Sound still coming out of speaker cab even at zero volume on PS-2A

Hi Fryette Team,

Apologies if this has been answered somewhere before already (I couldn’t find a solution to this specific issue). I’m using a PS-2A with my Amplified Nation Wonderland Overdrive V2, running into a 16-ohm cab with the impedance set correctly (16 ohms in and out). The speaker cables are connected properly, and the unit is not in bypass mode.

The issue I’m encountering is that, even with the Volume knob on the PS-2A turned fully counter-clockwise, I’m still getting a noticeable amount of signal through the cab. The Volume knob does affect the overall level and increases as expected when turned up, but it doesn’t bring the output all the way down to silence like I’ve experienced in the past with other PS-2 units.

The Line Out Level is set to 0, and there’s no gear in the loop. I’ve tested with my amp’s master volume lowered as well, but there’s still more signal than I’d expect at minimum PS-2A volume.

Is this normal behavior for the PS-2A, or could this indicate a fault with the volume attenuation circuit? I’m only using it as a volume attenuator in the room, essentially just as a “master volume” once I dial in the amp to it’s sweet spot (which is way too loud for my space on its own). I tested the amp with my other PS-2 unit, and it works correctly (silence from the cab with Volume at zero on the PS-2). It only seems to be occurring on the PS-2A.

Thanks in advance for your help!

Yes it is normal. Every one I have seen does it.

It used to cut the volume completely at zero, this just started happening recently. It’s not just a tiny bit of signal either - when it’s set to zero it’s about as loud as I would set it manually. Seems like something may be malfunctioning.

Some small amount of bleed is normal.

But you say it used to go completely to zero and now it doesn’t. That makes me suspect that something else is up because I’ve never seen one go to dead quiet with the volume on zero unless your amp is not very powerful in the first place.

The only way I would be able to confirm if the difference is now really significant is to examine the unit. If it’s enough of a problem that you think it warrants sending it here, you’re welcome to do that.
