Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
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.
Go to www.kramerav.com/downloads/VS-88H2 to check for up-to-date user manuals, application
programs, and to check if firmware upgrades are available (where appropriate).
Achieving Best Performance
•Use only good quality connection cables (we recommend Kramer high-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (often associated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interference from neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer VS-88H2 away from moisture, excessive sunlight and dust.
Caution:
•This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
•For products with relay terminals and GPI\O ports, please refer to the permitted rating
for an external connection, located next to the terminal or in the User Manual.
•There are no operator serviceable parts inside the unit.
Warning:
•Use only the power cord that is supplied with the unit.
•Disconnect the power and unplug the unit from the wall before installing.
•Do not open the unit. High voltages can cause electrical shock! Servicing by qualified
personnel only.
•To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which is located on the bottom of the unit.

Connecting VS-88H2
Although this user manual describes the VS-88H2 only, it applies also to VS-66H2,
VS-84H2 and VS-48H2 except for the number of inputs and outputs per device.
Always switch off the power to each device before connecting it to your VS-88H2. After
connecting your VS-88H2, connect its power and then switch on the power to each device.
Although this connecting example shows only several inputs and outputs that are
connected, you can connect all the inputs and outputs simultaneously.
To connect the VS-88H2 as illustrated in the example in Figure 9, do the following:
1. Connect up to eight video sources to the INPUT HDMI Connector (from INPUT1 to
INPUT 8). For example, connect:
▪Laptops to INPUT 1, 3, 4 and 8 HDMI connectors.
▪Blu-ray players to the INPUT 2 and INPUT 6 HDMI connectors.
2. Connect the eight video OUTPUT HDMI Connectors (from OUTPUT 1 to OUTPUT 8)
to up to eight acceptors. For example, connect:
▪OUTPUT 1, 6 and 8 connectors to projectors.
▪OUTPUT 2, 4, 5 and 7 connectors to OLED displays.
3. Connect the power cord.
We recommend that you use only the power cord that is supplied with this machine.
4. If required, connect:
▪The 5V/2A USB Port to the USB port of another device to charge it.
▪The ETHERNET RJ-45 Port to a control device.

Routing an Audio Input to HDMI Output
The D-AUDIO Button button on the VS-88H2 front panel enables to route the HDMI
embedded audio input signals to the HDMI outputs .
Generally, digital audio routing is enabled by pressing D-AUDIO. When the button is
illuminated, the embedded audio on the HDMI input is the selected audio source.
To switch an HDMI audio input to an output:
1. Press D-AUDIO .
The button illuminates (HDMI audio input to HDMI output mode) and the 7-segment LED
Display shows the current IN-OUT digital audio status.
On the front panel buttons:
•An illuminated input button means that an active digital audio signal is detected on
that input that supports LPCM audio.
•A dark input button means that there is no active digital audio source on that input
(or that the source is DVI).
•A flashing input button means that a Dolby digital audio, Dolby-TrueHD audio, or
AC-3 audio signal from a DVD player is detected on that input.
•An illuminated output button means that a display that supports LPCM audio is
connected to that output.
•A dark button means either that the display that is connected does not support audio
or that a display is not connected at all.
•A flashing output button means that a display is connected that supports LPCM,
Dolby digital, AC-3 and NLPCM audio.
On the 7-segment display:
•“0” under an output number indicates that the audio output is muted.
•“.” under an output number indicates that the HDMI output port is in ARC mode.
•Any digit shows the HDMI audio input switching state.
2. While D-AUDIO is on, select an output button (for example, 6) and then an input button
(for example, 5). HDMI audio INPUT 5 is routed to HDMI audio OUTPUT 6 and on the
7-segment display, INPUT 5 appears under OUTPUT 6.
When switching you can also press:
•An output button (1 to 8) and then OUT (MUTE) to mute the selected output
(turns 0 on the 7-segment display).
•ALL (instead of an output button) and then an input button to route the selected input
to all the outputs.
All the 7-segment display LEDs flash and then display the selected input.

Operating in ARC Mode
In ARC mode you can route the audio signal of the connected output to an input that is
connected to an audio system (for example, home theater receiver).
Ensure that the acceptor on the output side has ARC capabilities (follow the manufacturer’s
instructions).
ARC (Audio Return Channel) can be set via the front panel buttons and the embedded
webpages.
You can enable the input to accept the audio output signal, by ARC-enabling the outputs on
the device via the embedded web pages (see Switching Audio in Breakaway Mode on
page 38 for further reference). You can then route the audio output to the input either via the
embedded web pages (see Switching ARC to an Input on page 39) or via the front panel
buttons.
The following examples show how the output 6 ARC audio signal is routed to input 3, as
illustrated in Figure 14:
Figure 14: ARC Audio Routing Example
To route the audio signal from the output to the input via the front panel buttons:
1. Press the ARC button.
The ARC button illuminates, and the device enters ARC mode.
On the front panel, an ARC enabled input button:
•Flashes when that input is set to ARC mode.
•Illuminates when that button is not in ARC mode (and is set to Step-in mode).

The corresponding 7-segment display LED flashes.
3. Press an illuminated OUT (MUTE) Button (for example, output 6).
The flashing 7-segment display LED shows the selected input number and after
selecting the HDMI audio OUT the port number appears (6).
On the 7-segment display:
•“.” under an output number (when in D-AUDIO mode) indicates that arc is enabled on
the corresponding output (outputs 1 and 6 to 8 in this example).
•“0” under an output number indicates that the audio output is muted.
The HDMI OUT 6 ARC audio signal is routed to ARC input 3.
Exit ARC mode by pressing D-AUDIO or VIDEO buttons.
Muting/Unmuting an Output Audio Signal
You can mute/unmute an audio signal and a video signal separately.
To mute/unmute an audio signal:
