ISP Technologies SM 652 W/B - Manual (Page 5)

Rear Panel
The rear panel includes two RJ45 connectors one for input and one for output. Connect
the input to the output connector on a HDDS Master Control Module. A Cat5 cable is
used to connect the output connector to another SM652 or to connect to any other ISP
Technologies HDDS powered speaker.
The SM652 will typically pull less than 500 milliamps of current from the output of the
Master Control Module with typical listening levels. At maximum level the SM652 can
pull in excess of 1 amp of current. If maximum output power is desired it is
recommended to limit the number of serially connected SM652 speakers on a single
50ft run of Cat5 cable to no more than 4 speakers. With longer runs of cable the limit
will be reduced in order to achieve full output power. Connect the SM652 to any one
of the A,B or C outputs on the rear of the HDDS Master Control Module as shown
below.
