        7. Speaker Configurations

        Marantz NR1508's and Pioneer VSX-831's amplifiers can be assigned for different speaker configurations.

        • Configurations: Available configurations are:
        • Marantz NR1508: 5.2 with internal amplifier.
        • Pioneer VSX-831: 5.2 with internal amplifier.
        • Bi-Amp: Pioneer VSX-831 is able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

        9. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Pioneer VSX-831 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Marantz NR1508 has 2.2 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, both receivers have 5 channel processing but have only 5 channel amplifiers, so they need external amplifiers connected to the analog pre-outs in order to reach their maximum speaker configurations.
        • Analog Line Inputs: There are 3 pair of line inputs on both receivers for connecting sources with analog outputs.
        • Digital Inputs: 1 optical input 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.
