The only compact disc player with separate power supplies for each critical performance
function.
The Onkyo Integra DX-300
Servo Control Delta Power Supply--Powers the FOUR DC and DC Servo motors and control circuitry, ensuring smooth and stable transport action. This design provides accurate disc rotation with positive disc handling and loading.
Analog Domain Delta Power Supply--The important analog circuits benefit from the clean DC source, ensuring that the analog audio output retains the full dynamic range capabilities of the digital compact disc.
Digital Domain Delta Power Supply--Provides the digital microprocessors and Digital/Analog conversion circuitry with a rock-steady DC supply. This ensures that transient voltage spikes and modulation noise cannot interrupt the digital data bitstream.
Display Delta Power Supply--Energizes the incandescent, fluorescent, and LED components of the front display panel, with constant illumination.
The parameters of the Digital Audio Disc system provide for incredible audio performance, with wide dynamic range and ultra low distortion. Because Compact Disc players deal with purely digital audio signals it is commonly believed that no differences in sound quality exist between various CD players. However, much of the circuitry is devoted to the musical information after conversion to analog form.
The Onkyo DX-300 Compact Disc Player employs separate Delta Power Supplies for each critical performance function to ensure that no extraneous noise or distortion affects the musical performance.
The Delta Power Supply, developed by Onkyo and used in our state-of-the-art amplifiers, pre-amplifiers, and other audio components, eliminates the low-level transient modulation noise caused by the interaction of musical signals with frequency components at or near the line charging frequency. This expands the available dynamic range a full 20 db over conventional analog power supplies, and provides a supply source with a dynamic range wide enough to match that of the digital audio source.
Onkyo's patented Delta Power Supplies, coupled with a highly sophisticated laser tracking system and the most demanded convenience features, ensures that superb audio fidelity will always be realized. As the name "Integra" suggests, the DX-300 gives the listener a sound that's as close as possible to the original, with all the integrity of the live performance retained.
