Upper range power output, unusual FM selectivity and sensitivity and the versatility of units costing much, much more - the SX-727 stereo receiver from Pioneer puts together all of these hi-fi virtues and offers the music enthusiast a new high in stereo valve. verSatility is the keynote of this attractively-designed unit. The SX-727 handles up to two tape decks, two turntables, three pairs of speaker system and a microphone. Its sensitive FM section is loaded with the very latest of solid state circuitry - the better to offer distortion free reception. Its direct-coupled power amplifier circuitry means a wide power bandwidth and superb frequency response. And the unit puts out up to 195 watts of music power (at 4 Ω ), more than enough to fill a large room with great sound. Now available at a price that is as surprising as its many features.
