Network Connection
The network input terminals should be connected
to the amplifier loudspeaker outputs. Connect the black terminal ot general
application networks to the negative amplifier output, and the red terminal
to the positive amplifier output Heavy-duty networks are provided with
screw terminals The input terminal located on the white line, marked "C"
lor common, should be connected to the negative amplifier output;
connect the other input terminal to the positive amplifier output.
General application networks have eyelets thai allow lead wires to pass
through the flange into the enclosure and at the same time maintain an
airtight seal. The LX30, however, has screw terminals on the back of the
control assembly. Color-coded wires are provided, although any 18-gauge
insulated wire can be substituted. The proper wire gauge for the amplilier
connection is discussed under Amplifier Connection
Connections between the network and the components are illustrated
in the accompanying diagrams, as indicated in the Network Selection
Chart Care should be taken to follow the diagrams exactly to ensure that
components will operalo in the proper phase relationship with each other.
Note that high frequency compression driver phasing is a function of the
crossover frequency as well as the horn/lens assembly utilized. The wiring
illustrations are correct when an HI.87. HL91. HL92 or HL93 is mounted on
the enclosure baffle panel, and when an HL88. HL89 or I1L90 is positioned
so that the horn mouth is flush (even] with the enclosure baffle panel. If the
horn/lens assembly is moved more than six inches toward or away from
the listener (with respect to the mounting conditions just outlined), install a
phase reversing switch fdoscribed on page
24)
and audition male vocal
material while changing phase of the high frequency driver. Utilize the phase
condition which yields the most natural reproduction.
