4. LIMITER LED – Illuminates (red) when the built-in limiter is activated to protect and avoid damage to the amplifier or
loudspeaker. If the signal level at any frequency is too high, or the amplifier is too hot, the limiter is activated and the
LED is illuminated.
5. POWER LED – Illuminates (blue) when power is applied to the unit and the ON/OFF switch is in the ON position.
NOTE: Unless the gain controls of all active inputs are set to 0 dB, the output signal from the MIX OUT (POST GAIN) will not
be at the same level as the input signal. If a “slave” speaker is intended to playback at the same level as the “master” speaker,
the gain control on the “slave” speaker should be set to0 dB.
