Amplifier Topology

The range of Powerbox Mini class D multi-channel amplifiers feature a MOSFET output stage usually reserved for large platform amplifiers, the class D topology is much more efficient that the traditional class AB used in this style amplifier, this means the amp can be smaller and stay much cooler during operation. This delivers not only higher power output but also fantastic sound quality and the ability to bridge channels to drive a subwoofer making these a perfect one amplifier solution. The high efficiency design means less current draw and less strain on the factory charging system.

Deltabox Connectivity

Our Powerbox Mini amplifiers have inputs options to ensure that any system can be utilised to connect to these amps. Our high quality RCA inputs offer 0.5v – 6v input voltage alongside a new Deltabox™ High level input circuit which gives Autosense remote turn on for use with factory systems. This eliminates the requirement to use a separate line level convertor and accepts an input voltage of up to 35v! This offers a perfect range of connectivity. Deltabox™ High level input circuit paired with the High quality High Level inputs allows the amp to use a DC offset Auto sense turn on feature so no remote turn on is required when using this installation method, the DC offset method offers a much more stable and reliable turn on methodology compared to the traditional signal sensing.

OPTISOUND Advanced OEM Integration

VIBE R&D partnered with the best amplifier designers in the car audio world to ensure our amplifiers perfectly integrate with the most modern of vehicles. Our amps feature technology that stops the autodetection problems and OEM Error messages that are displayed if installing common amps into new modern vehicles. The technology stop the vehicle sensing changes in resistance therefore giving no installation issues, such as cutting out of speakers, disappearance of fader and more. Our Powerbox amps are perfect for OEM installation. The OPTISOUND Range has become the go to upgrade of choice for many dealers when forced to retain the factory head unit.

VIBE Sound Studio Active Crossovers

Utilising High and Low pass filters with a natural 12dB slope allows the 4 channels of amplification to be run passive and active systems safely. The amp also feature an incredible 10hz – 30Khz bandwidth when being used in FULL RANGE mode allowing you to take full advantage of even the highest ranging tweeters! This delivers suitable amplification for high bit rate sound reproduction and makes the VIBE POWERBOX range a great choice for demanding Sound Quality systems. The VIBE Sound Studio™ active crossover networks are a simple and easy way to run speakers fully active without the need for complex crossovers.
