Plinius Audio SA-102

Descrizione

Caratteristiche ufficiali (in inglese):

The Plinius SA-102 Class A power amplifier is the successor to the acclaimed SA-100 power amplifier. Enhancements to the SA-102 include dual power transformers with much higher capacity than those in the SA-100, improved power supply filtering, circuit refinements, and the same energy saving and error detecting logic control as found in the SA-250.

Input configuration switching allows the SA-102 to be run as a fully balanced mono power amplifier. Two SA-102s operated in this fashion provide 460 watts per channel of pure balanced Class A music.

The SA-102 is constructed in a substantial chassis with huge Plinius designed heatsink extrusions forming the sides of the case. Enhanced cooling flow built in to the amplifier allows it to run cooler while still maintaining the substantial bias current required for Class A operation. The power supply is housed in the base of the unit and is separated from the active signal circuitry by a horizontal internal bulkhead.

Although rated at 125 watts per channel in stereo mode, the SA-102 has a very large current capacity. Difficult loads are driven with ease, although very low efficiency ones in large spaces may need the added power of the Plinius SA-250.

Input options allow for Stereo via RCA connectors, bridged mono through RCA connectors, XLR stereo via XLR balanced connectors, or XLR balanced mono. Signal carrying wires are all Siltech brand.

As with all Plinius products the SA-102 is available in both anodised black and anodised silver finishes.
