  • Notes

  • The Pioneer A307R integrated amplifier benefits from Pioneers' Direct Energy MOSFET transistor design which is linked directly to the speaker outputs. This efficient design of the Direct Energy MOSFET allows Pioneer to develop an advanced direct connection, a shorter signal path, and ground line combined with its internal symmetrical construction makes sure that the left and right channels are separated giving the best possible stereo reproduction for an amplifier of this price.

    The Pioneer A307R also features speaker switching which means that you can run 2 sets of speakers from one amplifier, so if you would like another set of speakers in another room without the need for a whole other system all you need to do is press the speaker A/B button and your music will come through in your second room.
