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 amplifier
easy. ey are just like little snap-on terminal blocks.e bal-
anced Input blocks are green, and the speaker Output blocks
are black. Driving the MA 6S from a balanced source is recom-
mended. 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.

WEAR PARTS: is product contains no wear parts.
Speaker loads should be no less than 4 Ω 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 depressed. 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 counterclockwise.
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.
