MANNVS II
Balanced MM Interface System

Integrated architecture for MM/MI signal transfer.

MANNVS II combines transformer coupling and impedance control within a single interface stage.

Signal transfer and electrical interaction are defined together.

A broadband transformer (1:2) provides controlled coupling, moderate voltage gain (+6 dB) and conversion to a floating balanced output.

A parallel LR network defines frequency-dependent loading and cartridge–stage interaction.

Galvanic isolation is maintained between input and output, reducing sensitivity to grounding conditions.

Single-ended input.
True balanced XLR output.

Designed for systems requiring precise MM interface control and integration into fully balanced signal chains.

       

QVATTVOR Classic

True Balanced MC Step-Up Transformer — Heritage Implementation

A structured expression of the Heritage approach.

QVATTVOR Classic extends signal continuity into a fully balanced architecture.

Matched transformer pairs define a stable and coherent magnetic field, while preserving the natural flow of the cartridge.

Signal behaviour is not simplified, it is stabilized.

The system remains continuous, but gains structure, separation, and spatial control.

QVATTVOR Classic is not about minimal intervention.

It is about maintaining musical continuity within a defined and repeatable structure.

       

EQVES Model 1

Single-Ended MC Step-Up Transformer / Heritage Implementation

The most direct expression of the Heritage approach.

EQVES preserves signal continuity through a minimal magnetic topology and a shortened signal path.

No differential structure.
No additional signal organization.

The transformer remains closely coupled to the cartridge, allowing the system to behave as a single continuous structure.

The result is immediate, coherent signal flow with minimal structural intervention.

EQVES is not about control.

It is about preserving the natural behaviour of the cartridge within the system.

       

fonolab Dual-Approach Step-Up Architecture

ENGINEERING SERIES

Designed for defined and repeatable signal behavior.

Transformer operation is fixed by design:
– defined winding structure
– controlled coupling
– stable reference conditions

User control is limited to a single parameter: pass or alternative load resistance - following cartridge recommendations.

This does not change the architecture.

It ensures correct electrical matching.

The result is consistent, predictable performance across systems.

No tuning.

No variability.

Just controlled, repeatable behavior.
