MPower SSL4000 Series PSU-1-56 Input MPower

Mpower console power supplies utilise the latest switch mode power modules coupled with proprietary filtering circuits that result in a very compact 3U unit that is cool running and highly energy efficient.

As a consequence, one unit will replace two SSL CF616E power supplies and the CF663 changeover unit.

It no longer needs to be housed in a separate air conditioned room as it does not need assisted cooling and furthermore, because of its very low ambient noise (much quieter than a computer for example), it can be sited in the control room. This results in the ability to use much shorter power supply cables which significantly reduces the voltage losses incurred by long cables.

Not only is there a saving made in electricity usage by not needing a dedicated air conditioner, significant savings in the main electrical supply can also be made owing to their much superior energy conversion, (typically 85 percent as opposed to only 35 percent from the original linear supplies).

Tests have shown that on a 64 channel SSL 4000G Series console, the electricity consumption was reduced from 1.8kW to just 0.8kW. So apart from the increased reliability and low ambient noise, electricity bills can be more than halved. Effectively therefore, the price of the Mpower unit can be paid for in around a year or so!

Mpower console supplies have been designed by Professor Malcolm Toft, whose career has spanned more than fifty years in the recording industry. As recording engineer he worked with The Beatles, David Bowie, James Taylor, Joe Cocker and T-Rex among many others. He then went on to found Trident Audio developments, a major manufacturer of recording consoles during his ownership from the early 1970’s to the late 1980’s. He still has the same passion for designing equipment that has driven him throughout his illustrious career. In 2010 he was made a Visiting Professor at Leeds College of Music in recognition of his contribution to the recording industry. He is well aware how important reliability is to studio owners and for this reason he has spent a considerable time researching the design of the Mpower supplies to ensure that reliability is a key factor.

Key Features:

The design incorporates a number of unique features not typically found in any other console power supplies.

Red digital displays show the voltage on all of the d.c. outputs feeding the console and blue displays next to them show the amount of current being drawn on the main audio and logic rails.

The current displays are particularly useful in showing that the current drawn by the +/- audio rails is equal.

A standby switch, separate to the mains power switch isolates the d.c. outputs from the console (apart from phantom power). This provides a quick and easy way to disconnect the console from the power supply while setting up voltages etc. It also allows the power modules to achieve full voltage without the console load. This means that if required, the SSL bucket switches can all be left in the ‘on’ position.

Cross coupling of the +/- audio voltages is also provided whereby, if one supply rail should drop out for any reason, the other supply rail will automatically be disconnected.

The supplies have been designed in a modular fashion whereby in the unlikely event of a power module failing, it can easily be replaced with all connections being made by screwdriver terminals.

The rest of the circuitry is incorporated into a single printed circuit board which is again connected by screw terminals and can be removed for servicing or replaced if necessary.

A key emphasis in the design has been to make sure that the supplies run as cool as possible yet produce the minimum amount of ambient noise. This has been achieved by making sure that the power modules run well within their maximum capabilities and the inclusion of specially selected ultra low noise fans.

The unit will run on mains a.c. voltages ranging from 85-260volts without any selector switches being necessary. This means that it will operate in all countries worldwide.
