Lab.gruppen E 5:4
The E 5:4 is the smallest amplifier in the E Series: 500 W across four flexible output channels in one rack unit. For background music zones and small paging systems it is often the entire amplifier requirement.\n\nIntelliDrive delivers 4 x 125 W on any channel into 70 V constant voltage or 2, 4, 8 and 16 ohm loads, and asymmetric loading lets the outputs differ. The amplifier carries Energy Star certification, which is the clearest statement of where the E Series puts its engineering.
