Notes:
1. Average over stated bandwidth. Measured in an IEC bae in an Anechoic Chamber
2. Unweighted pink noise input, measured at 1 metre on axis
3. Long term power handling capacity as dened in EIA - 426B test
4. The 70/100 V transformer for the CMS 603 DC/ICT PI models is mounted in the optional PI Backcan.
