Crystal Vision Introduction
1Introduction
Designed for transporting a large amount of audio as a block, MADI (AES10) is an audio
signal format used for getting many channels of audio down a single coax cable, with these
multiple AES streams packed together and sent with a higher data rate.
The MADDA105 and MADDA111 audio distribution amplifiers take in a MADI (AES10) data
stream usually containing up to 64 mono audio channels and create multiple copies of this
data stream which can then be sent to different places.
MADDA105 has five outputs and MADDA111 has 11 outputs to provide audio distribution to
all audio areas.
MADDA105 and MADDA111 support the industry standard payload of 64 channels at a
sampling rate of 48 kHz, with sampling rates up to 96 kHz also supported for those requiring
fewer channels in return for the cleanest possible sound.
MADDA105 and MADDA111 include useful signal monitoring, providing both LED and GPI
output indication of signal presence, as well as on-board power supplies fault.

Crystal Vision Introduction
The MADI distribution amplifiers fit in Crystal Vision’s Indigo frames (available in 2U, 1U and
desk top box sizes) alongside the other products and offer a choice of rear modules to suit
your budget and application.
MADDA105 is a space-saving 100mm x 266mm module which sits in one frame slot allowing
up to 12 MADI DAs in 2U. It uses the RM41 or RM67 frame rear modules to access the one
MADI input and five MADI outputs.
MADDA111 is a ‘double decker’ 100mm x 266mm module which sits in two frame slots
allowing up to six MADI DAs in 2U. It uses either the RM41 and RM34 frame rear modules
together or the RM67 and RM34 rear modules together to access the one MADI input and
eleven MADI outputs.
MADDA105 and MADDA111 meet the AES10-2008 specification and allow 56 channels at
sample rates from 32 to 48 kHz with a tolerance of ±12.5%, a nominal 64 channels at sample
rates from 32 to 48 kHz, and 28 channels at sample rates from 64 to 96 kHz with a tolerance
of ±12.5%.
The universal connection system allows a mixture of Crystal Vision modules in the frame.
The modules plug in the front and the rear connectors plug in the rear. Depending on frame
design, a hinged or removable front panel reveals LED indications of input present and PSU
status when opened.

MADDA105 card
MADDA111 card with piggyback board
2.1 Card installation
The MADDA105 and MADDA111 distribution amplifiers fit into all Crystal Vision rack frames.
All modules can be plugged in and removed while the frame is powered without damage.
Indigo frames have card retention brackets which must be unscrewed to allow access to the
board carriers (see Indigo frame manual for more details). The brackets should be re-fitted,
particularly so for mobile installations.
Make sure that the correct rear module for the card is fitted. Note that the MADDA111 has a
piggyback board and two rear modules need to be fitted in the correct order – see section
Rear module connections.
Ensure that the boards are correctly fitted into both card guides and press firmly home using
the plastic card handle.
2.2 Rear module installation
Firstly, remove the EMC covers from the rear module slot position. Fit the rear module onto
the frame rear connector and screw into position. Ensure the rear module is in the correct
slot. When viewed from the rear, slots number from top to bottom and right to left. Slot one is
the top right slot. See Indigo frame User Manual for more information.

The 2U Indigo 2 frame will house up to 12 single height modules or six dual height modules
and dual power supplies. The 1U Indigo 1 frame will house six single height modules or three
dual height modules and a single or dual power supply. The Indigo DT desk top boxes have a
built-in power supply and will house up to two single height modules or a single dual height
module.
Note: For details of fitting rear connectors please refer to the appropriate frame manual.
MADDA105 can support the following rear modules: RM41 and RM67. The RM41 has a
single MADI input and five MADI outputs and the RM67 has the same number of inputs and
outputs but includes relay bypass whereby the MADI input is automatically routed to one of
the outputs in the event of power failure. Both rear modules are single height.
MADDA111 supports the RM41 and RM67 but in addition must use the RM34 rear module to
accommodate the plug in card that provides the additional outputs. The combination of RM41
+ RM34 or RM67 + RM34 make a combined double height rear module. The RM34 rear
module must always be fitted in the top position.

The external GPI control lines 'a' to 'f' at the frame remote connectors are provided to allow
remote control and/or remote status indication. Line 'a' is assigned as a GPI output to provide
remote indication of input presence.
The GPI output is fitted with 6800 ohm pull-up to +5V and 270ohm series resistor so it can
drive an LED directly. If the series resistor is shorted out, it can drive a bulb at +45V 500mA
max.
