The LD Systems AMP 405 is a professional class-D mini amplifier designed for 4 channels.

The LD Systems AMP 405 is a professional class-D mini amplifier designed for 4 channels. It delivers 4 x 50W at 4 Ohms and 2 x 100W at 2 Ohms. The amplifier features a tabletop form factor with optional rack-mounting hardware. It supports load impedances of 2 and 4 Ohms. With a power rating of 2x 100 W RMS at 2 Ohms and 4x 50 W RMS at 4 Ohms, this amplifier is built for reliability. The unit includes protections against DC fault, overvoltage, short circuit, thermal, and undervoltage.

It offers a frequency response of 20 Hz to 20 kHz and a SNR of greater than 100 dBA. The distortion level is less than or equal to 0.02% THD+N at -6 dBu, 20 kHz bandwidth. A 24-bit DSP at 48 kHz is included, along with adjustable audio delay up to 2 ms per channel. Analog audio inputs include 2x block 4-pin speaker outputs and 4x block 3-pin line inputs.
