 600Ω output impedance drives a high impedance load
such as “Line in” of a PA system, Music on Hold input of a
key system, transmitter input, etc.
 8Ω output impedance drives standard 8Ω speakers.
 Each output volume is adjustable up to the following
levels:
-
8Ω - 1.0W@2.8Vrms.
- 600Ω -
13mW@2.8Vrms (8Vpp or =9dBm).
