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: • PA-4180 Mixer Section • PA-4180 Left Speaker • PA-4180 Right Speaker • (2x) 20' Speaker Cables • AC cord • Instruction Manual • Warranty Card 2. SETUP After transporting the PA-4180 to the desired location, stand the unit up on its feet and wheels. Unclasp and unhook the side panel latches and carefully remove the top speaker by lifting on the latch panel of the speaker and pulling apart the hinge connection. Lift off the mixer section in the same manner. Position the PA-4180 mixer section on a flat surface with the control panel facing front. 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 Mixer Section for cooling. Make sure the side panel vents are not obscured and have plenty of ventilation. Also, do not place the PA-4180 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation. Although the PA-4180 is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF and EMI should be avoided. 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. Connect the speaker cables to the input jacks on the rear panel of both the Left and Right speakers. The connecting terminal offers Speakon™ and two 1/4" jacks for easy daisy chaining. Connect the other end of each cable to the corresponding Left and Right speaker outputs on the rear panel of the PA-4180 mixer section. Position the length of the cables so they will not be a safety hazard to people. Connect all sound sources to the appropriate inputs i.e., microphones, keyboards, CD players, karaoke machines. 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. Before turning on, connect up the speakers and all inputs and outputs desired and turn down the Master Volume. 4 FRONT PANEL CONTROLS & CONNECTIONS FRONT PANEL CONTROLS & CONNECTIONS FRONT PANEL Note: 1 through 9 below are (1) referenced to Channel 1. The other 3 Channels are identical. (2) (1) GAIN CONTROL The channel gain controls determine the signal level input to each channel. (3) (2) HIGH EQ Turn this control to the right to boost high frequencies on (4) the channel, adding crispness to percussion from drum machines, cymbals and synths. Turn to the left to (5) cut these frequencies, reducing sibilance, hiss, or high frequency feedback. The control has a shelving (6) response giving 15dB of boost or cut at 12kHz. (3) MID EQ (7) Turn this control to the right to define the midrange or bring out the vocals on the channel. Turn to the left to cut these frequencies and reduce midrange muddiness. The control has a shelving response giving 15dB of boost or cut at 2.5kHz. (8) (4) LOW EQ Add warmth to vocals or extra punch to guitars, drums and synths on the channel by turning this control to the right. Turn to the left to reduce stage rumble, hum or to improve a mushy sound. The control has a shelving response giving 15dB of boost or cut at 90Hz. (9) (6) PAN CONTROL The channel Pan positions the output of the channel in the stereo field of the main mix. Its constant-power design ensures there are no level discrepancies whether a signal is hard-panned, center-stage, or somewhere in-between. (7) LEVEL CONTROL The Level Control determines the amount of the channel signal sent to the main mix and Tape Output. (8) LINE INPUT The Line input is designed to accept balanced or unbalanced line-level signals such as those from keyboards, drum machines, or samplers. Use the GAIN control (1) to adjust for the desired level. If a balanced signal is to be connected to the line input, then a 1/4" TRS (stereo) phone plug should be wired for: Tip = positive (+), Ring = negative (-), Sleeve = ground. (9) MIC INPUT The Mic input is an electronically balanced XLR type designed to accept signals from any balanced low impedance (Low Z) microphone. It will be necessary to adjust the channel gain with the input GAIN control (1) to achieve a nominal operating level. The XLR jack is configured for: Pin1 = ground, Pin2 = positive (+), Pin3 = negative (-). (Note: Only either the M...
