I'll give Frank a call.
For anyone familiar with the Nano 300...what is the switch that has a note on it? It's on each channel. Is it some sort of EQ?
I can't find much on the HK website.
9 Contour
This rotary knob voices the audio signal;
that is, it adjusts the tone.
It boosts low and high frequencies while
cutting midrange frequencies.
• Far left position = no change in tone
• Far right position = maximum effect
