The DD1500a contains the Analogue to Digital Converters (ADCs - inputs) and the Digital
to Analogue Converters (DACs - outputs) for the system. The system can accommodate
up to twelve inputs, sixteen track outputs and two stereo mix outputs A and B. These are
housed in the DD1500a and the DD1500m may have up to two DD1500a units attached.
The DD1500a comes with four inputs and four outputs as standard and you can add
inputs and outputs as you like according to your requirements, enabling you to build a
system that suits both your needs and your budget. For example, if you are using a
simple MO based 8-track system, you may choose to have just one DD1500a with two
DA4 boards installed giving you four analogue inputs, eight analogue track outs and
stereo mix outputs as well.
In a more complex setup, you may like to add another DD1500a for more inputs and
outputs.
There are some things to note about the DD1500a.
UNIT 1, the first DD1500a in the system comes supplied as standard with four ins and four
outs. The four inputs can be freely assigned to any track you like using the DL1500's input
matrix routing. In many cases, this may be sufficient regardless of the type of disk you
have and the number of tracks you are using. The 'hardwired' outputs on UNIT 1 are
always set to output MIX A and MIX B. Should you wish to have eight track outputs, you
must install two DA4 boards - you cannot use the 'hardwired' outputs supplied as standard
as individual track outputs on UNIT 1 as these are always outputting MIX A and MIX B.
If you have a second DD1500a, the 'hardwired' outputs are tracks 9-12 and fitting two
more DA4 boards would give you the remainder of the track outputs. Recommended
configurations are shown below and a diagram of a fully expanded pair of DD1500a units
is shown on the next page. If you are in any doubt about output configurations, please
contact your dealer.
