7. OUTPUT CONNECTIONS
[Output terminals]
Each amplifier has 3 speaker outputs: 4 Ω, 25 V and 70 V. Use only one of these outputs for connection.
Class 2 wiring may be used.
Note: Impedances indicated in the diagram mean total speaker load impedance.
[MOH output connections]
The MOH output is rated at 1 V / 600 Ω.
[OUTPUT 1 W output connections]
The OUTPUT 1 W output is rated at 1 W / 8 Ω.

Step 1. Unscrew the terminal cover.
Step 2. Strip 10 mm (0.39") of insulative jacket from the end of the speaker cable,
as shown in the figure at right.
Step 3. Connect speaker cables to the speaker output terminals.
Step 4. Replace the terminal cover.
Be sure to replace the terminal cover after connection completion.
Because high voltage is generated at the speaker output terminals,
never touch these terminals to avoid electric shock.
WARNING
The terminals marked with the symbol are hazardous live.
The external wiring to these terminals requires installation by an
instructed person.
