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.
