Quad Artera Stereo
Quad Artera stereo power amplifier, 140 Watts RMS per channel, designed to drive demanding speakers with stability.
Description
The Artera Stereo is a stereo power amplifier from Quad, designed to amplify the signal from a preamplifier and power a pair of speakers. Every stage, from the transformer to the input terminals, has been developed to deliver power, musicality and stable operation.
The unit delivers 140 Watts RMS per channel, sufficient power to drive high-end speakers. It incorporates the patented Current Dumping technology, which maintains amplification stability even under demanding dynamic and transient conditions, that is, during musical passages requiring rapid and substantial power variations. The balanced XLR inputs, specially developed for this unit, offer robust connections combined with a high signal-to-noise ratio, limiting interference on the audio signal.
This amplifier is aimed at users with a hi-fi system featuring a separate preamplifier and demanding speakers, seeking stable amplification capable of reproducing dynamic passages without faltering.
What to check before buying used
On a power amplifier of this generation, the power supply capacitors and protection relays deserve particular attention, as they are used continuously and can degrade over time. A check of the balanced XLR inputs and speaker output connectors is worthwhile to confirm there are no loose contacts. It is also useful to run the unit for a while to ensure there is no background noise, hum or unexpected cut-outs.
