SA 277 outdoor
microphone kit
Set of weather protection for SV 12L preamplifier and ACO
7052E microphone.

ACO 7052E
microphone
Pre-
polarised 1/2” condenser microphone with sensitivity 35
mV/Pa.
Note: With the use of Outdoor Airport type compensation filter (filter must be
defined in SVAN 977, see Chapter
) the acoustic characteristics of SA 277
conforms the class 1 sound meters and IEC 61672:2002 standard for the direction 0
degree (normal direction regarding the microphone membrane). With the use of
Outdoor Environmental type compensation filter the acoustic characteristics of
SA 277 is switched to the direction 90 degree (parallel to the microphone
membrane).
