Setup and Settings Guide
The V-44SW is set at the factory so that if video is input via both the S-VIDEO IN connector and the COMPOSITE IN
connector for the same channel, the S-VIDEO IN connector’s input takes precedence.
●
If you want to give priority to the input from the COMPOSITE IN connector, select the input channel with “2. SD Input” in the menu, then
set “1: SD Input Select” to “Composite.” For more on menu operations, refer to “Working with the Menus” (p. 27).
The V-44SW is set at the factory to determine the format of video input through the HD/RGB IN connectors automatically.
●
If you want to specify the video format for the HD/RGB inputs, select the input channel with “3. HD/RGB Input” in the menu, set “2: Input
Format” to “Manual,” then select the video format with “2: Input Format.” For more on menu operations, refer to “Working with the Menus”
(p. 27).
The V-44SW’s RGB input is not compatible with the “sync-on-green” signal format.
You can link the V-44SW’s HD/RGB IN and HD/RGB LOOP THRU OUT connectors for
the same channel.
For example, if you are inputting analog component signals to the HD/RGB IN connector
on Channel 1, you can output the same signals from the Channel 1 HD/RGB LOOP
THRU OUT connector. This function is referred to as “
loop thru
.”
You can use loop thru to take the video from each input and output it directly to a
television monitor to confirm the images or when using the V-44SW as a slave device
with Multi-Screen output (p. 44).
When using loop thru, set the [TERMINATOR 75
Ω
] switch to OFF.
•
Set the [TERMINATOR 75
Ω
] switch to on when loop thru function is not used
When not using loop thru, some devices will not function properly unless the
[TERMINATOR 75
Ω
] switch is set to ON.
•
Using loop thru more than twice or more in the same pass causes attenuation of the video.
In connecting V-44SWs and V-440HDs using loop thru, once you have three or more devices connected, the video
signals become more attenuated the further down the signal path the V-44SW or V-440HD is. When using identical video
with three or more V-44SWs and/or V-440HDs, be sure to use a commercially available video multiplexer.
You can use a D-sub to 5-BNC cable to connect the component inputs and outputs.
Depending on the circumstances of a particular setup, you may experience a discomforting sensation, or perceive that the
surface feels gritty to the touch when you touch this device, microphones connected to it, or the metal portions of other
objects, such as guitars. This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are
concerned about this, connect the ground terminal (see figure) with an external ground. When the unit is grounded, a slight
hum may occur, depending on the particulars of your installation. If you are unsure of the connection method, contact the
nearest EDIROL/Roland Service Center, or an authorized EDIROL/Roland distributor, as listed on the “Information” page.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
