Input, Midstage, and Output Pads
Install model JXP-*B pads to attenuate the signal per system design drawings. Generally, this
consists of attenuating excessive input levels. You should pad the input to system level for unity
gain. Select and install the specified pad in the socket labeled
gain. Select and install the specified pad in the socket labeled
JXP IN
on the amplifier cover.
The midstage pad (JXP) and output pads (JXP OUT, JXP 1, JXP 3, and JXP 4) can be used to
adjust the gain level and achieve the gain specification. Refer to Section 6, “Operating Tips” for
adjust the gain level and achieve the gain specification. Refer to Section 6, “Operating Tips” for
midstage/output padding information and recommendations.
