InstallationHeat power calculationIf a 4 Ω load is connected to each output channel of the LA8, each channel delivers up to 1800 W.With a standard use at 1/8 of full power (9 dB headroom), the power delivered per channel is:1800 / 8 = 225 W, so a total power of 4 x 225 = 900 W.According to the table in section Power consumption (p.20), the LA8 power consumption is 1500 W. The heat powerproduced is then (difference between power consumption and output power):1500 - 900 = 600 WAudio and network cablingConnection panelsThe amplied controller's rear side features three panels for audio and network cabling:— a speaker panel (1) to connect the loudspeakers— a signal panel (2) to connect the analog and/or digital (AES/EBU or S/PDIF) audio sources and link the signals toanother amplied controller— an L-NET panel (3) to connect to a network and be remotely controlled by LA Network ManagerLA8 audio and network connection panels1 2 3Speaker panelThe two 4-point SpeakON connectors and the 8-point CA-COM connector on the rear panel are for loudspeakerconnection.
