The Musical Technology C-2 Line Preamplifier, like the C-1, operates as two completely independent line preamplifiers to achieve absolute channel separation. The result is more precise imaging, better focus, and enhanced soundstaging.

No transistor or FET is used in the audio circuit. Extended bandwidth, high intrinsic linearity, low distortion, and low output impedance have been achieved in a ZERO FEEDBACK CIRCUIT. Power supply regulation in the C-2 is effective within a 10% variation of the voltage at the AC mains without serious sonic degradation. Filament supply circuits and plate voltage are highly regulated in order to minimize noise.

Truth to the source and sonic purity have been the goals of this design from the outset. Tape monitor switching and balance control operation have been eliminated and there is only one decoupling capacitor in the entire signal path. Separate record and input selector functions allow the user to record any source while listening to any other. Dangerous “on and off” switching transients have been avoided by the use of a muting circuit. Low output impedance and high output capability (35 V RMS) combine to make the C-2 compatible with all power amplifiers or electronic crossovers and allows the use of very long, even highly capacitive, interconnects.

To realize the full potential of this design the C-2 uses the very best components available for each application. Resistors, capacitors, vacuum tubes, and controls have been selected on the basis of sonic quality and reliability. The chassis exterior is brushed anodized aluminium.

Countless hours of auditioning by a team of musicians and skilled listeners have helped the designers deliver a very relaxed, natural presentation of music. The result of all these efforts is an expression of timeless value offering musical qualities that combine the natural sound of a vacuum tube preamplifier with the authority, speed, and detail of solid state.
