HiFi Rose RA180

Front Panel

  • Overview – Line Input x3, Balance x1, Phono x1, Supports a total of 5 external inputs. Volume is motorised and adjustable remotely.
  • Tone Control – You can control the Treble, Bass and Balance attributes.
  • Active Crossover – By eliminating the low frequency range, it specialised only the high frequency area and outputs it to enable clear treble playback.
  • Main Volume – The main volume is motorised and is adjustable remotely.
  • Pure Direct – The input signal can be bypassed without balance, tone control, and active crossover to increase the purity of the sound quality.
  • Speaker AB Selector – You can connect two speakers, and you can adjust the switch to select the speaker.
  • Power LED Brightness Adjustment Switch – Adjust the brightness on the front of the product in 3 steps.
  • Subsonic Switch – Block the ultra-high frequency to prevent ultra-high noise from negatively affecting the speaker.
  • Sound Reduction Switch – Reduce the amount of volume output to a minimum step.

Rear Panel

  • Overview – A power breaker was adopted to improve the conductivity of the input electricity, and the resolution of the sound quality was improved by securing a wide passage of the input.
  • BTL Mode – Four Mono Amplifiers are combined into two amplifier blocks, each supporting 400W (8 Ohms) output per channel.
  • Power Input Terminal – It adopts FURUTECH terminals milled in pure copper, optimised for audio, and delivers the purity of the input electricity without interfering with it.
  • Subwoofer Output Support – Connect with active subwoofer units to provide a rich bass listening experience.
