REAR PANEL DESCRIPTION
 INPUTS: ese are balanced Euroblock connectors. Cable should include two wires with shield. Euroblocks accept up to 12
AWG wire. e shield may be attached to either chassis or signal ground. For unbalanced sources consult the included RaneNote,
“Sound System Interconnection.”
 OUTPUTS: Connect the speaker(s) to each of the six channels by means of the Euroblock connectors with 18 to 12 AWG wire
(See  for Bridged operation).
 NORMAL/BRIDGED switch: With the switch in the out position and the red BRIDGED indicator on, the MA 6S is operating
in BRIDGED mode. e MA 6S utilizes the BRIDGE switch to make internal connections between each pair of channels: 1&2,
3&4, and 5&6. Whenever a signal is connected to an odd numbered channel (say channel 1), the next even-numbered channel is
driven inverted when the BRIDGE switch is activated. Connect Inputs to odd amplifier channels only (1,3,5), and connect speak-
ers to the “+” terminals of each channel pair as shown in gray on the chassis silk-screen. When the BRIDGE switch is inactive, the
internal connection is defeated and both channels operate independently.
 AC line cord: Plug this into a grounded l20 VAC AC outlet (or 230 VAC if the MA 6S is internally wired for 230 V operation).
 Line FUSE: For 120 volt operation, use only a 15 amp 250 volt Fast-blow (or Normal blow—not Slow blow) fuse, 1.25" long, such
as Buss ABC-15 or equivalent. For 230 volt operation use Buss AGC-8 or equivalent.
 Fan filter: is washable filter may easily be removed for periodic cleaning by gently pulling on the black plastic housing and then
lifting it away–perform this feat with the fan off, of course. Once the filter is removed, rinse it under hot tap water; use dish soap
to cut through particularly stubborn “tav sludge.” e MA 6S draws a tremendous amount of air to ensure proper cooling and
resultant long term reliability. Check and clean the filter as often as necessary, especially if the THERMAL overload indicator ever
comes on.
IMPORTANT: Keep this filter clean to ensure proper cooling and reliability. Never remove the filter with the unit plugged in.
