PREDA is a solid state preamplifier with analog IN/OUT employing state-of-the-art transformer-type volume control system. The transformer uses super-reliable lead relays with 54-step, permitting precise setting with perfect Infrared remote control. Unlike conventional resister-type attenuator, the transformer system has no loss of signals, as heat, enabling precision volume control settings. Aurorasound’s newly developed discrete amp-module, having achieved ultra wideband and low distortion, balances input signal sources and adopt any type of output power amplifiers with excellent signal control.
PREDA is developed with a completely new concept by adopting independent block for power supply, amplifiers, input and output modules for each L/R channels. A heavy duty solid aluminum chassis, extruded knobs, anti-vibration foot insulators are employed to achieve the highest-level musical performance, operation and aesthetics. It is an ideal preamplifier as the center core of your audio system.
Apr.2014, Gain select switch is added on the bottom of chassis. This function is more minus 16 step down foe mid-night listening.
