PH 53 is a state of the art phono amplifier. The unique balanced current injection input for a wide range of MC cartridge and LEF amplifier technology for the output stage provide todays top level sound quality. Also standard RCA input for unbalanced use with MM or MC cartridge is available. All amplifier sections run without any overall negative feedback. Thus the amplifier creates no dynamic distortions.
PH 53 is compatible with both MM and MC cartridges and allows precise settings with DIP switches on its bottom panel. Input capacity for MM cartridge is adjustable to around 47pF to 884pF with 4 switches per channel in addtion to cable capacitance. Also input impedance is ajustable to 100Ω that is a coomon value for most MC cartridges or to 1Ω that is a standard value for most high output MC cartridges. Input Impedance for MM cartridges is fixed at 47Ω with all the switches open. Gain switches are also applied increasing the gain by 6 dB for low MM and high MC, or 20dB for low MC.
• Inputs include jacks for XLR balanced current injection or unbalanced RCA. Output signals are always available balanced and unbalanced, regardless of the input.
• Always us one input only!
State of the art Current Injection technology.
Current Injection is a landmark technology for shortening the signal path, improving the sound quality and measurement specs significantly. The effective simplicity of Current Injection requires a non feedback loop amplifier, LEF gurantees best performance of the current amplifier with low THD. Both technologies complement each other and overcome the limitations of traditional circuitry to a better standard of music reproduction. this is applicable when using balanced MC input. The maximum performance of MC cartridges is attained because neither a redundant amplification stage non negative feedback are present in this method, and an outstanding capability for musical expression is achieved without sacrificing measurement specs.
• Not applicable for RCA input.
CEC`s unique LEF circuit
PH 53 features CEC`s unique LEF (Load Effect Free) circuit that virtually eliminates the causes of musical degradation. High efficiency is achieved with this LEF circuit along with the acquisition of delicate, subtle sound reproduction. The music reproduction appeals to the senses, forgetting about a performance of technical equipment. The orginal sound is reproduced in highest fidelity.
PH 53 uses RIAA equalization with Neumann extension. The Neumann time constant or some equivalent is used on almost all recordings. RIAA with Neumann extension allows a wider top frequency extension. According to RIAA the frequency response drop from 20kHz on. Beyond 20 kHz the Neumann character shows a gradual decline and the flat.
PH 53 also has a subsonic filter for preventing large woofer excursions and muddiness in midrange due to mechanical vibration noise signals that are found below 15Hz. You can select from two different downward curves, soft and maximum reduction.
