The new G amplifiers are more than just impressive power packs. They unite innovative technology, extensive functionality and best sound with a very attractive price-performance ratio.

Beside their features such as fully active crossover with highpass, lowpass, bandpass and bass boost, input mode switch for flexible input signal routing and smart highlevel input with ADEP circuit, the G series also provides Start-Stop capability which is exceptional in this price range . And that's not all - a remote control for adjusting the subwoofer level is included in delivery.

With such an extensive equipment the configuration of individual powerful but good sounding car audio systems is easy to realize. Furthermore, the G amplifiers have the typical compact and straight HELIX design with illuminated logo.

• Start-Stop capability down to 6V supply voltage
• Smart high-level input with ADEP circuit (Advanced Diagnostics Error Protection)
• Fully active crossover with highpass, lowpass and bandpass
• Subwoofer channel with integrated subsonic filter and bass boost
• Extremely stable output stage with high-current power transistors
• Suited for full-active mode of loudspeaker systems
• Cable remote control for volume adjustment of the subwoofer channel
• "Input mode" switch for flexible input signal routing
• High level input sensitivity up to 14 Volts max.
• SMD (Surface Mounted Device) manufacturing technology combines minimum space requirements with maximum reliability
• Exclusive compact clean design with illuminated HELIX-logo

Special features:

Smart high level input
The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common amplifier will be hooked up failure messages and loss of specific features (eg fader function) appear quite often - but not with the G FIVE.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.

Start-Stop capability
The switched power supply of the HELIX G FIVE ensures operation even if the battery's voltage drops down to 6 Volts during engine cranking.
