Telco Line and Telco Set Ports11. : Two RJ-11 connectors telephone ports. The Telco Line port connects an
analog telephone line to Converge Pro devices. The Telco Set port provides a pass-through connection for
telephone handsets (880TA, 880T, 840T, TH20).
NOTE: The Telco Set port is not available for use when the telephone hybrid is off-hook.
Amplifier Terminal Block (880TA, SR 1212A)12. : 12 speaker terminals used to connect an external speaker
(70/100 v). Four, 35 Watt internal power amplifiers eliminate the need for an external power amplifier.

or external equipment while the amplifier is power is on. Class 2 wiring is required.
Maintain the correct polarity on output connectors. (For example: Channel 1 70/100V
speaker lead connects to amplifier’s channel 1 70V or 100V terminals. Channel 1 GND
(or Common) speaker lead connects to amplifier’s channel 1 GND terminal. Repeat
this procedure for each channel.
