PURE DIRECT SWITCH
For the ulitmate in signal purity, you can engage the Pure Direct Switch, causing the signal to bypass the tone control circuitry.
HEAVY-DUTY TOP- ART BASE
To support these heavy components and prevent vibration and resonance, Yamaha has a special base inside the chassis. It has a double panel structure, each 1.6mm thick, and the AX-490 adds extra damping material between the two panels.
GOLD PLATED CD INPUT JACK AND CD TERMINAL
Because gold is an excellent conductor and not susceptible to corrosion, this unit has gold-plated input terminals. The AX-490 goes a step further, with 2-pin gold-plated solid brass CD and Pre Out terminals for large-size cables.
3-WAY BINDING SPEAKER TERMINALS
Banana plug compatible on all channels. Permits the use of a variety of speaker wires and connectors.
29 KEY SYSTEM REMOTE CONTROL
Allows you to control the major functions of other Yamaha system components such as a CD player, cassette deck, tuner or turntable, from the amplifier's remote control.
LINEAR DAMPING FACTOR CIRCUIT
A high, stable linear damping factor means plenty of ability to stop the speaker cone from vibrating when the signal stops. It also cancels the effect of level variations due to high amp impedance. The result is clear, crisp, pure sound and significantly improved frequency response.
