New HELIX D amplifiers
The new HELIX D amplifiers open new horizons in terms of price performance ratio. It is the first time that HELIX offers a lot of amplifier performance for such a low budget without neglecting the proved HELIX quality.
Amplifier pack convinces at first sight through high-quality processing in many details. The fine brushed aluminum heatsink and the stylish HELIX-logo make these models very attractive.
The new D 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 which is exceptional in this price range.
With such an extensive equipment the configuration of individual powerful but good sounding car audio systems is easy to realize. Furthermore the D amplifiers have the typical compact and straight HELIX design with brushed aluminium heatsink.
FEATURES:
• High- and lowlevel input
• Smart highlevel input with ADEP circuit (Advanced Diagnostics Error Protection) and Auto Turn-On function
• Fully active crossover with highpass, lowpass, bandpass and bass boost
• Extremely stable MOSFET power supply
• Highlevel input sensitivity up to 14 V olts max.
• “Input mode” switch for flexible input signal routing
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 D 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.
