New GZDSP 4-8X Provides 8 Channels, Bluetooth streaming, PC programming

DAVIE, FLA., December 5, 2018 (MEDIAWIRE) – Fresh off the introduction of its high-performance GZDSP 6-8X PRO digital signal processor, Ground Zero is introducing a concentrated version for use in mainstream audio systems. The GZDSP 4-8X maintains many of the features of the German audio manufacturer's flagship model, including eight-channel output, PC setup, per-channel parametric equalization and user presets. But rather than use the more extensive unit for every application, technicians can create multi-channel audio systems from traditional four-channel source units with the GZDSP 4-8X.

"System builders told us, as good as the GZDSP 6-8X PRO is, in many cases it's overkill for simpler systems," said Diogo Ianaconi, CEO of SounDigital, which is the official U.S. distributor of Ground Zero. “The new GZDSP 4-8X is a better fit for certain applications. And as the industry is trending more toward DSP, it gives stores the ability to broaden their customer base by being able to offer DSP at a lower price point."

With a height of just one inch, the GZDSP 4-8X fits under seats or behind panels. It accepts high- or low-level signals and processes the input with time alignment and 10-band parametric equalization, both adjustable for each of its eight output channels. The resulting signal can then be tailored to accommodate high, mid and subwoofer frequencies with high-end filter characteristics, adjustable crossover frequency and slope, and subwoofer phase selection.

Tuning adjustments are made through an attached PC with proprietary software, or through the Ground Zero DSP application, available from major phone maker app stores. The latter requires the new GZDSP BT-STICK, a Bluetooth®-enabled USB dongle that allows direct wireless music streaming and communication between the DSP and phone-based app. User adjustments are possible with the plug-in wired remote, which allows volume control and selection of up to six presets.

The GZDSP 4-8X has an MSRP of $470.00. For more information, visit bit.ly/gzdsp4-8x, or contact SounDigital at This email address is being protected from spambots.

GZCT 500IV-B adds to the brand’s Competition Series line

DAVIE, FLA., March 28, 2019 (MEDIAWIRE) – SounDigital USA, exclusive U.S. distributor of Ground Zero audio products, announced that the Ground Zero GZCT 500IV-B tweeter is now available to authorized retailers in the U.S. and Canada. The new speaker, introduced at the 2019 KnowledgeFest trade show and education conference in Indianapolis earlier this month, is a high-performance compression tweeter from the brand’s Competition Series, designed specifically for motorcycles. Its introduction gives bike audio retailers a versatile, high-frequency driver in a design ideal for custom installations.

The GZCT 500IV-B features a compact diameter for minimal surface area installations. Its screw-on bezel provides an attractive surface-mount solution for drop-in replacement or custom installs, and rust-resistant rear screw terminals connect it to the radio or amplifier. It’s capable of 30 watts RMS and 100 watts maximum power handling with a rated frequency response of 4kHz – 25kHz.

The element-resistant black chassis houses an aluminum dome tweeter and cast baffle, driven by a one-inch, copper-clad aluminum flat-wire voice coil capable of four-ohm impedance loads. A plastic phase plug enables installers to mount the tweeter to fire toward the rider from the front or rear.

“Our response from retailers at KnowledgeFest was phenomenal,” said Diogo Ianaconi, CEO of SounDigital USA. “Traditional bike audio retailers who know the quality of Ground Zero tweeters liked its crisp, clear performance. And several car audio retailers that don’t typically do bike installs are now seeing a new profit center. We think the new tweeter will be a popular addition to Ground Zero’s Competition line.”

The GZCT 500IV-B has an MSRP of $99 each and is sold as a single speaker.

“SEMA is going to be a massive event for us,” said Michael Ventura, National Sales Manager. “We will be using this event as a spring board into 2020. The announcement of an entire new line up for SounDigital is going to be huge.” This new line under the EVOX banner has been in development for the past several years and is currently patent pending. “The power to size ratio is incredible. Never has the market seen such small foot print making the power these new amplifiers will”, said Ventura. SounDigital and Ground Zero have partnered with Blaze Performance Cycles from Clayton, North Carolina to feature their fully customized Harley Davidson Road Glide. “This bike has over of 12,800 watts of clean SounDigital power and it all fits in a tour pack! Rounded out for sound by 25 Ground Zero competition speakers including some top secret black baskets will make it one of the loudest demo vehicles on the show floor.”

The SounDigital booth will also feature a 1957 Chevy C10 truck built by Mobile Toys Inc. from College Station, Texas. This vehicle will feature Ground Zero Plutonium SQ series speakers and SQ amplifiers, as well as its Titanium high quality flat sub woofers.  “This truck is going to showcase Ground Zero award winning capability,” Ventura said. “Ground Zero is a major player in the European and Asian markets and we will intent to show the US dealer why.”

DANIA BEACH, Fla. -- SounDigital USA is excited to reintroduce a legend in the car audio industry. After years (and years and years and years) of being asked, SounDigital has decided it needed to step back into the realm of High End Car Audio, and bring back the legendary GaN amplifier.

This new series of amplifiers is a step up from the previous iteration, and will provide dealers with a much more versatile solution for their clients. SounDigital is doing things a bit different with this line, and that is making a product exclusive to select car audio retailers. It is important to understand why GaN is different, why it is going to be used specifically in an automotive application, and why this product is not being put into application in the powersports world.

This is why the team at SounDigital USA has decided to introduce the product to all retailers at KnowledgeFest Dallas, and focus their training time to let car audio retailers know why this product is special. 

If you are a car audio retailer attending KnowledgeFest Dallas, make sure to swing by the booth when the floor opens, and make sure you attend the training on Saturday Evening, to get the real scoop on GaN. For more information about SounDigital, please visit http://www.SounDigitalUSA.com or e-mail This email address is being protected from spambots.
