Description
The PRO49QL is a wide-range
condenser microphone with a car-
dioid (unidirectional) polar pattern.
It was designed for high-quality
sound reinforcementand other de-
manding sound pickup situations.
The PRO49QL features an XL-
RM-type connector insert at its
base, allowing it to be plugged
directly into an XLRF-type jack or
cable connector. The unit’s inte-
gral electronics can be powered
from any external 9V to 52V DC
phantom power source.
The small-diameter gooseneck is
very easy to manipulate for proper
positioning. It is heavily lubricated
to oer very smooth and quiet op-
eration. The microphone element
is enclosed in a rugged housing
with a low-reectance black nish.
Operation and Maintenance
Output is low impedance bal-
anced. The output connector
mates with XLRF-type connec-
tors. The balanced signal appears
across Pins 2 and 3, while the
ground (shield) connection is pin
1. Output is phased so that pos-
itive acoustic pressure produces
positive voltage at Pin 2 in accor-
dance with industry convention.
DC phantom power (9-52 volts) must be applied equally to Pins 2 and
3, with the ground for the power supply connected to Pin 1. This can be
provided by a console or mixer with built-in phantom voltage or with the
addition of an in-line phantom power supply.
The high sensitivity of the PRO49QL ensures useful output and an ex-
cellent match to most mixer, type recorder and amplier inputs. It will
provide undistorted output even in sound elds as loud as 134 dB SPL.
However, due to the high sensitivity, in some instances it may be possi-
ble to overload sensitive input stages.
While a modern condenser microphone is not unduly sensitive to the
environment, temperature extremes can be harmful. Exposure to high
temperatures can be result in gradual and permanent reduction of the
output level. Avoid leaving the microphone in the open sun or in areas
where temperatures exceed 43°C for long periods of time. Extremely
high humidity should also be avoided.
