Adjustment of maximum gain
You can easily adjust the maximum gain of the Black Cube Linear to use any
available headphone with best results independent from effectivity or impedance.
The gain setting has direct effect on the active gain of the input stage which is
placed after the volume potentiometer. It is recommended that you choose a
setting which, at the maximum potentiometer position (turned clockwise), results in
a volume level that is slightly higher than your normal listening habit so that you
have a bit of reserve with lower level signals. You also make sure that
extraordinary high levels can be avoided much easier.
Gain with volume
turned to maximum:
Switch 1 Switch 2
0dB Off Off
10dB On Off
18dB Off On
20dB On On
The gain setting is done for each channel separately. Please make sure that both
channels show the same setting. Otherwise you will hear an abnormally twisted
stereo panarama.
Warning: Do not change the gain setting while listening to avoid suden
peaks that might damage your loudspeakers or even your hearing!
