Getting Started
Connecting the Power Cable (Line Cord)
Connecting the Power Cable (Line Cord)
The SPS4 runs on 19 volts DC power and requires 3.4 amps to power the built-in amplifier.
Your dealer will provide the voltage adapter and power cord to match the AC power in your
area: 100, 120, 230, or 240 volts at 50–60 Hz. Plug the adapter into a wall outlet, and then
connect the adapter to the DC power jack.
Connecting to an External Audio System
Although your SPS4 contains a built-in high quality amplifier and speakers suitable for solo
playing in a small room, you may wish to use a more powerful external sound system for
large rooms and group playing. Needed are a pair of audio cables with 1/4" plugs on one
end and plugs compatible with your sound system on the other. If connecting to a mixer,
"balanced" (stereo) cables may transfer a stronger signal and lessen noise.
After you've turned down the level on your sound system, connect the SPS4's analog audio
outputs to your sound system using a pair of stereo or mono audio cables. Mono cables will
always work, but if you're going into balanced inputs, use stereo cables for a better signal-to-
noise ratio and a bit more volume: the SPS4's analog outputs are balanced.
You'll find two 1/4-inch balanced audio output jacks on the rear panel. For now, connect
one end of each audio cable to your mixing board or PA system inputs, and connect the
other end to the jacks marked LEFT and RIGHT on the rear panel of the SPS4. If you have
only one input available, use the SPS4's Left output to get the full signal in mono. Use the
front-mounted jack marked HEADPHONES to listen to the SPS4 on headphones. Note
that when headphones are plugged in, the built-in speakers are muted but sound still comes
through the LEFT and RIGHT audio jacks.
