SE-MKII Tube Preamplifier


The SE-MKII preamplifier embodies Navison audio's latest advances in line-stage preamplifier technology. It is the successor to the SE-MKI preamplifier that has been widely acclaimed by music lovers worldwide since its introduction in 2005.

The SE-MKII Preamplifier is a vacuum tube, line-stage preamplifier that looks as good as it sounds. It is also notable for convenience and ease of use. The unit features input selection and level adjustment by microprocessor-controlled relays. Level and balance can be adjusted in 100 steps of approximately 0.7 dB per step. All functions can be controlled by the hand-held wireless remote control.

Considerable care and attention have been paid to the physical aspects of the design as well. Microprocessor controlled relays, used for selecting sources and level setting, are located right at the input connectors, keeping signal paths short to minimize crosstalk between channels and inputs.
