Unpacking and installation Please ensure care is taken when unpacking the pre-amplifier. We recommend that you store the packing materials in case the unit requires shipping at a later date. Also, check that no transit damage has occurred before installing the pre-amplifier. Select a suitable location for the unit, ensuring that adequate ventilation is provided as the pre-amplifier generates considerable heat during normal operation.
Operation Once all the connections are completed and checked, make sure all power amplifiers are off and flip the mains rocker switch located on the back panel of the pre-amplifier to the 'on' position. The M One is a vacuum tube design and therefore requires about 45 seconds warm-up time. After this the remaining system components may now be turned on. In order to use the line inputs, select 'source' and the appropriate input.
