QUICK START
You gots your good habits, and you gots your bad habits. A good habit is to read at least this much of the manual. A bad
habit is not to read any of this manual. Reading just this section can prevent grief worse than your worst nightmare. Grief
that's hard to get rid of—harder than a bad habit.
Be sure the amplifier is off before making any connections. Euroblocks make connecting and unconnecting the ampli-
fier easy. They are just like little snap-on terminal blocks.The balanced Input blocks are green, and the speaker Output
blocks are black. Driving the MA 6S from a balanced source is recommended. If you just have to drive the MA 6S Input
with an unbalanced source, we recommend using cable that has two conductors with a shield. 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.
Speaker loads should be no less than four ohms per output. If you are running multiple speakers per channel in series or
parallel, check your impedances, and consider the KTM 6 Transformer Kit as an option (see Data Sheet). If you use 100V,
70.7V or 25V output transformers, you need to engage the 80 Hz High-Pass Filter jumpers as described on page Manual-6.
If you are running six separate channels (unbridged), be sure all the BRIDGED switches on the rear panel are de-
pressed. If you are running any channels bridged, you are obviously a power user and we highly recommend you read
further into the manual regarding this issue.
With Input and Output connections completed, be sure all front panel LEVEL controls are all the way counterclock-
wise. Now flip the POWER switch and after hearing the relays click in after a second, notice that the READY lights come
on. Slowly turn up each channel's LEVEL control to the desired gain and if all is well you should hear something pleasant.
If not, re-check connections, put on a better CD, and read more of the manual.
