To ensure years of enjoyment from your NADY AU-
DIO graphic equalizer, please read and understand
this manual thoroughly before using the unit.
These five equalizer models are each designed for
mounting in a standard 19" equipment rack or one of
the many rack type portable cases available on the
market. The units are either single rack (1.75") or
double rack (3.5") as noted. All five models are 8.66
inches deep.
Install the equalizer in a rack with the rack screws
provided. Route the A.C. power cord to a convenient
power outlet away from audio lines. The unit may be
turned on and off from the front panel power switch or
a master equipment power switch. Since the unit
draws a relatively small amount of current during idle,
the unit may be left on continuously. NADY AUDIO
equalizers do not generate an unduly large amount of
heat and do not need to be specially ventilated or
cooled. The units should not be subjected, however,
to high heat environments.
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.
Paralleling inputs and outputs may be accomplished
by using any of the 3 connectors.
Note: The 1/4" TRS are normally used for this
function.

VOLTAGE SELECTOR
Europe (except UK): 230V, 50Hz
UK and Australia: 240V, 50Hz
USA and Canada: 120V, 60 Hz
For other areas, please check with
local authorities.
If the voltage selector is not set for your area:
Confirm that the power cord is not plugged into a wall
outlet. Move the voltage selector switch with a small
screwdriver so that the marker is set to the voltage
for your area.
The 1/4" phone jack, RCA jack, and XLR connector
inputs and outputs can be used for balanced and
unbalanced connections. CAUTION: Using more
than one connector at a time for the INPUT/OUTPUT
pair could unbalance balanced lines, cause phase
cancellation, short a conductor to ground, or cause
damage to the other equipment connected to the
equalizer.
Input/Output Connections
For unbalanced operation,
wire the connectors as follows:
Each of these five NADY AUDIO graphic equalizers is
designed for operation from 120-240 volts, 50-60 Hz
AC supplies. Power requirements for electrical
equipment differ from area to area. In new installa-
tions and portable sound systems, or any situation in
which the AC power is in question, it is wise to
confirm the voltage and select the appropriate line
voltage switch before connecting the instrument to
power sources.
Check to see that the unit is set to the voltage for
your area by referring to the table below:
