Yamaha CR-840 Owner's Manual page 2

YAMAHA offers you thanks and congratulations on your choice of the CR-840 Receiver.
Embodying the most up-to-date and useful features, it combines superb broadcast reception
with the finest audio quality, and is currently setting new standards for receiver perform¬
ance in its class.
1. All-in-One Excellence
Accurately matched performance specifications,
functions, and controls, provide an overall per¬
formance which fully measures up to Yamaha's
high tuner, preamplifier, and power amp standards.
2
. Noise-Distortion Clearance Range
This is the basic concept for the audio section.
The CR-840 offers an extremely wide range of
output power level for which both noise and dis¬
tortion are below the rated value, to ensure a wide
dynamic range in actual use.
3. Direct Assessment of Differential Gain
This sophisticated technique enables Yamaha to
combine high station-receiving ability, razorsharp
tuning, and ultra-low distortion in the tuner
section.
4. Optimum Tuning System
The OTS system will take over from you the
fine-tuning needed to obtain minimum distortion
and maximum stereo separation, so that all FM
stereo programs are heard at their best.
5. Twin-Meter FM Tuning with Signal Quality
Reading
Both signal strength and center-zero FM tuning
meters are provided on the CR-840, with the signal
strength meter doubling as a signal quality meter
on FM.
8. Comprehensive Tone/Filter Controls
Both bass and treble controls have completely
"FLAT" central positions. High and Low filters
are also provided.
7. Continuous Loudness Compensation
This Yamaha 'special' fully compensates for the
ears' reduced sensitivity to bass and treble
frequencies at low listening levels, whatever your
normal maximum listening level.
8. Auto DX Circuit for High Quality Reception
The Auto DX Circuit permits the IF range to be
automatically modified according to the quality of
the broadcast being received, thereby ensuring
high sensitivity and high selectivity in reception.
