ESI nEar04
1. Introduction
Congratulations on your purchase of the ESI nEar04.
The nEar04 desktop near field monitors have been developed especially for high level home studios
and special project studios. nEar04 have been designed to overcome all the typical limitations of
conventional small sized monitoring speakers providing a special 4" polypropylene curved woofer
cone and a 1" natural silk dome tweeter. Despite the small size, nEar04 still provide reference level
sound quality and enough power for audio monitoring in a digital audio production environment.
2. Basics & Installation
For optimal performance of nEar04, read the instructions in this manual thoroughly and carefully
before you are using the speakers.
Unpacking / Handling
To remove the monitors from the carton its best to turn the package carefully upside down on the
floor or on a table and then lift the carton vertically up slowly to leave the monitors resting in the
packaging foam. Make sure that you don’t grab the speaker driver units on the front to avoid
damage. Now check the monitors for signs of damage that might have occurred in shipping. In the
unlikely event of this, please contact the reseller of the product immediately. Be careful when you
remove the packaging foam. Please keep all packing materials.
Connection
High quality balanced or unbalanced audio cables are
recommended for input connection. The monitors typically
connect to the line level output of a mixing console or to a
computer audio card. One monitor has to be connected to
power connection, the other monitor is connected via the
supplied speaker wire to the first monitor. Make sure the
power of the main monitor is switched off before you connect
any audio cables. Also turn down the volume initially.
TRS balanced / unbalanced connection
Connect male side of TRS balanced or unbalanced cable to
the TRS input of nEar04 – as show on the picture above (the
picture shows the left audio channel connection only). Do
this for both the left and right audio channels with separate
cables. Make sure the power cable is connected as well.
Second speaker connection
After that, connect the second speaker with the included speaker wire. Make sure the + / - (red /
black) connectors are not swapped with each other to avoid phase problems during playback. The
complete setup will then look like shown on the following picture:

3. Placement of the speakers
The placement of monitoring speakers is very critical and can compromise their performance. This
is a general rule for every loudspeaker. To monitor with nEar04 utilizing their maximum
capabilities, an appropriate listening environment and a correct placement are important.
Positioning
In principle, two units and the listener should be positioned or aligned in a regular triangle form.
Please refer to the following diagram to understand how to position your monitors.
The height of the units, more precisely the top of the woofer, is recommended to be at the ear level
of the listener. Keep in mind that in a typical monitoring environment, you are sitting in front of
your workstation. Refer to the following diagram:

Orientation
It’s very important to place the nEar04 vertically. Never place them horizontally.
Comments
Please also make sure to not place any obstacles that may block the flow of air or that could
generate sound reflections (especially highly reflective material including glass or metal) in front of
the speakers. Also, don’t put plants in pots on top or too close to your monitoring speakers.

1. TRS input – these jacks accept TRS input connections, either balanced or unbalanced. For
balanced connections, a 3-conductor TRS plug is necessary. The TRS input is wired like this:
INPUT SIGNAL TRS CONNECTIONS
+ Tip
- Ring
Shield Sleeve
Unbalanced wiring works with either a 2- or 3-conductor TRS connector. A 2-conductor TRS plug
(or sometimes also just called TS plug) automatically grounds the minus signal input, whereas a 3-
conductor TRS plug wired unbalanced provides the option of leaving the minus open or grounded.
We recommend that you ground the unused input.
2. vent port –nEar04 is a vented box speaker system with a vent port on the rear panel. Make sure
you are not blocking the vent port (i.e. by putting the speaker too close to a wall) or the sound
colour will be changed.
3. speaker wire connection – use these connectors to connect the included speaker wire with the
second passive nEar04 speaker.
4. power switch – when you push the power switch, nEar04 will be turned on, and
–surprise– it will be turned off when you push the power switch again.

5. power port with ext. fuse – use this connector to plug in the detachable 3-circuit line cord that
connects to the power outlet.
6. AC selection – you can select either 110V or 230V AC power according to your local
requirements. Make sure this is selected properly before you switch on nEar04 for the first time or
your equipment could be damaged.
Front Panel / Side View
volume control knob – use the volume control to set the proper output level of nEar04. Please be
careful and never set the volume too high as it could damage your equipment otherwise.
power indicator – the LED on the front shows if nEar04 is switched on or not.
Notice: The above picture shows the front panel of the left speaker. The right speaker does not have
a volume control know and power indicator LED.
