INTRODUCTION
The iO-48 is a very powerful high-end audio processor, ideally suited for install applications, where it
combines the functions of a multitude of conventional products in a compact 1U unit with extensive
remote control capabilities over ethernet.
It is important to remark that there are not any front/rear panel controls in the unit. It MUST be controlled
using the 11-NET software always.
To achieve the best flexibility and audio performance, the iO-48 units have four analog audio inputs and
eight analog audio outputs which can be configured in a selection of basic crossover modes – 2 x 4 way; 4 x
2 way; 2 x 3 way + 2 Aux and 1 x 8 way (as applicable to i/o configurations). It also offers a “free assign; matrix”
mode which allows completely flexible routing and gain adjustments of any input routed to any output.
Flexible channel linking enables quick and easy configuration of common crossover setups or customized
configurations as required.
Compressors are available on every input as well as a high pass filter, 8 bands of parametric EQ, 3 bands of
dynamic EQ, a 28-band graphic EQ, and up to 1.3 seconds of delay.
Every output channel has high and low pass filters, 16 bands of parametric EQ, up to 1.3 seconds of delay as
well as a new limiter designed to offer the best driver protection with the lowest distortion.
The iO-48 runs at a fixed sampling rate of 96kHz.
The Ethernet based computer control software gives you the ability to not only control all the devices on a
network but also to store preset memories and configure systems offline.

E11EVEN-NET CONTROL SOFTWARE
E11EVEN-NET is an Ethernet based computer control platform that gives the end user the ability to not
only control all the devices on a network, but also to store presets and configure systems offline.
Compatibility with Microsoft Windows, Apple Mac and Apple iPad too, you can control your system the
way that suits you. USB connection (Microsoft Windows only) is also available on some devices, allowing
quick connection to a single device.
E11EVEN-NET is free for all E11EVEN Sound iO-48 user´s. It can be downloaded from the
www.e11evensound.com web page.
The unit can be connected to the PC using an ethernet switch/router and the adequate ethernet cabling,
or just using a standard USB cable.
If the router used is Wireless, the unit can be controlled via Wifi.

10 E11EVEN SOUND \ IO-48 \ User’s Manual
When using the iO-48 there are two basic procedures:
1. Recalling a preset from the bank of memories included in the iO-48 units (also recalling an
output channel preset). Each iO-48 unit comes with a bank of memories that includes different E11EVEN
Sound systems and combinations of them.
2. Creating a custom preset from an existing one; from the default settings or by recalling presets
per output. The iO-48 units also have the possibility of recalling a preset per each output.
These are called Output Channel Settings.
Follow this process to reach the option you desire:

“add/delete” devices
“racks” or “zones” where to add devices
The user or application preferences are accessible in the icon:
very useful option when
working always in the
same installation
When Going Online the software
will:
- Get parameters from units
- Send parameters to untis
- Ask
Recommendation: ASK
Between all these preferences the most important ones are the “Load last file on startup” which is very
useful when connecting the PC always to the same network of processors or installation, and the
selection “When going online”.
There are 3 different options, “Get parameters form the units”, will bring to the PC the existing settings in
the “devices”.
“Send parameters to the units” will do the opposite, it will “erase” all the settings in the device and
substitute them by the ones existing in the computer. This option is very useful when working “offline”
setting all the parameters first, and later “sending” them to all of the units for the first time, for instance.
We always recommend to use ASK all the times.
When physically
connected to a network
of “devices” the user
can directly Go “online”
and the software will
find all the units
Creating a new preset “offline”
D-Net allows the user to work “online” or “offline” with the devices. Working “offline” allows to create
presets with filters, limiters, EQs etc. and later on when going “online” sending them to the unit(s).
Here it is shown the main window of the software. The “devices” can be distributed in “racks” or
“zones” in the left area of the screen. To “add” or “delete” a “device” just use these options:
11
E11EVEN SOUND \ IO-48 \ User’s Manual

When working “offline” The user can “add” devices following this process: press +
and select the iO-48 processor
If there are no “racks” created, by default the “added” units are all included in the “Main rack”:

respect to the limiter threshold) and Routing Wizard.

Next step will be defining the “routing” of the system. Click on the “Routing Wizard” and make your
choice. In this case we are going to select a 2 x 4 way Crossover.

14 E11EVEN SOUND \ IO-48 \ User’s Manual

Keep in mind that when a standard 2x4 or 2x3 or 4x2 crossover is set up, the channels are automatically
linked.
For instance, in a 2x4 configuration, channels 1 and 5 are linked, as well as channels 2&5, 3&6 and 4&8.
In the Routing screen, the user can select the input channels that are going to “feed” each output. In the
image above, channels 1 to 4 use input A, and channels 5 to 8 use input B.
For each of the outputs, the user can edit the level, delay, phase (polarity) and channel name.
On the left side are shown the 4 possible inputs with the same parameters to be adjusted, level, delay,
phase (polarity) and name.
There are different “pages” to access to all the parameters in the processor:
Routing, Limiters, EQ, DEQ, GEQ, Presets, System, Monitor.

Dynamic EQ is only available in the input channels (A, B, C, D).
Dynamic EQ block is basically a compressor or expander that can be set to respond and act upon only a
certain range of frequencies. Its behaviour is dependant on the operating mode chosen (4 modes) – two
of these are relatively traditional, whilst two modes offer the possibility to turn the normal action of
compressors and expanders on their head to allow innovative adaptive control of the program material.
Dynamic EQ modes:
Boost above, frequency 2kHz:
Cut above, frequency 2kHz:
18 E11EVEN SOUND \ IO-48 \ User’s Manual
Cut Above:
When signal level has reached the threshold, all
frequencies around 2kHz are going to be lowered by
-6dB.
Signals below the threshold will pass unaltered, but
as increasing signal is applied, those frequencies
centered around 2kHz will be cut or compressed.
This mode should be used in any instance where the
desired result is to control a band of frequencies,
such as de-essing, or de-popping, without affecting
the surrounding frequency ranges.
Boost Above:
When signal level is over the threshold, all
frequencies around 2kHz are going to be boosted
+6dB.
This mode is useful when the user wants to
emphasize certain frequency range, for instance,
voicing around 5kHz.

Boost below:
As the signal drops below the threshold,
the selected band of frequencies will be
progressively boosted in relation to the
rest of the spectrum, offering a perceived
‘lift’ in the band. Signals above the
threshold pass unaltered.
One of the best uses of this mode is in the
area of voice levelling and clarification.
Cut below:
In this mode the dynamic EQ will act by
cutting any frequencies present in that
drop below the predetermined threshold.
Reducing the level of high frequency noise
can be effectively implemented in this
mode. Particularly effective on percussive
material, unwanted tape noise and
interference can be usefully removed
without affecting the signal at normal
levels.
