SAFETY PRECAUTIONS
Please read this manual before installing or using the product. Review the following
safety precautions.
The lightning symbol in the triangle is used to alert you to the presence of dangerous
voltage inside the product that may cause a risk of electric shock to anyone opening the
case. It is also used to indicate improper installation or handling of the product which could
damage the electrical system of the product or other equipment connected to the product.
The exclamation point in the triangle is used to alert you to important operating and
maintenance instructions. Failure to follow these instructions may result in injury or
product damage.
Be careful with electricity:
Power Outlet: To avoid electric shock, make sure that the electrical plug used on
the product power cord matches the electrical outlet used to supply power to the
TiGHT AV product. Use the power adapter and power connection cables designed
for this unit.
Power Cord: Make sure the power cord is routed so that it will not be walked on or
pinched by heavy objects.
Lightning: To protect against lightning or when the product is left unattended for a
long period of time, unplug it from the power source.
Also follow these precautions:
Ventilation: Do not block the ventilation slots, if any, on the product or place heavy
objects on it. Blocking the airflow could cause damage. Arrange the components so
that air can circulate freely. Ensure adequate ventilation if the product is placed on a
stand or cabinet. Place the product in a well-ventilated place, away from direct
sunlight or any heat source.
Overheating: Avoid stacking the DSP-AEC-1410 on top of a hot component, such
as a power amplifier.
Risk of Fire: Do not place the unit on top of easily combustible materials, such as
rugs or fabrics.
Proper Connections: Make sure all cables and equipment are connected to the unit as
described in this manual.
Object Entry: To avoid electric shock, never stick anything in the slots on the case, or
remove the cover when connected to a power supply.
Water Exposure: To reduce the risk of electric shock or fire, never expose the unit to
rain or moisture.
Cleaning: Do not use aerosol cleaners or liquid to clean this unit. Always unplug
the power source to the device before cleaning the unit.
ESD: Handle this unit with proper ESC care. Failure to do so can result in failure.

commissioning at a later stage or saving record of configurations for a finished
project.
Open…: Import a previously saved GPIO configuration file.
Save: Save the current configuration file to the DSP.
2.3.2.3 Group Settings
The group setting window has separate tabs for input and output groups. 7 groups for
input channels and 5 groups for output channels can be set in each tab. A channel
can only participate in one group. In the same group, the channel volume/gain control
and mute functions are linked. Individual level differences are kept. Other functions
are not linked. For pairwise linking of all channel parameters, use the link button
below the channel fader.

Audio DSP with AEC 12-in/8-out analog and 2x2 USB
19
The relationship between groups and link: The channel participating in a group
will not participate in LINK, which means the group’s priority is higher than LINK. The
difference between groups and LINK is that groups can only control channel gain
and mute, while LINK includes all parameters in the channel. LINK sets volume/gain
to same value whereas the Group keeps the differences set by the faders.
2.3.2.4 Preset Name
In this window, all 16 preset names can be changed
in one window.
All changes made here will correspond to other
features in the software where Preset Names are
available.
