No sub control (1 Viewer)

[ccbc]

I have Cambridge sw t300 and a denon avr1910 I’m using the sub output from receiver but when I go to either increase, decrease or go to no sub I get no change in sub output level. The subs are working and I can use the controls that are on the speaker for sub level but I just can’t get any response +/- when trying to control from receiver. If I use the audessey mic to process when it gets to the sub I get some output but it sounds like possible only coming from one speaker and the output is minimal and certainly not at any sub frequencies. It almost sounds like it coming from one of the mids. I should investigate that further now that I think about it. Thoughts?

Casey,

How is your sub connected to your Denon? Do you have an RCA cable from the Subwoofer output, or is it cabled to the speaker lines?

It’s rca from passive sub out on receiver to powered subs

Something is definitely wrong. It sounds like things are connected or configured wrong. You'll have to provide more info on how those speakers are connected. I looked them up and they are essentially two way speakers with a built-in active subwoofer.

They have duel binding posts. They can be hooked up full range with jumpers or high and low separately. In the manual it shows connecting speakers full range one set of speaker wires to connections and using a set of jumpers to other binding post and with an rca from sub out to sub in. Another method of connection is showing jumpers removed and separate speaker wires going to high frequency posts and another set going to low freq posts and does not mention or show and rca connection to sub in. Nor does it show how those separate speaker wires are coming from receiver. My denon 1910 is supposed to be bi amiable. I did try connecting two speaker wires from receiver as instructed from denon manual one set from channel b right channel to high freq input and one from back surround right to low freq input and with rca to sub in from receiver sub out. All of this duplicated for left channel. The results were the receiver shutting down and going into protection at med/high level output. I figured I had basically paralleled the speaker and dropped the ohm load to receiver. I reverted back to one channel going to full range input with use of jumpers and rca to sub in and that stopped the protection shut down and put me back to square one.

Can you share a picture of the speakers and the binding posts? That might help us
