User manual RANE MA 6S

[. . . ] Connect the sources positive or "hot" to the MA 6S's +, the negative or ground to the MA 6S's ­, and connect the shield to the MA 6S's SHIELD (center of Euroblock connector). Do not connect the shield at the source end. Keep your input cable lengths as short as possible. See the RaneNote, "Sound System Interconnection" for more information regarding this issue.

Cable should include two wires with shield. The 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. The 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 speakers 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: This washable filter may easily be removed for periodic cleaning by gently pulling on the black plastic housing and then lifting it away­perform 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. " The 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.

[. . . ] The MA 6S is shipped with these jumpers in the out position (filters defeated). Moving this jumper to the in position activates the filter. CAUTION: WAIT ABOUT 15 MINUTES AFTER THE AMPLIFIER HAS BEEN POWERED DOWN BEFORE BEGINNING DISASSEMBLY, TO ALLOW THE POWER SUPPLY CAPACITORS TO DISCHARGE. Remove the bottom cover: 4 each #6 x 3/8" phillips screws on the bottom of the side rails and 12 each #6 x 1/4" phillips screws on the bottom cover. [. . . ]
