ENNIS, TEXAS 75119 U.S.A.

General Description

The Atlas Sound SM8CXT and SM12CXT are designed for 8Ω and 70.7V distributed

applications where high output and accurate sound reproduction are required. Both

models feature a unique compact cabinet design with multiple

1

⁄4"-20 inserts to

allow easy suspension or wall mounting. The dual angle design also allows the sys-

tems to be used as a short or long throw stage monitor system

The SM8CXT includes the Atlas Sound 8CXT60 compression driver coaxial loud-

Amplifier Considerations for 8Ω Operation

Note:The input barrier strip includes a jumper which when removed activates the

8Ω input on the barrier strip and the Speak-On jacks.

Consult your amplifier owner’s manual to confirm power output at the rated imped-

ance.AtlasSoundspeakersystemspecificationslistRMSpowerhandling.As

For increased headroom and dynamic reproduction, the amplifier’s output should

match or exceed the peak power rating of the speaker system.

adjustedproperly,amplifieroutputmaymeet,butshouldnotexceed2xtheRMS
