Do not be fooled by the low level; even though our level 0 products do not use the technological features that our higher level products are categorised by, they still use superb quality components and are designed and constructed to a very exacting standard.
Connections Line input Eachline input is suitable for connecting to any line level music source. Line level sources include CD players, radio tuners, televisions etc.Each line input consists of a pair of RCA connectors.The M Zero has 5 line inputs available. Tape loop The tape loop is available for connecting to a cassette desk. The 'tape in' connections should be connected to the cassette deck's 'line out' and the 'tape out' connections should be connected to the cassette desk's 'line in'.
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 Zero 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.
