Extended range, use for all species of pest birds except geese. Touted as the next generation in Ultrasonic Pest Repellers, the Bird-X Quad Blaster QB-4 Ultrasonic Bird Repeller is a step up from its brother, the Ultrasonic X, due to its extended coverage area of up to 6500 square feet. Ideal for use on most all types of bird species, this "silent to humans" ultrasonic model is ideal for residential, commercial, and industrial properties alike.

A step up from the Ultrason X, the Bird-X Quad Blaster QB-4 Ultrasonic Bird Repeller covers up to 6500 square feet (90 foot diameter circle) and is designed to act as an important aid in routing birds from their infestations in plants, warehouses and semi-enclosed locations such a loading docks, railroad sidings, tunnels, breezeways, underpasses and storage sheds.

The Bird-X Quad Blaster QB-4 mounts in any direction to send sound where you need it. Four Piezo ceramic speakers project powerful ultrasonic sound waves in all directions. Made with advanced solid-state circuitry, with no moving parts, it makes for a trouble free operation. Two red diodes indicate rate of "warble" and speaker sequencing. With contemporary low-profile housing of sturdy, durable steel, four green LEDs show each speaker's sound output. Stop annoying birds from causing property damage and costing you maintenance dollars. Eliminate dangerous health and safety hazards. Rid your premises of unsightly and potentially virulent bird droppings. Avoid persistent bird nuisance.

The QB-4's four Piezo ceramic speakers emit overlapping patterns of ultrasonic sound waves that zero in on the birds (people can't even hear them). Sounds are sent out 45 feet in all directions. Mount the QB-4 in any direction and on any surface. Just plug it into any 110 vAC outlet and watch your bird problems fly away.

HOW IT WORKS - The new BIRD-X QB-4 uses solid-state electronic circuitry to produce harsh, but harmless, UHF sound waves. These sound waves are targeted at overhead bird infestations. Their frequencies are above the human hearing range, so most people are not even aware of them.

Four powerful Piezo ceramic speakers, placed 90 degrees from each other, produce a dispersion of overlapping "fans" of sound for full 360 degrees coverage. The QB-4 may be regulated to maximize effectiveness. Speakers may function at a constant 20 kHz, modulate between 20 and 30 kHz at different speeds (producing a "warble") or in a combination mode which alternates constant and "warble" output in 12 second bursts. The speakers can also be "sequenced" (in rotating order) at speeds from 10 to 110 rpm.

An optional accessory available for the QB4 is Remote Extension Speakers. For unusual space configurations or areas divided by walls, use up to four remote speakers to stretch sound farther.
