# Separate Audio Outputs with External Hardware

On the iPad, you can connect external USB audio hardware with multiple separate audio outputs.

If you want to specifically route the channels (left/right) of the 5 audio players included in SongBook+ to certain audio outputs of the external hardware, you can do this in the MediaPlayer settings of SongBook.

This can be used, for example, to play a synchronous click track for the drummer that only he hears.

**Tip for Acoustic Metronome:**

For the acoustic metronome of SongBook+, unfortunately, a specific audio output cannot be assigned. The metronome will always be output via the first two channels of the external hardware.\
\
However, if you do not assign these first two channels to any of the audio players, you can still output the metronome separately from the audio players.
