Description

The new G amplifiers are not only real powerhouses, but also combine innovative technology, great functionality and excellent sound characteristics with an absolute top price-performance ratio.

In addition to features such as the active crossover with high pass, low pass, bandpass and bass boost, the “Input Mode” switch for flexible distribution of input signals and the intelligent high-level input with ADEP circuit offers the G series with the start-stop capability an extraordinary feature in this price range. But that’s not all – a level remote control for subwoofer applications is also included.

Thus equipped, the realization of completely individual, sound and power-loaded Car Audio system concepts becomes child’s play. The HELIX-typical, compact and straight-lined design with the illuminated logo is also unmistakable.

Special features:

Intelligent high-level input
Modern, factory-installed car radios are becoming increasingly intelligent in terms of diagnosing the connected speakers. If an amplifier is connected to the radio instead, it usually results in error messages up to the elimination of individual functions (such as faders). The new Advanced Diagnostics Error Protection (ADEP) circuitry eliminates all of these problems without unduly stressing the radio’s speaker outputs at high levels.

Start Plugability
The power supply in the HELIX G FOUR amplifier ensures the internal power supply even with short-term drops down to 6 volts. This ensures that the HELIX G FOUR remains fully functional even when the engine is started.
