What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Onkyo P-3000R


Two-Channel Pre-Amp Delivers Sublime Audio
Despite being at the cutting edge of the burgeoning home theater market, Onkyo has never forgotten its roots in pure hi-fi audio. With the P-3000R, we present a streamlined two-channel pre-amplifier that packs a treasure trove of stunning audio technology. The P-3000R handles both analog and digital sources, with connectivity options including AES/EBU digital connectors and a USB device for PC audio. Separate 192 kHz/32-bit TI Burr-Brown DACs for each channel ensure accurate digital-to-analog conversion. Meanwhile, to minimize interference and maintain signal quality, the P-3000R employs noise-reducing DIDRC technology, a vibration-resistant chassis design, and independent amplifier circuitry. Thanks to the P-3000R’s bi-amping capability, you also have greater flexibility in how you set up your system. As always, the job of all this advanced hardware is to bring you closer to your music and let you feel the unique resonance of each individual instrument.
