SEEBURG acoustic line SP2 Owner’s Manual Page 1
1 Introduction
Your new acoustic line SP2 is a very flexible device. Due to its wide range of adjustable
parameters it can also conveniently be used as an add-on for existing PA systems.
Read this owner’s manual carefully before putting your SP2 into operation, please!
The SP2 system controller becomes the central device of your sound reinforcement system as
soon as the signal leaves the mixing console (see fig. 1). This one piece of audio gear incorporates
a 2-way frequency dividing network, a dynamics controller and a four band EQ (optional) - all in
stereo and fully configurable - as well as a connection panel and still takes up only one rack space.

If you bought the SP2 together with or as an upgrade for an acoustic line PA system it is already
set up for optimum performance with this specific system. For use with all other brand names there
is a modifiable standard configuration which is described in appendix 4.3.
In order to change the SP2’s parameters it is necessary to open the device and exchange one or
more SIP resistor arrays and/or change some jumper positions. If you are not sure how to perform
these tasks properly, please talk to your SEEBURG acoustic line dealer first.
