Dual-Mono Control Amplifier

Line &
Power Block

Taking rest, while the preamplifier is overtaking control of every detail needed, is the only thing you have to do. The Line Block is adding the desired level and settings to the signal while the electricity needed is conveyed by the Power Block that runs on batteries and allow you to enjoy the ultimate sound quality for at least 15 hours. After that the recharge mode is set automatically and the Power Block works as an energy reservoir. So you can stay hungry for the sound while your power amplifiers are being fed. Moreover, the Line Block also guards the temperature of the Mono Blocks through the communication channel.* And you? You can still continue on listening to your favorite records on and on.
