Connectivity Without Compromise
Quad is proud to introduce Vena, a new user-friendly amplifier designed to be the perfect match to an amazingly wide variety of digital and analogue sources.
Vena has captured the essence of advanced Quad engineering in a world of modern technology. Whilst retaining the original design philosophy, users now have access to digital inputs including Bluetooth playback, in a compact amplifier without compromise on sound.
Both Quad loudspeakers and electronics are known for their transparency, accuracy and natural reproduction of your music - Quad Vena is no different. Our engineers have paid special attention to our high resolution DAC and even for Bluetooth or USB playback you can expect ‘the closest approach to the original sound’ – our key to precision hi-fi manufacturing.
Quad Vena Aesthetics
Vena encapsulates advanced engineering and sound quality inside a neat package that is bound to find favour with today’s space conscious listeners. In typical quad style, the simple fascia is dominated by a large volume control with an array of push buttons providing input selection.
The Quad Vena is available in a variety of finishes to complement your Quad loudspeakers and living space. A choice of high-gloss piano-style finishes in white or black, figured sapele mahogany wood or an ultra-clean gun-metal grey finish are available.
Connect Effortlessly To Vena
Two analogue inputs are mirrored with a variety of digital options from Optical and Coaxial to USB plus the unusual inclusion of direct linking to iPhone, iPad and iPod digital outputs using the standard A type USB connector. Vena’s high resolution DAC is enabled for any sampling frequency up to 192kHz/24-bit.
In addition any Bluetooth® equipped source can link to Vena wirelessly with optimum sound quality ensured by the innovative aptX codec.
Vena’s loudspeaker output (45W per channel into 8 ohms) is matched by a front panel headphone socket. Digital Optical and Coax outputs in addition to an analogue Preamp out make Vena a truly versatile control unit. Remote control of volume and input selection is available from the included handset.
In one neat package QUAD Vena provides the necessary amplification to realise the highest quality of both digital and analogue music sources through any partnering loudspeakers or headphones. And, of course, you can expect the legendary QUAD sound performance through the precision engineering that has been the hallmark of QUAD since 1936.
