Download Brochure

A phono amplifier consequently developed for MC cartridges with a balanced current injection input that optimally implements the tonal qualities of an MC cartridge and does not require load adjustment.

The Technology in Keywords:

• Balanced “Current injection (CI)” input
• ULN technology delivers lowest noise at the record level!

• Base circuit as the most broad-band basic circuit
• Gain adjustment via the generator current
• Feedback-free circuit with a short signal path
• Consequently balanced circuit
• Balanced single-ended Class-A LEF output
• Frequency response with a maximum of +- 0.1 dB deviation from the ideal
• Channel balance with a maximum of 0.05 db

Equalization and Setting Options

• Four different gains
• Neumann constant (optionally classic RIAA)
• Subsonic filter switchable
• Optional RIAA adjustments in the deep bass and low mid-range in the current-to-voltage converter
• Extremely low-loss passive equalization

The Highest Quality Components and Build Quality:
• Special low-noise transistors with a high Hfe, each 10 in parallel
• “Balanced Current” capacitors for precision and timbres
• Induction-free polystyrene capacitors
• Metal film resistors with 0.5% tolerance
• Gold plated 4-layer printed circuit board
• Copper plated iron shield-cover over the core module, with mechanical damping.
• Strongly resonance damped, massive housing.

• Extremely clean power supply

A New Standard

Progress should not be stopped by traditional standards. For example, asymmetrical phono input and structure is no longer up to date.

A new chapter of phono reproduction has been opened with the use of the MC-cartridge current by the CI technology. Most modern MC-cartridges are now efficient and provide a low inner resistance. For such modern MC-cartridges at the CI input, the term “dynamic cartridge” gets a completely new meaning – a meaning that can be experienced with the MCCI Signature ULN.
