Cayin MT-45MK3 Vacuum Tube Amplifier KT88*4 Class AB1 Dual Power Amplifier Bluetooth

Bi-amp mode/one-button switching

Equipped with two power amplifier modes: triode and super linear. Triode amplifier mode, the sound is soft and smooth, suitable for enjoying vocals and strings. Super linear power amplifier mode, the sound is open and the sound field is wider, suitable for enjoying large-scale and dynamic types of music. Amplifier, two tones.

The shell of the MT-45MK3 is carefully crafted with 14 spray paint and polishing processes. The front uses an aviation aluminum alloy panel and is equipped with a double-head design, which is both beautiful and practical.

Double meter design, retro and eye-catching, a professional power meter that rhythms with the power, the speed is strong and weak, and you can feel the beauty of the music rhythm.

Cayin MT-45MK3 Vacuum Tube Amplifier KT88*4 Class AB1 Dual Power Amplifier Bluetooth

 

Fully self-developed high-quality toroidal transformer

It is designed with high-purity copper enameled wire winding, which produces lower magnetic noise than standard transformers. Coupled with the special research on shielding packaging technology and circuit protection measures, the power amplifier circuit is further protected from noise interference, and the service life of the product is effectively improved.

1: Power switch (POWER)

2: Volume control knob (VOLUME)

3: Power level meter (left meter and BIAS bias meter)

4: 6.35mm headphone jack (PHONES)

5: Input selection knob ( SELECTOR )

6:BT indicator

7: Meter mode selection power mode/bias mode (METER-POW/BIAS)*

8: Power amplifier mode selection transistor/super linear (TR/UL)

9: Vacuum tube bias adjustment (BIAS SEL/ADJ) (only used when replacing or debugging)

 

*When it is necessary to replace and debug the vacuum tube, switch the METER switch on the upper panel to BIAS, that is, switch the left meter to BIAS bias meter mode. The state of the four power tubes can be tested by this bias meter. In normal use, keep the METER switch pointing to POW.
