Clean the dust filter at least once every quarter after the initial cleaning; do not remove the filter, otherwise the product’s lifespan may be reduced.
First verify that the power switch is on and the input signal is correctly connected; if the signal is correct but there is still no sound, check the NL4 connector and try a different channel or replace the connector.
In stereo mode the amplifier is recommended for 8 Ω loads; in bridge mode it should be used with 16 Ω loads.
