LOCATION AND ENVIRONMENT
Environmental Considerations
The ambient temperature for all the supplied equipment should not exceed the limits of 5 and 35
degrees C. at a relative humidity of 10 to 90% (non-condensing).
Installing the equipment in a clean environment with moderate temperature and humidity will
promote a long and trouble-free equipment life.
Location
The SD1000 Mainframe may be used free-standing (table-top configuration) or installed in a
standard 483mm (19 inch) equipment rack. The following precautions should be observed:
a) The cooling fan exhausts at the rear of the unit must not be obstructed - a minimum
clearance of 200mm (8 inches) is ESSENTIAL.
b) The slots in the front panel are to allow the inlet of cooling air and MUST NOT BE
OBSTRUCTED.
c) When mounting the mainframe in an equipment rack it MUST be supported at the rear, not
by the rack-mounting ears alone.
Cooling is provided by drawing air in at the front of the unit and exhausting it at the rear.
The mainframe should never be operated for any significant period of time with any covers
removed as this will affect the internal airflow and cause overheating.
Control Panel Installation
The control panel is designed to stand freely on a tabletop.
If it is necessary to secure the control panel to a control desk (e.g., in an OB van) the control panel
has to be opened. This installation MUST be carried out by a qualified Installation or Service
engineer.
Battery Warnings
Empty Holder -There is an empty battery holder on the MBX card in the Control Panel, this
holder is not used.
No battery should be fitted to this card!

S&W Production & Post Production SD1012 Installation Manual - Issue 6, Rev 1 Page 5
LOCATION AND ENVIRONMENT - continued
Power Supply
All three major parts of the system - Switcher Mainframe, Router Mainframe, and Control Panel -
have the option to be fitted with dual power supplies. In each case the unit will work happily with a
single power-supply connected if required.
For safety a mains earth connection MUST be provided.
The unit has auto-ranging mains input, and can be connected to any standard AC supply between
115v and 230v 50/60Hz without adjustment.
Fusing
The control panel is protected by a 4 amp, and the mainframe by a 5 amp, anti-surge (slow-blow)
fuse located in the mains inlet / power switch assembly, see diagram below.

SYSTEM INTERCONNECTION
Introduction
Your system has been set up and tested before shipment. Installation normally consists of siting
and interconnecting the system components, connecting video and key inputs and outputs and
setting up.
Control Panel
•Remove and keep the supplied nuts and washers from the two bolts on the top of the Control
Panel.
•Remove the LCD Touch Screen module from the packaging.
•Carefully fit it over the two bolts on the top of the Control Panel.
•Fix down the LCD Touch Screen using the washers and nuts that you removed earlier.
•Secure the earth strap between the Touch Screen module and the Control Panel using the
fixings provided.
•Connect the 25-pin D connector to the similar one on the rear of the Control Panel using the
cable provided.
•Connect the 9-way D connector to the similar one on the rear of the Control Panel using the
cable provided.
•If desired, a standard VGA monitor can be plugged into the 15-way sub-D connector at the
bottom rear of the panel. The signal frequency should be acceptable to the vast majority of
VGA-compatible monitors (see Specifications Section).
•Finally, connect the 10 Base-T connector on the Control Panel to the socket on the Switcher
Mainframe marked “Panel 10 BASE TX” using the cable provided.
Power
Switch all power switches to their OFF states. Connect IEC power cables from the power socket(s)
on the rear of the Switcher Mainframe and Control Panel to the appropriate AC mains distribution
socket(s).

Inputs
Connect up to 12 SDI inputs to the 12 Serial Inputs of the Switcher Mainframe. Sources can be
either video or key. If the system has the 24 input option fitted, all input connectors can be used.
Connecting to an Alternate Mainframe
Connect the 10 BASE T socket on the rear panel of the primary mainframe (adjacent to the Panel
10 BASE TX connector) to the Panel 10 BASE TX socket on the alternate mainframe.
Referencing
The Switcher can be Genlocked to any of its Inputs or to analogue sync on the Ref Analogue In
loop-through connectors, selectable from the Configure-System-Genlock & Outputs menu.
Note that the input number set in this menu is absolute and is not remapped through the
Configure-User-Source Mapping menu.
If the incoming reference signal is not used elsewhere then the remaining Ref Analogue In BNC
should be terminated with a 75Ωterminator.
Whether the Switcher Mainframe is acting as the Master SPG for the system or is being Genlocked
to an external source, the Ref Sync Out BNC provides an adjustably-timed analogue sync output
with which to synchronise external sources.
Referencing - Input Timing
Since all inputs have framestore synchronisers, correctly positioned pictures will be obtained even if
the sources are free running. However it is recommended that the switcher and source are locked
together. This ensures constant video delay through the switcher and avoids missing or repeated
frames which will occur every time a source “runs through” a complete frame
There are two methods for referencing the switcher system.
(a) A common ‘station’ sync or black-burst reference is fed to all sources, and to the switcher. This
arrangement should be used when same sources are fed to other equipment apart from the
switcher. In this case switcher Genlock should be On, and the Genlock H/V Phase controls
adjust the timing of the switcher relative to the sources.
(b) The sources are referenced from the Ref Sync Output of the switcher. In this case the timing
of the sources is set relative to the switcher by the Sync H/V-Phase controls. This
arrangement should be used if the switcher is the master reference in the system. It can also
be used when the output of the switcher needs to be timed into following equipment; in this
case the switcher will is genlocked to a ‘station’ sync or black-burst, and the
Genlock H/V Phase will move the timing of the switcher output and the sources together.
These controls can be found in the Configure-System-Genlock & Outputs sub-menu.
Note: the Output Line-Standards must be correctly set before doing this.

SYSTEM INTERCONNECTION - continued
Referencing - System Delays
The delay through the Golden DaVE system is illustrated in the timing diagram on the next page.
With no option (OPT) card the minimum delay which is possible is 185 pixels (about 14µs), but as
the diagram shows, with a DVE card fitted a delay of over 2 frames is easily achievable!
Because all inputs have frame synchronisers, a source cannot be set outside the source window; if
a source is delayed (shifted to the right) beyond the end of the window, the whole diagram moves
one frame to the right, so the source is now at the left hand edge of the window, and the input
synchroniser is inserting a frame of delay.
To minimise lip-sync problems, it is usually preferred to minimise the delay through a switcher. If
the OPT card is fitted, the desired Border Gen Delay must be set in the Configure-System-
System Delays sub-menu, before making timing adjustments since it affects the processing delay.
Refer to the User Manual.
For example if the Border Gen Delay is set to 10 lines, the processing delay will be 10 lines +
33us. If the sources are set 11 lines in advance of the output, this will allow for the processing
delay. The sources will be at the right hand end of the source window in the diagram, and the
delay through the input synchronisers will be 64 - 33 = 31us. If the switcher and sources are locked
to a common reference (method (a) above), set the Genlock V Phase to 11 to achieve this. If the
sources are genlocked to the Ref Sync Output of the switcher (method (b) above), set the Sync
V-Phase control to 11 lines advance: 625 - 11 = 614 in 625-line standards or 525 - 11 = 514 in 525-
line standards. If the DVE option is fitted the delay will now be 1 frame +11 lines. It can be
reduced to 11 lines for paths which do not pass through a DVE by setting the DVE Delay in the
Configure-System-System Delays sub-menu to minimum; in this case there will be a time jump
when a DVE is selected or de-selected.
Outputs
Connect the four outputs Program, Clean Pgm, Preview 1, &Preview 2 to external equipment or
monitoring devices as desired.
Program This is the main program output.
Clean Pgm This is the main program output before the DSK stage.
Preview 1Preview 1 can be switched between any source, a number of mixing points in the
system and transition previews.
Preview 2Preview 2 is a second preview output with similar capabilities to the first, except that
it cannot preview mixer transitions.
Two copies of each output are available.
The Preview 1output is also available in Analogue Component, as either YPbPr or RGB. Whether
YPbPr or RGB format is used can be selected in the Configure - System - Genlock & Outputs
menu. The R, G, B and Y outputs have syncs. If the monitor requires separate syncs, the Ref
Sync Output can be used if it is not required for system referencing.

SWITCHER TIMING FOR VTR PRE-READ
Introduction Pre-read is a facility of some VTRs which allows video
information to be read from the tape, be processed by some
external equipment and then written back to the tape in the
same place as it was read from. This process allows tape to
tape editing to be carried out using only two VTRs instead of
the normal three.
Processing delay The processing equipment will delay video passing through it
by some amount of time. This delay must be less than the
maximum delay which can be accommodated by the pre-read
VTR. Different makes and models of VTR have different
maximum delay capabilities, refer to the VTR manufacturer for
this information.
The processing delay of a Golden DaVE switcher is dependant
on how it is set-up. Absolute minimum delay is 14u sec with
no option card fitted, or 33u sec with the OPT card fitted but
with no Border Gen delay set. The maximum Border Gen
delay which can be set is 20 lines, making the maximum delay
through a Golden DaVE switcher, with no DVE, 1313u sec.
Setting Golden DaVE How Golden DaVE can be set and used depends on the delay
handling capabilities of the pre-read VTR being used. If the
VTR can accept a delay of 21 lines, or more, the full Colour
Correction, Chroma Keying and Border Generation facilities of
Golden DaVE can be used.
Note DVE cannot be used with pre-read as the delay produced
by the DVE function is one full frame.
There are two standard methods of synchronising the video
sources, switcher and VTR(s) which are shown in diagrams on
the next page, these methods are:-
a) Sync everything to studio black burst reference. In this case
the Genlock Phase of the switcher should be set to a positive
value anywhere between the actual delay of the switcher and
the maximum delay the pre-read VTR can accommodate.
b) Use the sync O/P reference of the switcher to synchronise the
sources and VTR(s). In this case the switcher sync output
Sync Phase should be set to a negative value anywhere
between the actual delay of the switcher and the maximum
delay the pre-read VTR can accommodate.
Note Ensure that the VTR(s) is/are set-up to be synchronised to the
external sync reference and not to the video on the tape!
