Altec Lansing SLS6221 Powerful Subwoofer, World’s Smallest Line Array, Additional Features

SLS6221	Advanced Technology	SLS6221
	Delivers Predictable Sound Coverage

Whether placed at the head of a corporate board room or as part of a high traffic point-of-sale retail kiosk surrounded by reflective surfaces and high ambient noise, the sound must be delivered to its audience with minimal impact to surrounding locations. The Altec Lansing SLS6221 uses patent pending line array technology to focus voice and music into the area directly in front of the plasma screen.

Powerful Subwoofer

A ported subwoofer completes the sound with low-frequency, full-throated bass. Set in a low-resonance

wood cabinet for maximum sound with minimal distortion, the narrow-profile cabinet contains a long-

throw 6.5” (165 mm) woofer designed to reproduce dynamic audio program material down to 32 Hz.

The subwoofer also contains seven discrete power amplifiers and the line array circuitry.

The World’s Smallest Line Array

The Altec Lansing SLS6221 features two ultra-slim satellites with a total of twelve 1” neodymium micro drivers, with each pair of micro drivers powered by its own discrete amplifier. From 150 Hz to 20 kHz, the frequency spectrum is split into three distinct overlapping bands and fed into micro drivers that are set at a precise distance from each other. A combination of precise driver spacing and low pass filters for each pair of drivers delivers a predictable vertical coverage pattern of 40˚ – 60˚ above 1,500 Hz. The end result is a crisp, high-fidelity, fully intelligible sound that is focused on the listening area.

Versatility of Installation

Each SLS6221 system comes with three convenient mounting options:

•Bracket system to mount the speakers to the center mounting position of most FPDs.

•Satellite stands for use on table tops.

•Threaded inserts on the back of each satellite for surface or ceiling mounting using standard industry mounting brackets.

Note the controlled, uniform vertical dispersion pattern of the high-frequency program material. The audio is directed at the listener, not at floor or ceilings. The music and voice reproduction comes right at you, in its purest, most natural form uncluttered by reflections.

Orange = Discernable sound

Low pass filtering actively directs specified frequencies of sound to a different pair of micro drivers. This process, combined with the critical distance between each micro driver, creates the focused coverage pattern in front of the flat panel display.

Hard-wired cables (3 m / 9.8 ft.) with an additional extension cable (2 m / 6.6 ft.)

are provided for satellite to subwoofer connections. A stereo RCA input cable (5

m / 16.3 ft.) is also provided for connecting the FPD to the subwoofer.

Additional Features

•SLS6221 satellites are magnetically shielded to work with any kind of display, including standard CRTs. The subwoofer is not magnetically shielded.

•A wired control pod and wireless IR remote allow you to adjust volume, bass and treble, as well as mute the entire system.

•A headphone jack located on the control pod allows private monitoring of the audio output. Use of the headphone jack mutes the speakers.

•The SLS6221 is offered in 120 V, 220 V and 230 V versions.
