About the Polk Audio SurroundBar® 4000 Instant Home Theater

Kristen Schaub
Polk's SurroundBar 4000 is a sleek, easy-to-use system that creates exciting, three-dimensional home theater sound without the home theater clutter. This slender sound bar perfectly complements flat-panel TVs, and connects via a single audio cable for an incredibly easy setup. Built-in decoding for Dolby® Digital audio means it'll work with just about any recent TV. Dolby Digital is the audio format for all over-the-air HDTV broadcasts, and many TVs can only output Dolby Digital.

Big bass from a convenient wireless subwoofer
A separate subwoofer adds punchy bass impact to the mix. Plus, the sub's wireless design means it can be placed just about anywhere in your room. Both the sound bar and subwoofer have built-in amplifiers, adding oomph to all your favorite TV shows, movies, and video games without the need for a receiver.

Polk's proven audio processing delivers more dramatic, engrossing sound
The SurroundBar 4000 features Polk Digital Logic™, for more realistic sound that goes far beyond what TV speakers alone can deliver. So, whether you're watching a football game on TV or fighting to save the princess in your favorite video game, screaming fans and growling monsters seem to fill the entire room and immerse you in the action.

    System Features

    Instant Home Theater (IHT): The Polk Audio SurroundBar 4000 Instant Home Theater (IHT) is a complete 2.1-channel home theater system comprised of a single self-powered speaker, a wireless powered subwoofer, and an IR remote control. The SurroundBar 4000 IHT utilizes Polk Digital Logic (Polk's Proprietary DSP Technology) to deliver richer, fuller sound (with no rear speakers) to your flat-panel TV from a compact system with no complex hook-up or set-up.

    Polk Digital Logic: The SurroundBar 4000 Instant Home Theater utilizes Polk Digital Logic (Polk's proprietary DSP programming) to deliver big, crisp sonic performance with no complicated setup or calibration. Through Polk Digital Logic, the SurroundBar 4000 IHT's sound is created independent of any room boundaries. Polk Digital Logic helps to maintain a solid center channel for clear, intelligible dialogue and Polk's signature warm & full sound.

    Self-Powered SurroundBar: The self-powered surroundbar features two 2" x 6" full-range drivers powered by a built-in 50 watt x 2-channel amplifier. The speaker itself is lightweight in part because of the neodymium magnet structures in the drivers. The surroundbar features a black plastic enclosure with non-removable metal grille. The surroundbar can be placed on a tabletop or wall-mounted. It provides analog and digital audio connections to your television. The surroundbar requires AC power.

    Wireless Powered Subwoofer: The wireless powered subwoofer features a down-firing 6.5" woofer and down-firing port in a bass-reflex (ported) cabinet. The 6.5" woofer is powered by a built-in 80 watt amplifier. The wireless powered subwoofer receives it audio signal wirelessly from the system's surroundbar, so there is no subwoofer cable to connect. The wireless powered subwoofer requires AC power.

    Controls

    System Controls: The SurroundBar 4000 IHT offers the following system functions - Power, Surroundbar Volume, Subwoofer Volume, Source Selection, and Mute. You can control these functions from the Surroundbar's touch-sensitive controls, included remote control, or your TV's programmable remote control.

    Touch-Sensitive Controls: The touch-sensitive buttons on the front of the surroundbar are easy to use.

    Remote Control: The included IR wireless remote provides wireless operation of the SurroundBar 4000 IHT.

    Programmable TV Remote: You can program the SurroundBar 4000 IHT to respond to your existing TV's remote.

    Channel ID: The channel ID switches on the rear-panel of the surroundbar and subwoofer need to be set to the same channel (1-4).

    Connections

    Wireless Connection: The SurroundBar and powered subwoofer communicate with one another wirelessly. The SurroundBar sends the low-pass audio signal from your TV or connected source to the powered subwoofer wirelessly over an RF frequency.

    Note: The SurroundBar and powered subwoofer come from the factory preset to work together. If the wireless subwoofer stops receiving an audio signal from the SurroundBar, there is a sync button on back of the SurroundBar to press to regain system connection.

    Analog & Digital Connections: The surroundbar features one optical digital input and two stereo 3.5mm inputs to connect the system to your flat-panel TV.

    Analog Connections: The surroundbar is equipped with two analog 3.5mm stereo inputs to connect your television (which may lack an optical digital output). If your TV is equipped with stereo RCA outputs, a minijack-to-RCA adapter is provided. The additional 3.5mm stereo input can be used to connect another audio device, such as your MP3 player.

    Digital Connection: The surroundbar also features an optical digital input to connect your flat-panel TV with an optical digital output (optical digital cable included). The surroundbar supports 2-channel PCM & Dolby Digital through its optical digital input.

    Mounting Options

    Placement Options: The SurroundBar 4000 Instant Home Theater offers various placement & mounting options for the surroundbar & wireless powered subwoofer.

    Surroundbar Placement: The surroundbar should be centered under or above your TV screen. The lightweight easy-to-mount single speaker can be placed on a tabletop or wall-mounted. It can sit on a flat surface because of its attached rubber pads that enable it to rest securely. If your TV is wall-mounted, the surroundbar can be mounted right beneath it using the speaker's integrated keyhole slots (x2) on the rear-panel.

    Note: The keyhole slots are spaced 16.75" apart.

    Wireless Subwoofer Placement: The powered subwoofer receives its signal from the surroundbar wirelessly, so it can be placed virtually anywhere in the room (up to 50' from surroundbar). It only requires plugging into an AC outlet.

    Power Requirements

    Power Supply: Both the surroundbar and wireless powered subwoofer require an AC outlet connection using the supplied AC power supply and AC power cords.

    Auto Power: When their master power switches are left on, the amplifiers in both the surroundbar and subwoofer turn on automatically when the surroundbar receives an audio signal. Both amplifiers turn off after approximately 15 minutes without an audio signal.
