The SW664 Mobile Line Array Hailer System by AmpliVox combines four horizontally mounted tapered horns in a vertical column to provide clear sound coverage up to 1 mile away. The four horns provide a frequency response of 200 to 15,000 Hz into an 8 ohm load with a sensitivity of 124 dB (at 1 meter with 1 watt input). The horns are aligned on a vertical stand and disperse sound 60° horizontally and 40° vertically. This makes the system useful for both loud indoor and open-air outdoor applications such as manufacturing facilities, outdoor venues, ball fields, parks, street fairs, and other similar areas.
The speaker pole is made from weatherproof ABS plastic with a threaded stud for mounting on the heavy-duty tripod stand. An amplifier pole allows you to mount the 50W stereo amplifier which includes an integrated 16-channel UHF 584 to 608 MHz wireless microphone receiver. A wireless handheld microphone is included and a wireless headset is available (sold separately).
The amplifier features a separate master volume control, and separate volume and tone controls for its 1/8" auxiliary jack. A 1/4" wired microphone input allows for connection of a third microphone. The unit can operate for 200 hours when powered by ten D-cell alkaline batteries (not included). A rechargeable Nicad battery pack is also available (sold separately).
