CW 200

Architect & Engineer Specifications

The CW200 radio microphone system comprises of a rack mountable dual UHF band receiver contained in a single housing and two RF transmitters. The transmit / receiving frequencies covers UHF frequencies from 602 – 634MHz. These frequencies will be limited / tailored according to local transmission laws and will be factory set before being despatched to customers. The operating frequency bandwidth of 32 MHz is split into two and handled by each of the independent receivers A and B which will cover 16 MHz each with 32 selectable channels (total 64 channels) when the full frequency spectrum is being used. A multifunction back illuminated LCD display shows RF/AF, diversity strengths; transmitter battery level. The display will also show set up of selected channel, frequency, mute and other working status. In the event that a working channel has interference from local interference or if using a multi CW 200 system, the receiver has an Auto-scan and lock onto an open interference free frequency which can be quickly used to secure a free channel. The battery operated transmitters (2 x AA) have a simple on/off/function button and a multifunction back lit LCD display. Frequency changes are transmitted by Infrared link from the receiver to the transmitter making it a tamper proof system which is quick and easy to perform. Other features include: PLL (Phase Lock Loop frequency control) design ensures transmission reliability, "Noise Lock" squelch effectively blocks stray RF noises Each table top boundary layer transmitter contains 2 x Fixed-charge back plate electret permanently polarized condenser microphones positioned at 120 degrees angle of acceptance giving a cardioid polar pattern reproduction with superior offset noise rejection outside of the angle of acceptance. Transmitter continuous battery life using good quality alkaline batteries approx 10 hours. Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface and vibration pickup.
