DESCRIPTION 4 channel 240W RMS power amplifier focused on applications for public address systems and professional audio. The use of digital signal processors as well as Class-D power amplifiers represent a technological advancement and a substantial increase in its performance. The equipment includes two power supply inputs: the main one for 110-230 VAC and an input for batteries (24 VDC). This enables the possibility of keeping the equipment operative during power cuts of the main AC input. It includes an electronic protection system against overcharge, short circuits and excessive heating. Besides, it includes an energy savings system (STANDBY mode) that automatically activates 30 seconds after detecting a lack of an input signal. Both its mechanic and electronic design are based on functionality, robustness and reliability criteria required for any sound application. Thanks to its standard dimensions (19'' standard, 1U), the equipment can be associated with UDE equipment and other elements such as audio sources, preamplifiers; among others. As a result we obtain a compact and uniform set with an important space-saving design. Its forced horizontal ventilation system allows it to be assembled in a rack by using its integrated mounting brackets.

HIGH PASS FILTER:
STANDBY: ON Mode: The amplifier never enters Standby mode. It is always operative. OFF Mode: The amplifier enters Standby mode when it is switched on and exits once an input signal is detected. If during 30 seconds no signal is detected on the input, the amplifier enters Standby mode. HIGH PASS FILTER: ON Mode: Filter disabled. OFF Mode: Filter enabled.
