Preamplifiers At the heart of the Hi-Fi system based on separate components, the preamplifier connects the devices to each other; all sources (CD player, network, radio or Blu-Ray) connect to it. It also transmits the signal to the amplification system to which it is connected. The preamplifier, which is used with an amplifier or active loudspeakers (which integrates an amplifier), is used to select the source to play and adjust the volume to the desired level. A separate preamplifier allows you to use the amplifier of your choice in the Hi-Fi system. Our preamplifiers stand out for their exceptionally quiet operation – no background noise – that delivers outstanding listening quality.
