T112 STAND-ALONE OPERATION
USER MANUAL
1. T112 Stand-Alone Graphical User Interface Overview
1.1 Introduction
One way to use the TitanONE T112 is as part of a system where it is configured and controlled by GCK. However, it is
also possible to user the T112 in a stand-alone application. In this case, system configuration and monitoring can be
accomplished via the built-in web pages. This user manual describes the operation and use of this graphical user
interface.
Note, one should be careful when accessing this interface on a T112 frame that is part of a GCK system,
as any changes made via the web pages may conflict with settings made from GCK and therefore may
interfere with proper operation as part of the GCK system.
Use of the web page user interface is explained in the bulk of this document. The T112 also has a two-line display on its
front, along with navigation buttons. Operation of this user interface is covered in the installation manual (Doc: 1225B).
1.2 Getting Started
To access the T112 GUI (Graphical User Interface), one should enter http://w.x.y.z into the address bar of a web browser,
where w.x.y.z is the IP address of the frame. From the factory, the T112 comes without a fixed address, but will obtain
one from a DHCP server on the network. One can find the current address of the T112 frame by using the front panel
interface to read back the current IP address (or optionally assign it). If one needs guidance on how to use the front
panel, see the appendix. The first screen that should appear is the login screen as shown below.
From the factory, the T112 comes with the following login account:
Username: ied
Password: ied
Note, Username and Password are case sensitive, so one should enter them exactly as shown. After entering both, one
can click on the Login button, or hit the [Enter] key on the keyboard to login. This should take one to the Main Screen.

3. Amplifier Channel Configuration Screen
The Amplifier Channel Configuration Screen can be accessed for any of the 12 channels in the system 1A, 1B, 2A, 2B,
etc. and appears as shown below. The sections on this screen and the indicators/controls are described below.
/Priority Input Panel / Non-Priority Input Panel
These controls are used to configure the priority audio input and non-priority audio input. The non-priority input is
typically something like background music (BGM). The priority input is typically something like a paging input or
emergency input that will duck the non-priority input audio when activated or present. The controls in these
panels are as follows:
Analog/Network Selector
Select whether the priority or non-priority audio is coming from one of the 12 analog inputs on the rear of the
T112 frame or from a network audio (Dante) channel. This choice changes the interpretation of the channel
selector on the left to be analog input channel or network audio channel.
Input Selector
This control acts like a set of radio buttons, making one selection undoes a previous selection so only one
input or another is selected as the source for priority or non-priority audio.
Level Control
This control is used to adjust the priority or non-priority input level. One may either click and drag the “knob”
in the slider control or enter a value in the edit box below.

box and then pressing the copy button. This window is closed via the X at top right. The settings are saved/ discarded
when the save/cancel button is pressed on the amp channel configuration screen from which this was launched.
Noise Source Selector
One may select either pink or white noise as the source for this channel via this selector.
Low Pass Filter Controls
One may configure the low pass filter roll-off (“knee”) frequency and level via these controls. Optionally, the filter
may be (temporarily) bypassed via the bypass selector.
High Pass Filter Controls
One may configure the high pass filter roll-off (“knee”) frequency and level via these controls. Optionally, the filter
may be (temporarily) bypassed via the bypass selector.
Third Octave Filter Band Controls
The level for each third octave filter can be controlled via the appropriate slider under the Frequency Response
graph. It may be necessary to operate the slider on the bottom to see all the available bands.
The window is closed, and the user returned to the amplifier channel screen via the close X in the upper right corner.

4.1 Analog Input EQ Settings Window
There are five bands of parametric equalization available on each analog input. These can be adjusted via the controls
on shown in the example below, and explained below that.
Frequency Response Graph
In this area, an approximation of the frequency response (level) is shown. This area changes in response to the
EQ band controls below it. However, the graphic area can also be used interactively. When the cursor nears one
of the plot points (dots indicating center frequency of the band), a flyover box appears that shows the frequency
and level for the band/point. One can click on the point and drag it up/down to change the level value.

Make All Flat Button
Pressing this button prompts to do the operation first with a Yes/No prompt box. If Yes is selected, then all bands
are set to 0 dB level. Filter type “None” and bandwidth 1.0 Octaves. Note, this operation is not reversible directly,
but will not be saved if one presses the Cancel button on the Amplifier Channel Configuration screen that this
launched from.
Band Type Selector
Each EQ band has a selector with the choices of none, hi pass, low pass, peaking and notch. This choice works
like radio buttons, where selecting one deselects the previous choice.
Frequency Edit Box
The center frequency or “knee” of the band (depending on band type) is entered in this edit box.
Bandwidth Edit Box
For peaking or notch type filters, this is the 3 dB bandwidth measured in octaves. (For example, a third-octave
filter band would have a bandwidth of 0.33.) The value may be typed into the box.
Level Control
This control can set the boost of cut for the band from -15 to +15 dB. One may either click and drag the box in the
slider control, enter a value in the edit box below or use the up/down arrows that appear in the edit box.
Bypass Selector
The EQ band processing can be (temporarily) bypassed via this control.
