ARCHITECTS AND ENGINEERS SPECIFICATIONS:
The microphone shall be of the pre-polarized condenser type with a modular threaded capsule
available in a cardioid pattern. The microphone shall operate on 5 Volts via USB connection
and the nominal output impedance shall be equal to 1000 Ohms at 1 kHz. The microphone
shall have a sensitivity of 1.3 mV / Pa. The microphone shall have a maximum SPL level of
115 dB and the microphone shall have a base with a membrane on-off switch with built in
options of push to talk, push to talk, and bass roll off filter. The microphone shall consist of
brass parts, aluminum tubing, and coiled steel gooseneck. The dimensions of the microphone
shall be 310 mm in length, 12 mm in diameter at the microphone grill and 90 mm in width at
the base by 99 mm in depth. The microphone shall be the Audix USB12.
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). (For more details please visit our
website www.audixusa.com).
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.
USER TIPS:
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.
