Corrections/Additions
There are two items that we published as supplements to Revision A of the PC2 Musician's
Guide. The first addresses audio quality. The second item is a table that lists the PC2's MIDI
Controller assignments. This table was incorrect in some copies of Revision A.
For Best Audio Results
1
The PC2 features balanced left and right analog audio outputs with / -inch jacks. You'll get
4
your best signal-to-noise ratio using balanced cables to connect to balanced, line-level inputs on
your mixer or sound system.

You should use shielded, twisted-pair cables. The cables should each have / -inch stereo
4
(tip-ring-sleeve) plugs on one end to connect to the PC2 (see the diagram). The other end of each
1
cable should have either / -inch stereo plugs or XLR plugs. Cables of this type provide
4
balanced operation, which greatly reduces many types of noise. Unbalanced cables and/or
unbalanced sound-system inputs will give you slightly lower audio quality.

For the highest audio quality when using a sound system, set the PC2's Master Volume slider to
its maximum before adjusting sound-system levels. This gives you the cleanest possible
signal—better than setting the PC2's Master Volume slider to less than its maximum and
compensating by increasing the level of your sound system.
If you're using a monaural sound system or running the PC2's audio into a single mixer
channel, we recommend configuring the PC2 for mono output, in which case the PC2 sends the
same one-channel signal to the left and right sides of both the analog and digital outputs. See
page 26 of the Musician's Guide for information about using mono audio output mode.
The PC2 has a headphone jack, which carries the same signal as the main outputs (that's true
1
whether you're using stereo or mono output). The headphone jack accepts a standard / -inch
4
stereo plug, and is compatible with nearly all types of headphones. Plugging into the
headphones jack does not mute the other audio outputs.
You can also use the headphone jack as an unbalanced stereo line-level output. Just connect a
stereo cable from the headphone jack to a stereo input on your mixer or sound system. If you
have only unbalanced inputs to your sound system, you'll get better audio quality using the
headphone jack.
There's also an RCA digital audio jack, which you can use in addition to the analog outputs. See
page 6 of the Musician's Guide for more information.
