IWISTAO High-gain Vinyl Balanced Output Phono Preamplifier MM Moving Magnet MC Moving Coil Volume Control Class A Circuit

 
 

Model No: WMMC-PA30

 
This unit is designed with high gain, its gain is twice that of conventional phono preamp, which adopts split casing structure, has independent power supply chassis, includes electronic filter and voltage regulator circuit. Its output circuit of main phono preamp part includes balanced (XLR, True balance) output, with single-ended output, can be connected to single-ended and balanced input power amplifier equipment, in addition, it also includes a volume controller to easily adjust the loudness.
 
 

Features

1. Choose fully discrete components to construct the circuit, which is convenient for fine adjustment of various data parameters.
2. There are two built-in phono amplifier circuits, MM and MC, which can adapt to most users' vinyl record players on the market.
3. The main amplifier circuit selects field effect transistors, which is convenient to reduce the sensitivity of the components to temperature changes and improve the distortion.
4. Choose pure class A circuit to form the amplifier circuit, effectively reduce the harmonic distortion and improve the sound effect
5. The phono equalization circuit does not use the feedback circuit of the conventional integrated IC circuit, but chooses the attenuation type, whichever is the characteristic of its natural sound.
 
 
It is produced in small batches, so the logo fonts are filled in by hand. If you are not used to or do not like this type of marking, please do not buy it.

Learn more about stage amplifier

 

Phono stage amplifier is designed for a phono signal amplification while using Turntables amplifier inside for special sound equalization circuit (RIAA) for restoring vinyl, it cannot be used for other purposes.

 

Method for checking noise sources

After phono player connected with the phono amplifier stage, if there is a significant low-frequency noise, you need to check in which part of the noise. First unplug the phono amplifier input signal cable to disconnect connection between them, if the low-frequency noise disappeared or significantly reduced, that may explain the noise from the phono player; obvious if the same or reduce low frequency noise , the noise it is very likely to put itself caused by phono amplifier.

It may cause a greater frequency noise that no specialized non-standard phono ground wire.

Generally, nonstandard phonograph is a turntable part of music center to cope with this set of sound designed, when external phono amplifier put to ground that could cause a large hum due to the different ground ways.
