INTRODUCTION
Thank you for your purchase of the ISP Technologies High Definition Distributed System
SM650 Surface Mount Speaker. This product provides a new level of performance in
distributed audio systems allowing greater system flexibility and easy installation of
distributed sound. All connections are made via Cat5 RJ45 connections making
installation of systems faster and easier using the SM650.

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 SM650 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, filtered with a crossover circuit to produce a low pass
and high pass signal, equalized and fed to D-CAT power amplifier circuits to drive both
the woofer and tweeter in the speaker. The speaker includes an onboard level
adjustment that allows simple balancing of installed systems.
The HDDS SM650 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. The
SM650 also includes a level control and a power jack that allows connection to an
external 18VAC power adaptor available from ISP Technologies. 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 SM650 or to connect to any other ISP
Technologies HDDS powered speaker. The power connection on the back of the
SM650 can be used to power the speaker as a stand-alone speaker or can also be used
to add additional power if a long run of Cat5 cable is used. The system is designed to
allow both the Cat5 cable to supply power plus the external adaptor at the same time
without the risk of damage. The internal power supply will simply derive power for the
power source with the highest voltage available.
The SM650 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 SM650 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 SM650 speakers on a single
50ft run of Cat5 cable to no more than 5 speakers. With longer runs of cable the limit
will be reduced in order to achieve full output power. Connect the SM650 to any 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 30 watts continuous power per
speaker SM650. Each of the 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
consume 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 (30
watt continuous) will require over 1 Amp of power per speaker. In order to allow the
full 30 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 limiting the maximum number 5.
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 150
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 75 feet of cable. Where
maximum power output is critical a more precise calculation can be done by following
the speaker consumption guide.
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 SM650 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 SM650
Refer installation to a qualified installer to ensure proper mounting to overhead
structures. The SM650 includes a U bracket for easy install. When mounting requires
additional swivel mount capabilities use ISP Technologies SM10 swivel mount bracket
shown below.
The swivel mount bracket threads into one of the threaded inserts on the back of the
SM650 and allows wall mount or ceiling mounting of the speaker with full swivel
capabilities. The SM10 kit also includes two toggle bolts for mounting to drywall or
other structures.
