The ART SLA 2 is a true linear amplifier ideal for powering passive speakers. Featuring Euroblock connectors as well as two XLR & TRS inputs & binding post outputs you can choose to bridge channels one & two. This means that you can enter either stereo mode or bridged mono amplifier mode that delivers the full power in a single 8 Ohm load. Safe from short circuits & overloading the SLA 2 features an ultrasonic network that decouples the RF from the output. Even with low impedance the SLA 2 is stable supporting 4 Ohm loads. Linear amplifiers require a considerable amount of power to operate because of this they generate heat that can lead to problems. The SLA 2 utilises a Smart Fan cooling system that measures its ambient temperature & adjusts itself accordingly to lower it to an optimal operating temperature. On the front of the SLA 2 are two pop-up gain knobs that you can use to attenuate the level of each channel you can cover these with an included anti-tamper faceplate once tuned to your equipment. Powered By an IEC cable & taking up only 1U of rack space the ART SLA 2 is an essential unit for any passive speaker system.
