•Rental/staging applications

2 VP-4x4K - Getting Started

2 Getting Started

We recommend that you:

•Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

•Review the contents of this user manual

Use Kramer high performance high resolution cables

Use only the power cord that is supplied with this machine

Go to http://www.kramerelectronics.com to check for up-to-date

user manuals, application programs, and to check if firmware

upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the best performance:

•Use only good quality connection cables to avoid interference, deterioration

in signal quality due to poor matching, and elevated noise levels (often

associated with low quality cables)

•Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

•Position your Kramer VP-4x4K away from moisture, excessive sunlight and

dust

VP-4x4K - Overview 3

3 Overview

The VP-4x4K is a true 4x4 matrix switcher for computer graphics (up to and exceeding

UXGA) signals and balanced stereo audio signals. The VP-4x4K lets you

simultaneously route any or all of the four inputs to any or all of the four outputs.

In addition, the VP-4x4K features:

•A video bandwidth of 400MHz that ensures transparent UXGA performance

•DC coupled inputs and outputs

•A selectable delayed switching mode (ranging from 0 to 3.5sec, in

increments of 0.5sec) for clean transitions (seamless switching) when

switching between non-genlocked sources

•Audio gain control for the inputs and the outputs

•Audio-follow-video and breakaway options

•Storing and recalling setup options

•A TAKE button for precise switch control that lets you execute multiple

switches all at once

•A LOCK button to prevent tampering with the front panel

•The ability to automatically detect connected input signals (the respective

button illuminates in green)

•Our innovative integrated sync processing; KRISP™ technology that lets you

achieve a sharp, stable image when the sync level is too low, by restoring

the sync signal waveform

Control the VP-4x4K using the front panel buttons, or remotely via:

•RS-485 or RS-232 serial commands transmitted by a touch screen system,

PC, or other serial controller

•The Kramer RC-IR3 infrared remote control transmitter

•The Ethernet

VP-4x4K - Overview 5

# Feature Function

1 POWER Switch Illuminated switch for turning the unit ON or OFF

2 IR Receiver Signals from the remote control transmitter illuminate

the LED

3 SELECTOR

Buttons

OUT Select the output to which the input is switched

IN Select the input to switch to the output

When a signal is detected, the input button illuminates

in green

The SELECTOR IN and OUT buttons also store/recall the

input/output configurations (see Section 6.8)

4 ALL Button Pressing ALL before pressing an input button

connects that input to all outputs

For example, press ALL and then Input button # 2 to

connect input # 2 to all the outputs

5 OFF Button Pressing OFF after pressing an output button

disconnects that output from the inputs. To disconnect

all the outputs, press the ALL button and then the OFF

button

6 AFV Button When illuminated, the audio channels follow the video

channels. The button is illuminated when the AFV

mode is selected

If the AUDIO differs from the VIDEO, the TAKE button will

flash, and you have to press the TAKE button to confirm

the modification

7 VID Button When illuminated, actions relate to video

The VID button is illuminated when in breakaway mode

and actions relate to video

8 AUD Button When illuminated, actions relate to audio

The AUD button is illuminated when in breakaway mode

and actions relate to audio

9 STO Button Pressing STO (STORE) followed by an output or an

input button stores the current setting

Press the STO and LOCK buttons simultaneously to set

the delay time (see Section 6.3)

For example, press STO and then the Output button # 3 to

store in Setup # 3

10 LOCK Button Disengages the front panel switches

11 RCL Button Pressing RCL (RECALL) followed by an output or an

input button displays a stored setup

12 TAKE Button Pressing TAKE toggles the mode between the

CONFIRM mode and the AT ONCE mode (user

confirmation per action is unnecessary). When in

CONFIRM mode, actions are confirmed by pressing

the TAKE key

For example, press STO and then the Output button # 3 to

store in Setup # 3

When in the CONFIRM mode, the TAKE button illuminates

13 AUDIO GAIN Button Press to adjust the audio input or output gain (see

Section 6.2)
