Unused channels on a multi channel amp

Porziob, He asks two ?s; unconnected outputs And capping inputs. Zero plus 1.

Tripper if there`s no input, why does the channel need a load. It`s a little bit like wondering what a dead person will have for dinner.

I tried to explain how signals could enter the unused channel(s) through extraneous and / or internally generated sources. I also tried to explain that most amps do generate "leakage" from their output stage on their own, albeit very small quantities most of the time. This is why i suggested resistively shunting both the inputs and the outputs as it completely isolates and protects the unused channel(s).

As a side note, using a resistive shunt on the input will not have any potential side effects compared to simply shorting the unused inputs. Using this method of resistively shunting unused inputs on a preamp can also be used to varying levels of success. In some cases, directly shunting or "shorting" the unused inputs on a preamp and / or power amp can result in sonic degradation. This has to do with poor isolation of each input i.e. higher than desirable levels of cross-talk, etc... Sean
