Title: I-Tech DSP question
Post by: J. Stanton Steward on July 28, 2010, 11:17:25 PM
I'm setting up a delay stack which will be 250 feet from the main PA.  The delay stack is comprised of 2 SRX728 and 2 SRX725 powered by 2 IT6000's.  I'm running the 725's passive/full range.  I'm using the itechs' dsp for x-over, peq, limiter and input delays.  I'm daisy chaining the I-techs together so that I will only be feeding the delay stack with one input.  

I've set a 250 foot input delay on the I-tech which recieves the initial feed input.  Since I'm daisy chaining the i-techs together, does that delay transfer to the second amp or does the signal pass completely unaffected so that I would need to set a 250 foot delay on the second amp as well?

Everything I've read tells me the signal is passively passed through with no dsp on it, but I just wanted to make sure I'm not completely wrong or missing anything.

Thanks in advance.

The text in bold is correct.  No processed signal appears at the channel loop-through outputs.

Have fun, good luck.
