Product details

Hypex UcD400HG HxR 1x400W Universal Class D Amplifier Module

The UcD400HG HxR amplifier is intended for a wide range of audio applications, ranging from Public Address systems to ultrahigh-fidelity replay systems for studio and home use. Hypex distinguishes their amplifiers from other class D designs due a unique circuit topology. This results in flat frequency response irrespective of load impedance, nearly frequency-independent distortion behavior and very low radiated and conducted EMI.

The Hypex UcD modules have established themselves as the new standard, both in terms of measured and subjective performance and therefore very suitable as amplifier in professional audio as well in consumer purposes.

Features

POP-free start and stop control
Differential audio input
Overcurrent and over voltage protection
No compromise components
LM4562 buffer OpAmp

I ordered the UCD400 for the third time in last two years... What surprised me this time (reason for 4 star feedback) , it looks like the PCB was assembled by garage company. From bottom side of PCB - residues from soldering - probably chemicals and what is worst - tiny balls of tin... Parts on top side - literally almost nothing in perpendicular position, coupling capacitor blocking the input conector! Does the Hypex forgot about proper module a...

I would say-everything's fine, just I expecter a bit "colder" amplifier of class D ... ;-) But in general - very good ratio "price vs. final result" ! I like the sound and construction layout of modules! And to the second question about use : It is an audio amplifier-so using it for music amplification... :-D

Exactly as described

I built a 3 channel amp with 3 of these and 3 x SMPS400A400 modules. Great clean sound, lots of detail in the the upper midrange. Only downside is the case gets very hot, almost too hot to touch. I have decent sized heat sinks on the back of each and mounted in a decent sized aluminium case with ventilation. They have not shut down yet which is what they will do if the temp is too high but I wish I could get them cooler as it currently gets ho...

Goede kwaliteit inclusief de kabels en hun afscherming. Dit model heeft niet alleen maar koelribben nodig om af te koelen. De PCB en de COIL hebben ook koeling nodig. Gebruik hiervoor ventilatoren met laag toerental, en het liefst meer dan eentje. Hoe meer Fan's, hoe lager het toerental voor dezelfde AIRFLOW. Het is een kleine uitvoering, en dat is dus waarom de warmte meer geconcentreerd is op een kleiner oppervlak.

Excellent product and fast delivery. Thankyou.

Prima product, echter het wordt nogal warm. (en dan bedoel ik niet het aluminium blok). Ik heb i.v.m. de lage behuizing een ventilator geplaatst.

These modules are pretty simple about installation and they sound amazing. Be confident on these!

By Roberto B. on 1 January 2021

very easy-to-install module, very good amplification and s/n ratio - great value-for-money - highly recommended
