INSTALLATION

To ensure years of enjoyment from your NADY AUDIO

Ensemble PA-4180, please read and understand this

manual thoroughly before using the unit.

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. 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.

FRONT PANEL CONTROLS & CONNECTIONS

FRONT PANEL

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.

(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).

(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.)

(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.

FRONT PANEL CONTROLS & CONNECTIONS

(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.

(22)

(20)

(21)

(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.
