BEFORE YOU BEGIN, INSPECT UPON RECEIPT
The Furman M-8x AR Voltage Regulator is intended to protect sensitive electronic equipment from problems caused by AC line voltage irregularities such
as brownouts, sags, and over-voltage conditions. Such irregularities can cause audio tonal changes, digital equipment malfunctions (such as loss of MIDI
programs or other data), or in extreme cases, permanent damage. The M-8x AR can accept input voltages over a wide range (see tables below) and convert
this to a steady, stable /- 5V output.
AC LINE VOLTAGE REGULATOR
The M-8x AR has eight receptacles on the rear panel, and one on the front panel, all are functionally in-
terchangeable. The receptacles are regulated, spike-suppressed, and filtered against RFI with a 3-pole
filter, making the M-8X AR a full-function power conditioner. The M-8x AR has no external controls
other than an on-off switch.
Note: The M-8x AR is designed for use with AC voltage only and DC voltages should never be applied.
Also, the M-8x AR does not change or regulate the line frequency in any way. The output frequency will
always be the same as the incoming line frequency.
Maximum and Minimum Load:
The M-8x AR can handle loads totaling up to 15 amperes as long as the input voltage is greater than or
equal to 124 Volts. For voltages below 124 Volts, the nominal 15 Amp current handling capacity must
be de-rated at approximately 113 milliamps per volt below 124 VAC.
To successfully handle worst-case brownout conditions, you should plan your total load so that it does
not exceed 12 amps, or 1400 watts under brownout conditions. Please note that the total load refers
to the combined current demand of all devices plugged into the M-8x AR, not just each individual
receptacle, or load.
