This compact 1U, 19-inch rack is capable of accommodating up to four diversity receivers - the minimum specification unit has two receivers; additional receiver modules can be purchased separately. Each receiver has an individual LCD display, showing RF levels for both sides of the diversity, audio level, low transmitter battery level, and name, frequency and audio output level for each artist.

Each receiver has 32 pre-programmed frequencies, and an increased switching bandwidth of up to 24MHz. There is a built-in active distribution amplifier, so only two antennae are needed to supply the signal for four receivers. With two racks cascaded together, only two antennae are needed, eliminating the need for additional splitters and combiners. Eight receivers can be operated from one set of antennae, a feature that is unique to the RK2040.

The RK2040 can be mains powered via an AC/DC adapter, or can be powered from any DC source with voltages from 10 to 18 volts (so, for example, a car battery can be used), via a four-pin XLR socket.

Four transformer balanced line-level outputs.

Built-in RS485 PC interface for remote monitoring and control via Audio Ltd’s custom designed monitoring PC based application. PC can be located up to 4000 feet away from the racks. Since up to 24 racks can be linked together, and only one cable is needed, up to 96 receivers can be monitored over one cable. The software to monitor the racks is included in the price.
