IMPORTANT SAFETY INSTRUCTIONS The lighting flash with arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electrical shock to persons. The exclamation point within an equilateral triangle, is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.
13) Unplug this apparatus during lightning storms or when unused for long periods of time. 14) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

Euphonix MADI Converters Operation Manual Chapter 1: Introduction 1.1 AM713/MA703 The AM713 and MA703 converters provide MADI conversion to interface to/from analog equipment such as consoles, tape decks, microphone preamplifiers and other analog devices. Both converters are two rack spaces high and are housed in a stainless steel chassis with machined, heavy aluminum front panels. The AM713 converts incoming analog signals to 24-bit MADI digital signals that capture the input’s complete dynamic range.
Euphonix MADI Converters Operation Manual 1.3 Introduction Power On Sequence We recommend powering up the converters only after verifying the presence of a valid sync signal. After powering up the converters, the meter LEDs flash briefly and the Sample Rate and Sample Rate Source LEDs blink as the converter senses the incoming Sample Rate source and Sample Rate.
Euphonix MADI Converters Operation Manual Introduction Power Cord Requirements The converters are supplied with North American IEC power cords. If this cord is changed to allow a different plug configuration, it is the responsibility of the user to select an approved power cord with proper construction material, current capacity, flexibility, and strength characteristics. Cooling We strongly recommend providing adequate ventilation to the converters, particularly when installed in a rack.

Euphonix MADI Converters Operation Manual Chapter 2: AM713 and MA703 Converters 2.1 Features Professional grade audio conversion is accomplished utilizing 128 times over-sampled noise-shaped delta-sigma techniques. The analog to digital conversion employs a multi-bit modular architecture while the digital to analog conversion employs a single-bit modulator architecture. Low-jitter reference clocks are provided utilizing digital PLL techniques with VCXO and VCO oscillators.

Euphonix MADI Converters Operation Manual 2.6 Synchronization 2.6.1 AM713 AM713 and MA703 Converters 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 automatically 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.
