| CharterOak SA538 Tube Condenser |
The CharterOak SA538 is an affordable, high-quality alternative to other condenser microphones in its class. Its 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 high standard of quality and affordability of the CharterOak SA538 have been achieved through an extended period of research and development, including beta testing by a wide variety of end users.
The parts of the CharterOak SA538 are machined from solid brass and high-quality electronic components are used throughout.
The process of creating a CharterOak SA538 Condenser Microphone is started by hand under the strict supervision of CharterOak personnel. Under that supervision, the parts are quality checked and assembled at our facility in Connecticut.
The microphones are finished and the parts are quality checked a second time by experienced engineers. The process involves a seven (7) day burn in of the vacuum tube and no less than ½ 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.
The microphone is delivered with a lifetime warranty on all parts and labour and easy access to factory technical support.
| CharterOak MPA1 Mic Pre Amp |
The MPA-1’s transformerless input circuitry and transformer balanced output give the engineer the best of both worlds. With the input and output gain controls, the engineer can carefully control the signal from ultra clean and transparent, to pleasant coloration added by the MPA-1’s output stage and Cinemag output transformer.
The MPA-1 is also fitted with a constantly variable high pass and low pass filters that encompass the entire bandwidth of the device, a -6dB pad, +48VDC phantom power, and phase reverse, giving the engineer further control of the signal and flexibility.
