ELEX MK4 

The Elex MK4 is a high performance stereo integrated amplifier designed to deliver the purest musical performance. Housed in a brand new case to match the rest of the Rega range, the MK4 builds on previous Rega designs using our multi-award winning class A/B power amplifier circuit which delivers an impressive 72W per channel into 8Ω loads (90W into 6Ω). New rear connectivity options are available with the Elex MK4 now including a Rega DAC circuit with two digital inputs and a high quality headphone output conveniently located on the front panel.

Bringing your music to life

The Elex MK4 is capable of driving difficult loudspeakers with ease and will integrate perfectly into any audio system by offering a wider range of connectivity options. In addition to the line level, digital inputs and a high quality moving magnet phono stage,  you will also find Pre-out and Record Out functionality alongside a headphone output. Special attention has been paid to the selection of key audio components. Discrete circuitry, high quality relays, polypropylene capacitors and Sanken output transistors are used throughout the design.

PRODUCT DETAILS

AMPLIFICATION CIRCUIT

Our engineers have re-engineered the entire ELEX circuit board to optimise performance. MK4 builds on previous Rega designs by using our multi-award-winning Class A/B power amplifier circuit to deliver a powerful 72W per channel into 8Ω loads. This power is provided by a quiet multi-stage linear supply whilst supply rails for digital and analogue sections are galvanically isolated.

DIGITAL CIRCUIT / DAC

The DAC is based closely on the hugely successful Rega DAC-R circuit. The galvanically/optically isolated digital inputs utilise a Wolfson S/PDIF receiver IC to provide exceptional detail and clarity from any connected source. Output is provided by a Wolfson DAC and Rega designed discrete line-driver circuit. Our engineers have worked exceptionally hard to ensure that the analogue side of the circuit is not affected in any way by the introduction of digital inputs.

MM PHONO STAGE

A high performance Rega designed integrated moving magnet (MM) phono stage is carefully built into the circuit. The RIAA equalization has been split into two stages to minimise interaction. Polyester capacitors have been used in the signal path and polypropylene capacitors are used in the RIAA equalization circuits.

HEADPHONE OUTPUT

We have taken great care to incorporate the headphone socket on the Elex MK4. This has been configured such that the speaker switching is performed by the output mute relay to avoid obstructing the signal path ensuring no loss of performance when it is not in use.

CUSTOM CASE

The new custom case design and construction brings the Elex MK4 inline with the rest of the Rega range and provides improved heat dissipation by using the entire case as an ultra efficient heat sink.

PROTECTION

The Elex MK4 includes Thermal Cut-Out, short circuit protection and DC protection to prevent the risk of damage from excess heat, excessive currents or short circuits.

Focal Chora 816

IDEAL FOR HOME CINEMA

Key points

• Suitable for both hi-fi and Home Cinema configurations
• New speaker drivers with Slatefiber cone developed and manufactured in France by Focal
• Time Alignment thanks to the tilted stand: better soundstage

2.5-WAY FLOORSTANDING LOUDSPEAKER​

The Chora 816 model is a 2.5-way bass-reflex floorstanding loudspeaker. Its woofer and midrange/bass speaker driver, both equipped with the Slatefiber cone, work in perfect harmony for a voluptuous sound reproduction and a perfect bass impact. The sound finds its full dimension in your listening room, with a dynamic midrange and remarkable power handling. A front port is placed below the loudspeaker to reduce distortion and, thanks to the tilt of the loudspeaker stand, Time Alignment provides a soundstage focused on the listener.​

Chora 816 is particularly well suited for Home Cinema listening and blends seamlessly into rooms of up to 323ft² (30m²).

家庭影院的理想之选

2.5路落地式扬声器

Chora 816是一款2.5路低音反射落地式扬声器。它的低音喇叭和中音/低音音响驱动均配有石板纤维音盆，两者完美协作，以更加饱满的方式再现原声，同时让您感受完美的低音效果。声音在房间中获得充分的表现空间，您可以感受到动力十足的中音以及强有力的处理。正面接口位于扬声器下方以减少失真。得益于倾斜的扬声器支架，“时间一致性”则带来了专注于聆听者的声场效果。
Chora 816尤其适合用于家庭影院，能够与最大323平方英尺（30平米）的房间完美融合。

SOFT AND PRECISE TREBLE​

The surround linking the dome to its stand uses a memory foam material called Poron. This surround is directly derived from the Utopia’s famous Beryllium tweeter and reduces distortion by a third between 2,000Hz and 3,000Hz, the ear’s high-sensitivity range. The spatialisation and very low directionality of the inverted dome allow silky trebles to be heard from any point in your listening room.

TNF铝/镁高音喇叭

柔和和精准的高音

环绕音箱用名为Poron的记忆海绵材料将圆顶连接到支架上。该环绕音箱直接源自Utopia知名的铍高音喇叭，能够在2000Hz 和3000Hz之间减少 30%的失真，这是耳朵最高敏感度的范围。倒圆顶的空间化和极低的方向性能够然供您在房间内的任何一点都能听到丝滑的高音效果。

PERFECTLY BALANCED SOUND​

Slatefiber technology, exclusive to Focal, involves the use of recycled, non-woven carbon fibres applied as a sandwich between two layers of thermoplastic polymer. In their quest for perfection, Focal engineers have opted to use non-woven carbon fibres, all pointing in the same direction to achieve even greater rigidity and better damping.
Manufactured in the Focal workshops using an ultra-modern industrial tool, the “slate” effect of the cone provides better damping and rigidity, but also lightness – the three “essentials” of a good speaker driver. 

石板纤维音盆

完美均衡的声音

Focal专属的石板纤维技术涉及对再回收、无纺布碳纤维的运用，将其夹在两层热塑聚合物之间。为追求完美，Focal工程师们选择使用无纺布碳纤维，这些都是为了实现更大的刚性和更好的阻尼效果。 
音盆是在Focal工厂中借助极为现代的工业工具打造而成，其“石板”效果具有更好的阻尼和刚性，同时也更轻便——这是优质音响驱动的三大“必备品质”。. 

A SLEEK, MODERN DESIGN

​The Chora range boasts a modern design, all lifted onto a tilted stand for Time Alignment, which provides an optimal soundstage, more focused on the listener. The slate colour of the Slatefiber cone adds a final refined, authentic touch. 

顺滑而现代的设计

Chora系列以其富有现代感的设计为主要特色，将一切都置于倾斜的支架上，以达到”时间一致性”的效果。这提供了一种优化的声场，更加专注于聆听者。石板纤维音盆的“石板”颜色也让产品更显精致和逼真的感觉。

ON-TREND FINISHES​

Chora is available in three finishes: Black, Light Wood and Dark Wood. On-trend colours that blend into different interiors and lend them a unique aesthetic signature.

时尚的饰面效果

Chora推出了3种饰面效果：黑色、浅木色和深木色。时尚的色彩与不同的室内装饰融为一体，让它们呈现出独特美感。
