OPERATORS MANUAL MA 3
MULTICHANNEL AMPLIFIER
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 (under 10 feet). See Rane Note 110, “Sound System Interconnection” (contained in this booklet).
Nominal speaker loads should be no lower than 4 ohms 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 transformers, you may want to read RaneNote 136
“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 counterclock-
wise. 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.
