  • Volume Levels

    I am using the TX-8555 with 2 pairs of JBL L830's and a Velodyne DLS 3750R sub. At a volume level of 40, the output is rather low and I have to go anywhere between 60 and 65 to get fairly loud. Is the 1) normal ? and 2)recommended ? I am under the impression that I am pushing the receiver too hard at those levels. Thanks Jim
