• All-metal housing suitable for commercial applications
• Mounting hardware included
• RF (radio frequency) Resistant Architecture
• Shock-absorbing polymer bushings included
• Inconspicuous design
DETAILS
The Astatic 210 is a miniature-boundary microphone designed for installation in security, ambient monitoring and observation applications. The output level is variable from -50dBv (3.2mV) to -10.5dBV (300mV) @ 1?Bar which is designed to interface with security cameras, digital video recorders and other observation and recording devices.
Astatic’s internal audio limiter circuitry tames high sound pressure levels and improves intelligibility by protecting the audio signal from distorting sensitive recording circuitry in cameras and digital recorders. The integrated volume control is located on the side of the microphone and is protected from tampering when the microphone is installed. The integrated 150Hz, 6dB/oct high-pass filter attenuates unwanted low frequency energy.
+9 to 24VDC (70mA) is required to power the microphone (not supplied). The connection is made through a removable 3.5mm terminal block plug connector on the opposite end of the microphone. The connector accepts DC power and outputs
an unbalanced, amplified signal.
The Astatic 210 housing is all-metal, designed for commercial applications. The threaded housing makes for easy installation into ceilings, walls, tables and other surfaces. Rubber isolation bushings and metal nut/washer hardware are also provided.

Architects’ and Engineers’ Specifications
The microphone will be an inconspicuous, omnidirectional, button-style, condenser boundary microphone designed for surface installation. The integrated limiter will maintain near/far signal integrity. The sensitivity of the microphone will be -50dBV (3.2mV) to -10.5dBV (300mV) @ 1 ?Bar. The frequency response will be 120Hz to 18KHz. The impedance of the microphone will be 50 ohms. The self noise will be 22dBA. The maximum SPL will be 100dB.
The microphone will include an integral 150Hz, 6dB/oct
high-pass filter to improve intelligibility. The microphone will have a removable 3.5mm terminal block plug with 180 degree wire-to-plug orientation, accepting 30 to 14AWG size wire.
The microphone will be externally powered with an 9 to 24VDC 70mA source (not supplied). The microphone element and electronics will be enclosed in a radio frequency resistant housing meeting or exceeding EN55103-2.
The microphone will be 3-3/8” [85mm] long including the euro-connector plug, 1-1/8” [28mm] in diameter and will mount in a 15/16” [24mm] diameter hole. The microphone will stand no more than 1/2” [13mm] above the boundary when the included rubber bushings are used. The net weight [mass] will be 2.4oz [.07Kg]. The packaged weight [mass] will be 5.4oz [0.15Kg]. The microphone will have durable matte-white urethane finish.
The Astatic model 210 is specified.
