down to the low frequency limit in its specification with virtually no saturation.  In 
addition, the insertion loss of less than 0.5 db is extremely low.  This results in less heat 
generation, higher power transfer and more speaker efficiency. 
Do the EVID ceiling speakers work with both 70v and 100v systems? 
Yes all ceiling speaker models work on both 100v and 70.7v lines.  
What are the power taps for the various EVID “t” models”? 
•  C4.2 and the C8.2: The power taps are 30w, 15w, 7.5w, 3.75w and 1.88w both 
70.7v and 100v. 
•  C8.2HC and the C10.1: The power taps are 60w, 30w, 15w and 7.5w at both 
70.7v and 100v. 
A rotary switch on the baffle selects the taps for all models. The switch is marked 
showing the positions to use for the settings at 70v and 100v. 
What equalization should I use for EVID ceiling systems? 
The proper equalization settings depend on many factors, such as the quantity of 
speakers, the room characteristics, the typical operating level, the residual background 
noise in the venue, and the type of audience.  The wide frequency response and high 
power handling of EVID systems lets you use a wide variety of equalization settings. 
EVID Ceiling Speaker System Designs 
What are some typical systems designs incorporating EVID series 
speakers? 
The EVID series of ceiling speaker systems are especially well suited to working with the 
MA series mixer amps or the CPS-1, CPS-2 and CPS2T power amplifiers.  In the 
following section  there are a number of suggested installation examples for a variety of 
environments incorporating EV amplification products. 
Please note:  The equipment lists which follow do not list other required pieces 
commonly used in sound installations such as source playback equipment and paging 
hardware.
