Overview

Hypex Direct PreAmplifier Kit

PreAmplifier Kit

Gain Up, Noise Down

The PreAmplifier Kit is loaded with features created to deliver a high-quality audio and user experience. At its core is a fully analog PreAmplifier design, managed through a 2.7" monochrome display with adjustable brightness and an on-time standby function. A power LED provides clear status indication, while two solid aluminum control knobs offer precise adjustment and add a satisfying tactile element to your system. For added ease of use, the kit also includes a remote control so you can make adjustments from across the room.

Each input on the PreAmplifier includes adjustable gain offset, allowing you to tailor audio levels to better suit your preferences. The kit can also be expanded with the PreDIGin Add-on, adding a DAC, Fusion Connect board, Bluetooth input board, and streaming capability.

One of the most appealing aspects of the PreAmplifier Kit is the way it combines high-end quality with the hands-on satisfaction of a DIY build. Putting the amplifier together not only gives you a rewarding sense of accomplishment, but also offers a better understanding of the technology behind your audio gear. The kit is designed to be approachable, with clear instructions that walk you through the assembly process. Most users can complete the build in less than an hour, making it a manageable project even for those new to DIY electronics. An online instructional video is also available for extra support, providing a visual step-by-step guide to help the process go smoothly.

The PreAmplifier Kit has a clean, modern look with a matte black finish that complements a wide range of audio systems. Its enclosure is made from durable, high-grade aluminum, giving it the strength to handle regular use while keeping its appearance intact. This solid construction helps the preamplifier deliver reliable performance while maintaining its visual appeal over time.

Product Applications

Hypex Direct products can be used in a wide range of DIY applications. Explore the different examples within each application category to help find the right solution for your project.

Preamplifiers

A preamplifier boosts low-level signals up to line level, which is the standard operating level required by your power amplifier. That means a preamp is needed for nearly any audio source. In addition to raising low-level signals, a preamplifier also manages source switching and volume control for line-level inputs.

Mono Power Amplifier

A mono power amplifier is a self-contained single-channel amplifier unit with its own dedicated power supply and matched amplifier section. Mono power amps are often regarded as one of the best ways to build a high-quality amplifier system. They are commonly used in Hi-Fi and high-end audio systems, but they can also serve in musical instrument amplifier applications.

Stereo / Dual Power Amplifier

A dual power amplifier contains two power supplies and two amplifier channels, with each channel running from its own dedicated power supply. Both the power supplies and amplifier sections are housed within a single enclosure. A stereo power amplifier uses one power supply to run two amplifier channels within the same enclosure.

Multi Channel Amplifier & Immersive Audio

A multichannel amplifier houses multiple amplifier channels within a single enclosure. Common multichannel designs include 4, 8, 16, or even 24 channels. Most use a single power supply, though some models may include two or more power supplies depending on the number of channels and the power demands.
