 2.  Analogue to digital conversion (ADC) is the responsibility of the Sabre ES9840, the flagship of audio technology from California. This top-of-the-line ADC combines cutting-edge technology with the highest sound quality. Its main feature is a wide bandwidth with ultra-low noise and a very high dynamic range of up to 128 dB.

3.   The SABRE ES9080Q from ESS Technology is responsible for the reverse conversion of the digital to analogue signal (DAC)! This chip delivers flawless audio quality, supporting PCM streaming formats up to 32-bit / 768kHz and DSD up to DSD512. With a wide temperature range from - 40° C to + 125° C, the ES9080Q is ideal for premium car audio systems.

4.  Input and output matching amplifiers with absolute channel independence. Forget crosstalk! The internal circuitry of the OPA1678\79 amplifier is designed so that each channel operates completely independently. This means that even with maximum load on any one channel, the sound remains clear and crisp.

5. HIGH INPUT - For connection to OEM audio systems, a 16-channel high level input with floating load emulation is provided with an impedance range of 4 to 8 ohms with a wide input sensitivity range of 6 to 32 volts, allowing the unit to be easily integrated into any system.

6. LOW INPUT - Our product features an impressive 6-channel low level input that operates from 0.5 to 6 Volts. This is the perfect solution for all your audio devices, providing unrivalled sound quality. What makes our input special? Its impedance is 47k ohms, ensuring stable and clean signal transmission. You can rest assured that your compact players, tape recorders and tuners will operate at full power without fear of distortion or loss of quality.

7. LOW OUTPUT - the availability of 10 additional channels of line output with output voltages up to 6V RMS. This means you can connect more devices and enjoy crystal clear sound.

In today's world where sound quality is paramount, we understand how important it is to minimise unnecessary audio conversions from analogue to digital. Our digital inputs are designed to give you crystal-clear, high-quality sound without unnecessary loss.

8.  OPT-IN - S/PDIF (PCM) safe and noise immune input. Thanks to the complete galvanic isolation of the connected devices, you can be assured of reliable data transmission. The optical channel used in our system is reliably protected from external influences and cannot be a source of them. This guarantees stability and sound quality under any conditions.  Our device supports resolutions up to 24-bit and sampling rates up to 192 kHz. This means you'll be able to hear every note and nuance in your music like never before.

9. COAX-IN - The independent input supports the most demanding file formats up to 24-bit/192kHz sampling with no loss of quality. The galvanic isolation reduces electrical noise between system devices, preventing possible interference and ensuring a stable connection.

10. USB audio input is not just a convenient way to connect devices, but also one of the highest quality audio interfaces in the Hi-Fi world. The second version of the USB Audio Class 2 standard has become the benchmark of quality in the world of digital audio. Today, digital Hi-Fi and High End is unthinkable without USB support, and that's no coincidence! 

11. U-DISK - built-in player with support for all modern audio formats:

   DFF / DSF / DSD, WAV, FLAC, APE, AIFF, AAC, WMA, OGG, MP3 - enjoy music in the highest quality. 

   PCM: 44.1 kHz to 768 kHz, bit rate up to 32 bit. 

   DSD: DSD64, DSD128, DSD256 - for real connoisseurs.

12. BLUETOOHT - The built-in Bluetooth is not only for audio transmission, supporting various AAC, SBC, AptX, AptXHD codecs, but also allows you to control the processor settings via the Hellion DSP mobile app.

13. DRC - (Data Rate Controller) is an interface for connecting peripherals to the processor. It is used to transfer data between the processor and external devices such as DRC-LCD, VOICE CONTROL, CAN CONTROL I/O controllers, network adapters and other peripherals.

14. LINK is a technology designed to extend the functionality of audio systems. It allows two panels to be combined into a single device controlled by a single programme. This increases the number of channels from 16 to 32, which is especially useful for professional audio systems. Perfect synchronisation: No delays or glitches - everything works like clockwork.

15. PC/UAC - A USB 2.0 input is used to set up the unit with a personal computer. The port is galvanically isolated for increased reliability.

        Versatility: the modular solution opens up a new direction in car audio, allowing you to combine two panels and customise up to 32 channels.

1.         Flexible settings: the panel offers flexible settings for filters, EQ, time delays and phase rotation, allowing you to fine-tune the sound to your preferences.

2.         Lossless format support: the built-in player supports the full Lossless package including DSD-256, ensuring high quality lossless sound.

3.         Additional inputs and outputs: the panel has 6 RCA inputs, 16 high-level inputs, 10 preamp outputs, USB port for PC connection, DRC-LCD remote control input, USB audio input and control input with two configurable lines.

4. Auto Power On: automatically switch on when a signal appears on the high level input, for convenient use.

5.         Compact size: the panel dimensions are 285 x 50 x 25 mm

All in all, the interchangeable front panel with DSP provides a wide range of possibilities for car audio customisation, ensuring high sound quality and ease of use.
