Soundsmith MMP-4 – Phono Pre-amps


Product Description

An upgrade in quality does not have to deplete your wallet…..

The Soundsmith MMP & MCP preamps are revolutionary designs for their price – and the comments we get at each hi-fi show prove it. These preamps are what we use to demo our cartridges at all our shows even our high end cartridge designs –

Each hand – made preamp circuit is housed in a high quality aluminum case, powered by an external DC power supply, with easy to set up instructions. All amplifiers have extremely accurate RIAA equalization response.

Model No. MMP4
Type: moving magnet
Input Load*: 47k 100pF
Gain*: 43dB standard ** or 34dB special order
Noise (unweighted): -92 dB down
Features: high grade low noise components

Optional, for all models we can built 50 ohm output, i.e. for driving long lines. $300 extra

Dimensions for the MMP4, MMP3 and MCP-2 (without the knob, which adds 3/4″ to the height)
7” deep, 1&1/2” high, and 4&1/4” wide.

Overload specs for our preamps: Output clipping into 10K Ohms = 8.3 Volts RMS – all models.

Input overload levels for output clipping or non linearity:

MMP3/MMP4 ~~~ 20Hz – 5.3 mV; 1Khz – 53 mV; 20KHZ – 530 mV;

MCP-2 ~~~~ 20Hz – 1.4 mV; 1Khz – 5.3 mV; 20KHZ – 35 mV with input load set to 200 Ohms;

*standard values, other gain and loading options can be configured on request, $100 extra – select ‘custom made’ option from order form below and be sure to tell us what you’d like!

** Our Moving Iron cartridges are best with 42- 44 dB gain preamps; most moving magnet and moving Iron cartridges will work well with our 43dB gain preamps, however, for VERY HIGH output cartridges (4.5mV or higher) we offer a 34dB gain preamps as an option ~

THD measurements 1kHz, ~0.004%

24 volt power supply included [US standard 120 volt]; optional European (schuko) 230 volt AC to 24 volt DC transformer
