To ensure years of enjoyment from your NADY AUDIO graphic
equalizer, please read and understand this manual thoroughly
before using the unit.
The GEQ-215 is designed for mounting in a standard 19” equip-
ment rack or one of the many rack type portable cases available
on the market. The unit is 1u single rack (1.75”) and 5 inches
deep.
Install the equalizer in a rack with rack screws (not included).
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. The equalizer does not generate
an unduly large amount of heat and does not need to be specially
ventilated or cooled. It should not be subjected, however, to high
heat environments.
Although the unit is shielded against radio frequency (RF) and
electromagnetic interference (EMI), extremely high elds of RF
and EMI should be avoided.
INPUT/OUTPUT CONNECTIONS
The 1/4” phone 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 equip-
ment connected to the equalizer.
For balanced connection,
wire the connectors as follows:
For unbalanced operation,
wire the connectors as follows:
POWER CONNECTION
The GEQ-215 is designed for operation with 105-130 volts AC
at 60Hz or 210-240 volts AC at 50Hz power sources . 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 conrm 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:
Europe (except UK): 230V, 50Hz
UK and Australia: 240V, 50Hz
USA and Canada: 115V, 60 Hz
For other areas, please check with local authorities.
If the voltage selector is not set for your area:
Conrm 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.
