Product Code:514B
Handheld Microphone
|
The Shure 514B is a low
impedance, dynamic, handheld microphone designed for paging and
public address systems. It provides clear, natural voice response
and high intelligibility. |
|
| Features |
The 514B connects to microphone
inputs rated at 19 to 300 ohms. It can be used in applications that
require long cable lengths, or where severe hum conditions are
present. For connection to high impedance inputs, use Shure A95
Series Line Matching Transformers.
The 514B microphone is provided with a four-conductor (two
shielded) coiled cable and a "Million-Cycle" leaf-type switch
designed for constant use under the most rigorous conditions. The
514B fits naturally and comfortably in the hand and is not affected
by heat or humidity. The exclusive ARMO-DUR case resists mechanical
shocks and vibration, and is impervious to oil, fumes, salt spray,
ultraviolet radiation, and corrosion.
514B includes coiled cord, mounting bracket and push-to-talk
switch
