FAQ（Frequently Asked Questions）

• About using the monaural cartridge

  Noise comes out when using a monaural cartridge of other manufactures

  When playing a monaural record on a stereo system, pay attention to the cartridge used.

  Single-coil type monaural cartridge causes a ground loop and it becomes the origin of hum noise.

  PP-Mono adopts a dual coil design, and you can enjoy playing monaural records even in a stereo system.

  

  When using a single-coil monaural cartridge, you can avoid the ground loop by connecting only one channel and bifurcating the output side of the phono amplifier.

• About the balanced connection of the MC step-up transformer

  What is a balanced connection between a cartridge and a transformer?

  A The power generation of the cartridge is a balanced (push-pull) operation in which signals of opposite phase flow through both ends of the coil. To transmit this with an unbalanced connection will not only loose the merit of the balanced connection, but will also cause external noises to effect the sound quality. The MC step-up transformer T-500/550/1000/2000 having a balanced input and the EA350/500/550/1000/2000 which have an internal MC step-up transformer can bring superb sound quality even if unbalanced type phono cables are used, however by using a balanced type phono cable, transmission loss can be minimized and even higher sound quality can be achieved. This effect is enormous, even the phono amplifier built into the preamplifier, a large sound quality improvement can be expected by using the T-500/550/1000/2000 and a balanced phono cable with receiving the signal at the MM position.
