Multi-Pattern Tube Condenser Microphone
The TCM1050 is a rebadged Alctron HSGT-2B, a multipattern, large-diaphragm tube condenser microphone.
The capsule is a 25mm dual-diaphragm design that provides 9 pickup patterns via a switch on the power supply. The gold-sputtered diaphragm measures 3 microns in thickness.
The specs claim “Tube preamplifier circuitry with 6072 vacuum tube (a classic 12AT7 specially selected for low distortion, superior signal-to-noise ratio and minimum sensitivity to mechanical vibrations)”, but in most cases the tube is a 12AX7, which has performance characteristics inappropriate for the circuit. A common mod is to replace this tube with a true 12AY7/6072 type.
The capsule and circuitry of the TCM-1050 are believed to be identical to the TCM-1150, and therefore the mods common to the TCM1150/Apex 460 are applicable for this mic as well.
The mic ships with a power supply and cord, the SSM-1050 spider shockmount, 7-pin cable, FW-1050 foam windscreen, TMCC-1 aluminum case, user guide, and warranty card.
