I am using the Pm8005 in home theater bypass mode, and unfortunately to switch it in and out of this mode you need to hold down the button on the front of the unit for three seconds. which is a minor inconvenience, but an inconvenience none the less.
The main problem though is that the remote controls For both my receiver and the pm8005 control both units. So it is impossible to control the volume of The PM 8005 without controlling the volume of the receiver as well. Changing inputs on the receiver remote also results in input changes on the PM8005
