The PRO 51Q is a wide-range condenser microphone with a cardioid 
(unidirectional) polar pattern. It was designed for high-quality sound 
reinforcementand other demanding sound pickup situations.
The PRO 51Q 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 11V to 52V DC 
phantom power source.
The small-diameter gooseneck is very easy to manipulate for proper 
positioning. It is heavily lubricated to offer very smooth and quiet operation. 
The microphone element is enclosed in a rugged housing with a low-reflec-
tance black finish.

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 (11-52 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 PRO 51Q ensures useful output and an excellent 
match to most mixer, type recorder and amplifier inputs. It will provide 
undistorted output even in sound fields as loud as 135 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 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.

Connect the output terminals of the microphone to a device that has a 
microphone input (balanced input) compatible with a phantom power supply. 
The output connector is an XLRM-type with polarity as shown in the figure 
below.

For product improvement, the product is sublect to modification without notice.
