Rane MA 3 Operator's Manual

QUICK START

Sure, you say, "it's just a three channel amp, I'm in a hurry —
I don't need to read the manual." But at least read this little sec-
tion 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 that take up to 12 guage wire.
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 (under 10
feet [3 meters]). See the RaneNote, "Sound System Interconnec-
tion" (contained in this booklet).
Nominal speaker loads should be no lower than 4Ω per out-
put. 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 410 or TF 407 transformers with the MT 6 rack panel.
Transformers may be used on any number of output channels
required, and one MT 6 can be used with two MA 3s. If you in-
tend to use constant-voltage distribution transformers, you may
want to read the RaneNote "Constant-Voltage Audio Distribu-
tion 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 this manual.
