Otherwise (when using the built-in speaker), all three channels are mixed at the same intensity. This signal appears to be also sent to the Tape output line also, so a connected Data Recorder could be used to record CPC music also.

== BASIC Sound Test ==
You can test the channels with simple SOUND commands in BASIC:
SOUND 1,440,1000,15 should produce a sound in the right speaker. (channel A)
SOUND 2,440,1000,15 should produce a sound in both speakers. (channel B)
SOUND 4,440,1000,15 should produce a sound in the left speaker. (channel C)
