Mactone X-21
State of the art grade Triode Stereo Phono Equalizer Preamplifier
2 full-sized power transformers with large capacity
X-21 designed for more advanced sound reproduction will satisfy both analog and digital fans. Your power amplifier performance varies much depending on a preamplifier to be used. Thoroughly examined circuit design for better sound is almost perfect requiring no further improvement. The power supply section supporting amplification is built with two transformers using high efficiency orient core, and extraordinarily large capacitance capacitors. Not only these but many other know-how compiled over long years of our experience are contained. Just hook X-21 up with LINE input of either a valve or a transistor system you have. You will be travelling to unknown world of music.
Unlike ordinary easy to design negative feed back type phono equalizer for analog record reproduction, X-21 adopted a CR type circuit technical difficulty of which we have overcome for more natural tone and spreading sound stage. Line circuit assuming amplification of phono equalizer circuit along with a digital equipment has an important role to directly drive a power amplifier. Failure in designing of this section gives fatal outcome to total system. X-21 is capable of transmitting sound energy and enough thickness of mid and low ranges to a power amplifier. X-21 makes the most of elements of valves characterized with high voltage and large current to secure wide bandwidth and big dynamic range despite of its almost non negative feedback circuit resulting in live sound reproduction. Excellent parts and simplified circuit for use over a long time in stable operation.
