LMS-408

The Ahuja LMS‑408 Loudspeaker Management System is a professional‑grade audio processor designed to give sound engineers detailed control over complex PA systems. It features a 4 input and 8 output architecture, making it suitable for managing multiple speaker zones, subwoofers, and full‑range cabinets in live sound reinforcement, concert setups, installations, and touring applications.

At its core, the LMS‑408 uses 32‑bit digital signal processing (DSP) with a high‑resolution 48 kHz sampling rate and 24‑bit AD/DA converters, ensuring clean, transparent audio with low noise and distortion. Each input channel offers adjustable settings such as high‑cut/low‑cut filters, 5‑band parametric equalization (PEQ), noise gate, gain, mute, phase, and link control, giving you flexible tonal shaping and signal conditioning.

On the output side, the unit provides precise control over crossover points, 7‑band PEQ, gain, mute, compressor/limiter, phase, delay (up to 680 ms), and channel linking. Filter types include Butterworth, Linkwitz‑Riley, and Bessel with selectable slopes from 6 dB to 48 dB per octave, allowing detailed tuning of your sound system to match room acoustics and speaker configuration.

Additional features include a channel matrix selector, adjustable preset copying, built‑in signal generator (white noise, pink noise, sine wave), and a dot‑matrix display for clear parameter viewing. With balanced XLR inputs and outputs and robust professional design, the LMS‑408 is an essential tool for achieving controlled, high‑quality audio in demanding live and installed sound environments.
