Setup, Compatibility & Care
Installation of the IWA230B should be performed by a qualified electrician, as the unit connects directly to local mains power (100-240V). Always ensure the mounting location allows for adequate airflow within the wall cavity to prevent heat buildup, despite the high efficiency of the Class-D design. Use the provided 3m speaker leads to connect your preferred 4-8 Ohm speakers using the Euroblock terminals. To clean, simply wipe the surrounding wall area with a dry cloth; the amplifier itself is maintenance-free once installed. Periodically check that all cable connections remain tight if the unit is installed in an area subject to vibration.
