Connecting Audio Cables
Analog
With the level on your sound system turned down, connect the PC3A’s analog audio outputs
using a pair of stereo or mono audio cables. Mono cables will always work. If you are going into
balanced inputs, stereo cables will give a better signal-to-noise ratio and a bit more volume. The
PC3A’s analog outputs are balanced, and generate a “hotter” signal than some previous
Kurzweil instruments.
Four 1/4-inch balanced audio output jacks are on the rear panel. To begin, connect one end of
each audio cable to your mixing board or PA system inputs, and connect the other end to the
jacks marked Main Left and Right on the rear panel of the PC3A. If you have only one input
available, use the PC3A’s Main Left output to get the full signal in mono.
Using Master Mode you can set the Aux outputs to duplicate the Main Outs, which is useful for
monitoring and other operations. They are always in stereo, as is the headphone output.
Digital
For digital audio output from the PC3A, connect a 75-Ohm coaxial cable from the PC3A’s RCA
Digital Out jack to the AES or S/PDIF input of the receiving device. You may need an RCA-to-
XLR adapter to connect with the receiving device. If the receiving device receives only optical
signals, you’ll need a converter as well. The PC3A’s Master Page (press the Master mode button)
lets you select a range of useful sample rates for the digital output.
The RCA jack labeled “Sync In” allows you to synchronize the PC3A’s S/PDIF Digital Audio
output sample rate to an external S/PDIF source. Although no audio signal is received by the
“Sync In” jack, its clock is received and may be used to set the output sample rate. For details, see
the Master Mode OUTPUT page parameter. NOTE: Sync In is NOT a “Word Clock” input. Only a
valid S/PDIF signal is recognized.
Connecting MIDI
The simplest MIDI conguration uses a single 5-pin MIDI cable, either from the MIDI Out port of
your PC3A to the MIDI In port of another instrument, or from the MIDI Out port of another MIDI
controller to the MIDI In port of the PC3A.
