A-2.1 3 channel stereo amplifier + mono subwoofer power amplifier

with active cross-over network

€ 149.-

 This compact analog technical, well designed amplifier offers flexible adjustments and excellent 

sound quality with a maximum of  2 x 40 Watt  (4-8 ohm) + 1 x 90 Watt (2-8 Ohm), better than many standard size amplifiers.

Finally superb music for desk top compact systems.

The A-2.1 offers superior and more sophisticated technology then most standard equipment. A high quality analog power supply with a shielded transformer provides not only sufficient power for the stereo amplifier, but also has ample reserve to drive the powerful subwoofer channel. All three power output stages are of digital design to ensure that the equipment case never gets hot, only warm to the touch.
The active cross-over network has variable adjustments for all room configurations and different speakers, obtaining excellent sound from even average quality speakers.
For those who build their own speakers, they no longer need to design and build their own passive cross-over networks for the bass and midrange when using the A-2.1 amplifier. Only when employing 2 way satellite speakers a high pass filter is required. Existing passive speakers will benefit by the removal or bypassing poor quality frequency networks.
