So the HK525 "volume" goes from -80dB to +10dB. Why does it do this? Does the positive dB really mean something? Not just stop at 0dB?
When would the HK525 output the theoritical 70 watts per chanel? When it's at 0dB or +10dB?
The HK525 manual says you should calibrate with the volume set to -15dB. It also says that if you use an SPL meter you should calibrate for 75dB. So do you agree that -15dB on the know should give you is 75dB SPL and therefore 0dB on the knob would be 90dB SPL? That's certainly not reference (105dB), which confuses me.
Any thoughts are appreciated.
