<For microphone input>
• Recommended microphone (locally procured): Plug-in power type
(Sensitivity of microphone: –48 dB ±3 dB (0 dB=1 V/Pa,1 kHz))
•
Input impedance:
Approx. 2 kΩ (unbalanced)
• Supply voltage:
2.5 V ±0.5 V
• Recommended cable length:
Less than 1 m {3.28 feet}
<For line input>
• Input level for the line input:
Approx. –10 dBV
• Recommended cable length:

[4] Audio output terminal
Connect an external speaker* using a stereo mini plug (ø3.5 mm). (Audio output is monaural.)
• Output imped
ance:
Approx. 600 Ω (unbalanced)
•
Recommended cable length:
Less than 10 m {32.8 feet}
• Output level:
–20 dBV
IMPORTANT:
• Connect/disconnect the audio cables and turn on the power of the camera after turning off
