b'18 Clockaudio -Boundary Cardioid MicrophonesCS-RF Seriesboundary layer professional microphonesThe CS Series (Consultant Series) was developed as a result of input and recommendations from key consultants in boardroom AV integration. The goal was to minimise the number of microphones on the conference table, but also keeping in mind performance, ease of installation and aesthetics, essential considerations in such projects. CS 1-RF - single element boundary microphoneThe CS 1-RF is a single element microphone, the CS 2-RF is a dual element boundary layer condenser microphone, with a half-cardioid polar pattern, designed to be placed in the middle of the conference table, with each element facing the participants. The CS 3-RF microphone has the same characteristics as the CS 2-RF with the addition of a third element. This microphone is to be positioned closer to the end of the conference table in order to capture the participants facing each other and also the participant sitting at the extremity of the table. If the participant at the end of the table is further away, it is then possible to use a combination of a CS 2-RF and CS 1-RF to accommodate this situation.The CS 4-RF completes the CS-RF Series microphone family, offering a 4-element microphone in a single housing. The CS 4-RF can be positioned in the centre of a round conference table, giving maximum coverage from a small footprint. These microphones are made of solid brass and finished in a durable non-reflective black Nextel or satin nickelCS 2-RF - dual element boundary microphoneand include a 2m cable with open-ended termination. The Phantom Power Adaptor (PPA) is incorporated in the brass housing and will accept 9 ~ 48v DC (Phantom Power). The microphones accommodate bottom cable exit, for permanent mounting in boardroom situations.Half cardioid polar patternFully balancedNon-reflective black Nextel or satin nickelThe CS series available in other customisedcolours and special finishes upon requestModels:CS 1-RFsingle elementCS 4-RF - quadruple element boundary microphoneCS 2-RFdual element CS 3-RFtriplle element CS 4-RFquadruple elementModel:CS-RFMicrophoneCondenser (back electret)Polar PatternHalf cardioidFrequency Response50Hz ~ 18KHzSensitivity-37dB 3dB @ 1KHz (0dB=1v/Pa)Impedance200WPower Requirements9 ~ 48v Phantom PowerS/N Ratio69dB(A)TerminationOpen ended multi-core cableCS 3-RF - triple element boundary microphone= RF-Immunity Version'
