Phasemation T-1000 Monoaural MC Step-Up Transformer

Adopted a tough chassis structure with 2 unit boxes of independent Lch and Rch and completely monaural. Like the T-2000 which is the top MC step-up transformer, by having it as a monaural unit box separating the Lch and Rch completely, we thoroughly eliminated the sound interference of the left and right.

 

When generating power through a cartridge coil, a balanced operation is conducted essentially. Transmitting this signal with an unbalanced connection results in not only losing the merit of a balanced type, but also external noises directly effects the sound quality.

 

The basis of wiring connections by using a balanced phono cable is shown in Fig. 1. The signal is transmitted from the cartridge coil to the transformer coil through the push-pull balancing circuit and the shield earth covers them. Therefore, the effects caused by external noises can be blocked. In addition, the full balanced connection (No.2 pin hot) is structured for the cartridge side by connecting the center of the input part of the transformer to the signal GND of the output part.

 

A general structure of connecting a step-up transformer for MC cartridge to an unbalanced phono cable is shown in Fig. 2. At the unbalanced connection composed of the signal wire and external shield, the shield side is exposed to the external noises. Therefore, it results in not only to be easily effected by the noises, but the signal wire also being invaded by the negative effects.

 

In addition, we are using a high pure copper wire PC Triple-C onto the secondary coil winding and together with a large EI core, we brought into effect an outstanding frequency characteristic and phase characteristic at a wide band.
