Full Description

LD Systems Sound Quality

The amplifier features advanced 24 bit LD Systems DSP and offers high audio quality as well as power. Software can be downloaded to control both the DSP and Dante Networking. The free software allows you to add filters and dynamic control to perfect the sound produced, and make the amplifier sound great with a variety of speakers. A set of speaker presets is also included with the software to easily set up basic speaker applications with ease. The Amplifier also offers great transient response and 120 dB dynamic range, thanks to the high-efficiency Class H topology and switch mode power supply.

Safety and Protection

The DSP45K Power Amplifier has many safety features to ensure its longevity and protect your speakers and other equipment. To protect against strong audio signals and overloads, the amplifier features a multiband limiter, RMS speaker limiter and clip limiter, reducing the strain which will be put on loudspeakers. The Power Amp also has safety features to protect against electrical overload, such as DC, short circuit, thermal and over-current protection, whilst the power management system actively controls the current draw of the amplifier as required.
