The VT-MCTL is a Head AMP for MC Cartridge to voltage amplification.
\nWe named this VT-MCTL \u201cMC Trance Less\u201d
\nAs the name suggests, it boosts and amplifies the MC Cartridge signal as it is, without using MC Cartridge Trance.
\nCompare to MM Cartridge, MC Cartridge feature that combines excellent reproduced sound with the clear and high resolution, suitably localize the musical instruments. It also has capability to capture fine sound signal of record disk.
\nOn the other hand its output voltage is small as 0.5mv. less 20dB\uff5e30dB output voltage than MM Cartridge .
\nTo make this low voltage boosts as MM level, it need MC Head AMP or MC Trance.
\nBecause of the band limiting of coil inductance, to manage whole sound region ranging by MC Trance is difficult to reproduce the all frequency range of the sound without considering coil component\u2019s core material, core volume, coil wire thickness, coil coating material, number of turns of the coil wire, transformer padding .
\nThat makes critical writers employed by publisher may criticize about the quality of the individual MC Trance and different styles of music sound ,like delicate chamber music, orchestral music and jazz vocal.
\nInstead of MC Trance which only to boost, MC Head AMP has no variations in a frequency characteristic and is capable of whole band amplifies and boost all audio recorded sound.
\nIt has a disadvantage of a power and noise of the amplification circuit, so to solve this problem is very important key.<\/p>\n

VT-MCTL amplifier is a discrete circuit with Non Negative Feedback AMP.<\/p>\n

An initial stage Push-pull Circuit uses FET(Field-Effect Transistor). it exactly boosts feeble signal of MC Cartridge.
\nA rear stage Push-pull Circuit and Emitter follower circuit output signals make high impedance and all signals from MC Cartridge flatly boost whole sound.<\/p>\n

Another feature of VT-MCTL is power supply circuit, it\u2019s equipped with lead shield battery makes lower noise power environment.<\/p>\n

Microcomputer controls battery to prevent overcharge and discharge without requiring troublesome control by human<\/p>\n

Battery supply power is using 18V AC adapter<\/p>\n

At the front panel LED, you will see the battery life and status indicator<\/p>\n

When the batteries are weak, the battery low indicator LED will stay RED. While charging, the charging indicator will orange. When batteries are fully charged, the charging indicator will stay GREEN.<\/p>\n

To switch input impedance which capable cartridge is select from the front panel rotary switches.<\/p>\n

If you don\u2019t get the MC Cartridge impedance, try 47k\u03a9
\nThen turn the dial to the left until sound pressure became half of it.
\nThis is one of the ways to find impedance but you may select reproducing sound by your favorite choice.<\/p>\n
