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
stainless 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. Each main AES/EBU input is automatically evaluated
for sample-rate conversion. The incoming sample rate is compared with the internal rate. If they are the same, no conversion occurs. If the rates differ, sample-rate conversion is activated and persists until a new input is applied or the internal
sample rate changes. The sample-rate conversion range is
32–56 kHz.In addition to the 8 XLR connectors for analog inputs and 8 XLR connectors/2 D-Sub connectors for AES inputs. The MO705 converts incoming MADI signals to 8 analog
channels and 8 AES stereo pairs. The main 24 outputs can be
bit-depth converted from 24 to 20 or 16 bits.
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 Sample Rate. We recommend monitoring the power-up
sequence to verify the converters have correctly auto-sensed
the desired Sample Rate Source and Sample Rate.
Safety and Precautions
220, 230, 240 VAC Operation
Before connecting power to the converters, change the
fuse and voltage selector to the appropriate
220/230/240 VAC settings.
The converters preserve their signal quality using linear power
supplies that must be manually switched between 115 and
230 VAC. The units are shipped set for 115 VAC. Move the red,
two-position switch near the power entry module of the converters to the 230 VAC position (down) for 220/230/240 VAC
operation.
Each unit uses a 0.630 A fuse for 115 VAC operation. To operate at 220, 230, or 240 VAC, install the spare 0.315 A fuse provided in the power entry module fuse-holder.
To access both the active and the spare fuse:
1 Power off the unit.
2 Remove the IEC power cable from the power entry module.
3 Use a small screwdriver to open the fuse tray below the elec-
trical inlet.
The active fuse is to the rear of the tray. The spare fuse is in the
tray slot closest to the front. Pull the fuses through the plastic
constriction point that holds them from falling out.
Never disconnect the safety ground to the
converters.
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. The
MI715 and MO705 converters in particular should have space
left above and below every two units so heat can properly
dissipate.

Chapter 2: MI715/MO705 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.
The analog inputs and outputs can be calibrated from the
front panel of each unit.
AES/EBU and Word Clock external sync inputs on both units
provide synchronization to digital systems. Sample Rate
Source and Sample Rate are automatically sensed by both
units. Supported sample rates include 44.1, 48, 88.2, and 96
kHz. In addition, pull-up and pull-down rates for the standard
sample rates, as well as custom sample rates are available.
Applications
In addition to their standard use in a digital system, the MI715
and MO705 can be used as stand-alone converters. When used
with th e SH61 2 Studio Hub, this is a powerfu l conversion and
MADI routing system that can be used to interface between an
analog console and an otherwise all-digital facility (such as a
TV broadcast facility).
MADI cables can be extended to 50 m (164 ft),
allowing remote location of the converters.
MI715/MO705 Front Panel
This section discusses both front panels and notes their few
differences.
Trim Pots Access One trim pot adjusts 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 currently locked. Sample rates are
auto-sensed but can be manually selected on the AM713. Supported sample rates are 96 kHz, 88.2 kHz, 48 kHz, 44.1 kHz,
and Custom rates from external sources.
Sample Rate Source LEDs These LEDs indicate the format of
the Sample Rate Source to which the converter is currently
locked. Sample Rate Source can be auto-sensed or manually selected. If an external source is not detected, the MI715 reverts
to Internal sync; the MO705 mutes its outputs. If a manually
selected source is not present, the Sample Rate Source indicator blinks.
• AES: Sample Rate locked to AES Input.
• Word: Sample Rate locked to Word Clock Input.
• Internal (MI715 only): Sample Rate locked to its own internal crystal.
• MADI (MO705 only): Sample Rate locked to MADI.
• Auto: Sample Rate Source has been auto-sensed.
These LEDs appear in the same order in which signals are
tested for their presence. This detection procedure occurs
when the converters are powered on. The Sample Rate (MI715
only) and Sample Rate Source can also be selected manually.Manual Selection Buttons: The button below each Sample
Rate LED row manually selects the sample rate. The MI715
also allows manual selection of the Sample Rate Source.
Power Switch On/Off switch.
There are no user-serviceable parts in the converters.

Synchronization
MI715
The MI715 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.
The detected signal immediately becomes the source for the
MI715 Sample Rate clock. The auto-sensed Sample Rate Source
can be overridden using the button on the front panel of the
MI715, below the Sample Rate Source LEDs. If neither AES nor
Word Clock signals are present, the MI715 uses its internal
clock derived from on-board voltage-controlled crystal.
The default internal Sample Rate of the MI715 is 48 kHz. This
default internal rate can be overridden with the Sample Rate
button on the front panel of the MI715 (directly below the
Sample Rate LEDs) to 44.1, 48 or 96 kHz.
AES Sync Thru (male XLR) Outputs the same signal connected
to AES Sync In.
Word In (BNC) Master clock input for the converter when using Word Clock as Sample Rate Source.
Word Out (BNC) Outputs a Word Clock signal synchronized to
the Sample Rate Source. In the presence of an external Word
clock input, this connector provides a regenerated version of
the input signal. Without an external sample rate source, this
connector outputs an internally generated clock signal.
MADI In (BNC) Digital audio signal input.
• 1–8: Analog outputs
• 9–24: AES outputs
MO705
The MO705 detects Sample Rate and Sample Rate Source like
the MI715 with the following two differences:
• Since the MO705 is always a slave to an external Sample
Rate Source, there is no internal Sample Rate setting.
• The MO705 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 MO705. The auto-sensed Sample Rate Source
can be overridden with the Sample Rate Source button on the
front panel of the MO705, below the Sample Rate Source
LEDs.
