BAT VK80I INTEGRATED AMPLIFIER UNVEILED
Wilmington, Delaware, based Balanced Audio Technology (BAT) has released their all-tube integrated amp the BAT VK80i Integrated Amplifier
Distributor Karma-AV is bringing the BAT VK80i to the UK. Incorporating technological advances first introduced by the brand’s flagship REX series, the long-awaited BAT VK80i all-tube integrated amplifier features specifically the triode-balanced architecture, fuse-less protection and automatic-bias circuits deployed by the REX 3 power amplifier design.
BAT VK80I INTEGRATED AMPLIFIER
Generating 55 watts per channel, the BAT VK80i uses the triode 6C33C-B tube, which offers many times the current delivery of the 6550/KT90 tetrode tube variant often used in tube integrated amplifiers. Arranged in a fully balanced topology, the 6C33C-B allows the VK80i to deliver the high-current performance required to drive even difficult low-impedance speaker loads.
‘FUSE-LESS’ DESIGN
The elimination of internal channel and tube fuses means that the BAT VK80i’s performance is not compromised by the “sound” or the quality of the fuse that is normally placed in the signal path of an amplifier channel. In the rare event of an output tube becoming over-stressed, BAT says that normal operation is restored by turning the VK80i off and on again.
INTELLIGENT AUTO-BIAS OPERATION
Advanced engineering within the BAT VK80i eliminates the need to set and readjust the bias of the output tubes. The VK80i features an intelligent automatic bias design that intuitively adjusts for changing line voltage and ageing tubes, with each output tube having its own dedicated bias circuit.
