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-0606 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.

2.2 Software Installation
1. Download software from the DSP-AEC-0606 product page at
https://www.TiGHTAV.com/. Or open a web browser and type in the IP address of
the DSP´s control interface and download the software stored on the device.
2. Double click the downloaded file and install by following the instructions on the
screen.
3. After installation is complete, launch the software by clicking the
following icon:
4. Wait for the software to launch, may take 1-15s to start.
2.3 Software Operation
After the software has opened, click ”OK” on your selected model (this startup
selection box can be turned off under “Device Settings”.

Audio DSP with AEC, 4-in/4-out analog and 2x2 USB
13
To connect to the DSP click on ”Device List” and
choose your DSP from the list. Then click
”Connect”. The software will automatically scan the
network for available DSPs. The software will be
able to find DSPs even if they are not configured
with an IP address according to the computer
network configurations as long as the DSP can be
reached.
First time setup of a DSP, the DSP will have the
default static IP-Address 169.254.10.227 with
subnet mask 255.255.0.0. Click “Set IP” button to
configure a new static IP address. If DHCP is
needed connect to the DSP then go to “Settings”
tab and select “Device settings” (see section Device
settings)
The following shows the Home Tab view of the interface using Light Mode theme.
Use button and select model to add multiple DSPs to control simultaneously.
2.3.1 File Menu
Open:The File Menu gives you the option of importing saved presets from your
computer or saving presets to your computer.
Note: This option is only available offline. To import presets from your computer to an
online DSP use the “Import Preset” feature described in section 2.3.6.

Audio DSP with AEC, 4-in/4-out analog and 2x2 USB
14
Save As:Export current preset and save on your computer.
Export All: Exports a full device snapshot with all configurations and presets. IP
settings will not be exported. Save snapshot file on your computer.
Import All: Imports a snapshot file stored on a computer.
Note: Unit will disconnect after import is done and users need to connect again.
2.3.2 Settings Menu
For the Device Settings Menu to be accessible the software and DSP-AEC-0606
must be connected.
2.3.2.1 Device Settings
Device Name: Set the name of the device and the name will display anywhere the
device is addressed. The name is saved into the hardware.
Device IP Address: Set the IP address of the LAN interface.
Gateway: Set the default gateway for the network.
Netmask: Set the network mask associated with the desired subnet.
Mac Address: Shows the MAC address of the control interface.
Note:
Default Preset: Sets the default preset the device loads upon a power cycle event.
Can be set to one of the 16 presets or set to last active preset prior to the power
cycle.

Audio DSP with AEC, 4-in/4-out analog and 2x2 USB
15
Central Control Response: Enable this when using an external controller that
expects a response to control messages (see Appendix C, Command Structure
Examples).
Real Time Save: When enabled, active preset changes are saved in real time.
Enable this will ensure the exact state of the device to be restored upon a power
cycle if ”Previous Loaded Preset” is selected in the ”Default Preset” parameter. If
Real Time Save is set to ”Off”, changes that are not manually saved will be lost after
a power cycle.
Enable Model Selection Box: When enabled, upon starting the software the model
selection window will appear.
UDP Control Port: Shows the UDP control port for remote communication with the
DSP-AEC-0606.
RS-232/RS-485: Set the baud rate, Data bit, Stop bit and Parity bit for the serial port
of the device.
OK: All settings done in the Device Setting window are saved to the device and the
window will close.
Cancel: Will close the window and no changes are saved.
2.3.2.2 Group Settings
The group setting window has separate tabs for input and output groups. 5 groups
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, 4-in/4-out analog and 2x2 USB
16
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.
2.3.2.3 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.
2.3.2.4 Panel Setting
Panel configuration page for button and OLED panels. Use network cables to
connect multiple physical panels with DSP devices via the network switch(es).
Offline devices: Panels can be configured offline for later upload on-site
commissioning.
