Thank you for purchasing this product. Before using the product, read
through the user manual to ensure that you will use the product correctly.
Please keep this manual for future reference.
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.

业录音、电视广播、会议及其他高要求的收音应用。
此电容话筒设计于桌面固定安装应用，使用卡农 XLRM-3 连接头，以其频率
响应为 70Hz 至 16,500Hz 的心形指向收音头收音，内置音频放大供电模组，
工作于外置 11V 至 52V 直流幻象供电，可提供达 135dB 的声压输入电平，
而开通灵敏度电平为 -37.5dB，输出为平衡低阻抗 (100欧姆) 3 针卡农公头。
现在的电容话筒虽然不会对环境过度敏感，但在极高或极低的温度下亦可能
损坏，暴露于高温中可能导致输出电平逐渐及永久性减弱，应避免将话筒留
在日晒的地方或长时间置于温度超过 43°C 的地方，而极高湿度也应避免。
将话筒的输出端子连接到具有兼容幻象电源的话筒输入（平衡输入）的设备。
输出接口是 XLRM 型接口，其极性如下图所示。
