Looking for some helpful info.

Hello to all. I recently bought an HSU powered sub to connect to my VTL IT-85 integrated amp. The IT-85 has a pair of pre-out L and R jacks. When I hooked up the low level inputs of the sub to the pre-out of the IT-85 I get no sound. I use an Audioengine B-1 Bluetooth Dac which is connected to an audio input on the IT-85. I tried an RCA splitter from the AE B-1 output and connected to the HSU sub and it works fine. The only problem is the sub is at a fixed level when using the IT-85 volume control. I want to have the pre-out connection working so I have a variable volume level. Any ideas why the pre-out isn't allowing the signal to go from the IT-85 to the sub?

Is there a tape monitor button or similar on the pre?

As I said it is an integrated amp. pix of front and back.

On the back, I see:

1. Preamp out

2. Tape out (monitor out?)
Try this one.
You might need a passive volume control between that output and the subwoofer input.

Pre-out will not work if the Processor switch is ON (up position).
