Get access to all your audio everywhere

Ideal for broadcasters who require access to all their audio everywhere, the MADDA111 distribution amplifier takes in a MADI data stream usually containing up to 64 mono audio channels and creates up to eleven copies of this data stream which can then be sent to different places.

MADDA111 is perfect for any applications where you need to transport a large amount of audio as a block - especially if you are already using other Crystal Vision products, with it fitting in the standard frames.

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. MADI makes it very easy to have a very flexible audio system by providing all your areas with 'raw' audio channels, not just a selected mix or subset. With the eleven outputs provided by MADDA111 you can easily send all your audio channels to all your audio areas.

By including just the essential features for a MADI DA - with its cost-effective non-reclocked outputs and simple LED and GPI signal monitoring - Crystal Vision ensures MADDA111 stays a truly low-cost solution to MADI distribution.

Choose your sampling rate

MADDA111 gives you flexibility. It supports 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.

The AES10-2008 specification allows 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%.

Signal monitoring

It’s always good to know you’ve got an input. MADDA111 includes useful signal monitoring, providing both LED and GPI output indication of signal presence, as well as on-board power supplies fault.

Save rack space

Crystal Vision frameMADDA111 fits 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.

The 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.

Protect your audio output

Using MADI allows you to have all your audio available everywhere – so if you lose your MADI you potentially lose all your audio.

With this in mind, the RM67 frame rear module includes relay bypass protection on power failure or board removal, giving that extra layer of security and preventing signal loss.

 

Specs

MECHANICAL

'Double decker' Crystal Vision module 266mm x 100mm (uses two frame slots)

Weight: 200g

Power consumption: 5.2 Watts

AUDIO INPUT

One MADI (AES10) input

Sampling rates supported: 32 kHz to 48 kHz +/- 12.5%, 56 channels; 32 kHz to 48 kHz nominal, 64 channels; 64 kHz to 96 kHz +/- 12.5%, 28 channels

MADI (AES10) cable equalisation up to 250m using Belden 1694A or equivalent

AUDIO OUTPUTS

Eleven non-reclocked MADI (AES10) outputs using RM41 + RM34 or RM67 + RM34 frame rear modules

The RM67 frame rear module provides relay bypass protection. An electromechanical relay switch needs power to hold the switch in one state and will revert to the other state (board bypass) on loss of power. It prevents signal loss by mechanically connecting the input of the MADDA111 to its fourth output on complete frame power failure or board removal

Output Amplitude: 600mV +- 10%

Output Rise/Fall Time: 1-3ns

Additive Jitter: 1ns p-p typ.

DELAY THROUGH BOARD

What outputs do I get?

Signal inputs and outputs are accessed by using an appropriate rear module.

The Indigo rear modules slot on to the back of the frame and typically feature BNC, D-Type, RJ45 and optical connectors. The single and double slot rear modules can be used with all three frame sizes, while the quad slot rear modules just fit the 2U frames.

There are two rear module combinations available for the MADDA111...
