Shengya A-25SE Electronic Tube and Transistor Hybrid Amplifier Bluetooth 5.0 RCA/XLR 180WX2 8Ohm

Feature:
1.First level input amplification:   
Using ECC83 electronic tubes to achieve delicate, sweet, high gain, and low noise,    creating a  classic "tube flavor" sound.

2.Second level voltage amplification:   
Two 6C3 electronic tubes are used for high amplification voltage amplification,  achieving   undistorted output of large dynamic signals.

3.Innovative amplifier driver stage: Two 6N11 electronic tube SEPP buffer amplifiers significantly enhance  the driving effect,      driving the rear stage amplifier with full power.

4.High voltage rectification and stabilization: Using 6Z4 electronic tube rectification and field-effect transistor serv stabilization, laying the foundation for the mellow and beautiful tube taste.

5.One machine includes multiple interfaces to adapt to multiple audio sources
Equipped with fiber optic, coaxial, ARC digital signal input interfaces, one set of analog signal RCA and XLR input ports, suitable for TV CD、 Black glue machine, game console and other equipment; Bluetooth wireless transmission allows for instant connection to mobile phones, tablets, and laptops, providing more freedom in wireless playback.

6.35 years of craftsmanship accumulation
Specializing in the research of gallstones mixing technology

7.Electronic tube preamplifier
12AX7 (ECC83), 6C3 electron tube for two-stage common cathode amplification, 6N11 (E88CC) electron tube for SEPP buffer amplification.
Transistor power amplifier
Eight Toshiba high-power transistors form the OdB current amplification output stage circuit.

Multiple tuning functions:
Creating an Ideal Sound Experience
GAIN (gain control function)
1. Enhance the push effect to match low sensitivity speakers;
2. The sound can be adjusted to be soft or tightLOUD (equal loudness function)
After startup, it can enhance the bass performance at low volume, allowing users to experience a delicate and surging feeling even at low volume.TONE (Tone Adjustment Function)
Direct/Tone Dual Mode: One click Switch between "Original" or "Personalized Tuning"
After turning on the TONE switch, BASS adjusts the bass; TREBLE regulates tweets
