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 SpeakonTM 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. 1. INSPECTION Your NADY AUDIO Ensemble PA-4180 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.

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 4 FRONT PANEL CONTROLS & CONNECTIONS FRONT PANEL (1) Note: 1 through 9 below are referenced to Channel 1. The other 3 Channels are identical. (1) GAIN CONTROL The channel gain controls determine the signal level input to each channel. (2) HIGH EQ Turn this control to the right to boost high frequencies on the channel, adding crispness to percussion from drum machines, cymbals and synths. Turn to the left to cut these frequencies, reducing sibilance, hiss, or high frequency feedback. The control has a shelving response giving 15dB of boost or cut at 12kHz. (3) MID EQ 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. (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. (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 Mic or the Line input of a given channel can be connected at one time. Do not connect both simultaneously to the same channel.) (2) (3) (4) (5) (6) (7) (10) (8) (11) (10) POWER "ON" LED The POWER LED will light red when you turn on the power switch ON. (11) AMPLIFIER CLIPPING LED This LED turns red when the output signal is clipping. It is acceptable if the red LED lights very occasionally. If the red LED lights more than occasionally, you should turn down the volume to avoid audible distortion and damage to the speakers. Note: Speakers damaged due to hard clipping are not covered under warranty. 5 (9) (5) EFFECTS CONTROL The EFF control adjusts the signal level sent by each channel to the internal DSP (Digital Sound Processor) and also to the EFFECT LOOP SEND output (20). FRONT PANEL CONTROLS & CONNECTIONS (12) (16) (20) (22) (13) (17) (21) (14) (18) (15) (19) (20) EFFECT LOOP SEND This line level output can be connected to external recorders, amplifiers, or effects processors. The signal is a mix of the channel inputs determined by each Channel EFF SEND control. (21) EFFECT LOOP RETURN This input can be used to return the effected signal into the PA-4180 or it can be used as a auxiliary input. The input signal can be adjusted by the Master Volume and the unit the return jack is connected to. (22) TAPE IN AND TAPE OUT The Left and Right TAPE IN allows cassette recorders or CD players to be added to the Main output. The RECORD OUTPUT, with TAPE RCA jacks, provides signal output to a cassette deck or home audio equipment. (12) MASTER - HIGH CONTROL The control has a shelving response giving 15dB of boost or cut at 12KHz. (13) MASTER - MID CONTROL The control has a shelving response giving 15dB of boost or cut at 2.5KHz. (14) MASTER - LOW CONTROL The control has a shelving response giving 15dB of boost or cut at 90Hz. (15) MASTER - LEVEL CONTROL This adjusts the final level of the Master bus which is output to the speakers. (16) EFFECT - TIME CONTROL This adjusts the delay time between the original audio signal, the first reverb reflection sound and each subsequent reflection. The max time delay is 0.2s (17) EFFECT - DEPTH CONTROL This controls the amount of feedback of the reverb reflection, i.e. the number of reflections and the length of time before they diminish in volume. (18) EFFECT - VOL CONTROL This adjusts the level of the reverb effect sent to the main mix. (19) TAPE CONTROL This control adjusts the level of the Tape Input signal sent to the Master outputs. (23) (23) STORAGE COMPARTMENT The panel can be removed using by pulling on the black canvas strap to reveal this compartment for storing microphones, speaker cables, or installing wireless microphone receivers. 6 REAR PANEL CONTROLS & CONNECTIONS REAR PANEL (24) (24) POWER SWITCH Turns the unit ON or OFF. Always turn level controls down before turning on the unit. (25) VOLTAGE SELECTOR SWITCH For selecting the proper voltage (115/ 230VAC) to match the power supply in your area. Note: To avoid damage to your unit, always make sure this switch is set to the correct supply voltage. Damage caused by improper use is not covered by the warranty. (26) POWER CONNECTOR WITH FUSE HOLDER This standard IEC power cord receptacle is used to connect the AC power to your unit. It features a built-in fuse holder for a 5X20mm, (4A/250V for 115VAC, and 2A/250V for 230VAC operation) fast-blow fuse. If the fuse continuously blows, shut off the unit and have it serviced by qualified service personnel. (27) SPEAKER OUTPUTS Two 1/4" (6.3mm) jacks, each powered by its own separate amplifier output stage, for connecting left and right speaker cabinets. The connected speaker impedance must be 4 ohms or greater. The PA-4180 delivers 90W RMS of power @ 4 Ohms per each speaker output. CAUTION: Do not overload the ENSEMBLE PA 4180 with speaker loads less than 4 ohms as this will degrade performance and may harm the unit. Damage caused by improper use is not covered by the warranty.
