Những điểm nổi bật của sản phẩm âm thanh hi-fi Pioneer SC - LX 90

Over the last few years Pioneer has offered some quite high-end home theatre receivers, but the Pioneer Susano SC-LX90 is in a class well beyond that. It is also different in not being a receiver, but an amplifier — that is, it does not have a radio tuner built in. Aside from that, and one other item, this is about as fully functioning and capable a home theatre powerhouse as you’re ever likely to come across.

AV Receivers Hi-fi Pioneer SC-LX90 is Pioneer’s statement of intent at the upper echelons of the AV amplifier market, sharing the same piano-black fascia and cosmetic cues as the company’s top-end plasma screens. And there’s no denying it’s a bit of a looker. The fit and finish is exemplary, the styling subtly sophisticated for such a massive beast and the cabinet surpasses even Denon’s battleship AVC-A1HD for sheer build quality.

Internally the design runs to the usual extremes of Japanese hi-fidelity fastidiousness and sumptuous component choice. The result is nearly 36kg of AV processor/preamp and ten channels of power claiming 140W into 8ohm. Unlike the direct competition, the Denon and Yamaha’s DSP-Z11, the SC-LX70 uses Class D ICEpower modules rather than traditional Class A/B analogue power stages.

This ought to reduce weight, size and power consumption – a theory somewhat denied by its sheer mass and the sizeable cooling fans. The reason is explained by the Susano’s sonic prowess, says Pioneer (albeit in a 10-page PDF document rather than in those few words). Not only is this a THX Ultra2 Plus approved amp, it carries the AIR Studios ‘Monitor reference’ seal of sonic approval – its highest recognition.

In the middle of this frontage is a display, but not the usual LED one. Instead, it is a colour LCD screen measuring 110mm wide and 63mm tall, basically in widescreen format. This shows full menus, including the set-up one. By default this shows signal information, identifying which channels are being delivered by the source, and such things as the bit-rate for Dolby Digital, the sampling frequency of the digital sound, the dialogue normalisation setting and so on. But by using a button on the front panel, you can switch this to show the video source (so you can watch your DVDs on the screen), or the source overlaid by the signal information. This really lovely little feature is diminished significantly by the fact that it only works for analogue video inputs, not HDMI ones.

The receiver is huge, heavy, and fully loaded with amplifiers. Ten of them in fact. You get five configuration options for the speakers. ‘Normal’ provides for 7.1 channels, except that the two regular surround channels receive an ‘array’ treatment, in which each gets two speakers (that means nine of the amps are used). ‘All Ch Bi-Amp’ delivers 5.1 channels, with two amps for each channel. There is no active crossover, though, so all frequencies are delivered to each driver, leaving the loudspeakers’ passive crossovers do their usual jobs. ‘Front Bi-Amp’ gives you six amplifiers for the front three channels and a single amp for each of the surround and surround back channels. Then there are two ‘7.2’ channel settings, one of which releases two of the amps for a second zone, while the other allows for a ‘B’ set of stereo speakers.

Each of the amplifiers offers 140W, and Pioneer says that the receiver can deliver maximum power from all of the channels at the same time. The amplifiers use Bang&Olufsen’s IcePower technology, which is a particular type of digital amplifier. That allows a lot of power to be generated with high efficiency, reducing wasted heat.
