USER MANUAL
WARNINGS:
1. Read this instruction manual before operating the device.
2. Keep this manual for further reference.
3. This device must not be exposed to water. As a precautionary measure,
objects containing liquids must not be placed next to/on top of it.
4. Do not block the system’s ventilation inlets/outlets, and do not install the
device to sources of heat.
5. If the device is going to be mounted on a frame or rack, make sure that
there is good ventilation.
6. Only use original accessories provided by the equipment’s manufacturer.
7. Unplug the device when it is not going to be used for a long period of
time.
8. Clean with a wet cloth, and do not use chemicals products.

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.

USER MANUAL
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.
