Lo-Cut Horn Protect Switch
:
Turn the switch ON whenever horns are used in the system. This function will protect the horn voice coils from damage by filtering
out low frequencies inherent in some types of music when played at high power settings. (Set at factory in ON position.)
Peak Level Indicator
:
Occasional flickering of the LED indicates momentary peak levels, and is a normal operating condition. Steady illumination of the
LED is an indication that an overdrive (clipping) condition may exist. If distortion is audible, then lower the appropriate input
volume control, and/or the master volume control.
Limiter ON-OFF Switch:
A limiter is desirable for many paging applications because it will help the paging volume sound uniform (compensates for the
differences of loudness in people's voices). For live program applications, (i.e., house of worship, auditoriums, etc.) it is often
desirable to defeat the limiter function. This results in more "natural" (wider dynamic range) sound reproduction. Thus, the AA
Series Amplifier may also be used in general purpose commercial/PA applications (set at the factory in the ON position).
Music Mute ON-OFF switch:
In certain applications (i.e., noise masking, tone signals, etc.), it is often desirable to defeat the auxiliary input mute function. This
results in the auxiliary input signal mixing (occurring simultaneously) with telephone paging or microphone input audio. For
example, a 4 channel MIC/Line mixer could be patched in at this point and it's signal would not be muted by signal on the 2 other
microphone inputs. Thus a 6 microphone system for conferences, etc., is achieved. (Set at factory in the ON position).
CAUTION: To prevent electrical shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless
the blades can be fully inserted to prevent blade exposure.
Attention: Pour prevenir les chocs electriques ne pas utiliser cette fiche polarisee avec un prolongateur, une prise de courant out
une autre sortie de courant, sauf si les lames preuvent ete inserees a fond sans en laisser aucune partie a decouvert.
MAINTENANCE:
