Specification Notes


[ 1] Typical.
[ 2] TEDS Capable Digital Memory and Communication, compliant with IEEE P1451.4
[ 3] Measured with an 18 pF reference microphone.
[ 4] Per IEC 61672-1:2002 "Sound Level Meters" Class 1
[ 5] Overload detection is in front of filters. Positive pulses at output indicate overload.
[ 6] Error from ideal A weight re 1 kHz.
[ 7] 20 Hz to 20 kHz
[ 8] re 1 kHz
[ 9] Without Filter or +20 dB gain engaged.
[ 1] Typical.
[ 5] Overload detection is in front of filters. Positive pulses at output indicate overload.
