Miniaturized USB hi-def condenser microphone with clear accurate sound for recording voice and acoustic instruments directly into a computer.

The USB12 is a miniaturized USB condenser microphone used for recording voice and acoustic instruments directly into a computer. Known for its clarity, excellent transient response, SPL handling, and ease of operation, the USB12 is designed to naturally capture and reproduce vocals and instruments with stunning detail.

The USB12, which is characterized with a uniformly controlled cardioid polar pattern, provides excellent isolation and control at the sound source. With a smooth and accurate response over a frequency range of 50 Hz - 16 kHz, the USB12 sits on top of a stable desktop base and can be quickly and easily adjusted to any position.

The USB12 has a 16 bit sample resolution and supports 44.1k and 48k sample rates for both playback and recording. This high definition condenser microphone features a push-to-talk button with the option of ‘steady on’ or ‘momentary on’ as well as a headphone jack for real time monitoring and a bass roll-off filter to control unwanted low frequency signals.

The USB12 includes a 6 ft USB cable, matte black finish, and field replaceable capsule. Also available in white (USB12-W).

Operation

The USB12 is a miniaturized condenser microphone designed to work with a USB port on any computer. The computer must be equipped with USB 2.0 or higher.

Plugging in the microphone: With the supplied cable, plug one end of the cable into the microphone and the other into the USB port on your computer. You will get a message to the effect of “Found New Hardware” and the drivers will load as “C-Media USB Headphone Set.” Depending on the type of computer you have and software, you will want to change the default setting of your audio microphone to the USB12 (C-Media).

Headphone input: By using the headphone input, you can monitor yourself in real time (without latency). You also have the option to use the headphone input or powered speakers.

Switches on underside of the base:

Push to Lock: This means that when you push the membrane switch on the front of the mic, it will turn the mic on and off in a normal fashion.

Push to Talk: This means that the mic is ONLY on when you push and hold the membrane switch. This feature (known as a “cough” switch) is handy to have, for example, in a phone conversation where you would like to control what the person on the other end of the line is hearing. Or if you are conducting or recording an interview, and you want to have a quick way to monitor and edit undesirable sounds or comments.

Bass roll-off: This switch allows you to limit or eliminate low unwanted frequencies (such as air conditioning or electronic hum).

Changing Capsules: The capsule on the USB12 is threaded and interchangeable with 2 other capsules - omni directional and hypercardioid. Capsules may be ordered separately from any authorized Audix dealer.

Speaking distance and angle of microphone: The two flexible portions of the microphone will enable you to position the microphone to any number of angles. For the optimum sound quality, do not speak or play directly into the microphone at a close distance, but rather at a distance of 4-6 inches away.

Windscreen: The supplied windscreen should be used to help minimize pop noise and breath noise. If breath or pop noise appears to be excessive, either move further away from the microphone or try speaking over the top of the microphone rather than directly into it.
