V. REPLACEMENT OF NETWORK UNIT
Remove all of the speakers according to
Item 2.
Remove all screws from the back board.
Now, the board is still held to the back of
the cabinet by 4-pinch clips inside of the
cabinet, two on the upper side and two on
the lower side.
Remove the back board by gently rapping
on both its upper and lower sides through
the opened speaker hole in the baffle.
After removal of the back board,disconnect
all lines.
The network is secured firmly by means
of a binding agent as well as tackers. If
only a coil or a capacitor has been damaged,
it is advisable to renew only the damaged
part. Should the network be replaced, insert
a minus screw driver or the like, between the
back panel and the network and, gradually,
remove the network.
While attaching the network board to the
back board, secure it tightly using a binding
agent as well as tackers.
If tackers are not available, wood screws
wili do.
After the network has been exchanged and
attached to the back panel, re-connect all
wires to their respective terminals again.
Insert the panel into the cabinet frame
again, and screw it tightly to the cabinet.
VI. REPLACEMENT OF INPUT TERMINALS (BLUE AND WHITE)
a. Remove the middie range speaker according
to Item 2-II
Remove screws with a plus screwdriver from
the opened speaker hole shown in the
photo
b. In so doing, care should be taken not to
drop the screws.
Then, the terminal can be replaced.
The leads should be connected to the re-
spective terminal side,
Blue terminal is for the positive and White
one is for the negative terminal,
After connection of the terminals, apply a
binding agent or the like on the screws to
prevent them from loosing.

r . 12"WOOFER
a. Remove screws holding the speaker, and
pull it out gently toward you. (Photo 1),
b. Pull the Blue and White speaker leads off
from the speaker terminals. (Photo 2)
c. Mounting of NEW speaker. Push the Blue
lead end onto the Red terminal. Mount
the NEW speaker onto the baffle board.
Screw speaker tightly onto the baffle board.
II. 5''MID-RANGE
a. Remove screws holding the speaker, and
pull it out gently toward you.
b. Pull the Green and White leads off from
the speaker terminals
c. Mounting NEW speaker. Push the Green
lead female end onto the Red side male end
of the speaker terminal. Then, mount
the NEW speaker onto the front baffle
board. Screw the speaker tightly onto the
baffle board.
ru. MULTI-CELLULAR HORN TYPE SPEAKER
a. Remove screws holding the speaker, and puil
it out gently toward you.
b. Pull the Red and White leads off from the
speaker terminals.
c. Mounting of NEW speaker. Push the Red
lead female end onto the Red side male end
of the speaker, and push the White lead
female end onto the other male end of the
same speaker terminal.
Then, mount the NEW speaker onto the
baffle board.
Screw speaker tightly onto the baffle baord.
V. CARE TAKEN TO REPLACE A SPEAKER
The speakers of low and middle ranges are
of the cone type; hence, if their cone or
cap should become damaged, the tone
quality will be affected significantly.
Therefore, carefulness should be used while
removal from cabinet and, again, installed
in the cabinet.
Viewing it from the back side, the terminals
are always to identify the bottom side of
the horn speaker. The positive terminal
(Red side) is always to the right side of the
speaker and the negative terminal is always
to the left side of the speaker.

5. OPERATIONAL CHECKS
Your speaker system should be checked by the
following procedures
1. Connect the test equipment ai-ranged as
shown in Fig. 1.
2. Set the INPUT SELECTOR switch to
FULL RANGE.
o- When an 8kHz/2V-sine wave from the
oscillator is transmitted into the FULL
RANGE INPUT terminals, the tweeter
should sound well.
When a 2kHzl2V-sine wave from the
oscillator is transmitted into the FULL
RANGE INPUT terminals, the mid-range
should sound well.
When a 4ooHzl2Y-sine wave from the
oscillator is transmitted into the FULL
RANGE INPUT terminals the woofer
should sound well.
Be sure that each speaker (tweeter, mid-
range, and woofer) sounds well-balanced
in each range when sine waves from the
oscillator are transmitted into the FULL
RANGE INPUT terminals in a range
from 35 to 20,000H2.

7. In checking Items 3 and 6, be sure that
HIGHS keep sounding well-balanced while
the level control for highs is being grad-
ually turned,
8. In checking Items 4 and 6, be sure that
MID-RANGE keeps sounding well-bal-
anced while the level control for the MID-
RANGE is being gtadually turned.

10. TYansmit an output from the test equip-
ment into HIGH RANGE.
11. Check ltems 3, 4 and 7.
72. Transmit an output from test equipment
into LOW RANGE.
13. Check Item 5.
74. Set the INPUT SELECTOR switch to
3.CH MULTI.
15. Transmit a sine wave into HIGH RANGE
to check Item 3.
