Proper orientation of plug
Place the power supply somewhere where it will stay dry and out of the way. We recommend
keeping it on the ßoor. Never cover the power supply with anything; it needs adequate
ventilation to prevent overheating.
Connect the plug at the other end of the power-supply cable into a standard power outlet. If you
plan to take your PC2 to a location that uses a different voltage level, youÕll need to get an
additional power supply thatÕs compatible with the local voltage.
Audio
The PC2 features balanced left and right analog audio outputs with
1
/
4
-inch jacks. For best
results, use balanced cables to connect to balanced, line-level inputs on your mixer or sound
system.
ItÕs important to use shielded, twisted-pair cables. The cables should each have
1
/
4
-inch stereo
(tip-ring-sleeve) plugs on one end to connect to the PC2. The other end of each cable should
have either
1
/
4
-inch stereo plugs or XLR plugs. Cables of this type provide balanced operation,
which greatly reduces many types of noise. Unbalanced cables or sound-system inputs wonÕt
give you quite the same audio quality.
For best performance, set the PC2Õs Master Volume slider to its maximum when adjusting mixer
or sound-system levels. Otherwise, if you adjust the PC2Õs level by increasing the level of your
sound system, youÕll increase the noise level.
If youÕre using a monaural sound system or running the PC2Õs audio into a single mixer
channel, we recommend conÞguring 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 4-26 for information about using mono audio output mode.
The PC2 has a headphone jack, which carries the same signal as the main outputs (thatÕs true
whether youÕre using stereo
or
mono output). The headphone jack accepts a standard
1
/
4
-inch
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, youÕll get better audio quality using the
headphone jack.
ThereÕs also an RCA digital audio jack, which you can use in addition to the analog outputs. See
page 2-6 for more information.
