Hi there,

I don't normally use bypass mode. However, I recently inherited a decent turntable, and I wanted to use bypass mode last night.

I turned off my sub at the source, so there's none of that to get in the way.

So I'm listening to some Steely Dan on vinyl, and kick it into bypass mode; there was effectively no change. Still in bypass mode, I go into the OSD and set main speakers to "large". Now my bass is present in my mains.

This morning, I did a little test. This was using my PC with an optical connection. Send a 70 Hz tone to the 990. Enter bypass mode. Set crossover point at 100 Hz. Switch between large and small in the OSD. Bass comes and goes in the mains. No sub attached.

So what's up? The "990 Digital Bass Management Matrix" indicates that bypass mode will set the mains to "Full Range" regardless of all other settings, and in all cases. I note that the "990 Digital Bass Management Matrix" has an overall header of "Analog Input Signals". As noted above, I've tried this with both a PC as input to the 990 (digital), as well as a turntable (analog).

Anyone else see this?
