CAD Audio E300S

Multi-Pattern Condenser Microphone

The E300S is a revised version of CAD’s E300 microphone. The new version is intended to sound the same as the E300².

The E300S has the same capsule and circuit design as the older version of the microphone. Like the earlier version, it uses a pair of 9V nickel metal hydride batteries to power the circuit; phantom power, when available, is used to recharge the batteries.

The microphone’s behavior is configured via four switches on the front of the body:

• Pad: flat or -20dB
• HPF: flat or -6dB/octave @ 135Hz
• Polar pattern: Cardioid, Omni, or Figure-8
• Power: on/off

The capsule is a large-diaphragm true condenser. The photos we’ve seen show the characteristic backplates of the K67. According to measurements submitted by an E300S owner, the capsule’s outside diameter is 33.6mm; the suspended area of the diaphragm has a diameter of 26.3mm.

According to CAD, the impedance conversion circuitry is linear with respect to frequency response; there is no fixed EQ within the circuitry.

See the E300v2 profile for full specifications.

The mic was released in 2012.
