The PH1 caters for MM, low output MC and high output MC cartridges. Never connect MM and MC cartridges at the same time as there will be a possibility with the high amplification factor that some noise could occur at the output stage. The selector control on the front panel of the PH1 has only two options(MM or MC) even though it accepts high output MC. The circuitry has been designed so that it will automatically sense which type of moving coil cartridge is being used and settings will adjust accordingly provided the correct selection is made from the toggle switch on the rear panel. The power supply of the PH1 is provided by 10 NCR18650 batteries charged via a 24V power adaptor. The PH1 must be fully charged prior to use, a simple process with all necessary information clearly displayed. In full use conditions, the batteries can be charged up to 10,000 times with each full charge lasting for up to 8 hours. Yves-Bernard André has designed a specific moving coil transformer for use in the PH1. Because of its design, the YBA transformer is uniquely suited to meet the different characteristics of moving coil cartridges. It allows for the finest details of a reading to be highlighted at a very high level. YBA MC TRANSFORMER TECHNICAL CHARACTERISTICS Cartridge impedance 3Ω to 100Ω Output impedance 47kΩ Bandwidth 10 HZ to150 KHZ Gain 26 dB Shielding full mu-metal Double 46cm x 36cm x 26cm – 7kg
