•Use only attachments / accessories specified by the manufacturer.
•Always shut down power supply when not in use to save energy and for prolonged lifespan.
•Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary
considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if
exposed to sufficiently intense noise for a period of time. The U.S. Government’s Occupational Safety
and Health Administration (OSHA) has specified the permissible noise level exposures shown in the
following chart. According to OSHA, any exposure in excess of these permissible limits could result in
some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is
recommended that all persons exposed to equipment capable of producing high sound pressure levels
use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or
over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if
exposure is in excess of the limits set forth here:

INTRODUCTION
INTRODUCTION
The GECKO® ESTINY EQ 7043 graphic equalizer is a very useful audio signal processing tool in situation
where precise frequency control is required across the audible frequency spectrum (i.e. music masterings).
The GECKO® ESTINY EQ 7043 graphic equalizer can be used in tuning any acoustical environment (i.e.
home theater rooms, recording and mastering studios, concert halls), to stop ringing, increase clarity, and
flatten the overall frequency response of the environment.

CONTROL ELEMENTS
CONTROL ELEMENTS
FRONT PANEL
1. INPUT GAIN CONTROL
This control sets the signal level to the equalizer. It is capable of -12dB to +12dB of gain. Its effect is
apparent by viewing the OUTPUT LEVEL METER.
2. EQ BYPASS SWITCH
This switch removes the graphic equalizer section from the signal path. The BYPASS switch does not,
however, affect the INPUT GAIN, or LOW CUT filters.
3. EQ BYPASS LED
This red LE lights when the EQ is in BYPASS mode. Note that BYPASS mode only affects the graphic
equalizer section. The INPUT GAIN and LOW CUT controls remain unaffected when the EQ is bypassed.
4. BOOST (+) / CUT (-) RANGE SELECTION SWITCH AND LED
This RANGE switch selects which of the two BOOST (+) / CUT (-) range the equalizer will use, either 6dB or
15dB. The red LE lights up when the 15dB range is selected, and the amber LE lights up when the 6dB
range is selected.
NOTES: The BOOST (+) / CUT (-) switch is slightly recessed. This is to prevent
accidental activation of the switch, possibly causing damage to other sound system
components.
5. OUTPUT LEVEL LED METER
These four LE s indicate output level of the equalizer. The red LE is 3dB below clipping and is marked as
+18dBu. It monitors the level at the OUTPUT of the equalizer after all other processing.
6. CLIP LED
This LE lights whenever any internal signal level reaches 3dB clipping, which may occur when any of the
followings happen: (1) the input signal is “hotter” than +22dBu; (2) excessive gain is applied by the INPUT
GAIN control; or (3) excessive boost is applied using the FREQUENCY BAN SLI ERS.

7. FREQUENCY BAND SLIDERS
Each one of this slider potentiometer will boost or cut at its noted frequency by 6dB or 15dB, depending upon
the RANGE switch. When all the sliders are in the center demented position, the OUTPUT of the equalizer is
linear (flat). The frequency band centers of the GECKO® ESTINY EQ 7043 are marked at ⅓ or ⅔ of an
octave interval on ISO standard spacing.
8. LOW CUT SWITCH
The LOW CUT switch inserts or removes the 18dB/Octave 40Hz Bessel low-cut filter from the signal path.
When the LOW CUT switch is pressed in, the 18dB/Octave 40Hz Bessel low-cut filter is in the audio path.
REAR PANEL
9. POWER SWITCH
Switch the power ON [I] and OFF [O]. Always make audio connections with the power switch in the OFF
position.
10. IEC - AC POWER CORD RECEPTACLE
Plug the AC power cord (supplied) into the GECKO® ESTINY EQ 7043. Plug the other end into a standard
wall power outlet. Take care to route power cables away from audio lines.
WARNING: Be sure to verify your actual line voltage is the same as the voltage level
printed below the AC power receptacle. Connection to an inappropriate power
source may result in extensive damage which is not covered by the warranty.
11. INPUTS
Three types of input connectors are provided for INPUT connections: female locking XLR type connectors,
¼” TRS connectors, and a barrier terminal strip. The maximum input level that the equalizer can accept is
+22dBu (ref: 0.775 Vrms).

12. OUTPUTS
Three types of output connectors are provided for OUTPUT connections: male XLR type connectors, ¼” TRS
connectors, and a barrier terminal strip.
13. CHASSIS GROUND LIFT
By removing the jumper connecting the two screws on the barrier terminal strip, the chassis ground is
separated from the circuit ground of the equalizer unit. This is sometimes necessary to prevent ”ground
loops” in a sound system. When lifting the ground strap, you must make a connection from the circuit ground
terminal to some other ground point in your audio system in order for the equalizer to function properly.
Wiring connectors with ground.
MAKING CONNECTIONS
MAKING CONNECTIONS
The GECKO® ESTINY EQ 7043 graphic equalizer has balanced INPUTS and OUTPUTS that can be used
with any balanced or unbalanced line-level device. For more specific information about cabling possibilities,
please refer to INSTALLATION CONSI ERATIONS.
To connect the equalizer to your sound system, refer to the following steps:
1. Turn OFF all equipment before making any connections.
2. Mount the GECKO® ESTINY EQ 7043 on a 3U rack space (not included). It can be mounted
above or below anything that does not generate excessive heat. Although it requires no special
ventilation, ambient temperatures should not exceed 113°F (45°C) when equipment is powered.
3. Make connections using quality audio cables (i.e. GECKO® TRUTH T3AL) and connectors (i.e.
GECKO® OLYMPIAN connectors) according to your requirements. Audio connections are made via
XLR (male and female) and ¼” TRS connectors, or barrier terminal strips. All of these connectors for
the INPUTS and OUTPUTS can be used for balanced or unbalanced connections.

NOTES: The use of more than one connector at a time for the INPUTS could
unbalance balanced lines, cause phase cancellation, short a conductor to ground, or
cause damage to other equipment connected to the equalizer. More than one
OUTPUT may be used simultaneously as long as the combined parallel load is not
greater than 600Ω.
4. Select the operating range with the BOOST (+) / CUT (-) RANGE selection switch. Be sure to reduce
audio levels at the power amplifiers when changing the setting of this switch as it may generate an
audible transient.
5. Connect the AC power cord (supplied) to the unit’s rear panel POWER receptacle and to an
appropriate AC power source. Route the AC power cord away from audio lines. The unit may be
turned ON and OFF using the rear panel POWER switch or a master equipment power switch (i.e.
GECKO® GALILEE series power sequencers).
INSTALLATION CONSIDERATIONS
INSTALLATION CONSIDERATIONS
HOOKUPS AND CABLING
The GECKO® ESTINY EQ 7043 graphic equalizer is designed for nominal +4dBu levels. The equalizer can
be used with either balanced or unbalanced sources, and the OUTPUTS can be used with either balanced or
unbalanced loads, provided proper cabling is used.
A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the same
signal but in opposite polarity when referenced to ground (cable shield at ground potential). An unbalanced
line is generally a single-conductor shielded cable with the center conductor carrying the signal and the
shield at ground potential.
INPUT CABLE CONFIGURATIONS
The GECKO® ESTINY EQ 7043 graphic equalizer has an input impedance of 40kΩ balanced and 20kΩ
unbalanced. This makes the GECKO® ESTINY EQ 7043’s audio INPUTS suitable for use with virtually any
low source impedance (under 20kΩ).
OUTPUT CABLE CONFIGURATIONS
The GECKO® ESTINY EQ 7043 graphic equalizer’s output is capable of driving a 600Ω load to +18dBu.
For maximum hum rejection with a balanced source, avoid common grounding at the equalizer’s INPUTS
and OUTPUTS.
