9.3. Speaker Output Signal Connections
9.3.1. High-impedance 100 V line speaker connections
9.3.2. High-impedance 70 V line speaker connections
9.3.3. Low-impedance speaker connections
The unit can be connected to high- or low-impedance speakers. Class 2 wiring may be used.
Using the supplied Large type removable terminal plug (5 pins), connect the speaker line to any pair of terminals
from among the following three combinations.
Also, perform the impedance setting using Switch 4 of the DIP switch.
