Balanced Power BMU-2500
In a typical home electrical system, the power supply is “unbalanced”. This can be susceptible to noise and interference from various sources within the home's electrical system, inducing it into high-grade, sensitive electronics.
See our Balanced Power information page for a further in-depth explanation.
A Balanced Mains Unit uses a transformer to split the incoming AC voltage into two symmetrical, out-of-phase voltages, effectively creating a "balanced" feed of power. This balanced configuration is designed to cancel out noise resulting in a cleaner power source for sensitive audio and visual equipment.
While balanced power can offer significant benefits, it's important to ensure the quality of the overall balanced power supply design. Our Balanced Power BMUs utilise a bespoke wound high quality custom toroidal transformer from renowned manufacturers Toroidy.
Even in the most severe of situations our BMUs offer a consistency of performance that will have your system operating at it’s very best, any time of the day or night. Expect far greater timing capabilities, phase control and increased micro-detail retrieval, within a greatly improved and sizeable soundstage conveying exceptional realism and dynamics.
Our balanced mains units will not damage the musicality of a performance, such as some filters and conditioners can do, by damping dynamic freedom and recessing midrange three-dimensionality. In fact, our BMUs with therer premium selected parts will improve musicality and naturalness, allowing for increasingly longer listening sessions without fatigue.
Construction
Inside our thick aluminium chassis is a range of high quality and specifically chosen for premium components. We use only the highest grade circuitry to clean up noise from the incoming mains supply and maintain the quality of output.
Our design champions a short and clean signal path, with all connections to each socket configured in a star formation, allowing for full unimpeded power output to any individual socket. Our star earthing arrangement and ground access on the rear panel via a 5 way 4mm binding post offers users a reference grounding point, which can eradicate detrimental system earthing loop issues promoting an even lower noise floor.
The rear sockets are chosen specifically for their tight fit and ultra-low resistive properties. Each socket has a spring loaded cap which snaps shut and protects the sockets from dust and moisture when not in use. Each socket is mounted with a laser-cut rubber decoupling gasket to minimise vibration.
Our choice of a silicone dielectric for the high purity copper voltage cables reduces vibration and static. The silver plated copper, teflon coated earthing loom goes through a treatment process to remove static prior to install creating a high speed route to earth, reducing system noise even further.
As well as having a very inert and dampened chassis, each Balanced Power BMU comes with a set of specifically engineered equipment feet. These feet comprise of two CNC’d discs of a specially formulated Aluminium Polymer Compound (APC) which deals with micro-vibrations far more effectively than its aluminium counterpart. Sandwiched between these two APC discs are ceramic ball bearings; an excellent medium to convert vibrations into heat.
DC Blocking
All our BMUs incorporate a sophisticated DC Blocking circuit. DC Blocking allows transformers to work at their optimal performance. Eliminating hum, so that they can effortlessly run at their full power potential without being choked by harmful DC. Not only will this circuit enhance the background quietness of your listening sessions - it will also, in conjunction with the specially designed transformer isolate your equipment from the mains electrical ring in your home which generates a lot of DC.
Further Lowering of the Noise Floor through Attached Power Cables
A balanced power supply reduces radiated fields from power cables affecting signal cables by using two out-of-phase voltages, which causes the magnetic electrical fields to cancel induced EMI.
Any reactive currents (common-mode currents) flowing in the two wires will also be inversely phased. At the central earth point, these equal and opposite currents will cancel each other out, rather than being superimposed on the earth.
Safety In Mind
Protecting you and your equipment is of paramount importance to us, yet choosing safety features which are beneficial to overall sound quality can be a challenge. The use of MCB type trip switches, typically found in consumer units and other balanced mains units are certainly not specified for audio usage. Multiple fuse rails are suitable, however if one rail blows there is still live voltage on the other to consider, which in extreme cases could still result in deadly harm.
Our safety protection covers every wire and piece of equipment attached to our BMUs, meaning if there is a fault on any part of the outputted electrical signal the entire array of balanced outputs will shut down instantaneously protecting you and your equipment. We protect our balanced outputs with an high quality trip which has gold plated PCB tracks and connections along with high-grade magnesium relays to ensure the integrity of signal output.
Extended Component Lifespan
In addition to the sonic and visual benefits of our BMUs, another fantastic reason to consider adding one to your setup is their ability to prolong the lifespan of your systems components. Our BMUs will reduce heat on circuit board mounted components, stop transformer hum, lower noise and remove harmful DC; thus promoting an extended lifespan of attached components, resulting less frequent servicing schedules or component failures.
