Harrison Labs 12 dB RCA Line Level Audio Attenuator Pair
I was interested in the Harrison Labs 12dB Line Level Attenuator pair. I wanted to connect our Yamaha PSR-433 keyboard's headphone out to the stereo RCA of the stereo system. The headphone out comes out too strong. Will attenuator work?
You may have to use an adapter to convert the typical 1/4" to RCA type but it will reduce the level by about 12db. The other option would be to use a headphone amplifier to control the output.

Basically, do these reduce the outputs volume level so that it takes less power, or are they so you can turn the volume up louder? Can someone please explain to me the purpose of these?
These reduce signal levels into an amplifier. If the signal is too high and causes the input to clip, these will reduce that level and lessen the clipping problem.

This is recommended by Tweek Geek for the M2Tech Hiface USB to SPDIF converter
Where would I install these attenuators? My current set-up is PC's USB to HiFace converter to DAC to Receiver.
Tweek Geek is recommending that one of these goes between the HiFace converter and the DAC. These are directional so they should be used at the DAC input, assuming that you aren't using any gender changers on the RCA cable. Using it in the opposite direction will give you a lower attenuation level. The actual attenuation level that you achieve will depend on the input impedance of your DAC. Some experimentation may be necessary including no attenuators or both attenuators.
