The A4 amplifier is the result of a five year collaboration between Funktion One and leading audio electronics specialists XTA to produce a sonically excellent and reliable amplifier module. It is a 2 channel Class-D/T Power Amplifier with power provided from a Switching Power Supply. It is fully self protected and fan-cooled and gives exceptional power, remarkable clarity and all from a 3.2kg package. The module also includes renowned XTA 96kHz DSP for plug and play simplicity meaning that a product like the Resolution 2A or Resolution 4EA-CP can be simply operated from a full range signal input. Furthermore, there is enough power present to drive an unpowered slave enclosure.
