Point to Point Wiring
Know before you buy
Adaptive AutoBias continuously monitors and adjusts the bias of each tube in real time. This eliminates the need for manual adjustments, ensures the amplifier operates at peak performance, and significantly extends the lifespan of your tubes.
Yes, the ProLogue Premium is designed for high flexibility and is compatible with a wide range of power tubes, including EL34, KT88, KT120, and KT150. The auto-bias system automatically detects the tube type and adjusts accordingly, allowing you to tailor the sound signature to your preference.
By using point-to-point wiring instead of printed circuit boards, the signal path is kept as short and direct as possible. This minimizes interference and signal degradation, resulting in improved clarity and a more transparent audio presentation.
The amplifier features a built-in 'Bad Tube' indicator light. If a tube fails, the system will safely put the amplifier into protection mode and illuminate the LED next to the faulty tube, making maintenance straightforward.
Yes, the ProLogue Premium is engineered with custom-wound output transformers and massive toroidal power transformers. This robust power supply provides the current and stability necessary to maintain control and bass authority, even with speakers that present a challenging load.
