Model no: BA-8001

70Wrms x 4 (140Wx2 ) single-ended 4 channel (Bi-amp) hybrid power amplifier

This is our 8000 series of single-ended hybrid power amplifier, total 4 channels built in one single chassis, compact and flexible, can use over 10 different type of signal tube or power tubes to fine tune the tonal quality, this unit built with no compromise in construction cost, the following is the special features:

Dual meter for level monitoring with high and low meter sensitivity settings

Ultra heavy duty banana binding post

Oil coupling capacitors.

Separate tube and solid-state sections power supply

Over temp and over current and DC offset protections

Switchable Tube / no Tube confgurations

All point-to-point hand-wired for tube sections

Separate input level control for Leftmost and Rightmost sections (Hi and Lo sections of bi-amp speaker), this is very vital for bi-amp configurations in order to get the exact tonal balance

No output transformers , so maximum damping factor and most widest bandwidth can be achieved, the bass control and richness is so good that exceeds any others hybrid amp designs while the mid and high range sweetness and silkiness still holds and sound totally like a pure tube amplifier

Switchable 4 channel or 2 channel Bi-amp mode, XLR input for 140W x 2 configurations
