Transformer Based Volume Control

Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.

Transformer based volume control. It helps preserve low level details tone dynamics and allows it to drive cables shit better. It connects between the speaker level output of an amplifier receiver or speaker selector and a pair of speakers. Most people report that the autoformer has such an open effortless sound that they would not consider going back to a resistive device. It turns out that such designs were first patented during the early radio years in the 1920 s but otherwise lay dormant for many years due to cost considerations except for a foray by luxman in the 1980 s.

New the speakercraft vst60 is a wall mounted stereo volume control. Audion select tvc1 transformer based volume control passive line level pre amplifier is hand built with quality compononents. The chassis is black powder coated aluminum as is the base. This brings about more weight and prat to the music.

Potentiometers operated by a mechanism can be used as position transducers for example in a joystick. Passive transformer volume control. 2 product ratings atlas sound lp at100d 100w auto transformer speaker volume control decora style 26 99 trending at 27 79 trending price is based on prices over last 90 days. The rationale for tvcs transformer based volume control is that traditional attenuation in active preamps is a matter of loss.

Improved transformer winding. Tvcs abandon resistive materials altogether and use transformers to convey and throttle the audio signal electromagnetically. The top plate is mirror finished stainless steel. Technical overview inductive controls as a category covers both transformer and autoformer based designs.

For normal listening most that gain needs to be strangulated. The transformer volume control transformer volume controllers tvc s are arguably a step up from stepped attenuators pardon the pun. The new revision for the new tvc version. And it s not a subtle difference.

A the simple answer is that most people find that the autoformer volume control sounds significantly better than even the best potentiometer or stepped attenuator. The preamp generates gain that s completely redundant in the context of high output digital sources hi gain amps and reasonably efficient speakers. Improved chassis rigidity by using a top and bottom stainless steel plates. Audion silver special edition transformer volume control passive pre amplifier with 6db gain.
