When using the Digital Out, make sure the input device is set to the same sample frequency as
the AP25 and that it’s clock source is set to input. Sample rate choices are 48kHz, 96kHz, and
192kHz. Select the highest rate supported.
2.5 Chassis Rack Mounting and Connection
The AP25 chassis requires 3U of standard rack space for proper mounting.
Caution:
Because power line surges can damage the AP25, we require the use of a properly
functioning computer-grade surge /spike suppressor. We also recommend using an
uninterruptible power supply (UPS).
1.
Install the AP25 into the audio rack, securing it properly with rack screws.
2.
Connect the AP25 to other equipment (see appendices: A Connector Pin-outs, B Interface
Wiring Diagrams, and C AP25 Wiring and Block Diagrams).
3.
Connect the supplied power cable between the AP25 unit and the AC mains source.
