C onnect an external amplifier-embedded speaker to the audio output cable.
Connect a stereo mini plug (ø3.5 mm) (Audio output is monaural.).
• Output impedance: Approx. 600 Ω (unbalanced)
• Recommended cable length: Less than 10 m {32.8 ft}
• Output level: –20 dBV
* Use an external powered speaker.
IMPORTANT:
• C onnect/disconnect the audio cables and turn on the power of the camera after turning off the
power of the audio output devices. Otherwise, loud noise may be heard from the speaker.
• M ake sure that the stereo mini plug is connected to this cable. When a monaural mini plug is
connected, audio may not be heard.
When connecting a monaural speaker with amplifier, use a locally procured conversion cable
(mono-stereo).
