Atlas Sound does not assume, or does it authorize any other person to assume or extend on its behalf, any
other warranty, obligation or liability. This warranty gives you specific legal rights and you may have other
rights that vary from state to state.
Please note that the input terminal cup includes corner threaded
inserts to accommodate standard four square electrical box
cover (RACO #753 or equivalent). The cover allows for conduit
connections directly to the input cup.
WIRE GAUGES (4 OHM OPERATION)
For very short distance speaker cable runs (less than 25') #16-
Gauge, stranded, twisted pair speaker cable may be used. For
speaker cable runs between 25' and 75', #14-Gauge, stranded,
twisted pair speaker cable is recommended. For speaker cable
runs greater than 75' #12-Gauge, stranded, twisted pair speaker
cable is necessary.
WIRE GAUGES (70.7V OPERATION)
Use 18/2 stranded twisted (plenum rated if necessary per local code)
for speaker cable runs up to 2000'. For distances over 2000' please
consult your cable supplier for suggested wire gauges.
OVERHEAD SUSPENSION INSTALLATION
Suspension or flying speaker systems requires training and
expertise. Improper rigging of a flying speaker may result in
injury, death, equipment damage, and legal liability.
Installation must be carried out by fully qualified installers, in
accordance with all the required safety codes and standards that
are applied at the place of installation. 5:1 design factor is a
generally accepted design standard, however, legal require-
ments for flying vary by municipality. Please consult you local
safety standards office before installing any product. We also
recommend that you thoroughly check any laws and bylaws
prior to installation.
If you lack the skills, training, and proper ancillary equipment to
fly a speaker system do not attempt to do so.
The Atlas Sound SM8SUB70-B system contains multiple
1
⁄4”-20
inserts to allow most any suspension angle conceivable. ONLY
LOAD RATED & CERTIFIED HARDWARE (EYEBOLTS &
CABLE) SHOULD BE USED IN THE INSTALLATION OF THIS
PRODUCT.
These products are available from:
ATM Group, Inc., 21000 S. Wilmington Avenue Carson, CA 90810

Loudspeakers flown in theatres, nightclubs, conference centers or
other places of work and entertainment must be provided with an
independent, correctly rated and securely attached secondary
safety – in addition to the principle suspension point(s). This sec-
ondary safety must prevent the loudspeaker from dropping more
than (6") should the principle suspension device fail.
SURFACE MOUNTING
The SM8CBKT-B is an Optional C-bracket for wall/surface mounting
of the SM8SUB70-B.
Whenever the loudspeaker is mounted to a
surface using the optional “C” bracket the installer must ensure
that the surface is capable of safely and securely supporting the
load. The hardware employed must be safely and securely
attached both to the loudspeaker and the surface in question,
using only the mounting holes. If you are unsure of the integrity of
the mounting surface please seek assistance from architects,
structural engineers or other specialists.
OMNIMOUNT™
Inserts are provided on the top, bottom and back of both models
to accommodate Omnimount™ brackets. Use the Omnimount™
30 series for the SM8SUB70-B.
STAND MOUNTING
The optional Atlas Sound SSA7 can be used with the top and bot-
tom cabinet inserts to facilitate stand mounting for portable use.
HEARING DAMAGE
CAUTION: These professional loudspeaker systems are capable
of generating very high sound pressure levels. Use care with
placement and operation to avoid exposure to excessive levels
that can cause permanent hearing damage.
OUTDOOR USE
The systems should not be flown or used in permanent outdoor
applications under any circumstances.
FUSE PROTECTION
Units are shipped with a 20A fuse installed. This high current fuse
functions as a through connection and offers no protection. If fuse
protection is desired please replace the 20A fuse with a 4A fuse
slow-blow type (AGC or 3AG type). Please note that for 70V opera-
tion the internal transformer with a maximum tap of 60 watts nullifies
the need for fuse protection.
