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.

Musical Fidelity X-P100 pre amplifier

 

X-P100 remote control Class A preamplifier.

The X-P100 is a new model based on our innovative and now very highly regarded Nu-Vista valve preamp but using Field Effect Transistors in place of the Nuvistor valves used in that model.

These transistors were carefully selected from the great many alternatives we tested because of their close similarity in both measured performance and sonic fingerprint to the 6CW4 Nuvistor. We feel that the X-P100 offers a very similar level of sonic fidelity to the Nu-Vista but at the reduced cost afforded by the choice of FET devices.

The X-P100 preamp also features full remote control and a high quality discrete MM phono stage.

 

External Power Supply and  Setting Up

The X-P100 is supplied with an external power supply which is connected to the main unit via an umbilical lead terminated in an XLR/Cannon type plug. This lead should be connected to the socket on the back of the X-P100 main unit.

 

Connections

All connections should be made with the power OFF.

The X-P100 has 5 line level inputs - CD, Tuner, Aux1, Aux2 and Tape, plus an MM phono input. All line inputs are electrically identical and are suitable for use with any source component with an output voltage in the hundreds of millivolts (mV). This includes CD players, tuners, tape machines and the audio outputs of video recorders, televisions, DVD and Laser Disc players etc.

The high quality phono input caters for turntables fitted with a Moving Magnet type cartridge or other cartridges with an output voltage in the range 1 to 5mV.

 

Tape Recording

The X-P100 has a single tape circuit with facilities for off-tape monitoring with 3-head cassette decks.

Connection of your tape machine to the X-P100 should be as follows. The tape machine's Tape/Line outputs go to the X-P100's 'Tape' input sockets. The tape machine's Tape/Line inputs go to the X-P100's 'Tape Record' output.

To record simply select the required source with the source selector knob on the front panel. The selected source will now be sent to the 'Tape Record' output for recording by the attached tape machine.

 

Remote Control

The X-P100 features Infra Red remote control of volume, input selection and mute functions via the supplied remote control handset. The Infra Red receiver is the small red lens marked I.R. situated on the front panel, it is a good idea to place your X-P100 such that there is an unobstructed line-of-sight to this lens from around your listening room.
