The Clear-Com Series 500 intercom stations incorporate the most advanced beltpack design available. They are incredibly rugged (will survive a drop of 60 feet) with excellent audio quality. Designed for maximum speech intelligibility in high-noise environments, these beltpacks are ideal for live performance, television, industrial, aerospace, school, and rental applications.

In high-noise environments, the beltpack mic gain can be switched to a low setting to reduce overload and distortion.

These beltpacks feature noiseless, digital electronic switching of all audio circuits, controlled by a custom integrated circuit. The high-quality “touch” controls on the beltpacks are virtually indestructible. Their size and location on the beltpack allow operation by touch, so the operator doesn’t have to see the beltpack to use it.

The audio headphone circuitry features push-pull power output, allowing the beltpack to drive a headset to very high listen levels. In addition, the limiter compensates for variances in individual voices and eliminates distortion due to overloading of the mic preamp.

If an intercom user removes his headset near a loudspeaker or monitor and forgets to turn off the mic, the high noise may overwhelm normal communications. The problem is the open microphone cannot be easily found. The Remote Mic Kill function in the beltpack solves this problem by enabling the beltpacks’ microphones to be shut off from the Main Station or any other location (using optional RMK-1).

In addition, when any beltpack is disconnected from the intercom line, the beltpack’s microphone circuit is instantly shut off, preventing any squeals or “pops” in the headset.

Visual “call” signaling is used to attract the attention of operators who have removed their headsets. All beltpacks include visual call signaling with very high-intensity, multi-segment LEDs as standard features.
