True, it's tempting to be swept up by our power.
150 watt's per channel minimum RMS at 8 ohms, from 20 Hz to 20 kHz, with no more than 0,07% Total Harmonic Distortion , is nothing to sneeze at.
But raw power means nothing. What's important is how that power is delivered. In the case of the STR-V7, it's brought to you by Sony in a very classy package.
You get a combination of features and control that are impressive on their own - but almost unheard of in a single machine. To start with, we've built in a Dolby system, for decoding Dolbyized FM broadcasts. The advantages of our tuner, though, need no decoding. They include a normal and narrow FM IF bandwidth selector. It makes life simple for people in areas where their signals are crowded together albow to elbow.
In our preamp section, the V7 comes equipped with a special phono EQ circuitry. Thanks to Sony's high IQ, it allows for direct connection of a low-output, moving-coil cartridge phono source. Without calling for an external step-up transformer or pre-preamp.
When you're gifted with as much power as the V7, you need a way to keep track of it. This receiver keeps table with two power output meters, monitoring the power being fed to the speakers. So overload can't result from oversight.
And all that power comes from our direct coupled DC power amp. And our power is stable, thanks to a high-efficiency, high regulation toroidal-coil transformer.
There's a lot more to the STR-V7 than power. This receiver takes the best that contemporary technology has to offer, and offers it in a single machine .
Other manufacturers may have the power to bring you power. But only Sony has the power to bring you more than just power
