  • Page 13: Installation

    INSTALLATION Speaker Connections This amplifier supports four separate output zones, each driven by a dedicated 120-watt amplifier. You can connect speaker arrays with an overall 4-ohm impedance or constant voltage speaker arrays at 70 or 100 volts. 1. Create up to four individual speaker arrays. If using low-impedance speakers, ensure that the overall impedance of the array is 4 ohms.
