Description TECHNICAL SPECS
 
Proudly made in North America, the Hafler PH34 and PH44 SUTs are passive devices that employ ultra high performance Jensen Transformers to boost the low-level signal produced by a moving coil cartridge by as much as 31dB without any amplification or the associated noise that they produce. Jensen wrote the book on transformer technology and for over 40 years has gained the accolades of being the world's most respected and revered audio transformer manufacturer.

The design begins with a 14 gauge steel casing to shield the low level signals from external magnetic fields and RF contamination. Gold-plated input and output RCA connector pairs are employed that will not tarnish over time, thus optimizing signal flow. Inside, each Jensen transformer is double shielded with heat treated (annealed) nickel composite cans and supplemented with internal Faraday shielding to deliver over 120dB of hum rejection at 60Hz. And with less than 0.05% distortion, virtually zero phase shift and a frequency response that spans 10Hz to over 100kHz, you can rest assured that the signal transfer is pure and uncoloured.

Designed to optimize the performance of any given stylus, the PH34 employs a Jensen JT-34K-DX transformer with a 1:37 turns-ratio that adds 31dB of gain for Ortofon type cartridges (5 Ohms typical) while the PH44 employs a Jensen JT-44K-DX transformer with a 1:10 turns-ratio that adds 20dB of gain for Denon type cartridges (45 Ohms typical). Since the Hafler PH34 and PH44 are designed for the purist, there are no controls. One merely connects the turntable to the SUT and sends the output signal to a standard phono input on the receiver or preamp. The Halfer SUTs quietly do the work without adding noise, distortion or artifact.

    Inside
    Jensen Transformers
    The world’s finest Jensen transformers deliver ultra-low deviation from linear phase for proper time alignment of the fundamentals and their harmonics.

    Mu-Metal
    Each transformer is fitted with double shields to block out magnetic interference from a turntable motor or nearby electromagnetic fields.

    Internal Faraday Shield
    To protect the minute signal from hum and RF interference, each Jensen transformer is equipped with an internal electrostatic shield.

    Extra Heavy Wire
    In effort to minimize signal loss from low output moving coil cartridges, extra heavy wires are employed at the input to minimize resistance.

    Twisted Wire
    Both input and output wire leads are hand wired with shortest possible wire leads and then tightly twisted to eliminate invasive radiated noise.
