|
1. Sensitivity
|
A: -57 +- 3dB
B: -63 +- 3dB
C: -69 +- 3dB
|
A: -60 +- 3dB
B: -66 +- 3dB
C: -72 +- 3dB

|
4. Frquency Range
|
20-12,000 Hz
|
40-10,000 Hz
|
|
5. S/N Ratio
|
More than 40dB measured with A curve
at 1 KHz at 1 micro-bar.
|
|
6. Self Noise Level
|
Less than 34dB SPL (Referred SPL 0dB=0.0002
micro-bar.)
|
|
7. Operation Voltage

1.5 to 15 VDC
|
|
8. Current Consumption
|
0.5 mA or less (Supply voltage 6V)
|
|
9. Polarity of Power Supply
|
(-) for ground
