ENGLISH
OPERATIONS
During start-up operation, MAS400 LEVEL knob should be at minimum, at “-∞”. Use XLR balanced cables to connect your
balanced sound source outputs, and RCA unbalanced cables to connect your unbalanced source outputs.
Now you can raise the LEVEL knob to desired level. We suggest you to use a spectrum analyzer to monitor the behavior of
your
MAS400 in your current environment and its interaction with other speakers. Checking frequency cancelling problems,
you can use the PHASE switch, then check again with your RTA. If you don’t have such unit, please use songs you know
very well to tune your system.
Please note that moving the LEVEL knob to “0” dB position, the limiter could be activated to prevent way any extreme
level which could damage your
MAS400
speakers.
TIPS
We strongly suggest to avoid exposition to loud music for prolonged periods, you risk to seriously damage your hearing.
In order to avoid
MAS400 overload, please carefully check the overall sound; hearing even a small saturation from your
sound source, please turn counter-clockwise the level knob of the source which is distorting.
Avoid to use extreme EQ settings, which could overload that channel as well your sound system. We suggest you to use
the EQ to emphasize sound nuances and details, even cutting EQ on other channels!
In order to prevent unpleasant and dangerous speakers switch-on thump, please turn the LEVEL knob to “0” after every
session, and check the LEVEL knob “0” position starting any new session.
