Hi guys

I'm trying to find out the following, maybe someone can help me:

So I'm building a hifi, which consists of the following:

1. 600W Power Amplifier (2.1)
2. Receiver unit
3. Raspberry Pi Powered Music Player using Volumio

This is about the Power Amplifier, or maybe all.

I need to add a power switch to my units, how would one connect those power switches to the units?

Please let me know if something isn't correct cause I'm not sure if I'm asking the question correctly.

Thanks in Advance. :)

The simplest approach, if you want to control everything on a single switch, is to install a power-strip (heavy-duty) and switch everything that way.
Just be sure that your amp has a delay-relay of several seconds, at least.

If the amp does not have a delay-relay, then switch it separately. First, the sources. Count slowly to ten. Then the amp.

"Receiver unit"? Do you mean pre-amp + tuner, or a genuine receiver (tuner + pre-amp + amp in one box)? If a receiver, then it must have a pre-out with volume-control. A line-level output such as a Tape Out will leave you with no volume control on the amp.
