Janus preamp hum and hiss

Postby Rune on Wed Jul 15, 2009 10:12 am

Hello.

I have a Janus rail preamp, that I bought from you a while back. i have the 5-pin powersupply also. Is the Pre-amp supposed to have hum and hiss, or is there something wrong? Its A 73 stagepiano, and the original preamp didnt manke any noise, but it also didnt need a powersupply.

Best
Rune.

Hi Rune,

There is never supposed to be a hum on a pre amp, it's obviously coming from the power supply, most likely from the 220V conversion. All of our power supplies and pre amps are checked completely before leaving. A pre amp will rarely cause hum, must be from the power supply. Original pre amp was passive with no electronics. Best, Chris
