        10. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Pioneer SC-LX501 and Pioneer VSX-LX503 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Pioneer VSX-LX503 has 11.2 preamplifier outputs which allows you to connect the receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, Pioneer VSX-LX503 has 11 channel processing but has only 7 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
        • Analog Line Inputs: There are 4 pair of line inputs on both receivers for connecting sources with analog outputs.
        • Digital Inputs: 2 optical inputs and 1 coaxial input are available for digital audio connections on both receivers.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
