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.

Cambridge Alva TT turntable


Rather than go for a Belt Drive system with the ALVA TT, we opted for a medium-torque Direct Drive. Over time, the elastic used on a Belt Drive turntable can stretch and will need to be replaced. As a result of this wear, Belt Drive turntables traditionally have a less accurate playback speed than their Direct Drive cousins. This isn’t a problem on the ALVA TT – it has just 0.06% Wow and Flutter. This means a far better pitch stability – particularly during longer, more sustained musical notes.

The Alva TT uses a classic British-made one-piece tonearm. There are no joints, giving it the best possible grounding for the cartridge and offering extremely low friction.
It’s designed to retrieve the maximum amount of sonic detail from the cartridge and therefore your records.

Bluetooth aptX HD liberates your record player from the hi-fi rack. With the freedom to place Alva TT anywhere you like, your records are invited into the lime-light. Your music can be streamed from Alva TT to any Bluetooth receiver at up to 24bit/48kHz Hi-Res, which means you’re guaranteed an authentic vinyl experience, wherever it’s placed.
