DESCRIPTION:
- Compact RF amplifi er systems in wideband and
multiband for medium and small collectives
- Ideal for head station amplifi cation and re-
amplifi cation of the line or extension
- High gain and output level with very low dis-
tortion.
- Separate amplifi cation of FM-VHF-UHF with
independent adjustment of each sub-band

ASSEMBLY, CONNECTORS AND CONTROLS:
The amplifi er system may be wall-mounted by
simply screwing the wings "E" to plugs inserted
in the wall (refer to Fig. 1).
The same fi gure shows the location of connec-
tors and controls:
A - Multiband inputs
D - General output
C - Test output ( - 20dB)
G - Mains connection 230 V AC
B - Gain controls
F - Power supply switching to preamplifi ers

indications for the inputs, outputs and amplifi -
cation of sub-bands for each model

Possibility of interconnection with IF amplifi er
system (code. 1040A) using an input diplexer
INSTALLATION AND ADJUSTMENT
After completing the above connections, plug the
system into the 230 V AC mains power supply
(Fig1. G). Connect, if available, a signal tester to
the TEST output (Fig1. C). Adjust the controls
B to equalise the levels of the different bands
available in the installation. Do not exceed the
maximum output level for each sub-band (Refer
to note 2)
NOTES:
1 - Remember that the levels measured at the
TEST output are 20dB lower than the output used
in the installation (Fig1. D)
2 - Fig 2. shows the amplifi ers separated for
each model as well as the maximum output
level for 2 channels. For n channels at the same
level, reduce this value by 7.5 x log (n-1). If the
channels have different levels, they should be
reduced even further, until the image is correct
when viewed on the television set.
