House connection amplifiers for modern HFC networks up to 1 GHz
Integrated high-efficiency switched-mode power supply unit
Power management: Unused amplifier stage switch-off for reduced power consumption
Die-cast housing with F-type connectors
Variable 6 dB interstage gain setting using on-board plug-in attenuators (delivery condition: higher gain)
The maximum operational levels also apply for operation with interstage attenuation
Interstage equaliser switchable with bridging plugs (6 dB pre-emphasis)
Integrated return path 5-65 MHz active/passive, off (switchable with bridging plugs)
Built-in variable attenuators (delivery condition return path: max. attenuation) and variable equaliser
LED to indicate operational mode

The amplifiers comply with the EMC directive 2004/103/EC and Low-Voltage Directive 2006/95/EC applicable at the time of shipping.

Test socket on output -20 dB (with directional coupler)
Test socket on input -20 dB
Test sockets are terminated with the EMK 03 in the delivery status
Conform to: EN 60728-11, EN 50083-2 and EN 60065
For indoor installation

Basic safety precautions

• Installation must be carried out by authorised specialist staff.
• Unplug from the mains before installation.
• Described amplifiers are exclusively for installation of HFC networks up to 1,006 MHz.
• Any other use or failure to comply with these instructions will void the warranty or guarantee.
• The amplifiers may only be installed in dry areas indoors. Do not install on or against highly combustible materials.
• The amplifiers must be earthed when installed (Cu, minimally 4mm^2 ).
• The safety regulations set out in the current EN 60728-11 and EN 60065 standards must be complied with.

• The supply voltage of the amplifiers is 230 VAC which can be fatal if touched directly.
• The only reliable method of disconnecting the amplifiers from the mains is to unplug them.
• Do not touch live parts.
• The power plug must be easy to operate as the means of cutting power to the amplifier, so the wall outlet must be close to the amplifier and easily accessible.
• The amplifiers may only be installed and deinstalled in the voltage-free condition.
• Do not operate the amplifiers without the factory-fitted protective cover over the power supply unit. The cover must be closed.
• No liquid-fi lled items may be placed on top of the amplifiers.
• The amplifiers are not to be exposed to dripping or splashing water.
• Ambient temperature range -20 to +55°C

Setting of the amplifi er

To adjust the settings, a Phillips screwdriver is required to remove the housing cover. The settings options are also imprinted on the housing cover.
