Speaker buying guide for Acoustic Research AW822 900 Mhz Outdoor Wireless Speakers


Enjoy your favorite music all around your home with the Acoustic Research AW822. Its wireless technology and built-in amplifier give you the freedom to listen to your tunes in just about any room. You can even use this speaker outside on a deck or patio, thanks to its weather-resistant construction. A built-in handle makes it easy to carry along with you when you're doing chores or just having fun.

Simply connect the included wireless transmitter to a home stereo, MP3 player, or portable audio system, and power the speaker using the included AC adapter or eight "C" batteries. The transmitter sends the signal through walls, floors, and ceilings — letting you enjoy your music from up to 250 feet away.

A three-in-one power/volume/tuning button puts all of the essential controls in one convenient location. And a left/right/mono switch lets you use one AW822 in mono mode, or team it with another '822 for wireless stereo sound.

Features

Transmitter: The system comes with a Radio Frequency omnidirectional transmitter/charger that connects to an audio source via analog stereo preamp connection. It transmits a 900 MHz signal up to 250 feet to the wireless speaker, using one of three selectable transmission channels. A channel select switch on the transmitter allows the use of other 900MHz equipment in the same area as the speaker is being used to avoid interference.

Speaker: The self-powered, 7.5 watt speaker is a Two-way acoustic suspension design capable of outdoor use. The speaker features a 2" dome tweeter and 5" cone woofer which are powered by a self-contained 7.5 watt digital amplifier with a 40 to 15kHz frequency response. The speaker has a left/mono/right switch on the right side of the speaker so you can use the speaker as a stereo pair in one location matched with another AR AW822 (optional) or as separate mono speaker in your desired location. The speaker is powered by either the supplied AC power adapter or by 8 "C"-cell batteries (not included). The battery compartment is located on the bottom of the speaker and requires three phillips-head screws to be removed.

Note: If you are using rechargeable batteries, the batteries will charge when the speakers are powered with the AC power adapters. The AC adapters will charge rechargeable NiMH or NiCd batteries (not included).

Audio Signal Indicator Light: There is an audio signal indicator light on front of the transmitter that lights Blue to inform you that the transmitter is receiving an audio signal from your source component.

Integrated Power/Tuning Volume Control: The speaker has an integrated Power/Tuning/Volume knob near the bottom of the cabinet. Press the rotary knob in to turn the power for the speakers "On" and to start tuning the speakers. The "power/tuning indicator" on the bottom of the speaker will illuminate Red while the speaker is automatically tuning to the transmitter. The light will turn Blue once the speaker is properly tuned.

Auto Tune: The speaker will automatically retune if it loses the signal from the transmitter. However, you can also press the integrated control to retune the speaker at any time. While the speaker is tuning, the indicator light will turn Red and then once the speaker is tuned the light will turn back Blue.

Phase-Locked Loop: Phase-Locked Loop technology guarantees crystal clear audio from the speaker by locking onto the transmitter's signal for more precise, accurate tuning.

Turn Off: Push and hold the integrated control in for about 1.5 seconds to turn the speaker off. Confirm that the speaker is off by verifying the "power/tuning" indicator light is no longer illuminated.

Built-In Carry Handle: The speaker's built-in carry handle lets you move the speaker easily from place to place.

Transmitter: The 900Mz transmitter uses an attached 6' male mini-jack cable and comes supplied with a mini to stereo RCA adapter and a 3/4" headphone adapter. The unit also features a DC input for use with the supplied AC adapter.
