    Computer noise through system and RME ADI-2 Pro Questions

    Two things changed last week. 1) Got the RME ADI-2 Pro in the mail 2) Got a 3mm to RCAs lead to facilitate playing the iPad through the system. So I hooked up an RME ADI-Pro and it would not record in any quality way. I spent a day copying the SSD in a MacBook Pro (MBP) and upgrading the OS. I...

    Speaker cables

    Why is it that when people on another forum see an avatar of a speaker cable using lamp shade, they discredit the person posting? I probably would have used something better, but I have been waiting ~5 months for the mogami to get in-stock and ship. (and the speaker sound better with a lamp...

    Penultimate thread on bi-amping, DSP, and active XO (2 way speaker)

    Well the oddest of things, is happening. Which is that I am pretty solidly headed to new set of speakers. Are there any good resources on active XOs and DSPs? I have an APL DSP, and a couple of Hypex FA502s. I can use pretty much any DSP that is available, but the tweeter likely wants a low...

    Power-Cord/ Power-Conditioner testing

    How would someone gop about testing power cords or power conditioners? Maybe some broadband noise and 60 Hz on the plug end, and then look at the spectrum coming out of the amp end? I am always sceptical of the claims, but have no reason to doubt that a choke wouldn’t alter what iOS presented...

    This is probably the wrong sub forum… but what do people use for harmonics and resonance measurements? I found a Slam-Stick accelerometer, ($1500-$1800) and a bunch of lower frequency Arduino-based solutions, as well as expensive B&K equipment. I think that I need something that goes to 1000Hz...
