INSPECTION Your NADY AUDIO SRM-12X/14X 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.] 3. POWER CONNECTION The SRM-12X/14X 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 unit is set to the voltage for your area by referring to the table below: 2. RACK MOUNTING Enclosed in the shipping box you will find a rackmount kit. If you want to make your SRM-12X/14X 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 SRM-12X/14X 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. 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 SRM-12X/14X while the PSU is connected to the AC mains supply. Connect the switched-off SRM-12X/14X and PSU first before you connect the PSU to the mains supply. Lastly switch on the SRM-12X/14X with the power switch on the back panel. Use only the correct NADY power supply unit to connect the SRM-12X/14X to the Mains AC power. 5 CONTROLS AND CONNECTIONS 1. MONO INPUT SECTION (1) MIC INPUT The Mic input is an electronically balanced XLR type (1) designed to accept signals from any balanced low impedance (Low Z) microphone. To accommodate condenser microphones, this input is also (2) equipped with +48VDC phantom power globally switchable to all XLR input jacks with the (3) Phantom Power switch (25) on the back panel. Dynamic or ribbon-type microphones do not require phantom pow(4) ering. It will be necessary to adjust the channel gain with the input Trim control (4) to achieve a nominal operating level. The XLR jack is configured for: Pin1 = ground, Pin2 = positive (+), Pin3 = negative (-). [Note: The Mic inputs are more sensitive than the Line inputs. Also, do not connect mics with the phantom power switched on, as indicated by the Phantom Power On LED (26) in the Master Section of the front panel. Never use unbalanced mic cables with the Phantom Power switched on. Never short the +48VDC to ground, as that can cause serious damage to your mixer. Also, mute the Monitor/PA speakers when turning the phantom power on or off.] (2) LINE INPUT The Line input is designe ...
