    The widest musical dynamics • In the L-10000, there is no coupling device between the preamplifier and the power amplifier; that is, the final gain/output tubes are directly connected to the power amplifier. Thus, the benefits listed above are fully present in the Allnic L-10000 preamplifier.

If the gain stages are set up and functioning properly, the needles of the meters should be in the centre between the two parallel lines in the middle of each meter.
