SPECIFICATIONS

Location:

Because its Toroidal transformer design minimizes stray magnetic fields, the M-8x AR may be positioned near most other equipment without concern that the 
neighboring equipment will be influenced by magnetic leakage from the transformer.  It is suggested that the M-8x AR be located either at the top or bottom 
of the rack.  

Start Up:

Upon power up the M-8x AR will perform a series of self-tests that will verify that the input voltage is within normal limits and that the M-8x AR hardware is 
working correctly.  During this period, which can typically take up to 18 seconds, the WITHIN REGULATION LED will flash and power will not be delivered to the 
output receptacles.  If the WITHIN REGULATION LED does not turn green at the end of this start-up period, there is a problem with the input voltage, the load, 
or with the M-8x AR. 
 
Upon completion of the startup tests, the output voltage will be ramped up to the final output value.  During this period, the higher voltage LED indicators will 
activate for a short time.  This does not mean that the input voltage is too high.  After the output voltage settles to its final value, the approximate input voltage 
will be indicated by the LED that is green.  We apologize for the delay in delivering power, but rest assured that your M-8x AR is working very hard to make all 
of the correct decisions when it comes to protecting your connected equipment.

Hardware:

As with any rack mount equipment, be sure to use threaded fasteners that are appropriate for mounting in the rack’s threaded holes.  In particular, the rear 
rack rails attach to the sides of the M-8x AR using 8-32 by 1/4” pan head screws, which is not a metric size.  Other screw sizes may be forced fit into the 
sides of the M-8x AR, but will not provide the same stability and can even strip the threads.  To avoid marring the front panel finish, we recommend using 
plastic washers under the screw heads.

Design

The M-8x AR design is based on an eight-tap Toroidal autotransformer.  The Toroidal design assures minimal leakage of stray magnetic fields, and, because 
of its high efficiency, a very compact size for its rating. The Voltage Regulator’s circuitry monitors the incoming line voltage with each cycle, and compares this 
to a precise voltage reference. If a voltage fluctuation requires that a different tap be selected, the new tap is electronically switched at a precise moment, 
so as to minimize distortion of the AC waveform. If necessary, the M-8x AR can switch taps as often as once each cycle. Most commercial voltage regulators 
using multiple-tapped transformers switch taps at random times, thereby creating voltage spikes and clicks that can leak into the audio!  Hysteresis in the 
tap switching points prevents “chatter” or unnecessary switching back and forth between adjacent taps. Unlike voltage regulators that employ ferro-resonant 
transformers, the M-8x AR is not sensitive to small errors in line frequency, making it ideal for use with generators.
