Josephson C725

The Josephson C725 is a variable pattern hybrid tube microphone perfect for vocals and voice overs. This microphone features a very high Max SPL of 165 and it's 20 Hz to 20 kHz means this microphone will give you a crystal clear and accurate representation of the audio you want to capture.

The head grille uses Josephson’s patented aluminium foam, fused to the housing for physical and electrical protection, with only an ultra-fine highly open mesh for contamination protection. No other structure is needed, so internal reflections are random and minimal, allowing clean, detailed sound pickup. The capsule assembly is internally shock-mounted so the microphone can be attached directly to a stand through its yoke mount. The C725 features a satin nickel finish for durability in studio use.

The internal circuitry is related to other Josephson mics, with a cascode topology for best linearity. Instead of using two FETs to form the cascode, in the C725 the voltage gain section uses a low-noise FET, while the current gain stage uses a readily available current production pentode vacuum tube. This provides the low noise of the FET along with the dynamic characteristics of the vacuum tube. The output is provided through a custom nickel-core transformer, which has independent windings for output and gain control.
