to the remote CT-10 series amplifiers. Please note that the
RJ-11 jacks are polarity sensitive. Pin
4 must be grounded, and Pin 3 must
be supplied with a positive voltage
pull up (positive with respect to
ground). Refer to Figure 3.1 for RJ
jack pin assignments.* The maximum signal that can be exposed to
the RJ-11 jacks is 35 VDC or 25 VAC.
(RJ-11 connectors are available from
the Crown Parts Department.)
