2.6.1AM713

The AM713’s Sample Rate is set externally by one of two source signals or internally by crystals and associated circuitry. The Sample Rate Source is determined automati- cally by the presence of signals when the AM713 is powered on. The order in which external signals are tested for presence is: AES, Word, Internal.

The detected signal immediately becomes the source for the AM713’s sample rate clock. The auto-sensed Sample Rate Source can be overridden using the button on the front panel of the AM713, below the Sample Rate Source LEDs. If neither AES nor Word Clock signals are present, the AM713 uses its internal clock driven by crystals.

The default internal Sample Rate of the AM713 is 48 kHz. This default internal rate can be overridden with the Sample Rate button on the front panel of the AM713 (directly below the Sample Rate LEDs) to 44.1, 48 or 96 kHz.

2.6.2MA703

The MA703 detects Sample Rate and Sample Rate Source like the AM713 with the following differences:

•Since the MA703 is always a slave to an external Sample Rate Source, there is no internal Sample Rate Source setting.

•The MA703 can use MADI in addition to AES or Word Clock as a Sample Rate Source, and detects the presence of these signals in the following order: AES, Word, MADI.

When a signal is detected, it immediately becomes the sample rate clock of the MA703. The auto-sensed Sample Rate Source can be overridden with the Sample Rate Source button on the front panel of the MA703, below the Sample Rate Source LEDs.
