panel and fit it into the block headers on the main board. The screw that was removed from the main board will now be used to screw in the option card to the standoff. Replace and tighten the hex screws on the rear panel and close the lid.
