Reference Power Supply Design

The Reference705s employs an extremely efficient unregulated pulse-width modulated power supply. Like the rest of the REFERENCE amplifiers from Soundstream, the Reference705s is rated at 12 volts but is designed to take advantage of the additional voltage available when the vehicle is running. The two major advantages of the unregulated power supply are:

∙awesome dynamic power capabilities

∙added continuous power with higher voltages (see chart below)

Because of the dynamic properties of most music, all audio components should be able to react accordingly. Thanks to its unregulated power supply, the Reference705s can

The Soundstream REFERENCE705s amplifier has extensive internal power supply capacitance, called the Ultra- Low ESR Capacitance Bank. Multiple small input power capacitors act as an internal "stiffening capacitor". Because of the large amount of internal capacitance, there may be a sizable spark when connecting the power and ground lead to the amplifier for the first time. In order to charge the capacitor bank without a spark, we suggest you do the following:

1.Connect the +12 volt cable to the amplifier and to the battery.

2.Connect one end of the ground cable to the chassis of the vehicle.

3.We have supplied a 150 ohm, 2 watt resistor with the amplifier. One leg of the resistor has been connected to the ground terminal of the amplifier.

4.To charge the capacitor bank, touch the loose end of the ground cable to the open leg of the resistor for at least 45 seconds.

5.Remove the resistor, and connect the ground wire.
