U series uses state-of-the-art voltage regulation technology to can get more dynamic power. 
Whether it is touring or fixed installation, U series amplifiers suit the most demanding applications due to small size, low weight, high efficiency, high power and high reliability.
In further to improve the reliability of the work of the machine, U series amplifiers are fitted with NEUTRIK, the whole series uses original Motorola semi-conductors.

The U series is equipped with state-of-the-art protection system, which includes power soft start, DC overload, short circuit, overheating, ultra-high frequency, clipping and in particular no relay output protection that has a rapid response which no relay can match.
U series amplifier can deliver sound without interruption at even high ambient temperature situations.

Excellent heat dissipation system, U series amplifiers are designed with high efficiency short-range duct double copper ribbon heat sink,
to ensure excellent heat dissipation and unmatched performance as compared to aluminium heat sinks.

The input stage of all U series amplifiers have a high sensitivity to provide ample system headroom. 
This in effect means that the input stage is almost impossible to clip. 
Built-in adjustable Voltage Peak Limiter (VPL) sets the maximum output voltage and therefore also the maximum output power. 
The sophisticated output section monitors faults and generates appropriate warnings, which are displayed on the amplifier front panel.
These alerts allow the operator to adjust system settings and thereby avoid failures.

Lloyd Lee Co. introduces two new U series amplifier models, with power output from 3400W to 7000W per channel, including a four – channel version. 
Irrespective of system size or music type, speaker systems will drive to its best performance by the new U Series amplifiers.
