Cracking sound


#1

Hi. I’m having big problems with my Sprout amp. Before I even start a record, there is a high and annoying buzzing sound as soon as I choose vinyl. And when the record starts, the sound is cracking and awful. Makes Tom Petty’s “Refugee” sound like Neil Young’s “Hey Hey, My My (Into the Black)”.

I’ve tried both a simple Denon vinyl player and a more fancy Pro-Ject player, both sound awful through my Sprout - and normal on my old amp.

Any suggestions? Is the amp damaged or am I doing something wrong?

Tell us what you’re setup is like. That’ll help get us started. I’ve asked the customer service guys to jump in here and see if they can help. We’ll get you sorted out.

Do you happen to know if both the “players” have built in phono preamps? If they do they will not work with the Phono input, you would need to use a line level input. The Analog input would be the one to try. If that doesn’t work you should probably contact PS Audio service for their advice. Nice folks and very helpful.

Hello Tobben,

Some turn tables amplify the output to the single ended terminals. If you would, please try the analog input of the Spout. If the issue is not resolved then please reach out to us at service@psaudio.com

Thanks,

Hi guys! Thanks for your quick responses. I tried the analog input, and guess what: It worked! So everything is good. Thanks again! :slight_smile:

By the way, here’s my setup:

My preferred vinyl player is Pro-Ject RPM 1.3 Genie. This one:

It comes with a Phono Box:

I’m using the phono box now. Is this necessary with the Sprout?

My alternative setup is a Denon DP-29F player. This one:

No phono box with that one.

Loudspeakers are Dali Zensor Pico:

Appreciate your thoughts on this, guys. :slight_smile:

If you use the Phono Box you need to connect it to the Sprout’s analog-in stereo mini-jack rather than the phono RCA connectors. The Sprout has it’s own Moving Magnet phono stage and you do not want to use two phono stages. I suggest you try it both ways and pick the one that sounds best to you. If you use a low output moving coil cartridge you would need to use the Phono Box.

Thank you, guys. I need the phono box still, and play through Analog. All good!
