The PH 8.3 at a glance

– Tube phono preamplifier with up to 4 inputs (as optional plug-in modules)
– Available plug-in modules: MC XLR (balanced), MC RCA, MM RCA
– All settings can be remote controlled (gain, equalization curve, phase, load etc.)
– Five separate power supplies: Main power supplies for + & – voltages (separated), power supply for processor unit, power supply with high voltage generation for tube stage, high-performance power supply for use with turntables of the AVM ROTATION series
– Fully DC-coupled (depending on selected settings)
– Analogue and purely passive equalization of incoming phono signals
– Extensive menu functions (adjustable input sensitivity, peak power, etc.)
– Stand-by consumption <0.5W
– Mains phase display (LED off = mains phase OK)
– Large, blue illuminated graphic display
– Housing variants: Aluminum silver or black, chrome front optional
– Packaging: Sturdy AVM OVATION Flight Case

Pickups for vinyl players always require an additional amplification stage. In order to push the sonic possibilities of analog vinyl to the very limit of what is feasible, AVM has developed an audiophile phono preamplifier with a multitude of extensive features. With the OVATION PH 8.3 phono preamplifier, adjustments can be made comfortably from the listening position to ideally reproduce different pickup systems, arms and vinyl players. As with all models of the OVATION 8 series, the output stage is an original OVATION tube stage with exclusive AVM 803 T tube technology and its unmistakably charming tube sound.

Maximum comfort and comparability: With the PH 8.3 phono preamplifier all common adjustments of a pickup system (MM/MC) can be made and much more! Personal custom settings such as gain, load, mono/stereo, equalization curve and subsonic filter can be conveniently set and stored via remote control. This makes it very easy to compare different tone arms and pickup systems even without leaving your ideal listening position.

The PH 8.3 provides a perfectly adjusted power supply for our own turntables of the ROTATION Series .

The technology behind

The PH 8.3 equalizes the phono signals purely passively and analogously and not in an amplifier stage. This has the advantage that each of the three time constants can be set individually. This makes it possible to use 5 other common LP equalizations (RIAA, TELDEC, NARTB, EMI, COLUMBIA, DECCA) in addition to the RIAA curve that is widespread today. These curves differ in the corner frequencies & time constants used when cutting the record. These separation characteristics are inverted by the PH 8.3 with an accuracy better than +/- 0.1 dB. We achieve this extreme accuracy through the complex matching procedure of the built-in resistors (matched to 0.1%) and the film capacitors (matched to 0.5%).

With the switchable subsonic filter, rumbling noises can be effectively dampened (30Hz/12dB/octave).

The level (gain) can be adjusted in 5dB steps to measure different pick-up systems. Mono/stereo and the phase can also be inverted for the best sound measurement and for older recordings. All adjustments or settings can be conveniently made from the listening position using the remote control supplied and are also saved automatically.

On the input plug-in cards, the incoming signals are amplified immediately after the input at line level (approx. to 150mV), with MM by 40dB, with MC by 60dB. All equalization or adjustments are then made with these greatly enlarged signals, so the distortion components of all subsequent stages are far less important in comparison. Up to 4 different inputs can be equipped as desired, so any combination can be selected from the following input modules: MC XLR (balanced), MC RCA, MM RCA. The PH 8.3 automatically recognizes which modules are plugged into which slots or as combinations and adapts all functions such as the menu structures. The inputs can also be named individually. Inputs are galvanically isolated from each other.

The effort is also immense for the power supply: 5 independent power supply units supply all stages of the PH 8.3 individually and effectively prevent other components from mutually influencing the amplifier stages. The silent switching power supplies deliver high-precision supply voltages, practically independent of the mains voltage. In contrast to large transformer power supplies, no acoustically negative magnetic fields are generated with these power supplies.
