i have a Sony TV KD55A1 and a Marantz Amp PM5004 and I want to be able to adjust the sound of the tv and amp together on the tv remote .Please help , thank you .
The simplest way yo do this is to keep the volume at the maximum acceptable volume for you and use the TV remote to control the volume. Or you can use Control for HDMI if the AMP features HDMI ARC.
