HELIX G FOUR
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 to performance ratio.
If we do not talk about their more obvious features, such as fully active crossovers with highpass, lowpass, bandpass, bass boost and input mode switch for flexible input signal routing and smart high level input with ADEP circuits, we can still talk about how the G series also provides Start-Stop capability which is an exceptional feature in this price range. Wait, that’s not all… a remote control for adjusting the subwoofer level is included as part of the deal.
With such an extensive list of features in this piece of equipment, it is really not hard to realize a sound system in your car that has a great sound and lots of power for when you need it most.
Furthermore, the G amplifiers have the compact and straight HELIX design that has become synonymous with HELIX. In addition, for those who love a good light show, the logo has been illuminated for your viewing pleasure.
Features
- Start-Stop capability down to 6V supply voltage
- Smart highlevel input with ADEP circuit (Advanced Diagnostics Error Protection)
- Fully active crossover with highpass, lowpass, bandpass and bass boost
- Extremely stable output stage with high-current power transistors
- Cable remote control for volume adjustment of the channels C and D
- “Input mode” switch for flexible input signal routing
- Highlevel input sensitivity up to 14 Volts max.
- 2-channel PreOut for the connection of additional amplifiers
- SMD (Surface Mounted Device) manufacturing technology combines minimum space requirement with maximum reliability
- Exclusive compact and clean design with illuminated HELIX logo
Special features:
Smart highlevel 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 (e.g. fader function) quite often appears - but not with the G FOUR.
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 FOUR assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.
