Features
The SCA-M30 Ceiling Microphone is designed with high performance and durability
especially for security applications, with the following features.
Optimized for use with Sony network cameras
The SCA-M30 supports “plug-in power” (accepting dc bias voltage for the microphone
through the audio cable), and provides compatible audio electrical characteristics
(microphone input signal level, dynamic range and impedance).
High-fidelity design
• Supersensitive unidirectional electret condenser transducer.
• Acoustic shielding construction suppresses noise from the sides and back, while clearly
picking up sounds from the front.
• Pickup direction is aimed simply by rotating the grill section.
• A low-cut filter is included to suppress low-frequency noise.
Designed to endure external vibrations
• Rubber-cushioned mounting suppresses pickup of vibration noise.
• No-hole upper case design suppresses direct noise pickup from ceiling spaces.
• Folding mounting springs suppress pickup of direct external vibrations.
Simple installation
• The microphone unit mounting springs require only a hole made with standard tools
(90 mm to 100 mm (3
5
/
8
inches to 4 inches) diameter).
• The output signal connects to the microphone input jack on a Sony Network Camera
(supports 2- or 3-pin plug-in power supply).
• A bracket is provided for mounting on ceilings where a large hole (90 mm to 100 mm
(3
5
/
8
inches to 4 inches)) cannot be provided.
Selectable input sensitivity
Input level can be selected from 0 dB (H), –6 dB (M), or –12 dB (L) to match the requirements
of different connected devices.
