Hints on using the DSP Upgrade’s additional 32/24 channels
When the Vi Series is upgraded with the DSP card addition, there are two ways to use the additional
channels:
1. Making more use of the existing I/O
The Vi6 already has 64 mic ins from the stagebox, plus 16 line inputs, 3 mic inputs, 16 AES/EBU inputs
and up to 64 MADI inputs in the Local Rack, plus the returns from the 8 built-in stereo Lexicon FX units.
This is a total of 179 sources!
This means that there are already plenty of spare physical inputs that can be used to access the
additional 32 mixing channels.
Just being able to connect the FX return channels without eating into the Stagebox inputs will be a major
benet.
With this in mind, the new Default Shows provided with the V3.0 and later software have been
programmed with the sources for channels 65-80 set to the Local Rack Line inputs.
The last 16 channels 81-96 have been left free to use for FX returns since there are different preferences
on the vertical or horizontal pairing of these.
2. Add another Stagebox
Alternatively if you require more than 64 inputs from the stage, a second Stagebox can added to the desk,
either by connecting it to the existing second MADI card, or adding a third MADI card. (In this case you
need to remove the AES/EBU card or 2 line in or line out cards to make room for the MADI card).
As mentioned previously, you may need to obtain additional breakout panels for use with a second
Stagebox.
When adding additional MADI cards and Stageboxes, keep in mind that there is a limit to the maximum
number of I/O channels that the DSP core can accept – this is 192 inputs and 192 outputs. The total of
all the input cards tted in the local rack must not exceed these numbers. It is possible to add a MADI
card and restrict the number of channels it uses, from 64 down to say 32, using internal switches.
Refer to your Soundcraft distributor for further advice on special I/O congurations.
