Valve capacitor microphone with a cardioid polar-pattern.

  • Legendary Georg Neumann M7 PVC capsule
  • EF86 valve

Featuring the classic M7 pressure gradient transducer with dual large diameter sputtered gold PVC diaphragms.  The capsules are specially selected for optimum polar response. Direction of maximum sensitivity is perpendicular to the microphone’s axis, i.e.side addressed. This low noise valve (vacuum tube) microphone has high sensitivity and a remarkable dynamic range, it has the typical full-bodied sound of valve microphones that are loved by vocalists and soloists.  The valve pre-amplifier, selected for its sonic characteristics, is a well established design using a pentode working as a high µ triode.

The M 92.1 S is renowned for its high sensitivity and excellent signal-to-noise ratio.  It has the typical warm, full-bodied sound of tube microphones that are preferred by vocalists and soloists.The M 92.1 S valve (vacuum tube) condenser microphone is suited for difficult radio play recordings as well as a supporting microphone for orchestral recordings.  The renowned pressure-gradient transducer of the M 92.1 S uses two large diameter gold-plated plastic diaphragms.  The valve (vacuum tube) pre-amplifier is equipped with a pentode working as a triode selected for its sonic characteristics.

The N 920.1 power supply provides the operating voltage for the capacitor microphone. It can be powered from AC mains with a primary voltage of 115 or 230 volts / 50 or 60 Hz. For cable lengths over 50 meters it is recommended to have your service provider set the heater voltage of the power supply to 5.8 volts. The N 920.1 is equipped with an on/off-switch, a 7-pin Tuchel connector that powers the microphone and a 3-pin XLR connector with integrated line voltage selector.

The M 92.1 S is packed in a wooden case and comes with power supply N 920.1, connection cable C 92.1 and EA 92 elastic suspension.

Finish: satin nickel or matt black.
