Re: Peavey USB-P DAC

I can report that everything is working really well. Audio from the Peavey unit is very clean and latency is not a problem. I think this is a pretty great solution for a live performance software synth.

Re: Peavey USB-P DAC

Update: I used a ADUM3160 from amazon on the USB port and can report that it cleaned up the noise. Everything seems to be working. So far, with a midi to USB device and headphone jack audio, latency hasn't been an issue. I am very hopeful that the USB-P doesn't introduce painful amounts of latency. ...

Re: Peavey USB-P DAC

I use three of these for our podcast. One with Pulseaudio and the other two with Jack. Never had an issue with them. The output is on the low side. Nothing a preamp can't sort. If you are looking for a cheap isolator do a search on Amazon for ADUM3160. It is surprising to me that this is about the ...

Re: Peavey USB-P DAC

Just noticed if I unplug the power supply from the laptop and run on battery all of the noise goes away and I have good clean audio. I Will research further. That speaks volumes, ha ha. Good 'ol interference from a wall outlet (50 Hz; or 60 Hz if you're an American). Anyway, I'm glad you've got it ...

Re: Peavey USB-P DAC

Thanks all for help and suggestions. I have audio at this point. I have yet to confirm how it sounds as I am just confirming audio with a scope. It is definitely noisy due to noisy laptop USB ports I suspect. I am going to try some USB isolators to see if that can cure my problem. Open to suggestion...

Re: Peavey USB-P DAC

This appears to be a line level audio DAC device has USB connection from PC, 2*XLR outputs & a mono/stereo switch no hardware controls like some interfaces so level settings should be in alsamixer 'this unit complies with part 15 of the FCC rules' = class-compliant if it is visible in ALSA, sug...

Try setting it as the jack output device in the qjackctl settings. Does that work?



I think that worked. Audio is really noisy though.

Re: Peavey USB-P DAC

What software are you using? You are talking about "a live software synth setup", what exactly do you mean? You say "It is selectable". In what application? Problem is: does your software synth (a VST???) want to use Jack audio or ALSA? If you select your audio device in Qjackct...

Peavey USB-P DAC

I will be using AVLinux for a live software synth setup. I am trying to configure a Peavey USB-P USB DAC for output audio. Once connected up, I see it in alsamixer specified as USB Audio DAC, "lsusb" shows it as an Texas Instruments device, but I cannot get audio to play out through the DA...

editing midi in a softsynth

I have an old synth that I am using as a midi controller for AVLinux. While I like the feel of the keys, this synth does not provide a transpose feature. I know that there are some midi applications that can do the transposing, but I got thinking. If I wanted to change the midi keymapping in the sof...
