B.1.8. HEADPHONES VOLUME CONTROL
On the front side of the ME-TUN there is totally to the right side the headphones connector.
This is a standard ¼” Jack as very widely used for headphones worldwide.
There are two push-buttons to the left of the headphones connector. These are serving for
the headphones volume control in a highly sophisticated microprocessor controlled manner:
•
after powering up the ME-TUN both push-buttons are illuminated. This is signalling
that the volume control is in its “normal” (default) position. This position is equal to
approximately 12dB below maximum volume.
•
shortly pressing onto one of the buttons is increasing rsp. decreasing the headphones
volume by 1dB. When the volume ends up to be BELOW the default value the lower
button (DOWN) is illuminated and when it’s ABOVE the default value the upper
button is illuminated.
•
pressing one of the buttons for more than approximately 1 second leads to a volume-
jump of 1dB and - after this - to a fine fading up rsp. down (until eventually the
maximum at 0dB or the minimum at -42dB is achieved)
•
pressing briefly onto both buttons simultaneaously is forcing the volume to jump to its
lowest possible value (approximately 42dB below maximum volume)
•
pressing onto both buttons simultaneously for more than approximately 1 second lets
the volume first jump to its minimum value (-42dB) and then up to its “normal” default
value (12dB below maximum)
