REMOTE-POWERED CARDIOID CONDENSER
QUICK-MOUNT GOOSENECK MICROPHONE
Descript ion
The PRO49Q is a wide-range condenser microphone with a cardioid (unidirectional) polar pattern. It was designed for high-quality sound reinforcement and other demanding sound pickup situations.
The PRO49Q features an XLRM-type connector insert at its base, allowing it to be plugged directly into an XLRF-type jack or cable connector. The unit’s integral 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 offer a very smooth and quiet operation. The microphone element is enclosed in a rugged housing with a low- reflectance black finish.
Operation and Maintenance
Output is low impedance balanced. The output connector mates with XLRF-type connectors. The balanced signal appears across Pins 2 and 3, while the ground (shield) connection is pin 1. Output is phased so that positive acoustic pressure produces positive voltage at Pin 2 in accordance 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 PRO49Q ensures useful output and is an excellent match to the most mixer, tape recorder, and amplifier inputs. It will provide undistorted output even in sound fields as loud as 134 dB SPL. However, due to the high sensitivity, in some instances, it may be possible 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 result in gradual and permanent eduction 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.
