INSPECTION Your NADY AUDIO SD-2418 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.] CONTENTS · Instruction manual · SD-2418 (verify that the unit's serial number is same as shown on shipping carton) · AC Power cord · Warranty Card RACK MOUNTING The SD-2418 fits into one standard 19" rack unit of space (1 3/4"). 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 (at least 12" or 30cm). Do not place the SD-2418 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation. Also, do not place the unit on speakers as this may cause them to move and/or fall due to speaker vibrations. 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. POWER CONNECTION The SDR-260 has an internal power supply and is designed to operate from an external AC source. Power requirements for electrical equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch on the bottom panel is proper for your area (120VAC/60 Hz or 230VAC/50Hz) per the information 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.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 that can damage your speakers or your ears, especially when monitoring with headphones.

POWER SWITCH Use this switch to power unit ON or OFF. The integrated LED will light when the unit is ON. Before turning on this unit, verify connection to the proper voltage AC source, check all connections and turn down the level controls of equipment connected to the outputs. 2. MODE DISPLAY LED The corresponding LED will light green to indicate whether the SD-2418 is set to Single Mode 1-8 (stereo) or Dual Mode 2-4 (stereo). In Single Mode, the signal input into Ch A is distributed to outputs 1 through 8. In Dual Mode, the signal input into Ch A is distributed to outputs 1 through 4 and a signal input into Ch B is distributed to outputs 5 through 8. 3. CHANNEL A SIGNAL LED This LED lights green when an audio signal is detected at the input of Channel A. The LED will light red when the input signal is too high and causes clipping. If the LED is blinking red, turn down the volume level of the audio equipment source. 4. CHANNEL B SIGNAL LED Same operation as Channel A LED 5. LEVEL CHANNELS (1 - 4) Each control adjusts the Output volume of outputs 1-4 from ­ to +6dB. 6. LEVEL CHANNELS (5 - 8) Each control adjusts the Output volume of outputs 5-8 from ­ to +6dB. REAR (6) (4) (3) (2) (5) (4) (3) (7) Bottom Panel (1) 1. FUSE HOLDER & POWER CORD CONNECTOR This fuse holder contains an AC primary fuse. When this fuse blows, replace it with the same type fuse, size and power rating (see SPECIFICATIONS). If it continuously blows, stop replacing the fuse and refer servicing to qualified personnel. The cord connector is used to connect the AC power source to your power amplifier. (CAUTION: After checking the AC supply voltage, be sure that the correct fuse is in the fuse holder.) CAUTION: DO NOT REMOVE THE AC PLUG CENTER GROUNDING PIN. 2. SELECT SWITCH This push button switch selects the mode of operation. When the switch is out, Single Mode 1-8 (mono) is selected. Depressing this button selects Dual Mode 2-4 (stereo). 3. INPUTS Channel A and Channel B XLR balanced line level inputs. 5 4. LINK OUTPUTS Ch. A and Ch. B XLR outputs linked in parallel with the respective input. 5. OUTPUT CONNECTORS (1 - 4) Balanced XLR outputs for Ch. A signal. 6. OUTPUT CONNECTORS (5 - 8) Balanced XLR outputs for Ch. A signal, when in Single Mode, and Ch. B signal when in Dual Mode. Note: All output signals are in-phase with the input signal. 7. INPUT VOLTAGE SELECT SWITCH (BOTTOM PANEL) Select 115V/60Hz or 230V/50Hz as appropriate for your area. (CAUTION: Selecting the wrong voltage can damage your unit.
