The DCR822 digital receiver provides the highest level of RF and audio performance available with a versatile feature set in a compact design for field and location production. Settings can be made from the front panel with tactile buttons and LCD interface, making the unit ideal for use in portable bag systems and on sound carts. An RF spectrum analyzer and SmartTune are built into the receiver to alleviate interference problems in an increasingly congested RF spectrum.
The mechanical design of the receiver fits into the same dimensions as the older UCR411A and combines field-proven features developed over many years of experience in motion picture and television production. To decrease weight, the DCR822 provides a dual channel receiver in one unit powered by 4 AA Lithium batteries or external DC. The receiver is also equipped with both an IR port and microSD card slot for data transfer. The machined aluminum housing and panels are surfaced with a hard-anodized finish with laser etched markings to withstand the rigors of field production.
