At the end of last year, the company Edifier announced the completion of its flagship line of multimedia speakers Edifier Studio several interesting innovations, among them – the hero of today’s review, active system Edifier R1280T. Common to the entire family Studio is still a wonderful classic design with wooden decoration and a fully digital path. Innovation can be called extremely modest size 2-way system Edifier R1280T: still such small models in the top series not Studio produced.

Although compact, the model Edifier R1280T develop a pretty decent power — in the amount up to 42 watts RMS, which is quite impressive value for the table design. Novelty is equipped with two analog inputs with RCA connectors and comes with a wireless remote control. To this we must add enough affordable retail price of less than 3 000 at the time of publication of this material. So in our current testing can only find out how good the appearance corresponds to the quality of workmanship and, most importantly, the sound quality of this system.

Design and execution

The system comes in a compact (as possible) package and the package actually includes two columns — active and passive, micronuclei signal cable, remote control, manual and warranty card.


Book traditional textbooks format – that is, perhaps, more suited for comparison with the dimensions of each speaker system Edifier R1280T. They are really extremely compact, while at the same time, there is all attributes of “adult” columns — decorative grille, two speakers, bass reflex, noble rendition of “under the tree”. Such acoustics, no doubt, will decorate any interior, including the rigorous environment of a solid Cabinet.


The body column is a classic parallelepipeds, the width slightly less than the depth. Case material – the traditional flagship system Edifier MDF (MDF — Medium Density Fiberboard, “wood-fiber plate medium density”) top class E0, which means high quality, stable parameters, resistance to moisture and complete absence in the composition of formaldehyde and other toxic substances.

We turn now to the study of the components of the system — and start with the tweeters. In this case, the playback high frequency range assigned to 1/2-inch (13 mm) tweeter dome design with silk diffuser and magnetic shielding. The resistance of the tweeter is 4 Ohms.



Diffuser sredneaziatskogo dynamics with a diameter of 4 inches (116 mm) made of pressed paper interspersed with wool. This combination of materials we have seen in the design of sredneshirotnykh previously tested and the much appreciated 2-way system Edifier R1900TII. Mid-bass woofer features a magnetic shielding, the resistance is 6 Ohms. Phase inverter with a front-located calibrated at 75 Hz.


We turn now to the study of “content” active speaker.


The power supply system placed at the bottom of the active speaker, supports any voltage in the range of 110-240 V. the scheme of the pulsed conversion it is characterized by compact sizes, high efficiency and low loss on heating. The PSU is equipped with its own screen of blackened foil.


Traditionally, family Studio main electronics system Edifier R1280T is on the Board combined with the rear communication panel, which, in turn, derived both input and output on the second column.

System Edifier R1280T made on the basis of a fully digital tract using amplifiers class D. as terminal amplifiers used chips from Texas Instruments TAS5713 with built-in equalizer and digital signal correction (DRC, Digital Room Correction), and the controller STM8S103 and the reference crystal oscillator on the chip NJU6368. Chips TAS5713 is a powerful class-D amplifiers, providing the output power to 25 watts at a voltage of 20 V and load of about 8 Ohms, with independent channels of 24-dB with adjustable volume control and supports digital input semplirovannyh 8-48 kHz. Amplifiers made in a compact 48-pin HTQFP case dimensions 7×7 mm, equipped with a heat sink (in our case it is the plate carrying bracket rear communication Board). Moreover, as the ADC used chips from Texas Instruments PCM1808 (dynamic range 93 dB, 24-bit Delta-Sigma analog-to-digital conversion with 64 times oversampling and the frequency of the sampling rate 8-96 kHz).

The volume and tone on a separate Board, mounted on the side of the active speaker. Volume control is an encoder with a characteristic “steps” when changing volume from minimum to maximum, tone controls bass and treble uses a conventional rotary knob with lock the “zero point”.

The supplied delivery system R1280T infrared remote control allows you to vary the volume or mute the sound and change the level from low to high frequencies, that is completely duplicate functions built into the active speaker of the tonestack. The power panel is supplied from two batteries form factor AAA. Wired remote control system is not included.


Practical tests

Speaker system Edifier R1280T refers to the models table, or as them still name, shelf type — it is designed primarily for music playback. So if you looking for acoustics to reproduce the clank and rumble of the battle scenes in games or movies, it is better to look towards something else with the subwoofer.


The system specifications provided the lower limit frequency of 75 Hz, and it is very good that the manufacturer did not go to the embellishment of this option, as some do, by manipulating the characteristics of the frequency response. But the 75 Hz the system works with full dedication and dynamics. In particular, the wonderful sound of jazz with the classic brass and shipovymi tools, such as Vaya Con Dios and most of the works of Louis Armstrong. By the way, in both cases looks very expressive vocals, and in General any song with a distinct male or female vocals, this system plays very well and reliably — thanks to the almost linear section of the frequency response up to 1.5 kHz.

The same can be said for songs of all genres with a predominance of acoustic instruments, and even symphonic compositions while playing several classical works. Except that with the chorales is not so good, lacks a bit of dynamics, but is clearly affected by the small size of speakers.

Quite accurately reproduced most rock-n-roll, rock and pop songs, however, in some cases — especially with a vibrant rhythm and rich digital effects in the film — the sound takes on a somewhat unusual color, which, however, can be assessed only in a positive manner and which after some time gets used as a certain pleasant features of the sound of this system. Listen to dynamic recording of Aerosmith, KISS, AC-DC and you’ll understand what it’s about.

With metal is not all that bright speakers still sometimes not enough, especially if we are talking about brutal trash – and death metal. But since when connoisseurs “metal” listen through desktop speakers?

I would like to stress again that all these subjective assessment of sound produced relative to similar systems of the same bench shelf class, and among them, to give it its due, the system Edifier R1280T is probably one of the best choices. When compared with full-length high-quality multimedia acoustics victory definitely get, for example, the same Edifier R1900TII, however, the dimensions, and the price in this case will be completely different.

Finally we offer to your attention the amplitude-frequency characteristics taken by the manufacturer under real conditions, in the workplace apart and connected speakers.

Total

At the time of writing, Edifier R1280T was offered in Moscow online retail in the price range of 2 600 to 3 400 rubles. Less than a hundred dollars per set of multimedia active 2-channel system, expertly made in the classic case “under the tree”, with a thoughtful blend of features, impressive output with a total capacity of 42 watts RMS and is excellent for such a compact device the sound. Requested for the price is adequate to its possibilities – of course, with the condition that you are looking for is a desktop system and do not intend to replace it with something bigger.
