remember that this figure is measured and guaranteed over the entire spectrum from 20 to 20,000Hz.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The SX-838 is distinguished from all other receivers in its price range by offering switched-turnover flexibility in its tone control operation, permitting the creation of a variety of tonal characteristics to match your room&#8217;s acoustics or your mood.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And when it comes to versatility, it reproduces no less than six program sources (AM, FM, Phono 1, Phono 2, Mic and Aux).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It also has two stereo sets of tape deck connections with monitor switching (and deck-to-deck duplication).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you wish, use the noise-reduction adaptor terminals to connect a third tape deck.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This unit is provided with a special Recording Selector, enabling you to record FM broadcasts while listening to the disc reproduction and vice versa &#8211; a unique time-saving device for your listening pleasure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A total of three pairs of stereo speaker systems can be connected to the SX-838 (with a front-panel switch to use any one or any two of them at once).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Speaker selection and source indicators are provided on the attractive dial panel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It&#8217;s a Pioneer value from top to bottom, and your best buy for stereo receiver economy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Specifications<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Tuning range: FM, MW<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Power output: 50 watts per channel into 8\u03a9 (stereo)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Frequency response: 10Hz to 70kHz<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Damping factor: 45<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Input sensitivity: 2mV (mic), 2.5mV (MM), 150mV (DIN), 150mV (line)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Signal to noise ratio: 65dB (mic), 70dB (MM), 95dB (line)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Output: 150mV (line), 30mV (DIN), 1V (Pre out)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Speaker load impedance: 4\u03a9 to 16\u03a9<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Semiconductors: 4 x FET, 4 x IC, 43 x transistors, 24 x diodes<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dimensions: 520 x 175 x 420mm<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Weight: 16.2kg<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Accessories: FM T-type antenna<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Year: 1974<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Pioneer SX-838 AM\/FM Stereo Receiver (1974-76) Description The Pioneer SX-838 is a 5OW RMS stereo receiver featuring PLL FM MPX, precision equalizer, switched-turnover tone control and direct-coupled OCL power amp.
