Hi there,

I want to add an external FX-processor to my 2500, utilising the SPDIF in/out connections for resampling, so that it's
possible to stay in the digital domain, once sampled with the 2500's AD-converter.

I wonder how the specifications in terms of bits and hertz are important to choose the
right FX processor. The 2500 is known to be 44,1kHz and 16 bits. I was thinking of the TC Fireworx (44,1 kHz/ 20 bit)
or the Lexicon MX400 (44,1 kHz, 24 bit).

Has anybody experienced issues as far as the bit-width is concerned.

Thanks for any hints!

The spdif will work with the Fireworx for sure, but be aware that you can't use the 2500 spdif outputs like the analog outputs. They basically output the same audio as the main stereo output. Not amazingly flexible, but then you could always hook up a pair of analog outputs to the Fireworx aswell.

Hi rozzer,

you're right, the routing possibilities are rather marginal. The external processor could be implemented like this:


MPC-SPDIF-out
|
V
|
FX-Processor--------analog out---------> Recorder
|
V
|
MPC-SPDIF-in

In the sense, the processor is mostly bypassed, if not resampling and no global effect is desired.

PS: I think you're the guy who put this cool video with that small dragon on youtube (grrrrrhhhhh....) :D
