Weather resistant, Indoor/outdoor, Omni-directional pre-amplified microphone and  70V 10W, 6x6 Inch armored square horn speaker for use in two way public address audio surveillance systems. The HSM6-DP's microphone is concealed in the speaker sound chamber which protects the microphone from weather and converts the microphone into a directional pattern pickup with -12db attenuation (at 90 degrees) on all sides. The HSM6-DP also contains a high performance microphone pre-amplifier with adjustable hi pass and low pass audio filters and AGC.

The HSM6-DP speaker microphone in combination with our DNR-1 noise canceling processor, is ideal for use in outdoor applications where voice communications intelligibility is of critical importance.
