Question on Harman Kardon AVR 230 (1 Viewer)

[kvining]

Hi, new to the forum, hoping I can get a question answered. I have picked up a nice used HK AVR 230 6.1. On the back, I have a section of outputs called "pre amp" outputs, with one set of outputs for each surround channel. I am a little confused by the name - does it mean this is a signal that can be sent to a seperate pre-amp, or is it a pre-amplified signal that can be sent direct to a power amplifier, with the volume controlled by the HK ?
 

Thanks!

It's a low-level (not amplified) signal sent to an amplifier. Much like any audio signal between, say, a cd player and a receiver using audio cables. When connected to an amplifier the H/K will control the volume.
