Noise is the killer of everything audio & video, and the noise inside your CD player (DVD player, etc) is being generated by the very component which should stop noise, the voltage regulators. The function of the regulator is partly in the name, it ‘regulates’ the voltage, but this is only part of the task. The voltage regulator’s role is also to reject noise (AC ripple) from the unregulated supply and provide a noise free output. The 3-terminal regulators, 7805, LM317, used by manufacturers do a moderate job, regulation is good, rejection of noise at low frequencies (120Hz) average, but they have worsening performance as frequency increases and 1KHz upwards performance slopes off drastically; right through the audio & video band. At the high frequencies, 15-20 KHz this slope off has dropped rejection to a poor 50db. The 3-terminal regulators have poor output noise performance, approx. 45µV noise @ 10Hz to 100 KHz, and steeply increasing impedance at 1KHz upwards.

On-board heat sink for convenient replacement of fixed and adjustable regulators. Advanced, extremely low noise, wide bandwidth closed loop monitoring system. Wideband, post reference noise filter. High Speed, 4-layer design for shortest signal path. Ultra-low noise gain amplifier, 2.1nV/rtHz. 32, high grade, precision Surface Mount Components (SMD).
Gold plated, 140 Micron Copper PCB for reduced skin effect, lowest resistance. High stability under peak current demands.
Size: W = 44 x L = 54 mm. We have a solution, the Invisus 2 is a discretely designed regulator without compromise where individual circuit parameters have been optimised to achieve highest ripple rejection, extremely low noise, fast transient response and very low impedance at high frequencies. Replacing the 78XX & LM317 type regulators in your CD, DVD player, DAC processor with Invisus 2 will remove noise and bring a range of improvements including increased resolution, improved detail & clarity, better dynamics, faster, tauter bass, improved stereo separation. Stop noise in your system and start hearing more music!
