5. Wiring and Setting Up
The CMS 1201 is available in both a standard low-impedance variant (CMS 1201DC) and a low insertion loss
60 W line transformer-equipped version (CMS 1201DCt) for use on 70 V or 100 V distributed lines. The following
tappings are configurable on the transformer before screwing driver assembly into the back can:
70 V systems: 60 W / 30 W / 15 W / 7.5 W / OFF
100 V systems: 60 W / 30 W / 15 W / OFF
If later adjustment to the level is required the baffle can be hung from the can via a hinged edge, leaving both
hands free to make the required adjustment.
Tannoy’s focus on maintaining the highest standards of continuous product performance and reliability, through
uncompromising quality control of components and manufacturing processes, means you can specify and
install CMS 1201DC with confidence. As with all of Tannoy’s CMS in-ceiling loudspeakers, the CMS 1201DC
benefits from a 5-year warranty.
