The Alchemy PPA-2 is a full-featured phono preamp that uses all analog, discrete FET gain and EQ stages to transform microscopic grooves in vinyl into stunningly lifelike music. The PPA-2 can be tailored to specific cartridge requirements, with switchable gain for each channel, MC cartridge loading, and stereo or mono operation. A selection of RCA or XLR inputs and outputs adds even more flexibility to the most versatile phono preamp in its class.
Features:-
• Fully discrete, balanced FET topology from input to output
• DC servo-controlled output stage
• Switchable MM or MC gain for each channel
• MC loading continuously adjustable from 5 Ω to 999 Ω
• Precise MC cartridge loading settings for each input can be displayed on the LCD information screen
• Selectable Stereo or Mono operation
• Highly precise RIAA equalization using 0.1% metal film resistors and selected metalized polypropylene capacitors
• Selectable rumble filter
• All signal routing through hermetically sealed gold-on-gold relays
• Ultra-low-noise DC voltage regulators
• Microcontroller completely shuts down during normal operation to eliminate any clocking noises
• Internally shielded toroidal transformer and linear power supply for very low radiated hum field
• Provides an improved power source for the Miracord 70 and 90 turntable motor
• 12 V trigger input
• Liquid Crystal Display for clear user information
