AUDIO LTD.
RK2040 Rack System
Audio’s powerful rack-mounted receiver solution

Features
  • Compact 1U rack with four diversity receivers: 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 actor.
  • Up to 24MHz switching bandwidth on receivers: Each receiver has 32 pre-programmed frequencies and an increased switching bandwidth of up to 24MHz. It includes a built-in active distribution amplifier to allow all four receivers (or up to eight, by cascading two racks) to be fed from one set of antennae.
  • DC powered rack 10-18V: The RK2040 can be mains powered via an AC/DC adapter, or can be powered from any DC source with voltages from 10-18 volts (for example, a car battery can be used), via a four-pin XLR socket.
  • Remote monitoring from up to 4000 feet away: The rack features Audio’s custom-designed RS485 PC interface for remote monitoring of receivers. A PC can control and monitor all functions up to 4,000 feet (1,219.2 m) away from the racks.
  • Up to 92 receivers, one cable: Up to 24 racks can be linked together with only one cable needed to link to the PC. So up to 92 receivers can be monitored over one cable. The software to monitor the racks is included in the price.
