SOUNDBASE.330 Overview


If you have a TV in a medium-sized or smaller room, the SoundBase 330 could be the perfect sound system from you. The 24" wide 330 will fit on a 13" deep shelf, plus lots of other small places. The all-digital 330’s ingenious processing adds clarity and impact to speech, video sound effects and music. Our PhaseCue virtual surround technology allows sound effects to fill your room. You quickly forget that all the sound comes from only one compact cabinet. Like the best multi-cabinet sound systems, the SoundBase 330 has individual Left, Center and Right speakers, plus a 5.25" powered subwoofer, all housed in a robust wood cabinet. You will hear super-clear dialogue and smooth musical sound, from a system that works with your existing remote control.

Only 3.5" high, you can place the SoundBase 330 under your TV, or place it on furniture somewhere near your TV. It’s a good match for most TVs from 27" – 42" in size. And it’s loaded with cool features: Our AccuVoice technology delivers super-clear voice reproduction. Output Leveling tames loud commercials. Remote Learning lets the 330 work with your current remote. Connect the 330 to any TV’s digital audio output. Additional analog audio inputs allow you to connect additional audio devices.

It's likely you have a TV in a bedroom, office, den, workshop or kitchen that you listen to a lot. That TV is calling out for a SoundBase 330 home theater system.

More Detail for the Detail-Minded

Dialog up, commercials down. If you can't hear the actors, it's nearly impossible to follow the story. That's why ZVOX created our AccuVoice feature that gives voices new clarity and prominence. What's more, ZVOX knows how sponsors love to blast us out of our seats during commercial breaks. The 330’s Output Leveling feature clamps down on commercial outburst, so you can just relax.

Big sound from a small console. This one-piece system houses three full-range speakers, a high-output woofer, and built-in amplification — there's no need to use a separate receiver or run wires to any external speakers. Plus, the 330 is designed to serve as a convenient base for flat-panel TVs with screen sizes up to 42". Even older TVs sit perfectly atop this sturdy wooden cabinet, since it can support up to 50 lbs. Place the SoundBase 330 directly underneath your TV and you won't have to worry about making extra room for it on your entertainment cabinet.

Built with convenience in mind. You can connect iPod® or portable player to available extra inputs for terrific sound. The display on the 330 lights up from behind the front cloth grille then disappears when not in use. And the 330 learns the commands of your TV remote, giving you one less clicker to keep track of. Cable or Satellite remote control-sensing circuitry powers the system on and off along with your TV.

Crystal-Clear Vocals. Our AccuVoice Dialog Emphasis feature uses hearing aid technology to make voices unbelievably clear. It's amazing.

Tame Loud Commercials. Tired of commercials that blast you out of your chair? Our Output Leveling feature reacts instantly and turns them down to a lower level. You'll love it.

PhaseCue® Virtual Surround Sound. The 330 uses ZVOX's proprietary PhaseCue virtual surround processing to give you rich, three-dimensional sound with movies or music.. While no virtual surround system - including ours - will give you the surround effects of surround sound systems with multiple speaker cabinets, the ZVOX 330 does a remarkable job. Sound & Vision magazine calls our PhaseCue processing "remarkably ingenious."

Disappearing Display. The 330 features a four-digit display located behind the speaker grille that shows the current setting for volume, bass, treble and PhaseCue® (virtual surround) - and also shows when you have engaged the Mute, Output Leveling (OL) or AccuVoice (AV) features. A few seconds after you stop using your remote (or front panel) controls, the display disappears completely.

Multiple Inputs. The 330 has two analog audio inputs, plus one digital audio input (supports both optical [TOSLINK] or coaxial digital cables). Any specific input can be selected using either the SoundBase’s remote control or the slim-line button panel on the SoundBase cabinet.

Just Plain Great Sound. The most important feature for any home theater system is high quality sound. The 330 uses premium quality speakers and amplifiers and was designed by our team of "New England Sound" speaker designers. We think you will be amazed at just how good such a small system can sound.

Uses Your Remote Control. The SoundBase system can be programmed to respond to your remote control -- it takes less than a minute. Then your TV remote...or cable box remote...or satellite receiver remote...can control volume, mute and power functions of the ZVOX system.











Technical Details
  • Dimensions: 23.7"W x 11.5"D x 3.5"H
  • Weight: 12 pounds. With box and packing: 17 pounds.
  • Amplifier: 40 watts with digital power supply.
  • Rear inputs: Supports one digital audio signal connection, from (1) optical (Toslink) digital jack or (1) coaxial digital jack. Supports two analog stereo inputs (L/R RCA jack pairs)
  • Frequency range: 55 Hz - 20 kHz.
  • Virtual surround sound: The 330 uses ZVOX's proprietary PhaseCue virtual surround sound processing. PhaseCue, as its name implies, manipulates the phase of the separate channels to "fool the ear" into believing that sound is coming from a variety of sources throughout the room. The benefits of PhaseCue vary greatly based on program material. Live music and well-recorded modern movie soundtracks will deliver rich, three-dimensional sound - pulling the sound out from the speakers and into the room, literally surrounding the listener. Note: All virtual surround systems - including the PhaseCue system - are limited in their effects when compared to a good multi-cabinet 5.1 system. And sitcoms, news broadcasts and soundtracks from older movies often have very little in the way of three-dimensional sound. That being said, PhaseCue is capable of generating a wonderful and engaging virtual surround experience.
  • The 330 is bi-amplified, using a specially designed amplifier that includes electronic contouring for superb frequency response.
  • The 330's 5.25" subwoofer uses a high-mass long-throw design in a ported enclosure.
  • The 330's three 2" main speaker drivers use a long-throw design to create remarkably wide range, accurate sound.
  • Unlike most systems in its category, the 330 uses an MDF (medium density fiberboard) wood cabinet - instead of molded plastic. MDF is the preferred construction material for high-performance speaker systems.
  • Works with 100-240 volt power systems.
  • The ZVOX 330 is backed by a one year limited parts and labor warranty.

It's Compact

The Z-Base 330 is only 23.7" wide by 11.5" deep by 3.5" high. Everything is inside this compact cabinet - speakers, amplifier, virtual surround circuitry and powered subwoofer.

Simple Installation

The 330 requires only one connecting cord -- both analog and digital signal connections are supported. Connect the one cord and you're done. You can place the 330 directly beneath most 27" - 42" TVs. (*TV base should not exceed 22" in width or 10" in depth. TV should not exceed 50 pounds in weight. Safety instructions in Z-Base 330 Operating Instructions and in TV's Operating Instructions should be closely examined and followed.)

Simple To Use

In about one minute you can follow a simple routine that will "teach" the ZVOX 330 to respond to the commands of your TV or cable/satellite remote control. So you can adjust volume, mute, input and power with your remote, not ours. When you've finished the routine, turning on your TV will automatically turn on the ZVOX system. About three minutes after you turn off your TV, the ZVOX system will automatically go into standby mode.

Virtual Surround Sound

The 330 uses ZVOX's proprietary PhaseCue virtual surround processing to give you rich, three-dimensional sound with movies or music. With music, PhaseCue creates a very wide soundstage - it literally sounds like you are listening to speakers eight feet apart from each other. When listening to a good movie, the soundtrack will envelope you - putting you in the middle of the action. While no virtual surround system - including ours - will give you the surround effects of a good 5.1 system, the ZVOX 330 does a remarkable job. Sound & Vision magazine calls our PhaseCue system "remarkably ingenious."

No Skimping On Speaker Quality

Most audio systems in our price category use very cheap speakers in plastic cabinets. But at ZVOX we're "old school" about things like this. We use nothing but high quality speaker drivers, carefully designed by ZVOX engineers and manufactured to our specification. The 330 uses specially treated long-excursion main drivers. The cabinet is MDF (medium density fiberboard), the same material used in most high-end loudspeakers.

10 Reasons To Choose
ZVOX Home Theater Systems
  1. Better Sound. Most speaker companies seem to be entirely focused on features. We're focused on sound quality. Our Design Team, headed by industry veteran Jarl Salmela, is the best in our category. We use high quality amplifiers and speakers in robust cabinets to make true high fidelity speakers. Look at our consistently high consumer ratings and our long list of Editor's Choice Awards. Or better yet, use our 60-day home trial and listen for yourself.
  2. Center Speakers. It is not cheap to have dedicated center speakers and amplifiers in a TV sound system. Which explains why ZVOX systems are the only ones in our price range that include center speakers. We think center speakers are worth it because they deliver richer, more anchored midrange sound reproduction – and super-clear voices.
  3. AccuVoice Feature. Our AccuVoice feature uses hearing aid technology to create crystal-clear voice reproduction. No other brand offers this technology. With TV sound systems getting smaller and smaller, TV dialogue is often muddled and incomprehensible. AccuVoice fixes that.
  4. Wood or Aluminum Cabinets. Virtually all sound bars and base-style home theater systems use plastic cabinets. Because plastic is cheap, and you can form it into cool, curvy shapes. But wood/MDF (medium density fiberboard) and aluminum make much better speaker cabinets – providing better strength and rigidity, and lower resonance. That's why we use these materials, even though they are much more expensive.
  5. Multiple Inputs. ZVOX systems aren't just for TV – our sound systems have a choice of selectable inputs–including wireless Bluetooth reception. So you can connect an external wifi audio receiver (like Chromecast Audio or a Play-Fi receiver), tablet/phone, CD player or even some turntables – anything with an audio output.
  6. A Real Display. Our display tells you your volume level, bass and treble setting, surround modes and much more – then disappears when not in use. Our competitors just have flashing lights.
  7. Great Subwoofers, Built In. ZVOX sound bar and SoundBase systems deliver deep, accurate bass without the need for an external subwoofer cabinet and wires.
  8. Actually Works With Your Remote. Other companies may claim that their systems can work with your remote. Ours really do.
  9. The Right Size For Every TV. We offer SoundBase and sound bar systems in a variety of sizes and shapes. No matter what size TV you have, there's a ZVOX that with work well with it.
  10. Lowest Prices Ever. We're now offering our lowest prices ever on all of our sound systems. Don't delay – now is the time to get a ZVOX!
ZVOX 60-Day Home Trial
