Product Description

The Clockaudio CS3-RF is a high performance Boundary Layer Microphone for desktop, tabletop and boardroom installations.

The CS3-RF model features 3 microphone elements, each with a half-cardioid polar pattern and, therefore, is ideal for 270 degree pick-up; for instance, positioned on the end of a boardroom table for voice pick-up of people positioned front, left and right.

If the participant at the end of the table is further away, it is then possible to use a combination of a CS2-RF (dual element) and CS1-RF (single element version) to accommodate this situation.

The CS3-RF is a tri-element Condenser Boundary Microphone which is manufactured in solid brass (finished in Black Nextel) to give a true quality feel and assurance of a robust, long lasting microphone.

The CS3RF is supplied fitted with a 2 metre cable (with open-ended termination) and 3 integral Phantom Power adapters which accept 9 to 48 volts DC.

This professional Boundary Microphone also includes RF immunity filters which eliminate the unwanted noise and interference caused by the GSM frequencies emitted by handheld / wireless devices such as smartphones.

Boundary Layer Microphone with a Half Cardioid Polar Pattern. Designed to be placed in the middle of the conference table, with the participants facing the condenser element. Can be permanently mounted using the hollow bolt and nut provided. Inbuilt Phantom Power Module.
