now to USE ms cps-1
The GFS-l is designed to switch from among three independent speaker systems.
Each system or pair may be rated at either 4 or 8 ohms impedance and each channel
may be driven at up to 200 watts(protection out). _ , ,
To wage- a speaker system just depress the button that corresponds to that ' - a --
.pair of speakers. When using 2 or 3 pair -of 4 ohm speakers, or a combination of I
(sand 8 ohm pairs, the 'PROTECTION' is seen by the amplifier. This uniQue protection3-3i7-5 ?
system is'designed to protect your snip from the very low load impedances that are the .-
consequence of wiring multiple pairs of speakers' to one amplifier or receiver. ' "
. When switching betVeen- 3 pair of 8 ohm speakers, the 'PROTECTION" button shguld-
only be depressed when using all three systems at one time. Remember that the
o

' It is not recommended for use at extremely high listening levels because distorted .
peaks in the musical program may damage the GFS-l components; by causing excessive 4
