Headphones.
Instead of using an amplifier system, you can use headphones as an alternative. To be exact
you could even use two sets at a time. But we wouldn't recommend wearing two sets at a time
- as that wouldn't do you much good.
The outputs are equipped with a small (200mWatt at 8 Ohm) headphone amplifier which can
be switched on at its own jumper (JP1 = Out 1, JP2 = Out 2) located on the board. Carefully,
move the small plastic switch from position A to position B.
51
Position A - headphone amplifier turned off ... (line operation)
51
Position B - ... and activated. (headphone operation)
If you switch on the headphone amplifier and then use a HiFi amplifier or active speakers, you
don't need to worry that you will "crash" anything. The only thing that will happen is that the
background noise will be noticeably louder in this situation.
Safety Tip.
Please remember to switch off all (analog) devices before connecting
them. This is to avoid the danger of electrical shock - even a weak one
- it also protects your speaker membranes and your hearing from
sudden signal spikes. For digital devices, the volume of your playback
system should at least be turned to low.
