The DADA208D doubles as both a dual distribution amplifier and an audio delay line.

It has reclocked outputs and includes a selectable delay of up to one second at 48kHz making it ideal for matching delays in video processing equipment unable to pass embedded audio, such as certain ARCs and DVEs.

With an independent delay adjust on each channel, the delay is selectable by a combination of DIP and rotary switches in one video field steps from 0-51 fields (625 line) or 0-61 fields (525 line).

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.

The DADA208D has cable equalisation and both GPI and board edge indication of input present.

Offering up to 24 channels in 2U, the space-saving 100mm x 266mm module is controlled manually from board edge.

The DADA208D 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.

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