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.

Krell KAV-300iL amplifier

Integrated Amplifier

The Krell KAV-300iL integrated amplifier is power and control in essential form. Delivering exceptionally musical sound reproduction and an operational elegance matched by few components at any price, the KEV-300iL, is an ideal component for music enthusiasts seeking quality, performance, and convenience.

With power output of 200 Watts per channel into 8 Ω   and 400 Watts per channel into 4 Ω , the KAV-300iL has tremendous power reserves and provides high dynamic headroom. Even the most demanding source material is thus reproduced with decided authority and transparency.

The preamplifier section features Krell's advanced Class A, direct-coupled circuitry for superbly detailed music reproduction. Preamp circuits are powered by a dedicated supply with discrete voltage regulators.

The power amplifier section incorporates proprietary Krell driver and output transistors. 12 devices per channel provide enormous output current capability - far beyond that of typical integrated amplifiers.

The gain stages use Krell Current Mode discrete Class A, direct-coupled, fully complementary circuitry, further ensuring a level of reproduction quality normally associated only with the most expensive separate components.

Both balanced and single-ended inputs are provided, and Krell's Theater Throughput mode simplifies integration into home theater systems. A convenient full-function handheld remote control is supplied. The KAV-300iL thus complements superb sound quality with outstanding operational ease and functional versatility.

The power supply features a massive 800 VA toroidal transformer. Extensive power supply filtering and decoupling between stages assure low noise and high stability.
