Euphonix MADI Converters Operation Manual Chapter 1: Introduction 1.1 MI715/MO705 The MI715 and MO705 converters provide MADI conversion to interface to/from analog and AES equipment such as consoles, tape decks, microphone preamplifiers and other devices. Both converters are two rack spaces high and are housed in a stain‐ less steel chassis with machined, heavy aluminum front panels. The MI715 converts incoming analog signals to 24‐bit MADI digital signals that capture the input’s complete dynamic range.
Euphonix MADI Converters Operation Manual 1.2 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 Sample Rate and Sample Rate Source LEDs blink as the converter senses the incoming Sample Rate source and Sam‐ ple Rate. We recommend monitoring the power‐up sequence to verify the converters have correctly auto‐sensed the desired Sample Rate Source and Sample Rate. 1.
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, particular‐ ly when installed in a rack.
Euphonix MADI Converters Operation Manual Chapter Ϯ: MI715/MO705 Converters 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 Ϯ.ϯ MI715/MO705 Converters Features MI715/MO705 Front Panel This section discusses both front panels and notes their few differences. Trim Pots Access: One trim pot adjuss the maximum analog input/output level of channels 1–8 in 2‐dB steps between +12 and +26 dBu. SR Conv: This indicates sample‐rate conversion activity on the auxiliary digital inputs. Sample Rate LEDs: These LEDs indicate the sample rate to which the converter is cur‐ rently locked.

Euphonix MADI Converters Operation Manual MI715/MO705 Converters Features Ϯ͘ϲ S ynchronization Ϯ͘ϲ.1 MI715 The MI715’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 MI715 is powered on. The order in which external signals are tested for presence is: AES, Word, Internal.
