AVM PH 30.3
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 phono preamplifiers have regularly won awards and reference titles worldwide. They continuously test, fathom and refine the tonal performance in countless listening sessions and as a result present the PH 30.3, a completely new phono preamplifier.
The sensitive smallest signal amplifiers for RIAA pre-equalization require very special attention, because in the entire audio chain the very smallest electrical signals are processed here, often only a few µV (10-6 volts). The tiniest errors have a big impact, and the most careful signal processing has a particularly extensive effect on the sound. In addition, with our ROTATION turntable and with our own AVM.3 Cadenza MC cartridges (made by Ortofon) also highly performant cartridges in house.
From this you can already guess what tremendous care the development team with trained ears used to build a sonically excellent phono preamplifier, which can also be combined with high end components at the very highest level. AVM has not only built up decades of tried-and-tested know-how in this area, which is valued worldwide – our manufacturing methods also ensure extremely precise production quality in series production.
The PH 30.3 is suitable for amplifying the smallest signals from MC and optionally MM systems. Separate connections are available for this purpose. The DIP switches, which are insufficient in terms of sound quality, have been deliberately omitted. To be able to ideally adapt the MC pickup system of your choice to the PH 30.3, 100/200/1000Ω load adapters are included.
These load adapters are also equipped with gold-plated connectors and are thus effectively protected against aging processes (e.g. corrosion due to humidity). Which value is recommended for your system, please refer to the documentation of your pickup system or ask the manufacturer. Phono load adapters are plugged into the designated jacks in parallel with the MC systems.
Special features of the PH 30.3
In the PH 30.3, AVM relies on sound-optimized circuits from its repertoire and borrows from the current OVATION Line phono preamplifiers. They have paid special attention to shortening the signal paths up 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 P1.2 and P30, they now also set completely newly developed amplification circuits and use novel, exquisite and finely selected amplification components. The layout was developed in state-of-the-art CAD design systems and the signal path could be shortened by almost 80%.
The making of
The solid aluminum housing made of a thick extruded profile, made exclusively for AVM, effectively protects the special board from external mechanical influences and microphonic effects.
