Input sensitivity switch
LINE
(normal mode): the input sensitivity is set to LINE level (+4 dBu), suitable for a
mixer output.
MIC:
the input sensitivity is set to MIC level, suitable for the direct connection of a
dynamic microphone. Do NOT use this setting when connected to a mixer output!

FLAT / BOOST switch
FLAT
(released switch, normal mode): no equalisation is applied (flat frequency
response).
BOOST
(pushed switch): ‘loudness’ equalisation, only recommended for background
music at low volume levels.
7
LIMITER LED
The internal amplifier has a limiter circuit to prevent clipping and overdriving transducers.
It blinks when the signal level reaches the clipping point, causing the limiter intervention.
If it is steady lit, the input signal level is excessive and should be reduced.
8
SIGNAL LED
When lit, it indicates the signal presence at the audio input.
9
STATUS LED
When blinking, it indicates the internal protection intervention due to thermal drift (the
amplifier is muted).
