VIDEO
The front panel of the DD1500m is very simple comprising just a single POWER ON/OFF
switch and indicator. The rear panel, however, is a different matter! From left to right...
DIGITAL INPUTS A AND B
There are two AES/EBU digital inputs on the DD1500m supplied as standard. These are
on XLR type connectors and will accept AES/EBU signals as well as SPDIF signals. These
inputs may be freely assigned to any track (or tracks) for recording. It is quite possible if
you are deriving your audio digitally from DAT or CD, that these inputs may be sufficient
for your system and one input may be patched to the digital outputs of the CD and the
other to the DAT, selection being made when you assign the input(s) to the track(s) for
recording.
It is possible to record through both digital inputs simultaneously provided the source
material is synchronous and at the same sample rate.
MIX A/MIX B DIGITAL OUTPUTS
These two AES/EBU digital audio outputs carry a stereo mix as set by the DD1500m’s
internal mixer. Level and pan may be set for tracks using the fader and pan control found
on the DL1500 and individual cue’s level and pan may also be set. In this way, you can
achieve a totally digital mix of material (albeit without EQ) within the DD1500. Furthermore,
MIX A and MIX B can have different mixes.
OPTION SLOTS
The two option slots found above the digital inputs and outputs can accept more digital
inputs using the DI04 and DO4 digital interface boards. In this way, up to 12 inputs and 12
track outputs may be added if you wish allowing you to integrate the DD1500 into a totally
digital studio where you may be using a digital mixing console.
ANALOGUE UNIT
This allows you to connect up to two DD1500a ADC/DAC units to add analogue inputs
and outputs to the system.
Up to two DD1500a units may be connected to give a total of 12 analogue inputs, 16
analogue track outputs and MIX A and MIX B analogue outputs. All inputs are balanced
+4dBm type.
