Overview

3 Overview

The VP-27 is a high quality presentation switcher designed for a wide variety

of presentation and multimedia applications. The VP-27 combines the

functions of a 4x1 switcher for composite video and audio, a 4x1 switcher for

s-Video and audio, and a 4x1 switcher for computer graphics video (PC/VGA)

type signals with audio.

The VP-27 is a one-box high-performance solution for installations that would

otherwise require several separate products, and is designed so that each

section is controllable independently from the other sections.

The VP-27 features:

An additional audio switching section that routes one of the pre-selected

audio inputs from the other switching sections to a separate output

24 selector switches and front panel control adjustment for master audio

output level and microphone level, mix, mute, and talk over

The ability to insert a microphone channel by switching, mixing, or talk-

over

A LOCK button to prevent tampering with the front panel

Control the VP-27 via the front panel buttons or IR remote control using the

Kramer infrared remote control transmitter (provided) or by RS-232 serial

commands transmitted by a touch screen system, PC, or other serial controller.

To achieve the best performance:

Connect only good quality connection cables, thus avoiding 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 and position your Kramer VP-27 away

from moisture, excessive sunlight and dust

Installing the VP-27 in a Rack

5 Installing the VP-27 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:

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.

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
