Reference Level DC Power Supply with ARC6 DC4 module and DC4 regulator with CX filter section for low current outputs
NOW AVAILABLE TO ORDER - THE MINI ARC6 DC4 PSU!
Due to popular demand, we are now delighted to offer our ARC6 DC4 architecture in a more conveniently-sized case!
This is a slightly simplified version of our best-in-class ARC6 DC4 PSU - we still use the same ARC6 module and DC4 regulator module as the full-spec ARC6 DC4, but we use a smaller transformer to fit within the limitations of the compact casework and we also have to remove some of the vibration-damping features. We still keep the gold-plated Furutech IEC socket with separate DC4 power switch, grounding post and Neotech ICC internal DC wiring (with the same option to upgrade to Mundorf silver-gold wire if desired) and DC4-spec umbilical cable. Essentially you are getting a ARC6 DC4 electronics inside a DC3 case, at a lower price than the full ARC6 DC4.
The ARC6 module uses active rectification, over 198,000uF of reservoir capacitance (five times that of the old RECAP module) and a high-current choke to eliminate any residual noise before it feeds into the regulator modules. We also offer upgrades of the DC wiring - the standard wire is 18AWG Neotech OCC wire, you can also have Mundorf's excellent silver-gold hybrid wire fitted in either 18AWG or 15AWG sizes. The 15AWG option allows for a lower supply impedance. We can make the umbilical cables to any desired length, we do suggest a shorter cable is better for performance.
Due to the custom manufacturing of each mains transformer to suit your bespoke requirements, there is a lead time of typically 4-5 weeks for the transformer plus 1-2 weeks for PSU construction once the transformer arrives. The Mini ARC6 DC4 case is the same size as the DC3 case, at 290mm long, 230mm wide and 95mm high (including feet). Note that the Mini ARC6 DC4 has one DC output - it is not possible to add extra outputs to this PSU.
SPECIFICATIONS:
All-aluminium casework, 240mm wide by 290mm deep. Case height is approximately 95mm including the feet.
Furutech gold-plated IEC inlet for mains AC supply (as with all of our PSUs, an IEC cable is not supplied with the Mini ARC6 DC4), a rear panel mains power switch is normally included but can be omitted if desired.
Custom-made audio spec toroidal transformer with multiple shielding layers.
Full-spec ARC6 module with ARC6 choke - active rectification, 198,000uF of Mundorf reservoir capacitance, audiophile V-CAP filter capacitor
The entire DC wiring loom is made using Neotech OCC wiring with PTFE insulation - all expertly routed and bound with our usual high levels of attention to detail. A neatly bound cable loom reduces noise due to current loop areas as well, so it brings a sonic benefit as well as looking nice!
The DC4 regulator module also contains our new "CX" module - this acts to drastically reduce incoming DC noise from the reservoir capacitors, by factors of up to around 1,000 at low currents. The module has an approximate limit of 2A though, at which the noise reduction factor becomes close to 1, and so the DC4 regulator module has a link which allows the CX module to be manually bypassed if the output is supplying more than 2A of current. This link can be set at time of manufacture to your requirements, and can be changed by the user in the future as well (involves removing the top cover and moving some small link plugs).
DC4 regulator modules can supply up to 5A continuous current as standard, unlike the DC3 design which required a separate boost module.
The DC4 regulator PCB, like the rectification/capacitor PCB, is also gold-plated, and the circuit layout is completely optimised for performance, low noise and low impedance. This is due in part to using different components that allow shorter circuit paths to be created, with lower parasitic inductances/capacitances.
The new DC4 regulator design uses the very best components - we use a full set of Vishay Z-foil "naked" resistors for the regulator section, and extremely low noise resistors for the (non-critical) CX section and for one filter network of the regulator itself. We also now use Vishay bulk film capacitors for all decoupling duties, as well as some very special Audio Note KAISEI capacitors for all the important regulator module capacitors. These are a relatively new capacitor, designed by the same team behind the legendary Black Gate capacitors. The CX module section uses the same Nichicon FG "Fine Gold" capacitors as the DC3 design, as we found that the KAISEI capacitors made no noticeable difference here.
The DC4 is supplied with output cables to suit the client's requirements where possible, DC4 cables are made from Neotech OCC wire with PTFE insulation just like the internal wiring, and are fitted with Oyaide gold-plated DC connectors for those that require tube-type plugs with a 2.1 or 2.5mm inner hole. Other connectors can be fitted for any other devices, depending on availability of suitable parts.
