Quick review 2.0 multimedia system Microlab Solo 9C


    Family Acoustic Microlab Solo from the company recently replenished model Solo 9C, which at the time of publication of this material have already been the most price-lists profile of online sellers.

    Within this rapid test we will try, first, to evaluate its design and sound, and secondly, to compare it with other popular system of this series, Solo 7C New, who has recently visited our editorial.

    So, Microlab Solo 9C is based on a 3-way circuit with two rear bass reflex and two identical 6.5-inch full-range speaker for the formation of MF and LF channels. However, further differences begin that only intensified with the deepening of the details.

    For example, Solo 9C flaunts a 1.5-inch tweeter (vs. 1-inch), large displacement (mainly due to greater heights) and, consequently, a larger total output power: 140 W RMS against the model 110 Solo 7C New.

    It is clear that even this is enough to expect from today considered acoustics sound very different, and there is also a significant difference between the amplifier circuitry of these two systems. In addition, the system has a Solo 9C and another ace in the hole – an extra set of modern digital inputs, including HDMI, Toslink optical and coaxial, and output HDMI.

    As a consequence, the price at Solo 9C higher than Solo 7C New, which is also quite logical. For some, the presence of digital inputs and outputs can be a decisive factor in the final selection, but in today’s article we will try to still primarily focused on the sound quality, which, even if judged by only one first look at the characteristics that simply must be different.

    In the retail system Microlab Solo 9C comes in a single package of the usual cardboard with a simple but clear enough clearance.

    Supply system includes two speakers – active and passive, set mezhkolonochnyh cables with RCA-type “banana”, cables for digital interfaces (full-size HDMI, optical, coaxial), as well as remote control, user manual and warranty.

    Columns made of MDF board with the traditional black “embossed” coated front panel and laminate “wood” on the sides with rounded corners.

    Removable false panel, covered black decorative fabric, fixed column using conventional axial slots at six corresponding holes.

    At the bottom of the active speaker, at the level of the logo is a double 7-segment display on the red LEDs that can be used to visually monitor the input selection and volume and timbre. On the passive column for symmetry in this place is a decorative label.

    External tembroblok located traditionally in the oval hole on the side surface of the active speaker, could be called typical, with its three regulators, if not for one thing: other than adjust the volume and timbre, here you can switch the input signal sources. Very convenient.

    The supplied infrared remote control is comfortable enough, you can control all functions of the system and in addition supports the inclusion function Stand by.

    High 1.5-inch speaker has a domed emitter impregnated silk and magnetically shielded, 4 ohm.

    This three-band system design also includes two midrange 6.5-inch magnetically shielded speaker, 8 ohms. This is the time to mention that these speakers are similar to that used in the system design Solo 7C New only fundamental characteristics diameter and winding resistance.

    Speakers Solo 9C do not have decorative “aerodynamic” cones in the middle, instead of glossy coating present shallow corrugation, though still talking about plastic diffusers on the rubber suspension.

    One of the 6.5-inch speakers located below the tweeter – in a single acoustic space with him – and is set to play a wide LF RF spectrum.

    The second 6.5-inch speaker located at the bottom, isolated from the two upper horizontal partition – he is responsible for the reproduction of low-frequency component predominantly spectrum.

    On the back side you can see the phase inverter columns, one for each isolated volume – HF MF and LF. Several enlarged relative to the internal volume of Solo 7C speakers gives hope for a better return of Solo 9C in the lower frequencies.

    Switch and the power cable, terminals for connecting mezhkolonochnogo cable system with two analog inputs, digital inputs and outputs interfaces – these are located on the back of the active speaker.

    Almost all the electronics system is located in the active column in a single chassis in the form of a metal plate is removed after unscrewing the screws. Step-down transformer on the classic w-shaped plates attached directly to the bottom of the column (see photo above), has three secondary windings of these two 21-volt power supply is used for the formation of a midpoint.

    Nodes rectifying and stabilizing voltage, the switching of input channels and three amplifiers wired circuit boards fixed in turn, together with the radiator output stages on the chassis, charge separation filters installed on the sidewall adjacent the bottom phase inverter. Soldering, mounting and assembly quality components at a height.

    For those who choose between Solo 7C and Solo 9C, give another big difference between them: in the first case we are talking about the final amplifier analog discrete components, the system Solo 9C output stage amplifier operating in class D, performed on the integrated circuit (just for her design provides heat sink made of aluminum profile).

    Test results. Conclusions

    Thanks to eye-catching design with the original ratio of height and width, as well as a successful combination of decorative finishes, novelty appearance looks very presentable and noble. Model Solo 9C in some interior could easily be mistaken for a class speaker Hi-End, if not antique “red-eyed” 7-segment LED antediluvian era heyday group Kraftwerk.

    The sound system Microlab Solo 9C expected clean, without audible distortion and substantial background noise even at maximum volume settings and timbres. More information about the tone adjustment would like to say the following: treble performed Solo 9C model has a very wide range of course, but little sense to remove it from “neutral” not because of the high character of the sound spectrum of this system is already quite clean and smooth. Remove to “clatter” and “hiss”, of course, still does not work, but it’s not the same: high-frequency spectrum in most involved when listening system without adjusting the compositions and is very close to what we can expect from this class of multimedia systems therefore it is sufficient to leave the treble knob in the middle position and more to him not to return.

    The sound system Microlab Solo 9C in the mid and low frequencies is less clear. After a series of experiments with listening the most dynamic musical compositions control the bass was left in a position slightly above neutral – and with the installation of the sound system seemed to be the most satisfactory even in jumpstarting genres listened music recordings.

    As in the case of the previously studied system Solo 7C New, Solo 9C model sound when listening to the majority of jazz and rock compositions can be described as very good, much better than average sound home entertainment acoustics. However, it should be noted that some specific powerful vocals, as well as a number of musical instruments with a pronounced low-frequency component (double bass, saxophones, bass guitar), in the case of Solo 9C sound much more colorful and more natural than in the case of Solo 7C New, and in general, the entire range of low and medium frequencies in the system under consideration today was more expressive and more “dense” filled.

Nevertheless, should not deceive ourselves and expect from this system more than foreseen its price. For example, a number of complex terms in the spectral compositions, especially classical and church, with a strong component of choral singing on such systems still will not sound.

    Now the price for system Microlab Solo 9C in online retail ranges from $ 280 – $ 340. For multimedia 3-way active bookshelf stereo sound with this level, and in addition to the full range of digital interfaces price is justified and adequate.
