SR 314

Description

The Earthworks SR314 Handheld Vocal Microphone utilizes a pre­polarized condenser element coupled to a dedicated wideband

transformerless preamplier that requires 24-48V Phantom Power.
The SR314 features an exceptionally at 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

preamplier 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 rst applied. Allow up to one minute for the microphone to

settle before un-muting.

Care of Microphone

The Earthworks SR314 is a precision instrument crafted to provide
years of top performance and reliability. Following these simple
guidelines will help to protect your investment in the SR314:

Polar Response (typical)

• Never attempt to disassemble the lower half of the
microphone – it cannot be opened.

Frequency Response (typical)

• Avoid extreme heat, condensing humidity and dust

• Rough handling may damage the microphone
even if no visible marks are left.

• When not in use keep the SR314 in its protective
fabric bag.

• The stainless dual windscreen can be removed if it
requires cleaning. See detail on pages 2 & 3.

Cleaning the SR314

All cleaning should be done with either alcohol wipes, or with
a small amount of alcohol on a soft cloth. Make sure any cleaned
elements are completely dry before reassembling.

a. First unscrew the top half of the microphone (the basket)
see “a” below.

b. Cleaning the External Stainless Screen - unscrew the
external stainless screen as shown in image “b” below.

c. Cleaning the Dual Stainless Pop Filter - both sides can be
cleaned, but most of the dirt will be on the side facing the
external screen (see “c” below).

d. Internal Stainless Windscreen - it would be extremely rare
if the internal windscreen should ever need cleaning, but it
may be cleaned if the need arises. As this windscreen is
very close to the microphone element, be extra careful that
the windscreen is dry before reassembly (see “d” below).

b. Clean external
stainless screen

Do Not attempt to
disassemble the
microphone section,

c. Clean dual
stainless pop

lter if necessary

as it cannot be
opened
