ATTENTION:

Connect the sleeve to ground ( ). Connecting the sleeve to a negative (-)
terminal will damage the audio output circuits.

The length of the exposed (stripped) portion of the copper wires is important.
The ideal length is 3/16 inches (5 mm). Longer bare wires can short together.
Shorter bare wires are not as secure in the direct insertion connectors and
could be pulled out.
