Questions and answers
How to connect speaker to my UPA 550
To connect a speaker to the Unisound UPA-550FM:
1. Use the low impedance speaker terminals provided with impedance taps of 4, 8, or 16 ohms.
2. Connect speakers directly to these terminals if the distance is less than 50 meters.
3. Use 23/36 gauge or thicker cable for the connection.
4. Ensure the total impedance of all connected speakers is equal to or greater than the value specified on the terminal strip.
Alternatively, use the 100V line output for long-distance speaker connections.
