General description
The SVS Model 321V, 321S and 324V are a
family of small routing switchers with 32 inputs.
Optional local and / or remote panels are simple to
operate, button-per-crosspoint designs. The
electronics for each of these routers is contained
in a 1.75" high EIA standard 1 RU rack mount-
able frame. All the circuitry is on a single plug-in
circuit board.
The Model 321V includes built in RS232 serial
control. In addition to the optional remote control
panel, the Model 321V can accept an optional
local control panel in place of the blank front cover.
The Model 324V is a four bus version of the
Model 321V. For the Model 324V RS232 serial
control is an option that is built in at the factory.
The Model 324V accepts four separate 32 by 1
remote control panels.
The Model 321S can be used in either an AFV
configuration, when connected to a Model 321V
or Model 324V, or it can be used as a standalone
32 by 1 stereo audio router.
Installation
Carefully unpack the system. If any damage to the
unit is observed, immediately contact both the
shipping company and SVS.
The Model 321V, 321S and 324V produce almost
no heat, so they can be mounted next to other
equipment without the need to allow space for
cooling. Its shallow depth (8.5") allows the space
behind the Model 32 to aid in the cooling of deeper
heat producing equipment above or below it.
Power supply
Power is provided by an external outlet mounted
transformer (117VAC version only). For 220VAC
units the external transformer has a short input
cable to which the proper AC input connector
must be added. The output of the transformer is a
2M (6ft) cable with a 3 pin female DIN connector.
This mates with the corresponding 3 pin male
DIN connector on the rear of the Model 32
labeled “PWR.”
Video connections
The 32 video input BNC connectors each have an
internal 75 ohm 1% termination. Unused inputs
can be left with no connection. The Model 321V
has two identical outputs. An unused output does
not need to be terminated.
Sync connection (Model 324V only)
The Model 324V has two looped BNC connectors
labled SYNC. These may be connected to house
sync, a reference video or looped from one of the
Model 324 four outputs. If left unconnected the
Model 324V will switch at a random point rather
than in the vertical interval.
Audio connections
Audio connections on the rear of the Model 321S
are made via “D” miniature connectors. Four 25
pin connectors are used for inputs on each channel
(eight audio inputs per connector). The Model
321S has two sets of outputs (two outputs for the
right channel and two outputs for the left channel).
The pinout of all the audio connectors is shown
in Table 1.
