SHOCK HAZZARD.
OPERATION
The HDDS Master Control Module is the Master control center for distributed sound
systems using the HDDS technology. The Master Control Module includes six zones
that can be used independently or can be linked to work together allowing the system
designer the flexibility to set up any system with the desired configuration. The block
diagram below shows the basic configuration of the SM652 Surface Mount Speaker.
The speaker receives power and audio over a Cat5 cable connected to the Master
Control Module, internally converts the AC power to plus / minus 15VDC and 30VDC to
power the amplifier. The audio signal is fed to a precision differential amplifier to
remove any common mode noise, equalized and fed to a D-CAT power amplifier circuit
and crossover to drive both the woofer and tweeter in the cabinet. The SM652 also
includes a built in liming circuit which limits the maximum audio output. The limiter is
set as a protection circuit that will allow the SM652 to reach its maximum output
without excessive clipping to protect the internal components from failure. The SM652
also includes thermal tracking and will mute the output if the internal amplifier
temperature exceeds 120 degrees centigrade.
The HDDS SM652 is available is both black and white. Both models include a front
mounted blue power indicator LED, which illuminates when power is on.
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.
SPEAKER POWER:
The HDDS system distributes low voltage Alternating Current over the Cat5 cable plus
high level balanced audio and is capable of greater than 48 watts continuous output
power per SM652 speaker. Each of the Master Control Modules three outputs A, B and
C are capable of delivering up to 7 amps of output current. With a typical power per
speaker of 10 watts each speaker will average on the order of 400mA, which means
that 12 speakers would require 4,800mA of current. Installed systems that require
more output power per speaker simply require that the number of speakers per output
A, B and C be reduced so as not to exceed the maximum of 7 amps available. The
current consumption at full power (48 watt continuous) will require over 1.5 Amp of
power per speaker. In order to allow the full 48 watts of power, where higher output
levels are desirable, the number of speakers per A, B and C outputs on each zone
needs to be limited to a maximum of 4 speakers. Reducing to 20 watts of power per
speaker, a maximum of 8 speakers per output can be connected to each A, B and C
zone output. With longer runs of cable exceeding 300 feet the cable voltage drop will
start to become a design factor. The Cat5 cable will start to limit the total power
capability once you exceed 100 feet of cable. Where maximum power output is critical
it is recommended to use Cat6 cable since the gauge per wire is 22 vs 23 with Cat5.
This increase will reduce the voltage drop over longer runs.
Cat5 Connections
The figure below shows the connections for each output A, B and C of each zone output
on the Master Control Module and also connections between each SM652 speaker.
Connections are done via standard Cat5 cables where pins 1 through 8 are connected
common to the same pins 1 through 8 at each end. As shown below two wires in the
Cable are use for balanced audio and 6 wires are used for power with two providing
ground and two for each of two 22VAC power signals fed down the cable.
Mounting the SM652
Refer installation to a qualified installer to ensure proper mounting to overhead
structures. The SM652 includes a U bracket for easy install allowing the speaker to
swivel for proper alignment and aiming.
