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 o󰀨er very smooth and quiet op-

eration. The microphone element

is enclosed in a rugged housing

with a low-reectance 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 amplier 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.
