HELIX C FOUR

Fantastic sound quality - impressive, powerful

The C FOUR is a top-class 4-channel amplifier whose construction is dedicated to perfect sound down to the last detail. An ultra-low-noise and low-distortion driver stage in Class A technology controls a total of 32 hand-selected power MOSFETs, which have a firm grip on every loudspeaker with a damping factor of 1,000. The intelligent power supply control, which keeps the supply voltage for the output transistors of the amplifier constant, also ensures stable conditions. Thus, the phenomenal performance data of the C FOUR is independent of the operating voltage.

The C FOUR creates the perfect transition to the digital world with the optionally available SPDIF input module HDM 2. This receives digital audio signals with a sampling rate of up to 96 kHz loss-free via fiber optics and converts them via two BurrBrown stereo DA converters of the latest generation with 32-bit resolution into the analog level back. The C FOUR is therefore absolutely future-proof and perfectly equipped for the combination with our digital signal processors.

Features

✓ Extremely broadband ClassAB amplifier with eight select MOSFET transistors per channel for exceptional sound quality - ideal for high-resolution audio

Ultra low-noise and low-distortion power stage driver in ClassA technology

Enormous damping factor of 1,000 @ 4 ohms for perfect loudspeaker control

Optionally available HELIX Digital Input Module (HDM) to expand the amplifier by two optical digital inputs in SPDIF format

Integrated, active crossover with high pass, low pass and band pass

Regulated DC/DC switching power supply with start-stop capability down to 6V supply voltage

Processor-controlled monitoring of the amplifier and temperature-controlled fan control

Input mode switch for flexible distribution of the input signals

The latest generation of BurrBrown DA converters with 32-bit resolution in combination with the optional HDM 2 module

24k gold plated solid power and speaker terminals

Copper-plated 70μ conductor tracks for optimal current flow

SMD technology (Surface Mounted Device) on a quadruple multilayer printed circuit board 

Special Features:

start-stop capability

The power pack in the HELIX C FOUR amplifier ensures the internal power supply even in the event of short-term dips down to 6 volts. This ensures that the HELIX C FOUR remains fully functional even when the engine is started.

High-Resolution Audio

The extremely high audio bandwidth of this amplifier enables lossless audio reproduction of high-resolution audio signals to ensure the best possible studio-quality sound.

Wiring wizard

Use our wiring wizard for simple wiring of speakers and subwoofers or to find the optimal setup for your cabinet! The right connection is important for your amplifier! Low impedance operation can damage the amplifier!

✓ Series connection: The impedance increases in number

✓ Parallel connection: The impedance decreases in the number

The data sheet shows you which connection the respective amplifier is designed for!

Port calculator

Our port calculator shows you which tuning your housing has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

The net volume design for your woofer size in music mode can look like this

Bass reflex:

✓ 6.5" (16.5cm) = 10 - 15 liters

✓ 8" (20cm) = 20 - 30 liters

✓ 10" (25cm) = 40 - 50 liters

✓ 12" (30cm) = 60 - 80 liters

✓ 15" (38cm) = 100 - 125 liters

✓ 18" (46cm) = 180 - 240 liters

✓ 21" (54cm) = 230 - 290 liters

Products

We use several indicators for sufficient transparency in the store. All products are marked several times with the corresponding availability and delivery time. The availability indicator shows a rough overview of the stock quantity; if there is excess stock, the indicator is automatically hidden.

Items that are not available cannot be ordered.
To avoid unnecessary waiting times, we have set up an e-mail notification function for you. As soon as the goods arrive, you will automatically receive a notification of availability after entering your e-mail.

Manufacturers who provide data sheets or operating instructions can be found at the end of the item description for download.

Unfortunately, it is difficult to give a general answer, as all woofers and speakers are constructed differently and have different coils, plus the amplifier, which must be designed for the connection impedance. You can simply use our wiring assistant, enter the number of speakers, resistance and wiring variant and have it calculated. If the amplifier can handle the connection impedance, nothing stands in the way of the wiring.

Amplifiers which have a release up to e.g. 1 Ohm can also be connected with 2,3,4 and higher impedance.

Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here. Calculate the pure recorded chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.

✓ 8" (20cm) = 20 - 30 liters

✓ 12" (30cm) = 60 - 80 liters

✓ 15" (38cm) = 100 - 125 liters

✓ 18" (46cm) = 180 - 240 liters

✓ 21" (54cm) = 230 - 290 liters

If you prefer to listen to charts, rock, pop or e.g. techno, the tuning should be a little higher and is usually in the range of 40Hz and higher. The range of RnB or Ami HipHop usually plays in the 30 to 40Hz range.

In short, clipping is an "unclean signal". You can usually recognize clipping in woofers when there is an electrical smell, the woofer stinks and becomes hot. With loudspeakers, it can also be noticeable through unclean reproduction. The fun is over when the coil has unwound from the carrier. Many amplifiers now have a clipping LED integrated in the output stage or in the bass control; if the LED lights up, you should definitely turn down the volume. If the amplifier does not have an LED, the only way to position the gain correctly is to use an oscilloscope or other aids. However, this requires a certain amount of basic knowledge in order to set the amplifier correctly.

We almost exclusively offer products and manufacturers that we use ourselves and install regularly, true to the motto "quality not quantity", so we can usually tell you what to expect. All products are sensibly designed and selected to cover a wide range, for reasonable sound optimization and, above all, to achieve the desired goal. If you have any questions about your setup or plans, please contact us!
