Product description
The output amplifier UA410 is intended to amplify and summarize signals in modular system as well as stand-alone unit.
The UA410 has wide range of output level selection, which includes interstage and input gain adjustments.
Two selectable input modes: input + input test point or two inputs.
Both output and switchable input test points are directional.
The output amplifier is intended for indoor use only.
Safety instructions
Installation of the amplifier must be done according IEC60728-11 and local safety standards.
The amplifier is powered from power supply unit (PSU) +12 V. This voltage is not dangerous to life.
Output of PSU +12 V must have a short circuit protection.
Any repairs must be done by a qualified personnel.
Do not plug the PSU +12 V into the mains socket until all modules cables have been connected correctly;
The mains socket of PSU +12 V must be easily accessible;
To disconnect the amplifier, disconnect the PSU +12 V from the mains.
The amplifier shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, shall
be placed on it;
Avoid placing amplifier next to central heating components and in areas of high humidity;
No naked flame sources, such as lighted candles, should be placed on amplifier;
If the amplifier has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before
plugging into the mains;
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths,
curtains;
Mount the amplifier in vertical position;
From top, front and bottom of installed amplifier must be at least 10 cm free space.
