too high number of bands might conduct to trespassing excessively the limit of a single
band.

Auto Bands calibration. If activated, every time the unit is turned ON or a session is
started, the limiter generates pink noise along 10s for bands level comparison with the
levels stored in memory when the first calibration was executed and checks the system´s
efficiency.

External Alarm - With the combined action of several pins at the DB9 AUX connector, we
can reduce or raise the sound level immediately in the quantity consigned in the Immediate
attenuation box, plus a slow decay of the quantity consigned in the Second attenuation
box with a ramp of 1dB/second.

Message priority - Is the external alarm referred to in previous chapters. Called “Fire
Alarm” as its main function is to connect the local fire alarm system to EQ Limit in order to
mute de music sound and activate a gentle fire alarm message through the main PA
system in case of fire. To activate this function, turn the
Message Priority button ON .

Change Password – An attempt to change any configuration parameters in the limiter will
lead the SCL application to ask for the limiter password before changes are made. The
default password is 1234. To avoid unauthorised access to the limiter we recommend
changing the default password. The password can be alphanumeric of up to 10 characters.
Type in the new password in the
New password box and click the OK button. The limiter
will ask for the old password before permitting a password change.
Once the correct password is given, the EQlimit limiter will not ask for it again unless a 5
minute elapse time occurs between two successive parameter changes.

Master Password – If you forget your password, MRC Audio can provide a master
password, active only for that single unit, as a function of the limiter serial number, and is
active only once.
For MRC Audio to be able to provide a master password, you must provide MRC Audio
the serial number of the unit and the number that appears in the
CMs box.
Introducing a master password is registered in the limiter’s non volatile memory as an
event, together with the date and time as all other events, and together with the authorised
user that has entered the master password.
NOTICE: Each MRC Audio EQlimit has up to ten master passwords. Each time one is used it will not work
ever again. If all ten master passwords are used and still the user keeps on forgetting the password, the
limiter will have to be serviced at MRC Audio to restore ten new master passwords.

Internet : The EQlimit limiter can access Internet via two ways: the first is to use local
Ethernet TCP/IP net with access to Internet (ADSL) and the second is through a GPRS
modem with its corresponding digital data available SIM card.
There is an optional RJ-45 connector located at the backplane, for connection to the local
area net, and a DB-9 connector to connect to a GPRS modem. EQlimit connects to Internet
automatically, the user must only activate this communication by turning the
INTERNET
button to its ON position.
For the correct use of the AUX connector connections, please contact MRC Audio
to provide a schematic and detailed instructions for use.
