Building on the foundation of the Com-Tech

CTs Series offers new
fl exi bility and value for installed sound. The
Com-Tech Series was the fi rst to offer
independent selection of high- and low-
impedance opera tion for a specifi c channel, and
CTs Series amplifi ers continue that tradition,
with power levels and features carefully chosen
to perfectly integrate into fi xed install design
requirements.

Modern power amplifi ers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.

In addition, CTs Series amplifi ers include a
