Product Description

The Clockaudio CS4-RF is a new addition that completes the CS-RF Series microphone family, offering a 4-element boundary layer microphone in a single housing. Like the CS2-RF and CS3-RF, the CS4-RF offers half cardioid polar patterns and a bottom cable exit.

The CS4-RF can be positioned in the centre of a round conference table, ideal for 360 degree pick-up, giving maximum coverage from a small footprint (example. positioned on a square or round table with 4 to 8 people equally positioned).

The CS4-RF is a quad 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 CS4-RF is also available in other customised colours and special finished upon request.

The CS4RF is supplied fitted with a 2 metre cable (with open-ended termination) and 4 integral Phantom Power adapters which accept 9 to 48 volts DC.

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.
