When you are programming levels the integrated amplifier operates as a preamplifier with a fixed volume setting equivalent to 65. This level is chosen to be comfortably loud on average sources. You can switch between sources and adjust the relevant input levels to achieve the setting you want. The display will show: Customising the integrated amplifier To balance input levels q Turn off the integrated amplifier, using the power switch on the back panel. q Turn on the power again while holding down the Mute key on the front panel.
