Analog Audio Interfaces
Installation

The NV8900 product family includes 6 MADI interfaces:

• MADI to AES, unbalanced • AES to MADI, unbalanced

• MADI to AES, balanced • AES to MADI, balanced

• MADI to analog audio • Analog audio to MADI

 By AES we mean AES-3 and by MADI we mean “multi-channel audio digital interface,”

governed by standard AES10-2003.

The two analog audio interfaces are quite different from the AES interfaces and are discussed
under Analog Audio Interfaces

AES Interfaces

The two MADI-to-AES interfaces are demultiplexers that have one MADI input and 32 AES
outputs. The unbalanced outputs use 75W BNCs; the balanced outputs use 110W shielded
twisted pairs on DB25 connectors.

The two AES-to-MADI interfaces are multiplexers that have 32 AES inputs and one MADI output.
The unbalanced inputs use 75 W BNCs; the balanced inputs use 110W shielded twisted pairs on
DB25 connectors.

The MADI inputs and outputs are 75 W BNCs.

The AES-to-MADI interfaces accept up to 64 audio channels. The MADI-to-AES interfaces
produce 64 audio channels. The individual MADI channels are paired on the AES inputs or
outputs. AES connector 1 corresponds to MADI channels 0 and 1; AES connector 2 corresponds
to MADI channels 2 and 3, and so on. AES connector 32 corresponds to MADI channels 62 and

63.

The AES interfaces are 1RU and about 2″ in depth. The following photographs are
representative:

This is a front view of the AES (balanced) to MADI interface. The other AES units resemble this
one, where the difference between the models is the legend.

AES Interfaces

This is a rear view of the AES (balanced) to MADI interface:

It has 4 DB25 connectors supporting the AES inputs. The MADI to AES (balanced) interface is
similar, except for the legend.

This is a rear view of the AES (coax) to MADI interface:

Here, there are 32 BNC connectors supporting the AES inputs. Here, too, the MADI to AES (coax)
interface is similar, except for the legend.

Functions

The AES models convert discrete AES signal pairs to MADI format or vice versa.

The MADI-to-AES interfaces interpret the incoming framing data and preserve VUCP data.

The AES-to-MADI interfaces preserve VUCP and also generate the framing data (in the first 4 bits
of each MADI subframe).

Each interface has a video reference input (loop-through). Each interface has a serial port (DE9)
that is reserved for future use. Each interface has an Ethernet port (RJ-45) for a connection to
MRC (the Miranda Router Configurator).

Each interface has two power connectors (for PS0001 power supply) and a grounding terminal.

Rates

The MADI interfaces send and receive AES at exactly 48.0 kHz (samples per second).

Configuration

You can use MRC (Miranda Router Configurator) to change an NV8900’s IP address and also to
upload firmware.

The NV8900 has a 16-position rotary switch (Frame ID) on the front. This switch exists so that
different NV8900 frames can be distinguished (by MRC) on a network. The switch is not required
for operation.

Operation

The NV8900 AES interfaces function on their own and do not require an operator.

It is sufficient to rack-mount the devices and connect cables to your inputs and outputs.

Analog Audio Interfaces

The NV8900 analog audio interfaces are larger, and more complex than, the AES interfaces and
provide a number of status LEDs:

The MADI-to-analog-audio interface is a demultiplexer that has two MADI inputs and 64 analog
audio outputs (32 pairs). The outputs use 110 W shielded twisted pairs on DB25 connectors.

The MADI-to-analog-audio interface interprets the incoming framing data and preserve VUCP
data.

The analog-audio-to-MADI interface is a multiplexer that has 64 analog audio inputs (32 pairs)
and two MADI outputs. The inputs use 110 W shielded twisted pairs on DB25 connectors.

The analog-audio-to-MADI interfaces generate VUCP and also generate the framing data (in the
first 4 bits of each MADI subframe).

The MADI inputs and outputs are 75 W BNCs.

The analog-audio-to-MADI interface accepts 64 audio channels. The MADI-to-analog-audio
interface produces 64 audio channels. The MADI channels are paired on the analog inputs or
outputs.

There are 4 analog audio connector pairs on each of 8 DB25s at the rear of the unit, totalling 64
channels (or 32 channel pairs). Each channel corresponds to 3 pins on a DB25; each channel pair
corresponds to 6 pins. The analog channels are numbered consecutively on the 8 DB25s: 1–8, 9–
16, 17–24, and so on, up to 57–64. See Analog Audio Connectors

Each MADI unit has a video reference input (loop-through). Each interface has a serial port (DE9)
that is reserved for future use. Each interface has an Ethernet port (RJ-45) for a connection to
MRC (the Miranda Router Configurator).

Each unit has two power connectors (for PS0001 power supply) and a grounding terminal.

Each unit is 1RU and 17″ in depth.

Analog Audio to MADI Interface

This is a front view of the analog-audio-to-MADI interface:

This is a rear view of the analog-audio-to-MADI interface:

Function

The AA-to-MADI interface receives 64 analog audio inputs and produces two MADI outputs,
both identical. The second output is for redundancy.

The 64 inputs are paired internally and are represented by 32 LEDs at the front of the panel, one
for each pair. Each of these LEDs acts as a primitive level meter for the pair, according to the
following scale:

LED state Audio Level Range
