SAFETY PRECAUTIONS

Terminals marked with the lightning symbol carry electrical current of sufficient magnitude to constitute risk of electric
shock. Use only high quality cables with plugs pre-installed. All other installation or modification should be performed
only by qualified personnel. This symbol, wherever it appears, alerts you to the presence of un-insulated dangerous
voltage inside the enclosure - voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it
appears, alerts you to important operating and maintenance instructions in the accompanying literature.

Please read the manual.

Caution:

To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside.
Refer servicing to qualified personnel.

Caution: To reduce the risk of fire or electric shock, do not expose this appliance to rain and moisture. The apparatus
shall not be exposed to dripping or splashing liquids and no objects filled with liquids, such as vases, shall be placed on
the apparatus.

Caution: These service instructions are for use by qualified service personnel only. To reduce the risk of electric shock do
not perform any servicing other than that contained in the operation instructions. Repairs have to be performed by
qualified service personnel.

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produce

heat.

9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for

replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.

11. Use only attachments/accessories specified by the manufacturer.

12 . Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus.
When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged

in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

15. The apparatus shall be connected to a MAINS socket outlet with a protective earthing connection.

16. Where the MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall

remain readily operable.

17. Correct disposal of this product: The wheeled bin symbol indicates that this product must not be disposed of
with household waste. Please refer to the WEEE page of this manual.

THANK YOU

Thank you for choosing an E11EVEN Sound product for your application. Please spend a little
time reading through this manual so that you can obtain the best possible performance from
the unit. All E11EVEN products are carefully designed and engineered for cutting-edge
performance and world-class reliability. If you would like further information about this, or
any other E11EVEN product, please do not hesitate to contact us.

UNPACKING THE UNIT

After unpacking, please check the unit carefully for any damage. If any is found, immediately
notify the carrier concerned - you, the consignee, must instigate any claim. Please retain all
packaging, in case of future re-shipment.

INSTALLATION

- Electrical Considerations:

The iO-48 device has been manufactured to comply with your local power supply
requirements, but before connecting the unit to the supply, ensure that the voltage (printed
on the rear panel) is correct, and that a main fuse of the correct type and rating has been
fitted. Make sure power outlets conform to the power requirements listed on the back of the
unit. Damage caused by connecting to incorrect AC voltage is not covered by the warranty.

- Mechanical Considerations:

To ensure that this equipment performs to specification, it should be mounted in a suitable
rack or enclosure. When mounting the unit in a rack or enclosure, ensure that there is
adequate ventilation. The cooling fan sucks cool air in through the right side and blows warm
air out of the left side of the unit through the ventilating grills. Take care when mounting
other equipment in the same rack.

- Operation:

Read all documentation before operating your equipment and retain all documentation for
future reference. Do not spill water or other liquids into or on the unit and do not operate the
unit while standing in liquid. Do not block the fan intake or operate the unit in an
environment that could impede the free flow of air around the unit. If the unit is used in an
extremely dusty or smoky environment, it should be cleaned of any collected debris at
regular intervals.

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.

Real time LED output meters show level from the limiter threshold in 4-segments... Signal present, 6dB
below limiter threshold, Limiter threshold and 3dB into limiting. Note: The red limiter +3 LED will also
illuminate if this output is muted.
