Important: Setting the output power

The total band power (approx. 90 transponders) is 19.5 dB higher compared to the output power of a single transponder determined with a measuring device!

You must take this into account when making the setting!
Example 1
1 transponder:
80.0 dBµV measured
90 transponders:
99.5 dbµV Band power

The LED display on the unit shows 99 dBµV.

Result: The input signal can (only) be amplified by 10 dB.
Example 2
1 transponder:
90.0 dBµV measured
90 transponder:
109.5 dbµV Band power

The LED display on the unit shows 109 dBµV.

Result: The input signal cannot be amplified any further.
Consideration for 5 flush-mounted boxes in the line:

    Good television reception requires 60 dbµV - 75 dbµV at the input.
    An EOC 1000/EOC 2000 flush-mounted box has a throughput attenuation of 2-3 dB and an outcoupling attenuation of 18 dB.
    The AMP X8 delivers a maximum of 110 dbµV per line.

After 5 EOC 1000/EOC 2000 flush-mounted boxes connected in series, the total attenuation is:
4x3
dB
Continuity attenuation
+
18
dB
Outcoupling attenuation
+
4x1-2
dB
Attenuation in coaxial cable
=
34-38
dB
Total attenuation

An optimum setting on the AMP X8 would then be:
60 bµV-65 dbµV + 38 dB = 98-103 dbµV.

The output of the first socket would then be 12 dB, i.e. 72 bµV-77 dbµV.
