High Performance Electronic Crossover.
Assembly of DeLuxe Cabinet
The high performance crossover kits have a cabinet, front
panel controls, rear panel connectors and power cord.
The kits also include a PS10-K power supply. The 2 way
units also have two crossover boards. The 3 way units
have 4 crossover boards.
The assembly of the four different models is very similar.
The differences between the four models will be
indicated in the text where appropriate.
Assembly of Rear Panel
The rear panel holds the RCA connectors and the power
cord and the fuse holder.
Install the 6 ( 8 for 3-way)
RCA connectors
in the holes
input, high pass, low pass. The 3-way unit also has two
connectors in the holes marked mid. The left channel has
the connectors with the BLACK insulators. The right
channel gets the RED insulators. Each connector has two
insulators, one with a shoulder and the other is flat. Make
sure the shoulder is inserted in the hole of the panel.
Install the flat insulator on the other side of the panel.
Install the solder lug and the nut. Tighten the nut well.
Attach
wires
to the RCA connectors. Prepare 4 (6 for 3-
way) pairs of wire by taking a 10" length of red and brown
wire and twisting together. Slip a 3/4" length of heat shrink
tubing over the end of each wire at one side of the pair.
Strip 1/4" of insulation off each wire. Solder the brown wire
onto the solder lug of the connector. Solder the red wire
into the center pin of the connector. Slip the heat shrink
tubing over the solder joints. Shrink the tubing with a heat
gun. If no heat gun is available use the heat of a soldering
iron.
Repeat this for all RCA connectors.
The two way units come with detachable line cord and a
power voltage selector switch. The 3-way units have an
attached line cord.
Please use the appropriate instructions below.
Attached line cord
Install the
fuse holder
in the panel. The white washer is
installed on the outward side.
Gently
tighten the nut. Too
much force will crack the housing.
Install the
line cord
using the strain relief. Place the strain
relief 9" from the end of the line cord and squeeze tightly
with pliers. Insert the cord and strain relief into the hole in
the rear panel until it snaps in.
The assembly of the rear panel is now complete. Put it
aside until later.
Removable line cord
Install the voltage selector switch using the 6/32 hardware.
Install the power entry module using the 6/32 hardware.
Install the fuse holder. The assembly of the rear panel is
now complete. Put it aside until later.
Assembly of Shell
First assemble the PS10-K power supply and the XM9 or
XM16 crossover boards according to the instructions
provided.
Note:
(1)
Do NOT install the board mounted
RCA connectors that are normally provided with the
crossover kits. They are not used in the high performance
crossover.
(2)
Replace the LF353 op amps with the better
op amps. On the XM9 boards the OPA2134 is inserted in
positions IC1, IC2, IC3 and IC4. On the XM16 the
OPA2134 is inserted in positions IC1, IC2, IC3, IC4, IC5
and IC6. Please make sure that the IC's are installed
correctly.
Place the shell on a flat surface with the bottom down.
Notice the pattern of four holes near one side of the
bottom of the shell. Place the shell so that this pattern is
on the left hand side. The front of the cabinet is now
towards you.
Install the
PS10 power supply
with 4 standoffs in the 4
holes on the left of the cabinet, as described above. The
two position terminal block of the PS10 faces towards the
rear of the cabinet.
The
crossover boards
will now be installed temporarily.
Notice the 4 rectangular patterns of 10 holes in bottom of
the shell Each pattern hold a crossover board. The
