The PM48/PM148 stereo power amplifier allows the use of quality home type loudspeaker with the Personal Computer soundcard. This results in a dramatic improvement in sound quality compared with the usual amplified speaker.  The amplifier connects to the sound card using a simple patch cable with 3.5mm phono plugs. The amplifier plugs directly into an unused slot in your computer. The power comes from the internal power supply of the PC, using the same connector that is used to power optional disk drives. Most PC's have plenty of power reserves in the power supply to power the amp.Two models are available, one for the older ISA slots and one for the PCI/PCIe slot, found in most desktop computers of today. Otherwise the two models are electrically the same. The PM48 has two sets of banana plugs to connect to the loudspeakers. The PM148 uses a 9-pin DSUB connector to connect to the loudspeakers and soundacrd (adapter cable is included with the PM148). The power amplifier chip is the TDA8563Q made by Philips Semiconductor. This device has internal protections against short circuits (in case the louspeaker wires get shorted) and overheating, so it is completely safe.
