High bias current single triode pure Class-A output

Fully differential transistor input stage circuit design

The main amplifier consists of four independent fully balanced amplification units. Each channel has two amplification units working together

Features 3 pairs of RCA and 3 pairs of XLR inputs, with the ability to independently set level attenuation and compensation for each input

Features 1 pair of RCA outputs and 2 pairs of XLR outputs, capable of output simultaneously or separately

Voltage-divider volume control

Two customized high-power square copper wire toroidal transformers
