H-5000 DHT Phono Stage

 KEY FEATURES

LCR TYPE RIAA EQUALIZATION - RIAA equalization is a specification for the correct playback of vinyl records, established by the Recording Industry Association of America. The purpose of the equalization is to permit longer playback times and improve sound quality.

RIAA equalization is a form of establishing a flat frequency response for the playback of recorded music. The necessity for this equalization process arises from mechanical difficulties inherent in record production. In order to prevent the cutting needle from over‐cutting into the next record groove in the bass, as a record is cut, some bass frequencies are attenuated. In the treble region, in order for high frequency sounds not to be masked by the noise inherent in moving a stylus over and through a modulated vinyl surface, some treble frequencies are boosted. With the application of the correct filtering techniques on playback, the result is a flat frequency response with better signal to noise ratios.

The H-5000 is equipped with newly developed Allnic “Multi-Curve” LCR units (one for each channel) which have four (4) Turn-overs (frequency options) and four (4) Roll-offs (gain reductions in dB). These new units provide for the reproduction of various recording curves (both for bass attenuation and treble boost) used by different companies prior to the establishment of the RIAA standard. There are 4 Turn-over options, at: 250Hz, 400Hz, 500Hz RIAA and 700Hz. There are 4 Roll-off options (at 10KHz): -5dB, -11dB, -13.7dB RIAA and -16dB.

 

In addition, the H-5000 also has the following features:

• The H-5000 Phono-stage is transformer coupled, with the exception of the first gain stage, the HL-2 tube.

• No negative feedback design with three gain stages

• A power supply unit separate from the pure DHT phono-stage itself

• High quality MC Step-up Transformers with Permalloy cores are used for the H-5000’s dual MC inputs.

• New vacuum tube damping technology – Allnic Audio’s patented "Absorb GEL tube damper" technology prevents harmful vibrations from reaching the signal / gain tubes and, therefore, prevents micro-phonic noise propagation in the tubes. The Allnic Audio Absorb Gel damper technology effectively solves a problem that plagues most tube amplification systems. Provided other tube components do not introduce micro-phonic noise into your system, with the Absorb Gel damping system, you will enjoy a degree of transparent sound that will surprise and please you.

• Pure Class A operation

• Pure balanced operation

• As are all Allnic Audio products, the H-5000 is fully RoHS (EU Reduction of Hazardous Substances regulation) compliant in construction and materials.
