INSTALLATION

To ensure years of enjoyment from your NADY AUDIO CMX-16A mixing console, please read and understand this manual
thoroughly before using the unit.

1. INSPECTION

Your NADY AUDIO CMX-16A was carefully packed at the
factory in packaging designed to protect the units in ship­ment. Before installing and using your unit, carefully
examine the packaging and all contents for any signs of
physical damage that may have occurred in transit.

[Please note: Nady Systems is not responsible for ship­ping damage. If your unit is damaged, do not return to
Nady, but notify your dealer and the shipping company (if
shipped to you) immediately to make a claim. Such claims
must be made by the consignee in a timely manner.]

2. RACK MOUNTING

Enclosed in the shipping box you will find a rackmount kit.
If you want to make your CMX-16A a rack mixer, remove
the screws from the side panels and use them to fix the
rack ears (note that there is a left and a right one).

Parts of the mixer and the power supply unit can become
very warm during use. This is normal during operation.
Care should be taken to ensure that there is enough
space around the unit for cooling. Also, do not place the
CMX-16A on high temperature devices such as power
amplifiers etc. or the unit may overheat in operation.

Although the unit's chassis is shielded against radio fre­quency (RF) and electromagnetic interference (EMI),
extremely high fields of RF and EMI should be avoided.

3. POWER CONNECTION

The CMX-16A is designed to operate with the supplied
external power supply unit (PSU). Please make sure that
the power unit supplied is marked for the correct voltage
in your area (120VAC/60 Hz or 230VAC/50Hz). Power
requirements for electrical equipment differ from area to
area. In new installations and portable sound systems, or
any situation in which the AC power is in question, it is
wise to confirm the voltage and use the appropriate
power supply unit before connecting it to power sources.

Check to see that the PSU is set to the voltage for your
area by referring to the table below:

Europe (except UK): 230V, 50Hz

UK and Australia: 240V, 50Hz

USA and Canada: 120V, 60 Hz

For other areas, please check with local authorities.

Do not connect the PSU to the CMX-16A while the PSU
is connected to the AC mains supply. Connect the
switched-off CMX-16A and PSU first before you connect
the PSU to the mains supply. Lastly switch on the CMX­16A with the power switch on the front panel. Use only
the correct NADY power supply unit to connect the CMX­16A to the Mains AC power.
