Can I Increase/Decrease The Input Signal To A Receiver?
I'll layout a simple scenario to get us started and if more detail is required, just ask.
I have 2 devices attached to a receiver, an Echo Dot that is attached the receiver's CDR input and a cable box/DVR that is attached to the receiver's DVR input.
The issue is that the strengths of the input signals is so different that the receiver's volume has to be so low for normal listening of the cable box/TV that the Dot's volume has to be set to 10 (max) to be barely heard. That leaves no room to raise the Dot's volume by voice. I'd like to set the Dot to level 5 or 6 and set the volume on the receiver to a level that maintains the same output volume when switching between inputs. That way the Dot can still have some volume control of it's own
Right now, if the Dot is set to 5 and the receiver is set to a volume that allows for easy listening, switching the receiver to the cable box input without first lowering the receiver volume significantly is going to blow up my speakers.
The volume level of the cable box RCA jack outputs is fixed, so I cannot adjust that. If I could attenuate that signal, or raise the Dot's signal, before they hit the receiver inputs, I might be able to achieve better balance. Is there a relatively inexpensive way to do that?
