MM/MC Phono Preamplifier
IWISTAO Split-type MM / MC Phono Stage Amplifier Replace Boosting Transformer
Model No: WMMC-PA22
It is a MM / MC Phono Amplifier with split design. Power for the independent upgrade version, the external power supply is 30W Toroidal transformer, also increase of the design of a power supply filter circuit that is not a conventional LC or RC circuit, but chose the transistor electronic filtering, which constitute a two characteristics of the filter circuit together with the phono amplifier, so that the phono amplifier put the output noise in the clutter component to a very small value.
Phono Stage Amplifier
1. Parts selection as much as possible infiltration of some HIFI level elements, and using MKP film capacitors
2. The input signal contact point has the original switch contact switch to sealed relay contacts, less effective signal loss and extend its lifecycle.
3. Use a thick aluminum as the front panel
4. Laser lettering font on the back panel.
5. Compatible with MC phono. Users using the MC moving coil head, usually to choose the boost transfomer to increase the intensity of the output signal, but it is expensive and frequency response is not uniform, it is highly recommended to use this model.
1. RIAA Bandwidth: 20Hz to 20KHz (± 0.25dB)
2. MC input
a) Gain: In the pickup output 0.35mV when, via 1KHz measurement point, when there is an output measured 350mV
b) Input impedance: 200 Ohms
Signal Noise Ratio:> 86dB (unweighted)
a) Gain: In the pickup when the output is 3.5mV via 1KHz measurement point, when there is an output measured 350mV
b) Input Impedance: 47K Ohms
Signal Noise Ratio:> 98dB (unweighted)
4. The size of a single chassis: width 133 high 63 deep 250 (mm)
5. Weight: 2.9kg
Learn more about phono stage amplifier
Phono 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.
