Description How-to
 
The Audiomagus PowerCenter™ SLA Battery Power Supply is the first in our family of integrated 12VDC power products. We have done everything we can to ensure the purest, quietest 12VDC power for your audio components.

Housed in elegant, but unobtrusive, low-profile black anodized aluminum the PowerCenter will easily find a home on your audio shelves. Designed for easy and safe battery access, the UL and CE certified 3-stage charger and the AC entry are fully shielded by 24 gauge anti-corrosion treated and painted sheet metal.
  • The PowerCenter Battery Unit is hand-wired and uses high-quality

    Tighter and deeper bass, clearer midrange, smoother and more extended highs, more unforced detail, quieter backgrounds, and a more 3-D soundstage... Wow!

    connectors, WBT 4% Silver Solder, and the shortest possible runs of 18 gauge, silver plated copper premium wire.
  • The UL & CE certified 3-stage charger will easily charge batteries up to 8AH in less than 8 hours. AC fuse protected. Red and green LEDs indicate state of charge. (Red for charging and green for charged or idle.)
  • With an eye to ease of use and an ear to ensuring the very best sound, switches are front-panel-mounted and use solid silver-plated copper contacts
  • The PowerCenter is designed for maximum in DC separation from noisy AC mains power.
    • One switch controls the AC connection to the charger, while the other switch toggles between charger and amp. You can never connect the amplifier to the battery when the charger is connected! For an extra measure of isolation you can use the second switch to disconnect from AC power.
    • AC wiring is isolated to the left side of the enclosure while DC is on the right side; the battery is in the middle.
    • Front and back connections are shielded on the interior by sheet metal.
  • Each PowerCenter includes an 8AH SLA battery. If fits the case nicely and provides over 20 hours of musical pleasure. (If you have a local battery source, we also offer the PowerCenter without battery so you can save on shipping.)

Battery
The PowerCenter BPS uses a Sealed Lead-Acid (SLA) battery. It is valve-regulated type (sometimes called ‘sealed’ or maintenance-free) and uses an absorptive fiberglass mat to hold the acid electrolyte. The advantage of this design is that the battery needs no water additions, can be operated in any position, and can be used in close proximity to people and sensitive equipment.

Immediately improved the Trends TA-10.1 February 29, 2008
Reviewer: B. Gravanis from Atlanta, GA  
I rotated the PowerCenter into my Trends-based desktop system and auditioned the changes in a very finicky "nearfield" setup.  The results confirmed what many have said about the sensitivity of T-amps to their power supply.  The situation was by no means bad before, but the battery supply yielded a dead quiet blackness from which music issued forth.  A new clarity was apparent in _all_ of the standard test pieces that I tried.  In short, feeding totally pure 12VDC from this well-designed battery system made the amp really come alive.  A perfect match!
