Connecting the system
Make sure that all components are
turned off before making connections.
Refer to Figure 2 for an illustration.
1. Connect your preamp's outputs to the
RS I's electronic crossover's inputs.
2. Connect the electronic crossover's
high pass outputs to the inputs of
a stereo power amp (or two mono amps)
that will be used to drive the mid-
tweeter sections.
3. Connect the mid-high powér amp's
outputs to the RS I's mid~tweeter
sections, observing polarity (+ to +,
~ to -) and left/right channel
identification.
4. Connect the electronic crossover's
low pass outputs to the inputs of
another stereo power amp {or two
additional mono power amps) which
will be used to drive the woofer
columns.
5. Connect the low frequency power amp's
outputs to the electric crossover's
amp inputs* (not to the woofer columns).
Observe polarity and left/right
channel identification.
6. Connect the electronic crossover's
speaker outputs to the RS I's woofer
columns. Observe polarity and left/
'xight
channel identification.

RS 1: SYSTEM, rear view
*These leads are not to exceed
6' in length
WARNING: Improper connections of the
low frequency circuit and/or incorrect
setting of the BASS AMP switch will cause
full power oscillation and possible
damage to your system, Steps 5 and 6
of the preceding instructions must be
followed exactly. In addition, the BASS
AMP switch on the electronic crossover
must be set in the proper position to
accomodate your low frequency power
amplifier.
Consult the manufacturer of the amp-
lifier to determine if it is INVERTING
or NON-INVERTING (explained in the
following section). (If you are using
two mono power amps, they must be
identical in this respect or the system
will not operate properly, and subsequent
damage will occur which is NOT covered
in your warranty.) Set the BASS AMP
switch (shown in the section covering
the electronic crossover unit, item
. #15) to the correct position by loosening
the two screws 4y-turn, setting the switch,
and tightening the screws firmly.
If at any time a change is made in
the low frequency power amps, the above
instructions must be repeated.
NOTE: The bass feedback control system
will not operate with a bridged or a
bridged-type power amplifier. Some amp-
lifier outputs may be optionally bridged
by the customer, while some are this way
by design. If you have questions concern-
ing your power amplifier, consult the
manufacturer of the amp. (Bridged and
bridged-type amplifiers wili work with
the mid-tweeter sections.)
