8. Connecting headphones
You can connect commercial headphones to the 3.5mm socket (20) on the back of the device if e.g. you do
not want to disturb your neighbours at night. Playback over the built-in speaker is switched off automatical-
ly when the headphones are connected.
First reset the volume of the digital drum kit to zero. Put the headphones into the socket (20)
and then put them on. Now carefully turn up the volume.
With excessive volume there is a danger of hearing impairment!
Therefore set the volume so that it feels pleasant and is not too loud!
9. Connecting an external amplifier
An external amplifier (with line input level) can also be connected to the 3.5mm socket (20) in place of head-
phones.
Turn the volume on the digital drum kit to zero and switch it off.
Switch off the external amplifier.
Connect the external amplifier. Connect the socket (20) with a suitable cable connection
(3.5mm stereo plugs on two cinch plugs) e.g. with the AUX-IN or TAPE-IN on the amplifier. It
must be an input with LINE level.
Turn back the volume of the amplifier.
Switch on the amplifier and the digital drum kit afterwards.
Carefully turn the volume of the digital drum kit and amplifier somewhat higher; set the desired
volume.
