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.

Creek 4240


The Creek 4240 is an Integrated Amplifier of the highest caliber, designed and manufactured inthe U.K. The 4240 employs exclusive and novel circuit techniques believed by its elegantly simple appearance. The 4240 is the new benchmark for integrated  sound and value. With the 4240, Creek engineers used CAD (Computer Aided Design) to update the classic Creek 4040 and 4140. You have complete control of your system through four line inputs plus a tape loop. A high quality Creek phono stage (MM or MC) is an optional add-on for playback of conventional records.
External connections for access to the preamp or power amp stages provide unique possibilities. You can bi-amp your speakers by adding the matching Creek A42 power amp. Two pairs of  4 mm speaker sockets provide switched output when headphones are used, or direct output.  Jointly, the double connections make bi-wiring extremely convenient.

The superior sound quality of the 4240 comes from numerous design techniques including DC coupling of its preamp and power amp. This is achieved by removing all sound degrading capacitors from the signal path and using advanced DC servo circuitry. MOS-FET driver and output power transistors insure a high level of performance and reliability not found at this price.
With the 4240 Creek continues to prove that accurate, full bodied sound can be truly affordable.
