Details

Distribute AES audio anywhere

The DADA208 is a dual digital audio distribution amplifier with reclocked outputs, ideal for use in all broadcast areas where AES signals need to be distributed.

It should be used for high protection requirements and can correct unstable AES inputs. An active cable equaliser makes it the first choice for long cable lengths.

Use it as a dual channel or single channel device

It has two stereo feeds in and up to four outputs of each channel, or can alternatively be configured to have one input and up to eight outputs.

When used as a dual channel device, it can fit up to 24 channels in 2U.

Eight rear modules for flexible outputs

The DADA208 can be used with eight different frame rear modules to obtain just the output configuration you need.

For 75 ohm audio...

  • The RM01 gives two outputs of each channel
  • The RM02 gives three outputs of the first channel and four of the second
  • The RM16 gives four outputs of each channel with an AES loop-through of the first.

For 110 ohm audio...

  • The RM03 gives four outputs of each channel
  • The 'easywire' RM35 gives four outputs of each channel, with its audio connections on a 64-way DIN 41612 connector which stretches the full width of the rear module and therefore gives more room to solder the wires on to the individual pins.

For impedance conversion...

  • The RM12 gives two 75 ohm inputs and four 110 ohm outputs of each channel
  • The RM13 gives two 110 ohm inputs and three 75 ohm outputs of each channel
  • The RM21 gives two 110 ohm inputs and two 75 ohm outputs of each channel.

Save rack space

Crystal Vision frameThe 100mm x 266mm module fits in Crystal Vision's standard rack frames alongside any other products, allowing 12 boards in 2U, six in 1U or two in a desk top box.

The DADA208 offers manual control and has both GPI and board edge indication of input present.

Crystal Vision offers the choice of three digital audio distribution amplifiers, with options including reclocked and non-reclocked outputs, BNC and D-Type connections, impedance conversion and the ability to incorporate delays.

What outputs do I get?

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

The rear modules slot on to the back of the frame and typically feature BNC, D-Type, 'easywire' DIN 41612, 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 eight rear modules available for the DADA208...
