    Default Aurorasound PREDA Line level control amplifier

    Pure Sound is pleased to announce the UK arrival of the Japanese made Aurorasound PREDA line level Control Amplifier.



    PREDA is a solid state preamplifier with analogue IN / OUT and employs a state-of-the-art autoformer type volume control system. The transformer taps are switched using super-reliable reed relays from UK manufacturer Pickering Interfaces and incorporates 54-steps allowing precise setting with perfect Infrared remote control. Unlike the conventional resistive attenuator, this transformer system loses no part of the signal as heat and enables more accurate control of the listening level. PREDA also includes Aurorasound’s newly developed discrete amp-modules which feature exceptional bandwidth and ultra low distortion. It can balance input signal sources and drive any type of power amplifier with excellent signal control. PREDA was developed adopting a completely new modular concept and deploys independent blocks comprising power supply, input and output stages for each L/R channel. A heavy duty solid aluminum chassis, extruded knobs and anti-vibration isolating feet are employed to achieve the highest levels of musical performance, operation and aesthetics.


    Features

    6 Inputs. 2 x Balanced via XLR, 4 single ended via RCA sockets

    2 Outputs. 1 x Balanced via XLR, 1 single ended via RCA sockets

    All RCA sockets are Rhodium plated.

    Maximum 10 dB Gain

    54 step transformer attenuation switched via UK made Pickering Interfaces reed relays.

    Input selection, volume level, balance & phase reversal all accessible via IR remote control.

    Newly developed wideband (12MHz) gain modules for input/output buffering.

    Fully independent L/R architecture for true dual mono operation.

    Substantial aluminium casework & isolation feet.



    UK RRP £7999.95

    Very nice, Guy. I like

    If it sounds as good as their phonostage, it'll be something special indeed!

    Thanks Marco. It is a very nice sounding linestage & does share some characteristics with the Vida.

    Both should be in use at the upcoming Cranage Hall show in June.
