TX-SR703 THX Select2 7.1-Channel Home Theater Receiver
 

As the latest incarnation of one of Onkyo’s most popular receivers, the THX Select2 Certified TX-SR703 looks set to excel in the mid-range category. In keeping with its impressive legacy, the TX-SR703 boasts high-grade parts and immaculate construction, along with the ability to integrate effectively with the latest high-definition displays, playback components and high-quality speakers. The key words here are “power” and “precision.” Power, at a robust 100 watts per channel, enough to drive virtually any speaker is combined with precision from our VLSC (Vector Linear Shaping Circuitry) that produces a virtually noise-free signal from all your movie and music sources. Other functions, like crossover adjustment from 40 Hz to 200 Hz with 10/20 Hz steps and speaker placement calibration with Auto Speaker Set-up with Microphone, accurately deliver the low frequencies and enveloping sound that recreate the floor-quaking impact of the cinema, right in your own home.
