I'm measuring current and proposed units at the moment and I'll post some results when I'm confident that they're correct. -----Original Message----- From: Kim Flint [mailto:kflint@loopers-delight.com] Sent: 29 July 2002 19:56 To: Loopers-Delight@loopers-delight.com Subject: Re: edp + At 08:37 AM 7/29/2002, Mark Sottilaro wrote: >I will experiment with that tonight.

That can also have a low-pass effect. You may need to turn the input volume knob down a bit if that is the problem. >More importantly than range, how flat is the overall response? I know >most gear can be pretty flat these days. I don't remember the exact specs, but the digital path has a pretty typical flat response that all digital gear has. I believe the passband ripple is 0/-.2dB. The low-end rolloff point is well below 20hz. Between there and 19khz it would be flat within 0/-3db. But if you pull in a bit from the ends, it would be flat within 0/-.2dB (probably from 20Hz - 16Khz it would be flat within 0/-.2dB, but that's a guess because it has been a long time since I measured it.) like Bret said, if you have the gains set up right, you shouldn't hear any frequency problems. kim >On Monday, July 29, 2002, at 02:43 AM, Kim Flint wrote: > >>At 12:28 AM 7/29/2002, Mark Sottilaro wrote: >> >>>On Sunday, July 28, 2002, at 10:00 PM, Bret wrote: >>>>Specifically what aspect of the fidelity of the EDP is inferior to the >>>>repeater, for example signal to noise, frequency response, harmonic >>>>distortion, intermodulation distorion, hum, etc? >>> >>>seems to be a frequency response issue.
