•Looping inputs
•Selectable input signal termination
•A TAKE button1
•Two sets of INPUT SELECTOR buttons (one set for each output) and
five front panel control buttons
for precise switch control and a LOCK button to prevent
tampering with the front panel
•Audio-follow-video or audio breakaway option
•Glitch-free transitions, when sources share a common reference sync2
•Switching synchronization either to an external reference or the incoming
video
•Two duplicate3
•Control via the front panel buttons; remotely by RS-485 or RS-232 serial
commands transmitted by a touch screen system, PC, or other serial
controller; and/or via contact closure switches
outputs per set of INPUT SELECTOR buttons (4 outputs
in total)
•Standard 1U 19” rack mount size, with rack "ears" included
To achieve the best performance:

5 Installing in a Rack
This section describes what to do before installing in a rack and how to rack
mount.
Before Installing in a Rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range: To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
•In some models, the front panel
may feature built-in rack ears
•Detachable rack ears can be
removed for desktop use
•Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
•If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)
Operating temperature range +5°to +45°C (41°to 113°F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20°to +70°C (-4°to 158°F)
Storage humidity range 5 to 95% RHL, non-condensing
!
CAUTION
!!
When installing in a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.
