Power amplifiers with auto turn-on 'sense' feature.

[abdo123]

I'm looking for a power amplifier with little power (~20-30W at 8 ohm) with RCA inputs for a sensitive speaker (93 dB/W).

Other than decent objective performance, it has to turn on when signal is being received via the RCA inputs.

Feel free to suggest other ways of turning it on; However, none of my playback devices have trigger out.

Class D is also a plus, since I don't have a 'Hi-fi rack' than can have 15 kg amplifiers bolted to it.

NAD C268 - auto-sense via RCA - 80 watts, but who's counting?

With my current amp (45W) i never even reach half way through the volume knob. So i would rather not buy something that high.

Thank you for the suggestion though, i will keep it in mind!

Power output has nothing to do with voltage gain... The 80W amplifier may have less gain than the 45W. Check the specs.

I'm confused, my current amplifier is integrated (that I grew out of, and ended up buying better performing individual devices). So wouldn't the volume knob (the pre-amp section of the amplifier) be proportional to the power output?

XTZ A2-300 (495 Euro) has the auto sense, small size and class d you're looking for with plenty of power. Also has a gain adjustment on the input which helps to get more travel on your volume control if you need it.

The Monoprice 18513 will do the job for $113......

I use one in my home office, and the auto sensing feature works very well (possibly half a second delay in powering on)

The C268 has a gain control, so you can turn as far down as you like - with better noise as a result. You could limit it to 20W.

what's your budget? There are 20-30 wpc amplifiers out there with prices as much as 4 figures. Solid state or Tube? what's your preamp if you have one? if yes, does it have 12V trigger out?

I got one of these for zone 2 amplification...

You need a preamplifier with a 12V trigger through which your power amp can be connected so that when you turn on preamp your power amp will turn on automatically. It's always best to get preamplifier the same brand as your power amp so that you will not have compatibility problems.

This one senses signal on the rca inputs. Works with pre-outs from AVR or output from DAC.

I am sorry but I don't think I can help you any further. I absolutely know nothing about AVR setups.

Not asking for help. Was responding to the original poster. Plus you seem to think I'm mistaken. I plug my dac directly into the amp and it comes on when music starts playing. No 12v trigger required, but it also has one of those.

Oh dear...My apologies...LOL

Right. You must be a lot of fun at parties.

As a matter of fact I am, even though I have to say so myself

You could use a smart power strip....
