Model: HTT-978 professional speech amplifier
Professional amplifier are used to improve the sound quality of microphones and improve the quality of recording. It has always been an artifact used in professional recording studios. It is compared with ordinary karaoke mic, professional grade with 48V power supply, with output port, the music selection is professional and thick and round, which can improve the normal microphone's sound quality, and improve the sound quality to a higher grade.
The pre-amplification part of this amplifier refers to the main propaganda phone amplifier of Neve which price is more than 3000usd.The sound quality is similar as the marcket's 450-650usd amplifier, It is characterized by large gain, wide range, strong target, transparent and clear mid and high frequency.
The spare parts with transformer sell usd89.99 are spare parts without welding, excluding the shell [no humming when running naked.
The USD89.99 parts contain the shell, and you need to be alone
USD109.99 is a finished product, all of which are ready, and can be used directly after receipt.
Same industry or enthusiasts are welcome to buy. The op amp chip model and the two transistor models have been polished, to avoid the board be copied. Hope understand.
The comparison recording with TB12 mics is as follows:

The function and feature:
Many people think that a microphone amplifier is a kind of professional equipment that amplifies the sound of a microphone.In fact, this is not the main function of the microphone amplifier. The main function of the microphone amplifier is used to modify and improve the sound transmitted from the microphone, to make the sound more beautiful. A good amplifier will makes the low frequency more powerful and cohesive, and can make the original high frequency sharp sound becomes soft, harmonious and sweet, and the middle frequency becomes rounded; the amplifier can make some microphones that are not resistant to sound pressure become more resistant to loud sound pressure.
Amplifier is a good tool to add luster to the sound of the microphone, and it is an indispensable protagonist in a professional recording studio. Conversely, a poor speaker amplifier will amplify the volume, but it will make the original normal high-pitched sound sharp, and the sound will lose its texture, which is worse than the broken sound with a coarse tone.
Therefore, it is very necessary to have a good speech amplifier in professional recording.
The importance of the amplifier is no less than that of the microphone and the sound card. If a microphone is worth 3000usd to 20000usd, then a good speaker amplifier also has this value.
The importance of the microphone is same as amplifier.
Function and performance introduction:
Big three-core balanced input: provide two balanced inputs, XLR big three-core input and 6.5 balanced input, support dynamic microphone, use balanced line.
Output: Provide one XLR large three-core balanced output, one 3.5 unbalanced output, the 3.5 interface can be connected to the headphone output to test, and can be output used by other equipment too.
48V power adapter: can directly supply power to professional condenser microphones that require 48V power.
-20DB attenuation switch: it can be used when a loud pressure instrument is recording, or when the sensitivity of the condenser microphone is relatively large, this switch can be used.
Phase switch: the signal waveform phase can be reversed, so that the timbre can be changed, and at the same time, some tooth sound details will be reduced
High cut: The condenser microphone with more high frequency can be cut off, so as to reduce the frequency response above 4KHZ.
Power consumption: 2W
