AX-397 Natural Sound AM/FM Stereo Receiver
High Sound Quality Switchable CD/DVD Direct Amplification Engaged by a front panel switch, it matches CD/DVD signal levels so each stage produces less noise, resulting in improved S/N ratio and maintenance of the amps total gain balance. Super Audio CD and DVD-Audio Ready Rather than the usual 20Hz20kHz frequency response, Yamaha has given the AX-397 the ability to handle frequencies from 10Hz to100kHz (1dB). Although the ear cannot hear the higher frequencies, it has been proven that these harmonics can affect sound reproduction quality. Super Audio CD and DVD-Audio other new formats will be able to output sound over this range, so the AX-397 is fully compatible with products using these formats.
Damping Factor Characteristics
Linear Damping Level variations due to high amp impedance tend to reduce an amplifiers damping factor, and frequency variations cause it to fluctuate. This circuit cancels the effect of these variations, maintaining a high, stable damping factor, for superior articulation of all sounds and better frequency response. High Dynamic Power, LowImpedance Drive Capability Yamaha amplifiers/receivers are capable of delivering large amounts of reserve power for accurate reproduction of high energy peaks. This emphasizes the musics dynamic qualities and provides a sharper sound image. Advanced Facilities Continuously Variable Loudness Control and Bass/Treble/Balance Controls With this control, the midrange frequencies are attenuated over a continuously varying, leveldependent curve, instead of a fixed level of low and high frequency boost as in conventional loudness controls. The bass/treble/balance controls are continuously variable, so they can offer smooth and accurate tonal response control over a wide range. And, with the controls set to their
center defeat positions, you have a perfectly flat tonal balance, with no influence on the original sound. Remote Controllable Motor-Driven Volume Control The remote unit can be used to turn the volume control. The command from the remote activates a motor which moves the volume knob. Because operation is mechanically driven, signal quality is not degraded. Speaker A, B or A+B Selection Speaker A, B or A+B selection lets you listen to either or both of two sets of speakers in two locations. RoHS Compliant This environmentally friendly amplifier fully complies with the EUs RoHS (Restriction of Hazardous Substances) standards. Other Notable Features 6 Audio Input Positions with Tape Monitor Speaker Impedance Selector (6 ohms/4 ohms) Three Switched AC Outlets (UK and Australian models have one outlet.) 2-Way Binding-Post Speaker Terminals (banana*/cable) * Not available on European, Singapore and Korean models Front Panel Headphone Jack System Remote Control Unit

Linear Damping Yamahas Linear Damping maintains a high, stable damping factor even at frequencies from 10Hz to 20kHz, where it generally tends to fall off. The result is superior articulation of all sounds.
