RDL Introduces the First Full-Featured Energy-Saving Mixer Amplifiers

 RDL is excited to announce that the new HD Series 35 Watt Mixer Amplifiers are now shipping. RDL HD Series ultra high efficiency amplifiers are the world’s first full-featured environmentally conscious “green” mixer amplifiers for commercial installations. An internal low-power-consumption processor monitors usage demands to completely shut down internal circuitry for maximum power conservation and extremely low long-term operating cost. These amplifiers draw less than 1 Watt of mains power while in standby mode and automatically turn on when an audio input signal is detected. This coupled with a highly efficient Class-D output stage makes these the most energy efficient mixer amplifiers available.

The HD-MA35U/A is a 4 input mixer amplifier, the HD-PA35U/A is a single input amplifier and the HD-RA35U/A is a 4 input remote controlled mixer amplifier. All models are available with either a 4/8 Ohm or constant voltage (25, 70 or 100 V) output. All models have built-in VCAs designed for use with RDL or other OEM remote controls.
HD Series amplifiers are ideal for a wide variety of applications including background music, paging, education, house of worship and corporate environments. These products include studio quality microphone input stages, line-level transformer isolation, equalization, remote control capability and integral analog compression coupled to sonically pleasing analog-filtered high efficiency Class D output stages. These mixer amplifiers are designed and manufactured in the U.S.A. using the most advanced automated manufacturing and testing processes for years of reliable high performance and cost savings.
