LD Systems AMP 205

LD Systems AMP 205 - Power amplifier with 2 channels, Class D, power of 2x50W at 4 Ohm, featuring passive cooling and high efficiency. The front panel offers LEDs for signal, clip, and protection, while a gain switch allows compatibility with various audio sources.

With an ultra-compact format and included mounting plates, it can be discreetly installed under tables or behind screens. It can also be mounted in a 1/3 19” rack, and with an optional tray, up to four products from the TICA® series can be combined.

It has remote control for integration with external control systems: volume adjustment on each channel or activation of standby mode. The optional auto-standby function reduces power consumption in the absence of audio signal.

Connections are easily made via terminals for balanced line inputs and outputs for speakers, making this amplifier an ideal solution for professional audio installations.
