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.

Denon DP-A100

 New model of Direct Drive Turntable.  Denon DP-A100.
Special edition of direct drive turntable  celebrating our 100th anniversary.

A History Like No Other.
The history of Denon turntables commenced in 1910 with the production of Japan’s fi rst gramophone and peaked in 1939 when Denon developed a disc recorder for NHK. Denon turntables were used not only by general users but by many radio stations professionals as well. In 1970, Denon developed its own high-torque AC motor for low speeds where speed was controlled by highly precise detection of magnetic pulses recorded around the perimeter of the platter. Denon incorporated this epoch-making servo technology in its development of the direct-drive turntable whose high performance and reliability represented a clear break from conventional idler and belt drive products, and earned Denon a solid position as the brand for players used at radio stations.
 In the following year, the turntable was adapted for consumer use, and Denon, which continued to produce direct-drive players, became an unforgettable brand of analog players among audio enthusiasts. The DP-A100 player is being released as a Denon anniversary model with the same high-performance Denon direct-drive turntable technology that has delivered cogging-free, high-precision rotation for 40 years. Equipped with the DL-A100 cartridge, the DP-A100 is capable of masterfully reproducing the energy and beauty of analog discs.

The Signatures of Quality.
The DP-A100 features the 100th anniversary logo badge, and comes with a 5-year warranty and a signed certifi cate of authenticity from the chief production engineer who hand crafted the product. Also included is the DL-A100 cartridge and a beautiful Denon “brand book” that explores the history of one of the leading names in the audio-visual field.
 High quality audio
• Natural wood cabinet with dark-brown finish The DP-A100’s beautiful cabinet has been made with sliced veneer of natural wood and given a multi-coat finish similar to lacquer to produce a deep glossy lustre.
• Large platter for stable rotation
The DP-A100 has a large die-cast aluminium platter with a diameter of 331mm. Silicone rubber, a deadening material, has been applied over the entire reverse side to minimise vibration and suppress howling.
• Quartz lock servo and direct drive, to support stable rotation
The DP-A100 uses a quartz lock servo that controls rotation frequency by detecting pulses of light passing through a slit inside the motor. This quartz lock servo and direct drive motor work together to ensure high-precision rotation.
• Highly sensitive universal tone arm
The DP-A100’s tone arm is mounted on a large aluminium die-cast base whose height can be adjusted in a range of 6mm. When this tone arm is used with the machined aluminium head shell that comes with the DP-A100, unwanted vibration is absorbed and the cartridge can perform at its maximum capacity.
• Large insulators
Large insulators have been installed on the DP-A100 to achieve ideal damping characteristics against external vibration.
• Included DL-A100 MC stereo cartridge
