High performance Direct Access Receiver with VCR capability
Features
Direct Access quartz frequency synthesis tuning
Audio-Video control center for easy connection with video equipment
Legato Linear amplifier circuitry
Key Selling Feature Audio-Video control
The integration of audio and video equipment is finally a reality. Stereo video-cassette recorders, stereo videodiscs and monitors are taking their places beside audio equipment. The STR-VX450 provides your customer with connection facilities for all these video systems. You can hook up two video sources, such as a VCR, videodisc, or monitor TV. Plus, you can even dub from one VCR, to another. The advantage? High fidelity sound. Not the flat, lifeless sound normally associated with video. Your customers obtain it simply and easily through the STR-VX450.
Key Demonstration
Assemble the most complete audio/video system possible Demonstrate a stereo video-cassette or videodisc with the Sony receiver and a pair of separate speakers. Make sure to pick an impressive program. Point out that the consumer needs this type of hookup to appreciate the full benefits of the video sound source. A/B with video playback through mono television speakers.
