Description
The Audio-Technica CP8201 microphone impedance matching
transformer is designed to connect a low-impedance balanced or
unbalanced microphone to a high-impedance electronic input. The highquality transformer solves the problem of excessive high-frequency loss
and hum pickup. Locate the transformer close to the amplier: no more
than 4.6 m (15') of cable should separate them. Unlimited cable lengths
can be used between the transformer and the microphone. Encased in
rugged steel for maximum durability and optimum shielding from hum,
the transformer features an XLRF-type connector for the microphone
input and a standard 1/4" connector for the output.
Architect’s and Engineer’s Specications
The microphone impedance matching transformer shall allow a lowimpedance microphone to connect to a high-impedance audio input
circuit. It shall incorporate a shielded transformer designed to work
with balanced or unbalanced microphones. The input connection shall
be through a standard XLRF-type 3-pin connector with locking tab.
Output shall be a standard 1/4" plug. Input impedance shall be 250 ohms
(nominal) and the output impedance shall be 50,000 ohms (nominal).
The transformer shall have a frequency response of 20-20,000 Hz.
The Audio-Technica CP8201 is specied.
