Rincon Research Corporation’s (RRC) DAA-04 is becoming deprecated. It is a wideband, four-input, distribution amplifier with four outputs for each input. The DAA-04 has adjustable gain for each input channel and an output power measurement capability to help set appropriate signal levels for downstream equipment. The DAA-04 can be controlled with a front panel LCD and over Ethernet, via a webpage or RRC’s control API.

When a smaller, portable system is required, consider the DAA-02P.
