FULLY REGULATED Linear power supply for chord hugo m scaler
- 15V FULLY REGULATED DC OUTPUT
- DESIGNED SPECIFICALLY FOR THE MSCALER
- AWARD WINNING DESIGN
This new power supply has been specifically developed for the new Chord Mscaler. We do NOT sell the Mscaler.
The new Chord M Scaler requires 15V DC input, whilst there are discussions about power supplies not affecting the performance of products we beg to differ. Most of the time you are listening directly to the effects of the power supply for your chosen equipment. That is why a fully regulated linear power supply is so popular because it transforms the sound quality to something far far better, proven by 100’s of existing customer comments / feedbacks. ALL our power supplies come with a 30 day money back guarantee, if you cannot hear an improvement return it for a full refund. Suffice to say we get very few sent back.
The MCRU linear PSU is a plug and play device, fitted with the correct sized DC plug to fit the M Scaler and a power cord to suit your country (UK | EU | USA | AUS ) simply attach the cable to the M Scaler and plug the power cord into the mains and relax. Based on a multi award winning design the power supply consists of 2 cases, the larger case can sit next to your equipment or behind your rack, the smaller case needs to be as close to the powered equipment as possible.
If you live outside the UK simply place your order and we will supply the correct power cord to suit your country with the correct input voltage.
The power supply is available with a silver or black case.
2 versions are available, standard and up-graded, the up-graded version has the following enhancements fitted………………
Kimber cable from small case to DC connector
Furutech gold plated IEC inlet
Hi-Fi tuning fuse with cardas copper end caps
IsoTek EVO3 Initium mains lead (1.5 metres long)
The design thoughts behind the 2 box PSU are below.
When thinking of regulation, it’s worth remembering the Roman god Janus. Who was the god of gateways, and was a two faced god looking in both directions. Likewise a good voltage regulator is required to look in both directions at once. From one direction you have the mains supply, with the ever increasing noise, distortion and random variation that exists on our household mains supply. In the other direction you have the device you are supplying power to. The load will be asking constantly varying current, and the job of the regulator will be to ignore the varying load and to supply a rock steady voltage that ignores the changing load.
To ask a single regulator to perform both tasks means that it can not do either as well as it could. We don’t ask our regulators to be two faced, we split the two functions into two separate regulators and put them both where they can do the best job.
The first regulator is close to the mains supply, its job is to take the incoming mains and convert it into a low(ish) noise DC supply, and to isolate the mess that is our household power lines from what follows. In most power supplies on the market, the output of the first stage would be directly connected to the load device, and that would certainly be an improvement over the supplies that most manufactures provide. But we can do better by adding the other face of Janus to the system.
The second regulator is supplied with a clean low noise supply, and its job is to handle the changing demands of the load. To do that, it needs to be as close to the load as possible. So we remove the second regulator from the main box, and place it close to the load, both electrically and physically, that removes it from the noise and interference of the mains supply, and allows it to spend its time looking towards the load. Typical commercial voltage regulator chips are general purpose devices, but are not quiet enough for the task on hand, so the second regulator uses a bespoke regulator based on a low noise multi stage filtered voltage reference, a low noise error amplifier and a high current low resistance mosfet. To allow it to handle the changing load it also needs to supply current on demand, so all the remaining space in the second regulator is filled with low impedance capacitors to act as a local energy source.
Using the two stages of regulator, we achieve a noise floor equal or better than most battery supplies, and an effective source resistance of the order of 0.02 ohm (and the short cable run to the load avoids increasing this value by not adding copper where its not needed), and the use of a discrete regulator design allows that tiny value to be maintained way above the frequency that any audio device operates at.
