      Inputs and Outputs

      Audio

      • Phono Input: There is an MM phono input on Onkyo TX-NR686 and Yamaha RX-A780 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
      • Analog Pre-Outs: Yamaha RX-A780 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 7 channel processing but have only 7 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 7 pair of line inputs on Onkyo TX-NR686 and 4 pair of line inputs on Yamaha RX-A780 for connecting sources with analog outputs.
      • Digital Inputs: 2 optical inputs and 1 coaxial input are available on Onkyo TX-NR686 and 2 optical inputs and 2 coaxial inputs are available on Yamaha RX-A780 for digital audio connections.
      • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
