the preamplifier Five analog input pairs are provided for use with balanced (2 pr. XLR) and
The overall gain for the preamplifier section may be adjusted to optimize performance with each input, easily accommodating unusually high- and low- line level source components within the same system. This degree of optimization was first offered in the Nº32 Reference Preamplifier.

the volume control Precision electronic control of analog volume has been a standard feature of Mark Levinson preamplifiers for nearly a decade. Dual solid- state stepped attenuators offer precision attenuation of balanced analog signals. Local supply regulation and passive bypass components are
8used to assure optimum results. As with so many of the individual component parts used in Mark Levinson products, selections were based on extensive listening tests. As it has always been, carefully controlled listening tests are crucial to the design process at Madrigal.
the power amplifier The Nº383 output stage uses the same devices (12 per channel) as the Mark Levinson
The large output capability of this amplifier required that proper cooling be a consideration in the design. Output transistors are widely spaced along the current gain circuit board in order to facilitate heat dissipation. Ventilation is provided by custom heatsink extrusions mounted on the sides of the chassis.
protection Protection from internal or external component failure is an integral feature of the Mark Levinson design philosophy. The Nº383 employs several forms of protection, both for its own
