The Josephson C706 is a pressure-gradient large-diaphragm cardioid condenser studio microphone that delivers low-noise performance, high headroom, transformerless balanced output, low output impedance and a full 20 to 20,000 Hz bandwidth for demanding professional vocal, instrument and ensemble recording. Design and Construction Josephson Engineering builds the C706 around a case-hardened steel body rather than the traditional plated brass shell found on earlier Series Seven models, reducing cost while increasing durability for studio and stage use. The hardened black finish resists wear, and the housing incorporates a distinctive offset grille support structure that controls internal reflections and prevents the brittle, harsh character that many large-diaphragm microphones exhibit. The entire capsule assembly sits on an internal shockmount, allowing the microphone to mount directly to a stand via its yoke without needing an external suspension, which improves mechanical stability and reduces handling noise. Josephson replaces the older permanently attached cable with a standard 3-pin XLR connector on the microphone body, simplifying maintenance and studio integration. Capsule and Electronics The C706 uses a variant of Josephson’s large dual-diaphragm cardioid capsule with 5-micron gold-metallised diaphragms and precision-machined internal surfaces, producing a smooth extended top end, detailed midrange and a controlled proximity effect that remains predictable at close distances. Josephson pairs this capsule with the same discrete FET cascode input circuit found in the flagship C716, ensuring fast transient response, low distortion and stable performance across a wide dynamic range. An active balanced transformerless output stage drives long cable runs without signal loss, while maintaining transparency and consistency compared with classic transformer-coupled designs. Acoustic Performance The microphone exhibits a true cardioid pressure-gradient pattern that rejects rearward sound effectively while retaining natural off-axis response. Sensitivity sits at 26 mV per Pascal, allowing the C706 to capture subtle detail without excessive preamp gain. The equivalent noise level stays below 15 dB SPL A-weighted, keeping self-noise comfortably beneath most programme material. The microphone withstands sound pressure levels up to 130 dB SPL before overload, making it suitable for loud sources such as brass, guitar cabinets and percussion as well as delicate vocals and acoustic instruments. Compatibility and Power The C706 operates from standard P48 phantom power at 6 mA, integrating easily with professional preamps, interfaces and consoles. Its low output impedance ensures reliable performance with a wide range of input stages, from vintage-style preamps to modern ultra-clean designs. The balanced transformerless output preserves clarity while preventing the low-frequency saturation and colouration associated with transformer coupling. Practical Dimensions and Handling Josephson designs the microphone with a 63 mm body diameter, expanding to 100 mm across the yoke, and a length of 261 mm, providing a familiar large-diaphragm profile that positions easily in front of singers and instruments. The 1.2 kg weight reflects the robust steel construction, yet the internal shockmount and yoke system keep placement secure and stable during sessions. Why Choose the Josephson C706 Delivers clear, detailed vocals without brittle high frequencies Handles very loud sources while remaining quiet on soft material Works reliably with almost any professional preamp Resists studio wear and touring use Reduces stand-borne vibration without an external shockmount
