Regulatory and Safety Notices FCC Notice Part 15 of the Federal Communication Commission Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference free radio frequency spectrum. Many electronic devices produce RF energy incidental to their intended purpose. These rules place electronic equipment into two classes, A and B, depending on the intended use. Class A devices are those that may be expected to be installed in a business or commercial environment.
equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at personal expense. Modifications The FCC requires the user to be notified that any changes or modifications made to Avid hardware that are not expressly approved by Avid Technology may void the user’s authority to operate the equipment.

Standard to which conformity is declared: (IEC 60825-1) Optical connections are located on the rear panel and are typically labeled “Optical” or “SPDIF/ADAT.
Disposal of Waste Equipment by Users in the European Union Rack-mount Requirements The following rack-mount requirements are listed below: • Elevated Operating Ambient — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment might be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
Lithium Battery Replacement If a battery is supplied in this Avid product it must only be replaced by qualified personnel. Contact Avid Customer Support for assistance. WARNING Danger of explosion if battery is incorrectly replaced. Replace with only the same or equivalent type recommended by the manufacturer.

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.
