The chassis is black powder coated aluminum as is the base.
Transformer based volume control. The transformer volume control transformer volume controllers tvc s are arguably a step up from stepped attenuators pardon the pun. 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 new revision for the new tvc version. The preamp generates gain that s completely redundant in the context of high output digital sources hi gain amps and reasonably efficient speakers.
A transformer volume control s different as you turn it down its current output capability goes up and its output impedance goes down and that is a good thing. It helps preserve low level details tone dynamics and allows it to drive cables shit better. Tvcs abandon resistive materials altogether and use transformers to convey and throttle the audio signal electromagnetically. Passive transformer volume control.
Improved transformer winding. Audion select tvc1 transformer based volume control passive line level pre amplifier is hand built with quality compononents. It connects between the speaker level output of an amplifier receiver or speaker selector and a pair of speakers. This brings about more weight and prat to the music.
Speakercraft vst60 transformer based stereo volume control w liftlock connectors asm17141 brand. Pictures above are for the tvc balance. The rationale for tvcs transformer based volume control is that traditional attenuation in active preamps is a matter of loss. Technical overview inductive controls as a category covers both transformer and autoformer based designs.
Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers for example in a joystick. Most people report that the autoformer has such an open effortless sound that they would not consider going back to a resistive device. 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.
And it s not a subtle difference. 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. The top plate is mirror finished stainless steel. New the speakercraft vst60 is a wall mounted stereo volume control.
