Precautions
Important Safety Warnings
[Power]
Do not place or drop heavy or sharp-edged objects on power cord. A damaged cord
can cause fire or electrical shock hazards. Regularly check power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Circuitry Access]
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even
after power is disconnected. Capacitors associated with the power supply are
especially hazardous. Avoid contact with any capacitors.
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.
[Potential Hazards]
If abnormal smells or noises are noticed coming from the unit, turn power off
immediately and disconnect power cord to avoid potentially hazardous conditions. If
problems similar to above occur, contact authorized service representative before
attempting to again operate unit.
[Consumables]
The consumables used in unit must be replaced periodically. For further details on
which parts are consumables and when they should be replaced, refer to the
specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
they should be replaced at an early date. For details on replacing the consumables,
contact your dealer.

1-2. Features
This is a down-converter used for monitoring applications and is available in a modular format
for installation in a UFH frame. It can convert HD-SDI signals into SD-SDI signals and analog
signals or convert SD-SDI signals into analog signals.
 Down-conversion of HD-SDI signals into SD-SDI signals and analog signals (HD or SD)
 Conversion into any of five aspect ratios (4:3, 13:9, 14:9, 16:9, squeeze)
 Selection of analog signal output enabled (YPBPR, GBR, Y/C, composite signals)
 Sync output signals for monitoring supported
 Process control functions provided (video level, chroma level, chroma phase, setup/black
level)
 Built-in cross color reduction circuit
 Selection of enhanced level enabled

No Name Description
(1)
HD/SD-SDI IN
HD/SD-SDI
OUT
The left connector is used to input a serial digital component signal
(HD/SD-SDI).
The right connector is used to output an active-through out of
HD/SD-SDI IN. The jitter in the active-through output depends on
how much jitter is included in the input video. This card module has
no jitter-reducing function.
(2) SD-SDI OUT
(1 / 2)
Used to output SD-SDI signals.
Signals, down-converted and adjusted by Proc Amp, are output if an
HD-SDI signal is input.
Proc Amp adjusted signals are output if an SD-SDI signal is input.
(3) Y / G / C1
(HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The Y (HD/SD component), G
(RGB component) or composite signal can be output from this
connector (3).
(4) PB/ B / C2
(HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The PB(HD/SD component), B
(RGB component), Y(Y/C) or composite signal can be output from
this connector (4).
(5) PR/ R / C3
(HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The PR(HD/SD component), R
(RGB component), C (Y/C) or composite signal can be output from
this connector (5).
(6) SYNC / C4 (HD/SD,
ANALOG OUT)
The signal input from (1) or the signal output from (2) is D/A converted
and output from (3), (4), (5), and (6). The composite, bi-level sync, or
tri-level sync signal can be output from this connector (6).
The FUNCTION (see previous page) on the front panel enables you to select the type of signal
output from HD/SD ANALOG OUT (see also section 4-3).
The SD-SDI OUT and ANALOG OUT connector output a down-converted signal and/or a signal
input from HD/SD-SDI IN. The available output signal formats of these two outputs for different
input signal formats are as shown in the table below. The unit may not output signals correctly if
any other signal format than those listed below is used to input to the unit.
