Description
Battery-powered, Dual-Chassis & Dual-Mono Preamplifier
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 allows 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.
FEATURES
- Battery-powered, Dual-Chassis & Dual-Mono configuration
- Both channels, supply units, and non-audio circuits are physically separated, shielded, and electrically isolated
