QUICK START
Sure, you say, “it’s just a three channel amp, I'm in a hurry
and I don't need to read the manual.” But at least read this little
section so you really know what to expect, and your installation
can go even faster.
Be sure the Amplifier is off before making any connections.
Euroblocks make Amplifier connection easy. They are just like
“snap on” terminal blocks. The balanced Input blocks are three-
terminal female connectors. The Output blocks are two-terminal
female connectors.
Driving the MA 3 from a balanced source is recommended.
If you must drive the MA 3 Input with an unbalanced source,
we recommend using a cable that has two conductors plus a
shield, and be sure to keep cable lengths as short as possible (un-
der 10 feet). See the RaneNote, “Sound System Interconnection”
(contained in this booklet).
Nominal speaker loads should be no lower than 4 Ω per

Output. If you are running series or parallel combinations, be
sure and check your total load impedance. For constant-voltage
distribution, consider using the optional TF 407 (40 W / 70.7
V) or TF 410 (40 W / 100 V) transformer. Transformers may
be installed inside the MA 3 on any number of output channels
required. If you intend to use constant-voltage distribution trans-
formers, you may want to read the RaneNote “Constant-Voltage
Audio Distribution Systems” (contained in this booklet).
Once Input and Output connections are completed, be sure
all rear panel LEVEL controls are all the way counterclockwise.
Now flip the POWER switch on. After a couple of seconds,
slowly turn up each channels’ LEVEL control to the desired
gain. Maximum yields the most effective dynamic range control
for the built-in Limiter). If all is well, you will hear something
pleasant. If not, re-check connections, put on a better CD, and
read more of the manual.
