Description
The Earthworks SR314 Handheld Vocal Microphone utilizes a pre-
polarized condenser element coupled to a dedicated wideband
transformerless preamplifier that requires 24-48V Phantom Power.
The SR314 features an exceptionally flat 20Hz to 30kHz frequency
response, fast impulse response, low handling noise, a consistent
cardioid polar pattern and high SPL handling capabilities. It provides
excellent uncolored rejection of sounds arriving off-axis and yields
more gain before feedback than conventional vocal microphones. A
mic clip for stand mounting and a protective fabric bag are included
with the microphone.
In Use
Using a standard XLR-3 cable, connect the SR314 to a microphone
preamplifier capable of supplying 24-48V phantom power at 10mA.
It is normal for any phantom powered mic to “pop” when powered
up, so be sure to mute the speakers or headphones when phantom
power is first applied. Allow up to one minute for the microphone to
settle before un-muting.
