AVM - PH 30.3 Phono Stage - MM & MC Preamplifier

AVM - PH 30.3 Phono Stage - MM & MC Preamplifier

Already since the founding year 1986, the development and manufacture of phono preamplifiers are always the center of attention at AVM. For several decades now, the AVM phono preamplifiers have regularly won awards and reference titles worldwide. In countless listening sessions, we continuously test, fathom and refine the sonic performance and, as a result, present the PH 30.3, a completely new phono preamplifier.

The PH 30.3 is a versatile, stand-alone phono stage usable with the A 30.3 integrated, or any line stage preamplifier. Phono cartridges produce very low-level signals, and the PH 30.3’s heavy extruded aluminum chassis provides optimal shielding, and the circuit’s ultra-short signal path further guarantees that the precious music signal will remain pure, and free of noise or interference. An external power supply also aids in protecting the equalization circuitry from EMI.

The unit can provide stunning sound quality from either MC or MM cartridges; separate inputs are provided for both types, with operational mode selected by a back-panel switch. Plug-in load adapters can be used to provide optimal matching for MC cartridges and will remain stable over time, unlike commonly-used DIP switches. The PH 30.3 also pairs perfectly with either model AVM Rotation turntable, and its brushed finish matches other 30.3 series components.

Special features of the PH 30.3

In the PH 30.3, AVM relies on sound-optimized circuits from AVM's repertoire and borrow from the current phono preamplifiers of the OVATION Line. AVM has paid special attention to shortening the signal paths to the first amplification stage in order to ideally protect the smallest signals to be processed from electromagnetic interference. In contrast to the two predecessors P 1.2 and P 30, AVM now also use completely newly developed amplification circuits and employ new, exquisite and finely selected amplification components. The layout was developed in AVM's state-of-the-art CAD design systems and the signal path could be shortened by almost 80%.

The making of

The solid aluminum chassis made of a thick extruded profile, made exclusively for AVM, effectively protects the special board from external mechanical influences and microphonic effects. Extensive quality control, which ensures our manufacturing standards is, as always, a matter of course for AVM.
