The DEQX Pre-8 is an advanced HD-Active preamp processor designed for high-end audio systems, particularly for those using active speakers.1 It serves as a central hub for your audio setup, combining multiple functionalities into a single, state-of-the-art chassis.
 
 
Key Features and Capabilities
 
All-in-One Preamp Processor: The Pre-8 integrates a high-quality preamp, DAC (Digital-to-Analog Converter), ADC (Analog-to-Digital Converter), and a streamer with Bluetooth and network connectivity.2
 
DEQX HD-Active Crossover: It includes the DEQX-HD-Active linear phase crossovers, which can handle up to a stereo 4-way active system. This allows for precise digital crossover settings and provides digital outputs for all channels.
Speaker and Room Correction: A key feature of the Pre-8 is its ability to correct your speakers' native impulse response errors and then perform room correction.3 It uses precise measurements of each speaker to create a correction filter that restores amplitude and time coherence, and then corrects for acoustic modes and resonances in the listening room.
 
High-Performance Components: The unit is built with high-quality components, including an ESS Sabre Pro ADC and DAC, a hexacore ARM processor for enhanced processing power, and ultra-low noise power supplies.4
 
Modern Usability: It features a 5.5-inch HD touch-sensitive AMOLED display, a large volume control, and a web browser-based UI for cross-platform, zero-install speaker calibration and room correction via the new DEQX Cloud.5
 
Comprehensive Connectivity: The Pre-8 offers a wide range of inputs and outputs, including balanced XLR and unbalanced RCA analog inputs and outputs, multiple digital inputs (USB-B, optical, coaxial, AES-EBU), and digital outputs for each speaker channel. An optional Dynavector phono preamp module is also available.
 
The DEQX Pre-8 is a solution for audiophiles seeking to achieve a truly transparent and realistic audio experience by addressing the performance limitations of both their speakers and their listening environment.
