Unpacking the Pioneer SX-828: Power and Performance
At the heart of the pioneer sx828 lies a formidable power amplifier section, delivering 54 watts per channel into 8 ohms in stereo mode. While this figure might seem modest by today’s standards, in the context of 1970s audio engineering, it was more than sufficient to drive most speakers of the time with authority. The receiver boasts a wide frequency response, stretching from a deep 5Hz up to 80kHz, ensuring that the full spectrum of audible frequencies is reproduced with clarity. A low total harmonic distortion of just 0.5% further contributes to the clean and accurate sound signature of the pioneer sx828. The damping factor of 40 indicates good control over speaker cones, resulting in tight and well-defined bass, a characteristic often praised in reviews of this model.
Superior Tuner Capabilities: FM and AM Reception
One of the standout features of the pioneer sx828 is its exceptional FM tuner section. Equipped with a linear scale tuning dial and dual tuning meters, it offers precise and user-friendly station selection. The advanced solid-state circuitry within ensures remarkable FM selectivity and sensitivity. This means the receiver is adept at pulling in weaker FM signals while rejecting interference from adjacent stations, a crucial aspect for listeners in areas with crowded FM bands. While AM is also supported, the FM capabilities are where the pioneer sx828 truly shines, providing a gateway to high-quality over-the-air broadcasts.
Versatility and Connectivity: Bridging Vintage and Modern Audio
Despite its vintage roots, the pioneer sx828 offers a surprising degree of versatility to accommodate various audio sources and setups. It features two tape monitor circuits, facilitating tape-to-tape duplication, a common practice in its era. Furthermore, it provides inputs for two turntables, catering to vinyl enthusiasts, and even includes microphone inputs for basic recording or PA applications. The receiver allows for connecting up to three sets of speakers and two sets of headphones, providing ample options for audio output. Input sensitivity specifications highlight its compatibility with various cartridges (MC and MM) and line-level sources, making it a flexible hub for a vintage or even a hybrid audio system.
Design and Build Quality: A Testament to Pioneer Craftsmanship
The pioneer sx828 is not only about sonic performance; it’s also a visually appealing and robustly built piece of equipment. Its dimensions of 485 x 150 x 375mm and a weight of nearly 15kg speak to its substantial construction. The use of high-quality semiconductors, including FETs, ICs, transistors, and diodes, reflects the component quality of the time. User reviews often praise the overall build quality and handsome aesthetics of the pioneer sx828, emphasizing its solid feel and enduring design.
