1. Open the wiring cover at the back of the speaker can to access the Euro type connector
plug and socket.
2. For connection to an amplifier, use pins 1 and 2:
• Pin 1 is positive
• Pin 2 is negative
For connection to additional speakers in a distributed line, pins 3 and 4 are in parallel where:
• Pin 3 is negative
• Pin 4 is positive
3. Close the wiring cover and tighten both screws on the cable clamp. Use the rotary
switch located on the front of the unit to select whether you wish to use the speaker in a
low-impedance or distributed-line application.
THE SPEAKER IS SUPPLIED IN LOW IMPEDANCE MODE. NEVER CONNECT THE
SPEAKER TO A 70/100 VOLT AMPLIFIER WHILE IT IS SET FOR LOW IMPEDANCE.
All CMS 801 models use a 60 W transformer. When using distributed-line systems,
the transformer can be tapped at 60 W, 30 W and 15 W, with an additional 7.5 W tapping
for 70.7 V line systems.
