USER MANUAL
1 TECHNICAL DESCRIPTION:
The STV series has amplifiers of 2 and 4 Class AB channels with direct
output (without transformer) at 100V. Available configurations are for 2 200W,
400W or 800W channels, and 4 200W or 400W channels.
Each amplifier channel includes connected loudspeaker line monitor and
protection functions against over-heating, clip and short-circuit, in addition to
forced ventilation at variable speed.
The STV series has a graphical screen on the front panel that allows
configurating operation parameters, and the control and monitoring of the
equipment. It also includes three general indicators: on/standby, link Ethernet
(only for ETX-1 and ETX-1CN), and active priority input, and two indicators per
channel: presence of signal/clip and state of channel (indicates 3 different
states).
All versions comply with standard EN-UNE 60849 regarding voice
evacuation systems, since the operation of the audio channel, from the input to
the output of the amplifier, is monitored with and without input signals to the
system, therefore ensuring that it is available during an emergency.
All models have DSP per channel for audio control. In addition to the 2 or
4 inputs depending on the number of amplifier channels, they also include a
priority input activated by means of an external operation.
The entire series includes an expansion bay to assemble remote control
and monitoring modules through Ethernet (ETX-1), or direct audio inputs
through CobraNet (ETX-1CN). This module also includes the features of model
ETX-1.
The dimensions of all products are the same for all possible channel
configurations, and can be installed on 2 19” rack units.

2 DESCRIPTION OF CONTROLS:
2.1 BEFORE SWITCHING THE DEVICE ON:
1- Make sure that the power supply circuits are properly dimensioned and
that the power voltage is stable. To dimension the circuits, check the
technical characteristics of the specific model.
2- Make sure there is correct air circulation from the front of the device
towards the back, and avoid obstructing the air flow. This device has
forced ventilation at variable speed depending on the dissipation needs,
in order to maintain the best operation temperature. Blocking the air inlets
or outlets can cause overheating of the device. In case of overheating the
system will protect itself by cutting the audio signal until it recovers the
optimum operating temperature.
3- Check that the loudspeaker lines connected to the amplifier channels
exceed the minimum specified impedance for nominal channel power.

2.2 DESCRIPTION OF CONTROLS. FRONT PANEL:
1- Drill holes for assembly on 19” rack
2- “On / Standby” indicator
“Standby”: The indicator light will be red. In this condition the device will
wait for the amplifier channels to be switched on. The unit’s control and
monitoring elements remain active, allowing the configuration of all the
operation parameters. This state is the same if the device is controlled
remotely through an ETX series expansion module. In this mode, the
level of consumption remains low.
“On”: The indicator light will be green. Before indicating “on”, the amplifier
will check the whole system. If everything is correct, then it will go “on”.
3- “Priority” indicator: In normal operating mode, it will remain switched
off. When the priority audio input is activated, the indicator light will be
green.
4- “Link” indicator: In case the system uses an expansion module of the
ETX series, the light will be orange to indicate that there exists correct
communication with the LDA remote control system.
5- 128x64 LCD Screen: It allows controlling and monitoring the system
locally. It has contrast and intensity control, and also incorporates
dynamic backlighting correction depending on the lighting of the place
where the equipment is located, thus providing optimum display
conditions. It includes screensaver configuration and turn-off timer to save
energy.
6- Navigation control: It consists of five keys, four for direction and one for
confirmation to navigate through the system’s configuration and
monitoring menus. Any parameter that needs to be modified must be
confirmed by pressing the “OK” key.

pressed the previous state is recovered by pressing the “ESC” key.
8- Air inlets for forced ventilation of the amplifier channels, and general
temperature of the device
9- “CLIP/SIGNAL” and “STATUS” Channel indicators:
“CLIP/SIGNAL”: Indicates the signal level of audio channel X. A green
light indicates a normal level of audio signal output; an orange light
indicates a high output level, and a red light indicates “CLIP” output
signal.
“STATUS”: Indicates the status of the amplifier channel:
-If the indicator light is red continuously: The amplifier channel is in the
mode due to some problem detected during its operation. In this case,
check that there is no problem of overheating by monitoring the
temperature with the appropriate menu. If the problem is overheating,
check that the connected voltage corresponds to the unit’s specifications,
and that the air inlets/outlets are not blocked or obstructed. If the problem
is not due to overheating, turn the system off by pressing the “power”
button on the back and contact the LDA Authorised Technical Service.
If the indicator light is red intermittently: It indicates a transitory channel
state due to some problem detected in the loudspeaker lines with which
the amplifier channels are loaded. In this case, check that the
loudspeaker lines are not diverted or in short-circuit.
If the indicator light is orange: The amplifier channel does not have any
load, the load is of very high impedance, or the loudspeaker line has an
open-circuit fault.
If the indicator light is green: The amplifier channel is working in optimum
conditions.

4 WORKING DECRIPTION:
4.1 PRIORITY INPUT:
The amplifiers of STV series include a priority input, at least, which is activated
by means of manoeuvre or by noise-door -- setting threshold--. If the priority
input is activated, the Priority indicator shows it from the front panel. At this
moment, all amplifiers channels conmute with this input. Then, these channels
will return to the previous status if the shoot condition turns to Stand-by.
If the amplifier of STV series has got an ETX-1CN module placed in, it will have
two priority inputs. One of these inputs is the same which is described below
and the another one is due to CobraNetTM, where all the channels will conmute
with if the audio signal is detected. The channels will return into their previous
status when the condition be on Stand-by. The priority levels are selected from
the most priority to the less priority, they are Priority Input, Priority Input via
CobraNet TM and audio input for the corresponding channel.
4.2 SETTING BY USB:
STV series amplifiers have a USB port in order to make easy the parameters
setting. The setting interface needs the Driver required for each Operative
System -- MICROSOFT WINDOWS XP / VISTA / 7 (32bit) / 7 (64bit)--.

5 ETX SERIES MODULES:
5.1 TECHNICAL DESCRIPTION:
The expansion modules of the LDA ETX series allow the STV series to
enlarge their integration and connectivity features. Both modules are insertable,
exchangeable and easy to install in the system, thanks to a sole 40-wire ribbon
cable connector with polarity.
5.1.1
ETX-1 MODULE:
The ETX-1 module enables controlling and monitoring the STV series
monitors through Ethernet. All the functions of the amplifier, controlled with the
front panel menu, can be remotely operated.
When an amplifier of the STV series is controlled remotely, the local
controls (located both on the front panel and on the back) remain blocked.
If the remote control communication is established correctly, this will be
indicated by the “Link” LED on the amplifier’s front panel.
31

USER MANUAL
5.1.2
ETX-1CN MODULE:
The ETX-1CN module includes all the features of the ETX-1 module. It
also allows fitting the STV series amplifiers with direct CobraNetTM inputs.
When an ETX-1CN module is connected to an STV amplifier, the
CobraNetTM audio inputs are selected as default inputs to the amplifier channels.
These audio inputs can be changed to analogue by means of remote
configuration.
The ETX-1CN module has two “COBRANET” inputs, a main one and a
reserve. When the first input (on the left) losses communication with the
network, for example because a switch has fallen, the ETX-1CN module will try
to connect through the second “COBRANET” input. This is useful to ensure
greater security in case of digital audio network redundancy.
The ETX-1CN module can be configured from the equipment’s front panel
or remotely.

8 AVERAGE TIME FOR REPAIRING , MTBF:
The event or average time for repairing curve shows that the failure
concentration is located at the beginning and at the end of this life-time curve.
For that reason, the average time for repairing could be calculated. This curve
could be modified due to changes in the environment, it is recommended to put
attention in the changes of external agents over the installation.
The same techniques and standards are used since the maximum level of
difficulty to the minimum level, it means to the last level of each components.
This complete study over the esteemed average time and life-time allows to
obtain a rate, which will be applied for the final product. The rate could be
calculated by different standardized equations for obtaining the esteemed lifetime, being this result modified to become in a real value. This real value is
conditioned by real working time of components and electrical and physics
stress under normal working.
The theoretical result is modified by real tests and corrections through out
a serious control of failures. All failures are controlled and registered for each
product in order to compare the precision of the calculated previsions. The
horizontal distribution allows to detect the failure in other equipments before the
failure appearance.
Next table stores different equipment models together with their
esteemed average time for repairing following the calculation described below:
