Aurorasound PREDA III Pre Amplifier

£10,995.95

Pre-amplifiers’ fundamental function/responsibility in audio systems are to accept various audio signals, select one, adjust volume level, then feed to power amplifier with good signal conditioning. PREDA-III executes these tasks faithfully by employing true balanced signal path, coupled with complete L/R independent monaural structure. PREDA-III accommodates both XLR balanced and RCA un-balanced inputs, for CD player, DAC, phono stage, tape deck, etc. In addition, the output of both XLR balanced and RCA un-balanced perfectly matches to any kind of power amplifiers.

The components such as Input/output connectors, selectors, amplifier modules, volume controller, power regulator function, ridged/robust body structure are the key factors to achieve super performance of amplifiers. PREDA-III is precision designed with absolutely no compromises in all those factors. Noiseless sector switching, noiseless power on/off, controllers knob operation touch and feel can offer satisfaction in your music listening experiences. PREDA-III pre-amplifier not only makes the best match with PADA-300B tube power amplifier, but also, it makes a good partner with any tube and solid-state power amplifiers in the market.

FEATURES:

L/R complete monaural structure in one chassis

The left and right channels are completely independent in terms of input/output signal paths, amplifications, power regulators, and power transformers. Ideal layout with the shortest signal path, optimized placement for channel isolation, and temperature stability and vibration-absorbing make PREDA-III the perfect pre-amplifier.

True balanced signal path and amplification

All XLR balanced input signal flows through the XLR balanced and RCA un-balanced signal outputs. RCA un-balanced signal input also transforms to XLR balanced and RCA un-balanced signal outputs. PREDA-III supports any input/output combinations, such as XLR in XLR out, XLR in RCA out, RCA in XLR out, RCA in RCA out.

Aurora AMP-2 Rev.4, new developed amplifier module

New development amplifier module, “Aurora AMP-2 Rev.4”, this is x1.5 higher speed improvement and lower noise performance in comparison with the original PREDA module. Employs NEC and Toshiba-made discrete transistors/FETs, WIMA film capacitors, and TAKMAN metal foil resistors, which is Bi-Cr-Al materials with brass cap and oxygen free copper lead wire crafted by precision laser trimming. This amplifier module has blue color aluminum top cover to keep operational temperature stability and noise shielding.

ALPS made large sized precision volume control

Machined brass 50mm diameter body, very low distortion and hi-fidelity resistor material, gold plated multi wire slider brush on mirror surface resistor. True high-end volume controller with excellent touch and feel deliver smooth and comfortable man/machine interface. This volume is sandwiched between input buffer amp (Aurora Amp module-2 Rev.1) and output buffer amp, in order to make good signal conditioning. No high frequency degradation, neither sound loss in any position of volume setting occur. NO REMOTE!

Neutrik made XLR connectors / Rhodium plated RCA connectors

Professional grade connectors for excellent reliable signal interface with life-long durability.

Optical encoder with machined aluminum knob for input selector

For input selector function, Burns-made optical encoder and OMRON-made high-reliable relay are controlled by micro controller, in order to make the shortest signal path and noiseless operation. Resume memory is equipped at power on/off sequence.

Global phase selector

This function allows changing phase status, either normal or inverse. You can select optimum position to meet recorded medial conditions. Also, works for XLR output hot/cold change to meet your power amplifier.

Solid aluminum casing

Front panel is of 10mm, side 8mm, top and bottom 5mm thick solid aluminum by precision machining. Very rigid and robust body design supports amplifier circuit boards and power transformers. Cast iron foot insulators absorb unnecessary vibration.

Throw back Thursday (is that still a thing?) to the @greenwich.peninsula 'Rhythm & Taste' event we provided the audio systems for. Feedback for the day's jazz soundtrack played on @soulnote3 electronics, @horaaudio COCO loudspeakers @transrotor_o
One of the most impressive and beautifully designed modern integrated amps - the SU-R1000 is pure Technics wizardry. 150W of clean, fast power. The build in, DSP-powered MM/MC phonostage measures your cartridge, applies custom EQ curves, and corrects
