installation components. Doing so demonstrates your
appreciation for high quality, high performance audio
and video reproduction. The DSSM’s take the standard
set by the original ISM products to a whole new level
and sets a new standard in design, flexibility and
affordability-for the installation of multi-source, multi¬
zone speaker systems in any installation.
The DSSM8, DSSM6 and DSSM4 are low-profile
speaker distribution systems with individual on/off
selectors for each listening zone and the ability to
select either of two speaker-level signal sources.
The DSSM8 distributes either of two stereo speaker-
Use of the Protection Circuit Switch
It is recommended that if you are using impedance
matching volume controls in conjunction with your
DSSM Speaker Selector, you should ensure that
the Protection Circuit switch on the rear panel is
in the “OFF’’ position. The DSSM Selectors ship
with the switch preset for the “OFF” position.
If you turn all of the remote volume controls down to
fully attenuate the level in all zones, and leave all zones
in the “ON” position on the DSSM with your amplifier
set to a reasonably high level you could cause the

- 432mm x 152mm x 45mm
- 216mm x 152mm x 45mm
level signals to eight stereo listening zones. The DSSM6
distributes either of two stereo speaker-ievei signals
to six stereo listening zones. The DSSM4 distributes
either of two stereo speaker-level signals to four stereo
listening zones. All DSSM’s feature a manually
activated power protection circuit switch located on
the rear panel, activating four pairs in the DS$M4
DSSM6, or six pairs in the DSSM8, of high power
resistors (two or four 10ohm/15 watt resistors per
channel, per source component wired in parallel
providing up to 50% more power handling capability
than the competition) while maintaining a stable 5 ohm
impedance load to ensure amplifier stability.
DSSM Speaker Selector and your amplifier to severely
overheat. Disengaging the Protection Circuit Switch
will bypass the resistors and prevent this damage. Be
aware that the maximum power rating of an DSSM4
or DSSM6 Speaker Selector with the Protection Switch
“Off’ is 140W per channel, and 200W per channel for
the DSSM8. Any DSSM switcher returned with burnt
resistors will not be covered under the one year limited
warranty, as this condition clearly shows abuse. For

Installation and Connection Procedures
The polarity connections for the input and output screw-type
speaker terminals are clearly marked on the rear panel. The
modules which allow the wires to be connected can be removed
for ease of wiring. Please connect the speaker cable to the
appropriate “+/-“ terminals. These terminals will accept up to 14
gauae speaker cable and we highly recommend utilizing at minimum
a 16 to 14 gauge speaker cable. Note: Separate Left and Right
ground paths ensure compatibility with all amplifiers, even when
jjpf) Strip 1/4" or 6mm insulation from the 14
6mm
used in bridged mode! Route the speaker cables from each
speaker zone and the amplifier to the DSSM speaker selector.
Strip 1/4” (6mm) insulation from the end of the cable and twist the
exposed end to avoid fraying. Loosen the screw on the appropriate
speaker terminal and insert the stripped end of the cable into the
speaker terminal, Be sure to observe proper “+/-“ polarity when
connecting the speaker cables. Re-tighten the screw to clamp the
cable in place. Gently puli on the cable to ensure it is secure and
properly connected.
-16 gauge speaker wire
DSSM switchers have the ability to select between “A" and “B”
sources. There is an 8-position plug on the left rear of the unit
which is labeled "INPUT”. This is where the speaker level inputs
from the two sources (“A" and “B”) are connected. Attach the wires
in the same manner as the speaker wires connect to the outputs
of the DSSM unit (see above for details).
/ • \ Note: Always insure that both source components
are unplugged and powered down before making these
connections.
The system is now ready for testing. Turn on the sound system
and set the amplifier's volume control to a moderate level. Sound
should be heard from each zone when its button is depressed.
Please check each zone appropriately including proper left and
right connections by activating each zone with the balance adjusted
to full left and then to full right. If you have connected two sources
(“A” and “B”) test each zone's source switching by depressing the
button on the front panel. If the button is in the “in” position, the
source is “A”. If the button is in the “out” position, the source is
“B". If you have only one source connected, the buttons should
all be set to “A”. Attach the custom die-cut labels provided to the
rectangular buttons of the DSSM’s referencing each button to an
appropriate zone within the installation.
Installation Precautions
Under normal circumstances do not leave the “Power Protection
Circuit” disabled unless your amplifier can handle the combined
impedance of all zones activated. For example, an DSSM6 with
six pairs of 8 ohm speakers will present the amplifier with a 1.33
ohm load per channel with the power protection circuit switch
“OFF” position. This may damage your amplifier or cause it to
thermally protect itself by shutting down. With the power protection
circuit switch “ON”, the amplifier will see 6.33 ohms per channel,
which will not present a problem for most amplifiers. Please consult
your authorized dealer and/or the owner’s manual for your amplifier
for complete details.
Power handling without the protection circuit switch engaged is
140 watts per channel for the DSSM4-/DSSM6 and 200 watts per
channel for the DSSM8. Power handli ng with the protection circuit
switch engaged is 70 watts per channel for the DSSM4/DSSM6
and 100 watts per channel for the DS SM8. Never place the
DSSM’s where they will be exposed to excessive moisture or heat.
Allow for 1 inch of clearance above the top of the unit.
