![]() ![]() The SugarCube runs on the Debian 8 (Jessie) linux environment and runs a proprietary algorithm which, instead of identifying frequencies or bands of audio with problems as would a primitive noise reduction solution, looks for events in the time domain and removes them by interpolating the slope of the preceding audio. The SC-1 incorporates 24-bit, 192kHz analogue to digital and digital to analogue converters. There’s a great deal more going on inside. Pressing the Pair button displays a four digit pair code on screen which is entered into the app, a process that needs to be completed only once. There’s also a Pair button for pairing the SC-1 with the SugarCube app for iOS and Android. The unit is powered externally by a 12V, 2A power brick for which there is an associated connection and power switch. I discovered quite by accident that 25 mm Sorbothane hemispheres are a perfect fit for the feet once the O rings are removed, providing a further level of isolation to the unit against external vibration. They can easily become dislodged and lost if the unit is relocated. My only build quality gripe concerns the feet, the rubber protectors of which are o rings pressed into grooves in the foot. ![]() Around back are sturdy gold-plated RCA jacks for input and output, an RJ45 LAN connector and USB for the supplied wifi adapter. A sparse front panel hosts buttons for Click Remove, Click Mon and Bypass, with a strength knob and status display. Even Marantz later had a go in the mid 90s with the SX-72 scratch suppressor, though by then vinyl sales were reaching their all time low as the compact disc took over.įirst impressions of the SC-1 are of a sleek, understated component with a minimalistic appearance, available in either a silver or black anodised chassis. You can read a white paper on the system Here. The SAE 5000 Impulse Noise Reduction system was a digital device based around a 68K Motorola CPU and had an algorithm that analysed the signal for fast-attack, short-duration, out-of-phase signal elements. It did so with some success, though it was a destructive process and is vastly inferior to even the most rudimentary digital solutions. It was a magnetic phono preamplifier with a scratch reduction circuit designed to remove the noise associated with fairly significant scratches on LP records. Garrard’s MR101 Music Recovery Module was released in 1978 towards the end of the brand’s heyday in the consumer market. The SugarCube isn’t the first device intended to de-crackle vinyl in realtime. The SweetVinyl SugarCube aims to fill that gap. Removing vinyl noise in realtime is no easy task however, and to do so in a non destructive way has until now been nigh impossible. Clicks, pops and crackles can mask detail and distract from the music, and there’s no doubting that a clean, quiet disc is always preferable to a noisy one. Noise can however detract from the listening experience, particularly if a record has significant wear or is to be digitised for archival purposes. The sound of a worn record crackling softly as it revolves beneath the stylus can actually be quite pleasant, like the crackle of a fire on a cold summers evening. We all know that pops, clicks and crackles are all part of the vinyl experience.
