Recommended Accessories

Radio Design Labs' RU-UDA4 is part of the group of RACK-UP products from Radio Design Labs. RACK- UPS feature the advanced circuitry for which RDL products are known, combined with accessible user-friendly controls and displays. The ultra compact design permits high density installations, with THREE products mounted in a single rack unit! Single RACK-UPS can be mounted right where they are needed using the adhesive mounting method popularized by RDLs STICK-ON series of products. Optional brackets permit mounting a RACK-UP module above, below, or in front of any flat surface.

The RU-UDA4 is the optimum choice where connectorized, unbalanced line level distribution needed. This unit features two separate, isolated channels. The RU-UDA4 may be used in stereo applications, or as two individual monaural distribution amplifiers. The input signals are buffered through output line drivers, providing 4 separate line-level unbalanced outputs for each of the two inputs.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

The RU-UDA4 performance is tailored around industry standard -10 dBV input/output levels. Excellent frequency response, phase response, distortion and low noise performance combine to produce the audio clarity and precision for which RDL products are well known.

Standard phono input and output connectors are firmly attached to the steel front panel for superior mechanical integrity. The 24 Vdc power supply input is provided on full-size barrier block connections on the rear panel. The RU-UDA4 may be operated on 12 volts with a reduction in headroom.

Features:

  • Stereo Unbalanced Audio Distribution
  • Unity Gain on Both Channels
  • 4 Outputs per Channel
  • Stand alone or Rack mountable
  • Exceptional Audio Performance
  • 1/3 Rack, High-Density Rack Mounting
