Features:
- ABACUS power transconductance amplifier:
– No post-pulse oscillations of membrane
– Damping factor virtually infinitely high
– Precise bass
– Loudspeaker properties are idealized
– driving low impedance (<2Ohm) without any problems
- Stereo/Mono switchable
- Line-input via Neutrik high end RCA
- Balanced Input via Neutrik combinded XLR/TRS
- High precision instrumentation amplifier in input stage
- High precision operational amplifiers in the signal path
- low number of amplifier stages and capacitors in the signal path
- Works as linear integrated amplifier
- ALPS precision-potentiometer
- Double binding posts allow bi-wiring down to the PCB
- Microcontroller for:
– Protection circuit protecting loudspeaker and amplifier
– DC-offset-protection
– Overheat protection
– Automatic switch on
– Softstart
– Suppression of noise at power switch-on
- 500VA toroidal transformer
- Seperate supply of digital part, input stage and power amp
- Suplly of the power amps with 3rd order filter each
- seperate capacitor banks for each channel, each 2×40.000µF, 160.000µF in total
- Stable aluminum chassis
- Comes with power cord and user manual
