The Charter Oak SA538 is an affordable, high quality alternative to other condenser microphones in its class.
The Charter Oak SA538's sonic integrity, extreme durability, overall design simplicity, and serviceability make it an attractive option to any of the condenser microphones of its type currently available.
The CharterOak SA538 is a dual diaphragm vacuum tube condenser microphone. Nine (9) pick up patterns are switchable. It is delivered in a locking flight case, power supply, shock mount, and appropriate cables. The parts of the CharterOak SA538 are machined from solid brass and high quality electronic components are used throughout.
The process of creating these microphones involves a seven (7) day burn in of the vacuum tube and no less than 1/2 hour spent with each microphone in a studio environment. Careful listening tests employ high quality microphone preamplifiers and high resolution monitoring systems. Quality checks on every component of each kit complete the process.
It is only after this exhaustive finishing and quality control process is complete, that an SA538 will be cleared for sale to the customer. From the research and development to the delivery of every SA538, it is this attention to detail that makes the SA538 truly unique in its class.
