OEM PreAmplifier
Product information "OEM PreAmplifier"
The Hypex OEM PreAmplifier Module offers a fully analog, high-fidelity PreAmplification stage, engineered for easy integration into a wide range of audio products. Designed for maximum signal integrity and operational flexibility, it delivers an unparalleled user experience combined with best-in-class reliability.
At its core, a 2.7” monochrome display with adjustable brightness and an energy-saving on-time standby mode optimises both functionality and aesthetics. Control is intuitive, using two precision-machined aluminium rotary encoders, complemented by remote-control functionality for added convenience.
The module supports multiple analog and digital inputs, each with individually adjustable gain offset, ensuring perfect source matching. Internal digital control manages input selection, volume, and system standby.
SIZE AND WEIGHT
Al modules of the OEM PreAmplifier, including the FusionConnect Add-on, are designed to fit in a 435 mm wide Hi-Fi enclosure and are also compatible with a 19” rack space.
DAC Performace data
All audio measurements are done with AES17 20kHz filter and no weighting.

Recommended additional products
The FusionConnect add on enables digital integration between the Hypex OEM PreAmplifier and Fusion-Amp products. It provides a digital connection that forwards both digital and analogue input signals from the preamplifier to the connected amplifiers. Analogue input signals are converted internaly using an integrated analogue to digital converter before transmission. This conversion stage is intended to provide consistent signal quality when distributing analogue sources to FusionAmp based systems. FusionConnect interfaces directly with the OEM PreAmplifier Module via a dedicated expansion connector. The add on is supplied as a modular PCB for direct integration and does not require additional external control or configuration. The FusionConnect add on is intended for system designs that require centralised input handling and digital signal distribution between a preamplifier and multiple amplifier modules.
