Natural Sound AM/FM Receiver (1979-81)

Description

The Yamaha CR-640 is designed for easy operation.

Note, for instance, its clean three-tiered front panel design; the tuner scales, frequently used important switches and controls, and all other auxiliary devices are arranged on three different eye levels, so you can concentrate on enjoying music instead of fussing with controls and switches every time.

A number of unique features also add to easy operation, such as the Rec Out Selector for instance, which lets you choose any program source to record into your connected tape deck, while you listen to any other source.

FM/AM tuning is also made exceptionally easier in the CR-640, but reception quality is first-rate all the way.

As you would expect of a quality hi-fi component, the CR-640 comes in a beautifully crafted, sturdy wooden cabinet to blend with any decor.

It is finished in handsome, simulated ebony veneer, and matches Yamaha\'s other fine stereo components.

The CR-640 assures you of quality FM reception, regardless of the signal condition.

The built-in AUTO-DX circuit detects the signal strength and the amount of interference present, and, if necessary, automatically chooses the DX Mode IF Stage to increase the selectivity to 83dB.

Weak signals from a distant station are rid of all interference and clearly reproduced, and whenever the DX Mode IF Stage is in operation, the built-in Auto Blend Circuit is also automatically activated to enhance the high frequency signal-to-noise ratio.

On the other hand, if the signal strength is sufficient and there is little interference, the LOCAL Mode IF Stage is chosen to hold distortion very low for outstanding hi-fi tonal quality.
