DESCRIPTION
The ACM" 2isa very small
unidirectional condenser microphone
designed primarily to be suspended
ove' choirs instrumental ensemb'es. or
stage areas for sound reinforcement
and'or recording
The small size allows one or more
ACM 2 mics to be hung cr "flown' m
virtually any application with no
distract on or sight line obstruction. It
can also be easily concealed in
scenery or props when desired
T-- very uniform cardioic polar
response is highly effective in
suppressing feedback and unwanted
sounds, as well as in minimizing
uncesiraoie coloration of off-axis
sources.
Since the ACM 2 is primarily designee
to be hung somewhat above the
protection axis of tne performer a
SUOlly rising nigh frequency response
characteristic is incorporated nto the
design This characteristic
compensates tor the high frequency
roll-off inherent in this kina ot pickup.
Extens ve shielding provisions are
incorporated to guard against RF and
other electrical interference
