HYPEX UCD700LZ Amplifier Module

The Hypex UcD700LZ is a Class D amplification module designed for applications requiring high power into low-impedance loads. Its LZ design, for Low Impedance, increases the current capacity compared to standard UcD modules, allowing it to deliver up to 1200W into 2Ω while maintaining a reduced output impedance and a load-independent frequency response.

Hypex UcD700LZ: Amplification architecture

The module features a fully passive control loop, combined with a linear frequency response that is independent of the speaker impedance. This architecture limits total harmonic distortion across the entire spectrum, while the low noise level preserves the clarity of the signal in high-efficiency systems. The differential audio input and the buffered input stage facilitate its integration into multichannel electronics or an active speaker.

Hypex UcD700LZ: Integration and control

The UcD700LZ operates from unregulated power supply rails and integrates noise-free start-up and shut-down control, preventing "pop" phenomena when powering on or off. This design allows its integration into power amplifiers, active speakers or professional systems where low-impedance stability is a priority design parameter.

Hypex UcD700LZ: Built-in protections

To ensure safe operation under demanding load conditions, the module monitors temperature, current and supply voltage. It also integrates DC fault detection as well as short-circuit protection, reducing the risk of damage during an overload or an electrical fault.

Hypex UcD700LZ: Applications

The Hypex UcD700LZ is suitable for building active speakers, domestic or professional power amplifiers, Line Array systems, immersive installations and home cinema configurations. Its ability to deliver high current into low impedance also makes it suitable for multichannel amplifiers and systems requiring sustained power into difficult loads.
