INSTALLATION

To ensure years of enjoyment from your NADY AUDIO MXE-812 mixing console, please read and understand this manual thoroughly
before using the unit.

1. INSPECTION

Your NADY AUDIO MXE-812 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

The MXE-812 can be rackmounted with the optional RMK-812 rackmount kit which can be ordered from your dealer or through the
Nady Service Department (see back page).

3. SETUP AND OPERATION

Parts of the 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 MXE-812 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.

The MXE-812 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/50 Hz). 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.

Europe (except UK): 230V , 50Hz

UK and Australia: 240V, 50Hz

USA and Canada: 120V, 60 Hz

For other areas, please check with local authorities.

When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to the AC power
source to avoid possible loud transients which can damage your speakers or your ears, especially when monitoring with headphones.
Set the noted controls to the positions indicated below to further minimize the chance of undesired noise when first powering up your
MXE-812 :

GAIN FADERS (8/33) .................................................................................................................................................... SET TO MINIMUM

HI, MID & LOW EQ’S (4) AND PAN/BALANCE CONTROLS (6/14) ............................ TURNED TO THE CENTER DETENT POSITION

AUX/EFF CONTROLS & PHONES LEVEL CONTROLS (5/20)................................. TURNED COMPLETELY COUNTERCLOCKWISE

ALL OTHER CONTROLS SHOULD ALSO BE TURNED COMPLETELY COUNTERCLOCKWISE

Power up the unit as noted in Power Connections, Indicators, and Switches (Section 3e in CONTROLS AND CONNECTIONS,
page 11).
