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.

Myryad MI-120 amplifier

The Myryad MI 120 Stereo Integrated Amplifier has been designed to offer a combination of high quality sound reproduction and elegant styling.

The amplifier can accept up to six line-level input sources, including two tape recorders. Outputs are provided for one pair of loudspeakers and for headphones. All functions – input selection, volume and standby – can be operated using the infra-red remote control handset.

The MI 120 offers a range of expansion possibilities:

- The AUX. input can be converted to accept the output from a phono cartridge by installing a Myryad Phono Cartridge

Pre-Amp Module.

- A low-level “Bi-amp” output is provided to feed the Myryad MA 120 Power Amplifier, allowing bi-amplified drive of suitable loudspeakers.

- The “My-Link” input/output can be coupled to other Myryad products which can then be remote-controlled via the MI 120’s infra-red receiver.
