The SA538B is a condenser microphone that employs two large, ultra-thin, side terminated gold diaphragms and a vacuum tube head amplifier using a selected low noise tube, and output transformer. As a result, the model SA538B has very low inherent noise and broad dynamic range. Its timbre is distinctive. Its rich and balanced sound makes it an ideal choice to ensure extremely high quality sound reproduction.

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 CharterOak S600's rich and particularly non-sibilant eq make it a perfect choice when used as a stereo overhead pair on the drum kit. The result is clean and rich cymbals with lots of sustain while picking up all of the transient peaks of the snare and tom toms. The extended bass frequency response of the S600 makes a single S600 a perfect choice for recording bass guitar and its particularly smooth treble response makes it a perfect choice for recording bright electric guitars. It is hard to imagine a more versatile tool in the studio than a pair of CharterOak S600 vacuum tube condenser microphones.

The CharterOak E700 is a dual diaphragm FET condenser microphone which employs two 1.22" center terminated, gold sputtered, Mylar diaphragms and pure class A head amp electronics. While this microphone is excellent for universal applications, its rich sound, extremely low noise floor, and build quality make it a particularly excellent choice in the broadcast and voice over environments. The E700 offers cardioid, omni and figure-8 pickup patterns and a two-step sensitivity switch.

The CharterOak M900 is the only small diaphragm condenser microphone in the CharterOak line of high quality microphones for recording and broadcast. After an extended period of development, CharterOak has met the challenge of creating a small diaphragm condenser with a reasonably flat frequency response, and the robust and musical sound for which all CharterOak microphones are known. The M900 achieves all of these goals and more, as it features a two-step sensitivity switch (-10dB and -20dB) and a two position bass roll off at 150Hz (3dB per octave) and at 75 Hz (6dB per octave). Furthermore, each M900 head amplifier is shipped with our S-5 (cardioid), S-6 (hyper-cardioid), and S-7 (omni directional) capsules, all of which enhance the functionality and versatility of the microphone.

The CharterOak M900T small diaphragm condenser microphone is the vacuum tube version of our popular M900. It is excellent in situations where flat frequency response, excellent transient response, and robust and detailed sound are required.

The CharterOak M900T is a small diaphragm condenser microphone, which employs a vacuum tube head amplifier and Cinemag 2480 output transformer. The microphone utilizes modified versions of our S-5 (cardioid), S-6 (hyper-cardioid), and S-7 (omni-directional) capsule types. All three of these capsules are shipped with each M900T head amplifier, and are easily interchangeable. Sequentially numbered matched pairs are available for stereo recording. The M900T is equipped with a 15dB pad facility, and a 6dB per octave bass roll off at 75Hz. It is delivered in a hard locking flight case with a windsock, shock-mount, and custom power supply, and is guaranteed for life.

The CharterOak Small Studio Collection is the total microphone solution for small recording studios with a tight budget and large studios that would like to add the CharterOak sound to their existing microphone collection.

Consisting of the SA538 Large Diaphragm Condenser, the E700 Solid State condenser and a sequentially numbered matched pair of M900s. Start up and well established studios will benefit from this full spectrum selection of microphones and will be able to tackle any recording situation from vocals to orchestra to loud electric guitars.

The SA538, E700, and M900 are highly regarded by musicians, engineers, producers, and pro-audio critics alike, for their exciting sound, consistency, and build quality. This collection is all you need and is delivered in a solid locking flight case with all of the necessary accessories and CharterOak's Lifetime Warranty.

The CharterOak SCL-1 Discrete Compressor Limiter will provide a constant output level regardless of input level or frequency, without the familiar pumping and gasping effect that is inherent in most compressors and limiters.

This can be attributed to the design of the circuit, which combines the features of waveform differentiation and integration. This allows for fast attack times without overcompensation and a release characteristic that is a function of dynamic range and average program level. The device achieves this by employing a rectifier circuit that possesses a parabolic average charge curve. The end result of the circuit is a quick release that releases to a continually changing average level, which is determined by the parabolic charge curve of the storage capacitors.

The CharterOak SCL-1 is designed to fit any standard 19" rack. The unit may be used as a stereo unit, or as two independent limiters in the dual mode. This feature enables the end user to employ the device in one or two track production applications.
