Omnidirectional Condenser Microphone

The TC25 is an omnidirectional condenser microphone in a traditional measurement-mic form factor.

The capsule is a 6mm electret condenser device with relatively high self-noise of 27 dBA. Its high-frequency response is rated at 25,000 Hz, which is the primary distinguishing feature between the TC25 and TC30 (30kHz).

Like all the Earthworks TC and QTC omni’s, the TC25 boasts a consistent omnidirectional pickup pattern, low handling noise, and fast impulse response.

This mic was initially designed for percussion applications, including drum overheads. It is available singly, in matched pairs, or bundled with an SR25 as the DK25/R “recording” drum-kit mic set.

The mic requires 48V phantom power, but draws a relatively high current at 10mA, potentially causing problems for budget mic pre’s.

MIX, 2005

There’s certainly no harm in positioning the TC25 omni pair in X/Y stereo, but I had far better results with the TC25s … pointing straight down, one between the snare and hi-hat and the other between the floor tom and kick drum, both five feet high. This placement yielded extremely realistic reproduction with an incredible sense of being in the room with the drums and great LF extension on the floor tom.

SoundOnSound, 2005

Rigged as conventional spaced[-pair] mics above an average jazz-oriented drum kit, they delivered a pleasing, natural, and spacious sound, with lots of subtle transient detail and finesse. Of course, such a minimalist miking arrangement really works best within a good-sounding room, but even when the mics were placed low over the kit in a particularly dead room the detail and resolution of the kit was excellent, and a little reverb ambience was all that was needed to produce a well-balanced and natural sound.

The Earthworks Audio TC25 is also known as: TC-25.
