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.

Meridian 551 amplifier


Meridian 551 Integrated Amplifier

Features:

Dual-mono construction

Six adjustable-sensitivity audio inputs

Separate headphone amplifier allows you to enjoy music without disturbing others

High quality MM or MC phono stages available

Preamp audio output using low distortion volume control

RS232 for external control

 


The Meridian 551 Integrated Amplifier uses a dual-mono construction similar to the 556 and 557 Stereo Power Amplifiers but includes a high-quality preamplifier similar to the 501.

The preamplifier provides six audio inputs, each of which can be individually adjusted for sensitivity, and identified on the four-character alphanumeric display. A very high quality MC or MM phono stage is available as an option for the dedicated LP input.

The power amplifier uses a unique feedback topology and precision local error correction system. It is designed and constructed in dual mono format, including a massive twin wound toroidal transformer. A separate headphone amplifier and a speaker on/off facility allow you to enjoy music without disturbing others.
