INSTALLATION GUIDELINES
This reminder is provided to call the CATV System Installer
’
s attention to Article 820
-
40 of
the NEC that provides guidelines for proper grounding and,
in particular, specifies that the cable ground shall be con-
nected to the grounding system of the building, as close to
the point of cable entry as practical.
•
Plug in Gain & Cable Slope Controls are reachable under
the Cover. Refer to layout scheme above the RF circuit
for adjustable controls.
•
This product is shipped with default 0 dB pads for plug in
gain control and equalization.
•
Connect only to power adapter supplied with the ampli-
fier.
NOTE: All gain and equalizer adjustments are achieved by universal plug
-
in JXP pads. The
amplifier actually uses standard JXP series pads in place of equalizers as well. This is due to
a unique circuit in the amplifier that effectively turns the pad into an equalizer. For instance
if you were to install a 8 dB (or any value) pad in the equalizer socket it becomes a 8 dB (or
same as pad value) equalizer ,attenuating the low frequency by 8 dB while only attenuating
the high frequency by about 1 dB.
FORWARD OUTPUT LEVEL SETUP PROCEDURE
Before applying power to the amplifier, make sure that the input level to the amplifier
is not too high otherwise a damage to the amplifier might occur. To be on the safe si-
de, you should set the input gain control adjustment to minimum gain (insert highest
pad on input ATT socket) before powering the FX.
2.
Set the input and interstage equalizer controls for minimum slope, install a 0 dB JXP
pads at the input and interstage plug in equalizer sockets (factory installed).
