1. SPEAKER OUTPUTS 9 Two 1 4 jacks and 5 way binding post speaker output terminals are provided for each channel A Again for each channel these outputs are in parallel hence the speaker connection cables can be terminated with 1 4 phone plugs or stripped wires for use in the binding post terminals For sustained high power applications the use of the binding post terminals is recommended However care must be exercised to assure correct speaker phasing Regardless of what connections are used the typical parallel speaker load should always be limited to 2 ohms per channel or 4 ohms Bridge mode for any application Operation at loads of 4 ohms per channel or 8 ohms Bridge mode is more desirable for sustained operation applications due to the fact that the amplifier will run much cooler at this load Operation above 4 ohms per channel and even open circuit conditions can always be consid ered safe However sustained operation at loads below 2 ohms could result in temporary amplifier shutdown due to the thermal limits and or the amplifier internal fault circuitry AC LINE CORD 120 V products only 10 All the PV Series power amplifiers are fitted with a single heavy duty 3 conductor line cord and a A conventional AC plug with a ground pin It should be connected to an independent circuit capable of supporting at least 15 amps or greater continuously This is particularly critical for sustained high power applications If the socket used2.
