The Urei LA-5 Audio Leveller has been finely tuned to serve as the perfect solution for safeguarding amplifiers and speakers from power overload. It accomplishes this by detecting the incoming signal and controlling the level, effectively limiting the output power to a safe, predetermined value set by the operator or installer, regardless of the input signal’s amplitude.
One of the significant advantages of the Urei LA-5 is its ability to alleviate the challenges faced by live sound mixers. Often, they grapple with the task of compensating for inconsistent microphone technique and wide dynamic ranges encountered during live performances. The Urei LA-5 steps in to alleviate this burden.
The patented detection and gain control technology employed in the Urei LA-5 align with how our auditory system perceives sound. This design choice results in exceptionally smooth control, setting it apart from conventional peak limiters.
Furthermore, the Urei LA-5 offers balanced inputs and outputs, although it can also function with single-ended connections. With high input impedance and low output impedance, it provides maximum flexibility for patching and interfacing with various audio setups.
Recent advancements in integrated circuits have further improved the LA-5’s performance, delivering an enhanced signal-to-noise ratio compared to earlier designs. This translates into cleaner and more precise audio processing.
However, it’s worth noting that the Urei LA-5’s gain reduction circuitry operates on an RMS (Root Mean Square) basis. As a result, it is not recommended for overmodulation protection in applications such as broadcast transmitters, disc or optical recorders, unless it is followed by a peak limiter like the Urei 1176 LN.
The Urei LA-5 Audio Leveller is a specialised tool tailored for sound reinforcement professionals, offering a unique combination of power overload protection, smooth control, and compatibility with a variety of audio systems, all while adhering to principles grounded in the perception of sound.
