Connecting Pedals; Connecting A Switch Pedal; Connecting Dual Switch Pedals - Kurzweil SPS4-8 Musician's Manual

Getting Started

Connecting Pedals

Connecting Pedals
Plug your switch or continuous pedals into the corresponding jacks on the SPS4's rear panel.
We recommend using the Kurzweil pedals described in Pedals (Optional) on page 1-2, but you
can use almost any switch or continuous pedal that adheres to the following specifications
(as most pedals do):
The pedals are independently assignable within each zone of every setup. Here are the
default settings for the three pedals you can use with the SPS4:
NOTE: Be sure not to step on the switch pedals when powering up your Stage Piano!

Connecting a Switch Pedal

When plugged into the SW PEDAL jack on the rear-panel, a single switch pedal will, by
default, act like a sustain pedal. Of course this can be changed by programming, as described
in Setup Mode on page 7-1.
If you use a third-party (non-Kurzweil) switch pedal, make sure it's connected before you
turn on your SPS4. This ensures that the pedal will work properly (it might function in
reverse—off when it's down and on when it's up—if you turn on your SPS4 before plugging
in the pedal). Similarly, don't press any of your switch pedals while powering up, as the SPS4
verifies each pedal's orientation during power up—if you're pressing a pedal, you might
cause it to work in reverse.
See Switch Pedal Problems on page 12-5 if you are having trouble with your switch pedal.

Connecting Dual Switch Pedals

The jack will also accept a dual switch pedal having a single stereo plug. The plug should be
wired so that the left pedal connects to the ring contact and the right pedal to the tip contact.
It's also possible to use two single pedals with this jack: first buy a 1/4-inch stereo-to-dual-
mono Y adapter (this will have two mono 1/4-inch phone jacks and a stereo 1/4-inch plug);
then, plug the pedal you wish to use for sustain into the left jack and your sostenuto pedal
into the right jack. Note that the "left" pedal goes into the right jack and vice-versa.
