The optional Kurzweil CC-1 continuous control pedal will work best with the PC4, but
it is also possible to use third-party continuous control pedals designed for keyboards.
Compatible pedals should use a 10 kΩ linear-taper potentiometer, with a 1/4 inch tip-ring-
sleeve (stereo) plug with the wiper connected to the tip.
RIBBON Jack
Use the RIBBON jack to plug in the optional Kurzweil Ribbon Controller. By default the
ribbon controls pitch bend, but you can also program the ribbon controller to send other
MIDI messages. To use the ribbon controller, just press it, and slide your finger along the
ribbon to change the value of the message it’s sending.
You can configure the ribbon to have one control section that runs its entire length, or to
have three sections of equal length. It sends its highest values when you press it at the end
where the cable connects. When you configure it to have three sections, each section sends its
highest values at the end closest to the cable.
Caution : The modular jack is designed for connection to the Kurzweil Ribbon Controller
option only. Don’t plug any other modular plugs into the Ribbon jack.
AUDIO IN LINE/LEFT/RIGHT Jacks
Use the AUDIO IN jacks to mix external audio sources with the sounds of the PC4. This
is useful for playing along with backing tracks from a portable music player, computer, or
other electronic instrument. The LINE jack accepts a stereo 1/8” plug at line level, suitable
for input from MP3 players and computers. The LEFT and RIGHT jacks each accept a 1/4”
plug at line level, suitable for input from mixers and electronic instruments. Sources that are
not line level (typically guitars and microphones) should be amplified with a pre-amp, mixer,
audio interface or other device. Input volume and FX can be adjusted in Global Mode.
AUDIO OUT LEFT (MONO) and RIGHT A/B Jacks
Use the AUDIO OUT A/B jacks to connect to an amplifier or mixer. See Quick Start on
page 4 for details.
HEADPHONE Jack
Use the HEADPHONE jack located on the left rear panel of the instrument to listen to the
PC4 on stereo headphones. You will need a 1/8-inch-to-1/4-inch adapter in order to use
headphones that have a smaller mini plug connector.
When headphones are plugged in, audio is still transmitted from the AUDIO OUT jacks.
