2-1. GENERAL
This board is a 5-BNC analog input/output board which is
able to serve as an input or output board using the IN/OUT
switch. The output board is equipped with a feed
compensation function for cable, and a compensation rate
can be selected with the compensation mode switch
according to the length of the coaxial cable.
2-2. POWER SUPPLY CIRCUIT
+12 V to +15 V power is supplied from the 96-pin
connector CN3 (A4, B4, and C4) (IFB-12 (OLD)), J1 (A4,
B4, and C4) (IFB-12 (NEW), IFB-12A) terminals. The IN/
OUT select switch is used to select the power for the input
or output circuit.
1When the IN/OUT switch is set to the IN side and CN3
(C19) (IFB-12 (OLD)), J1 (C19) (IFB-12 (NEW), IFB-
12A) becomes “LOW”, Q25 is turned OFF, Q28 is
turned ON, and relays RY1 to RY5 (IFB-12 (OLD)),
RL1 to RL5 (IFB-12 (NEW), IFB-12A) are turned ON
by IC25, and the power supply line is connected to the
input circuit as well as the LED lights up.

(A17) (IFB-12 (NEW), IFB-12A) becomes “MIDDLE”
or “HIGH” (+1.7 V to +5.2 V), Q25 is turned OFF,
Q28 is turned ON, and relays RY1 to RY5 (IFB-12
(OLD)), RL1 to RL5 (IFB-12 (NEW), IFB-12A) are
turned OFF by the comparator IC26 and IC25, the
power supply line is connected to the output circuit as
well as the LED lights up. When the RGB/VIDEO
terminal becomes “LOW” (input is a video signal), the
output circuit does not function.
3R208, Q22, Q23, and Q24 serve as a current detection
protector. When excessive current flows (higher than
1.2 A), Q22, Q23, and Q24 are turned ON, and Q28 is
turned OFF (power is shut off) as well as protector
terminal CN3 (A2) (IFB-12 (OLD)), J1 (A2) (IFB-12
(NEW), IFB-12A) is connected to GND, and failure is
indicated to the outside.
2-3. INPUT MODE
When the IN/OUT switch (S2: IFB-12 (OLD)), (SW2:
IFB-12 (NEW), IFB-12A) is set to the IN side and SEL
(C19) terminal becomes LOW, this mode is set.

1Input mode setting (Table 1)
When the DIP switch is turned ON according to the input
signal, RGB/VIDEO, VIDEO/YC, and CODE1 control
signals are passed through transistors Q2 to Q8 and output
to CN3 (A17, C17, and B16) (IFB-12 (OLD)), J1 (A17,
C17, and B16) (IFB-12 (NEW), IFB-12A) according to the
input mode. This informs external devices such as a
switcher, etc. of the input signal type.

22
2Video signal
Video signals input from the BNC terminal are passed
through relays RY1, 2, and 3 (IFB-12 (OLD)), RL1, 2, and
3 (IFB-12 (NEW), IFB-12A) and are input to +6 dB
amplifier ICs 19, 20, and 21. This input signals are usually
terminated with the 75 Zterminator switches S3, 4, and 5
(IFB-12 (OLD)), SW3, 4, and 5 (IFB-12 (NEW), IFB-
12A). When JP 1 and 2 connectors are set to the G-R and
G-B sides, only G signal is generated, and a black-and-
white image is output.
RGB signals input from ICs 19, 20, and 21 are passed
through RY7, 8, and 9 (IFB-12 (OLD)), RL7, 8, and 9
(IFB-12 (NEW), IFB-12A) and are output to CN3 (21, 25,
and 29) (IFB-12 (OLD)), J1 (21, 25, and 29) (IFB-12
(NEW), IFB-12A) terminals.
33
33
3SYNC signal
A 75 Zor 1 K Ztermination resistance can be selected for
SYNC/HD and VD signals input from the BNC terminal
using terminator switches S6 and 7 (IFB-12 (OLD)), SW6
and 7 (IFB-12 (NEW), IFB-12A).
Q10, Q11, and IC (1/2), and Q14, Q15, and IC (2/2), and
Q12, 27 (IFB-12 (NEW), IFB-12A) serve as a peak
detection circuit for SYNC/HD and VD signals. These
signals are compared with the intermediate value of the
peak value, are converted to TTL level SYNC signals by
IC3 and output to CN3 (12, 14) (IFB-12 (OLD)), J1 (12,
14) (IFB-12 (NEW), IFB-12A). Also with IFB-12 (NEW),
IFB-12A, when input signal is recognized as TTL level,
SYNC/HD, VD, which is input from BNC terminal, is
input to relay RL6 as it is, then it is output to J1 (12, 14) by
control of this relay. When the SYNC signals are used to
process signals synthesized with video signals, JP3 and 4
are set to the VIDEO side.
By switching JP5 to GS side, SYNC signals CS and VS are
input from IC2 for input signals such as SYNC ON
GREEN, Y signal, etc.
44
44
4Audio signal
AUDIO L and R signals input from the pin jack terminal
are input to the buffers Q16 and Q17, and are output to
CN3 (A7, A8) (IFB-12 (OLD)), J1 (A7, A8) (IFB-12
(NEW), IFB-12A) by the analog IC4 switch.
2-4. OUTPUT MODE
When the IN/OUT switch (S2: IFB-12 (OLD)), (SW2:
IFB-12 (NEW), IFB-12A) is set to the OUT side and RGB/
VIDEO signal level of CN3 (A17) (IFB-12 (OLD)), J1
(A17) (IFB-12 (NEW), IFB-12A) becomes MIDDLE or
HIGH, this mode is set. IN/OUT terminal of CN3 (B23)
(IFB-12 (OLD)), J1 (B23) (IFB-12 (NEW), IFB-12A)
becomes LOW and informs the outside of the output mode.
11
11
1Video signal
RGB signals input from CN3 (B3, B5, and B7) (IFB-12
(OLD)), J1 (B3, B5, and B7) (IFB-12 (NEW), IFB-12A)
are terminated with the 75 Ztermination resistors R50, 90,
and 130, and are passed through buffer ICs 7, 8, and 9 to
be distributed for four outputs. These signals become four
signals in which high-frequency is emphasized by R and C,
and cable compensation elements CR1, CR2, and CR3.
Analog switch ICs 10, 11, and 12 are used to select one
compensation rate required from these four signals
according to the mode S8 (IFB-12 (OLD)), SW8 (IFB-12
(NEW), IFB-12A). These signals are amplified by the 7
times output amplifier ICs 13, 14, and 15, are passed
through relay RY1, RY2, and RY3 (IFB-12 (OLD)), RL1,
RL2, and RL3 (IFB-12 (NEW), IFB-12A), and are output
to the BNC terminal. Q18, 19, 20, IC16, and IC17 serve as
corresponding feedback clamp circuits, detects black level
of output signals, and applies DC bias
to the output amplifier.
22
22
2SYNC signal
SYNC HS and VS signals input from CN3 (B8 and B10)
(IFB-12 (OLD)), J1 (B8 and B10) (IFB-12 (NEW), IFB-
12A) are passed through buffer IC5 (IFB-12 (OLD) only)
and relay RY4 (IFB-12 (OLD)), RL4 (IFB-12 (NEW),
IFB-12A) and are output to the BNC terminal.
33
33
3Audio signal
AUDIO L and R signals input from CN3 (B1 and B6)
(IFB-12 (OLD), J1 (B1 and B6) (IFB-12 (NEW), IFB-
12A) are passed through relays RY6 and RY5 (IFB-12
(OLD)), RL5 (IFB-12 (NEW), IFB-12A), and output to the
pin jack terminal.
44
44
4Others
When the NOR/MIX switch S12 (IFB-12 (OLD)), SW12
(IFB-12 (NEW), IFB-12A) on the board is switched to
NOR or MIX, “HIGH” or “LOW” voltage is output to
CN3 (B31) (IFB-12 (OLD)), J1 (B31) (IFB-12 (NEW),
IFB-12A) terminal. The signal type to be output (monitor
output or projector output) can be indicated to an external
switcher, etc.

ELECTRICAL PARTS LIST
NOTE: • Items marked " * " are not stocked since
they are seldom required for routine
service. Some delay should be anticipated
when ordering these items.
• All variable and adjustable resistors have
characteristic curve B, unless otherwise
noted.
When indicating parts by reference number,
please include the board name.
RESISTORS
• All resistors are in ohms
• F : nonflammable
• CAPACITORS
PF : µµ F
• There are some cases the reference
number on one board overlaps on the
other board. Therefore, when ordering
parts by the reference number, please
include the board name.
