The F5 studio monitor is the model that started it all for Fluid Audio. Fluid Audio's remarkably affordable F5 monitor brings a lot of technology and value to the table. The amplifier rear panel has not only XLR and TRS inputs for more professional applications, we have also included an RCA input for more "consumer friendly" applications. The amplifier has a generous heat sink for long mixing sessions. Most monitors have their amp heat sinks inside the cabinet where all the heat is generated and cannot escape. The F5 amplifier ICs are mounted directly to the heat sink, so heat can transmit harmlessly away from the drivers and internal circuitry. The amp also has something no other monitor in its class can boast - A standby circuit that shuts down the amp after 20 mins of non use. Color: White.
