MODEL 44 INSTRUCTION MANUAL
General description
The Model 44 is a four input by four output video
plus stereo audio routing system.
The Model 44C is a four input, four output by three
channel (RGB or YUV) component video router.
The Model 44CPW is a four input, four output by
four channel (RGB plus Sync) 200 MHz compo-
nent video router.
All three models are described in this instruction
manual. The routers include RS-232 serial con-
trol. The ASCII protocol used is compatible with
the protocol used in all other SVS routers. The
Model 44’s can be configured with a variety of
control methods:
• Local front panel pushbutton control with 16 re-
legendable LED illuminated switches.
• Remote control panel pushbuttons with 16 re-
legendable LED illuminated switches, including
15M interconnect cable. Cables up to 150M are
available.
The electronics for the SVS Model 44’s are
contained in a 1.75" high EIA standard 1RU high
rack mountable frame. All the circuitry is on a
single plug-in circuit board.
Installation
Carefully unpack the system. If any damage to the
unit is observed, immediately contact both the
shipping company and SVS.
The Model 44’s produce almost no heat, so they
can be mounted next to other equipment without
the need to allow space for cooling. Their shallow
depth (8.5") allows the space behind the Model
44’s to aid in the cooling of deeper heat producing
equipment above or below it.
The Model 44 is intended to be mounted in a
standard 19" metal equipment rack.
Power supply
Power for the Model 44’s is provided by an
external outlet mounted transformer (115VAC
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 44 labeled “PWR.”
Audio connections
Audio connections on the rear of the Model 44 are
made via terminal strips. Each input and output
signal consists of 3 connections: +, -, and G for
ground. The terminal strip design is a type that
directly accepts the stripped end of a wire without
attaching any type of lug to the end of the wire.
When using stranded wire it is easier to handle the
wire if the stripped end is tinned to prevent stray
strands from touching other wires.
If the audio source is unbalanced (one wire with a
shield), connect the single wire to the “+” terminal
and the shield to the “G” terminal. Leave the “-”
terminal open.
If the audio source is balanced with no shield,
connect the two wires to the “+” and “-” terminal
and leave the “G” terminal open.
Video connections
The Model 44VS and Model 44C routers have
“looping” video inputs. This means there are two
BNC connectors associated with each input.
Connect your source video to either BNC. The
second BNC associated with each used input must
either be terminated behind the Model 44 with a
75 ohm termination or the signal which appears
on this parallel connector continued on to a device
which is terminated with 75 ohms.
