Description AOSIBAO M18 Tube Preamp Amplifier Mini Bluetooth Integrated Amplifier Rated 35W For Room Desktop Advantages: - Based on M 18, it supports about 30 kinds of tubes, including 6J2, 6K4, 6N15, 6H15N, 6BC5, EF40, EF95 and 6AG5 - Support PCI expansion interface, which can match different functional modules. Leading functions added - Support NICAM technology - The third generation multi-layer PCB patch circuit Features: - Compact audiophile tube amplifier - PCI expansion interface for more functions. Electronic tubes can be adjusted through switches, so that the power amplifier is suitable for more electronic tubes. NICAM technology makes sound crystal clear - Electron tubes are upgraded to 6N15. The third generation multi-layer PCB patch circuit. Integrated circuit layout optimization - Fit nearly 30 kinds of electronic tubes. A special lifting circuit enhances the effect of tubes. Perform a second optimization on the original basis and launch the V2.0 version, adding a number of technologies. Some chips are polished and encrypted. Suitable for 6J2, 6K4N, 6N15 electronic tubes, etc. - 6J6W for RAYTHEON is recommended to replace 6N15 series. The former's sound is thick and surging, human voice is full, moist and warm, delicate and round. And low-frequency power is sufficient - Audiophile and high fidelity. Tailored for rooms and other small environment - Selected components, including TDA7377 amplifier chip for ST, 4700uf power filter capacitors for NCC, Bluetooth 5.0 chip for JL, high-voltage capacitors for NHC, potentiometer for ALPS, capacitors for ELAX Rubycon, Blue audiophile capacitors and red coupling capacitors for WIMA - Using high-performance 5.0 audiophile Bluetooth decoder chip AC6925A for JL - TDA7377 chip for ST is matched with the tube preamplifier to create rich and sweet sound. TDA7377 is a 4-channel chip, bridged to 2 channels through engineer's technical improvement. The original 4-channel 10W has been increased to 2 channels with 35W maximum power, and the sound quality has also been improved - Small and exquisite. One machine for dual use. Tube preamp can directly output to the power amplifier - Support Bluetooth or audio line input to play. The direct output of preamp tube plays a paramount role in polishing and pre-amplification, rejuvenating ordinary power amplifiers or old power amplifiers. And its sound is sweet and warm, delicate and transparent Performance Parameters: - Output power: 35W - Input impedance: 47KΩ - Input sensitivity: 300mV - Signal to noise ratio: ≥80dB - Total harmonic distortion: ≤0.3% (1KHz) - Frequency response: 25Hz~30KHz±2dB - Dimensions: 9.5 x 9.5 x 5cm/3.7 x 3.7 x 2" (WxDxH) - Weight: >1kg/2.2 lb Package Included: - 1 x Set of Amplifier Note: - It is assembled and ready to use.
