Reference Silver
Tube Microphone
From Manley Labs:
The Manley Reference Silver delivers large-diaphragm tube microphone performance inspired by the acclaimed Sony C-37A, combining an American-made Josephson capsule with all-tube Manley circuitry. Hand-built in California, it provides rich midrange tonality and extended frequency response for vocals, instruments, and ensemble recording. It wins where warmth and dimensional imaging are prioritized over clinical accuracy.
The Reference Silver employs an American-made capsule design reflecting classic C-37A sonic characteristics, delivering rounded midrange presence without sibilance or resonant artifacts. This tonal balance proves effective for female vocals and saxophones, capturing harmonic content and spatial information with cohesion. The controlled high-frequency response makes the microphone equally suitable for drum overhead applications, managing cymbal transients without excessive brightness or harshness.
The Reference Silver provides mechanically switched cardioid and omnidirectional polar patterns via rear-mounted selector on the head basket assembly. This dual-pattern capability enables adaptation between focused, proximity-effect-influenced cardioid response and diffuse omnidirectional capture for room tone and ensemble recording. Pattern selection facilitates matching microphone characteristics to source positioning and acoustic environment requirements across diverse recording scenarios.
