CHAPTER 1: In tallation
Introduction
Overview
The iAM-VIDEO-2 and iAM-VIDEO-2-MPEG units are 2RU multichannel multi-source
audio/video monitors with multiple standard copper connections and multiple S P
module options facilitating high density coax and optical fiber connections. The iAM-
VIDEO-2 includes a 3G SDI S P module and it can monitor both video and audio
from it. An optional module will allow decoding of Dolby D, DD+, and E streams.
The iAM-VIDEO-2-MPEG includes an MPEG module, so it accepts MPEG Video
transport streams over ASI or IP. Both products have options for VoIP formats
including MPEG2/4 TS and SMPTE 2022-6, 3G/HD/SD-SDI, and a growing range of
additional I/O options via an S P interface. Refer to the Specifications section of
this manual or contact Wohler Sales for more information.
The iAM-VIDEO is compact and simple to operate. It has touch screen LCD displays
providing high resolution meters, menus and basic monitor controls. Any channel
(or group of channels that are clustered together) from any source stream may be
audibly monitored and summed with the other selected channels.
Setups are created and configured using a web browser over a network connection
to the integral web server of the iAM-VIDEO. Setup configurations can easily be
copied to other iAM-VIDEO units.
Each iAM-VIDEO can be configured with Presets, which are complete monitoring
configurations. Very little about the configurations of those predefined setups can
be changed from the front panel. This prevents less experienced or hurried
operators from making accidental setup changes that could compromise their usage
of the unit. It also reduces operator training to a minimum.
Safety
Instructions
1. Read, keep, and follow all of these instructions; heed all warnings.
2. Do not use this equipment near water.
3. Use only a dry cloth to clean the equipment.
4. Do not block any ventilation openings.
5. Do not install near any heat source such as a radiator, heat register, amplifier, or
stove.
6. Do not attempt to plug the unit into a two-blade outlet (with only two prongs of
equal width).

Page 7
7. Protect the power cord from being walked on or pinched, particularly at plug
connection on the equipment and at the socket.
8. Use only the attachments/accessories specified by the manufacturer.
9. Unplug the equipment during lightning storms or when unused for long periods
of time.
10. Refer all servicing to qualified service personnel. Servicing will be required
under all of the following conditions:
a. The equipment has been damaged in any way, such as when the power-
supply cord or plug is damaged.
b. Liquid had been spilled or objects have fallen onto the equipment.
c. The equipment has been exposed to rain or moisture.
d. The equipment does not operate normally.
e. The equipment has been dropped.
Safety Symbols
Mounting
The unit is designed for a standard 19" rack. Install it at ear/eye level for best high
frequency response and visual observation of the display screens. Please adhere to
the following clearances:
Table 1-1: Clearance Recommendations
Clearance Surface
24” ront
3” Rear
2” Sides
1.75” Top and Bottom (if either radiates heat)
0” Top and Bottom (if no heat)
Heat Dissipation
The ambient temperature inside the mounting enclosure should not exceed 40°
Celsius (104° ahrenheit). Adjacent devices can be rack mounted (or stacked) in
WARNING:
The symbol to the left warns of electric shock hazard inside the unit.
Disconnect the power cord before removing access panels when
installing upgrades. Only qualified service personnel are to operate
the equipment with covers removed, and are to exercise caution to
avoid personal injury.
Important:
By design, this monitor will only plug into a three
-
prong outlet for
your safety. If the plug does not fit into the outlet, contact an
electrician to replace the obsolete outlet.

Page 8
proximity to the unit if this temperature is not exceeded. Otherwise, allow a 1RU
(1.75”/44.45mm) space above and below the unit for air circulation.
Sympathetic Vibration
Sympathetic vibration from other equipment (cables, etc.) in the rack may be
serious enough to interfere with the unit’s sound quality. If you experience
sympathetic vibrations, use thin card stock, felt, foam, or weather-stripping
between the vibrating surfaces. Tie loose cables securely with cable ties.
Mechanical Bracing
Both the 1RU chassis and the 2RU chassis are securely attached to the front panel.
In addition, the chassis has mounting tabs through which you attach it to the rack
rail. This feature will reduce or eliminate rear bracing requirements in many
mobile/portable applications. The weight of internal components is distributed fairly
evenly around the unit.
Electrical Interference
Be careful to avoid mismatched cable types and other similar causes of undesired
reflections in digital signal systems. If severe enough, such reflections can result in
corruption of the digital data stream. As with any audio equipment, maximum
immunity from electrical interference requires the use of shielded cable; however,
satisfactory results can sometimes be obtained without it. The internal circuitry
ground is connected to the chassis.
Power
The unit comes with a standard external 18 VDC / 3.9 A power supply that connects
to an AC mains power source (100 to 240 VAC, 1.5A, 50/60Hz) using an IEC power
cord.
When the mains plug or appliance coupler is used as the disconnect device, the
disconnect device should remain operable.

CHAPTER 2: Local Operation
Local v Remote Operation
The iAM-VIDEO can be operated locally or remotely. Locally, all of the monitoring
functions are available, as well as a limited set of programmable options, as
described in this chapter. It may be operated remotely in two ways, via the Wohler
Web GUI or by third party equipment via Application Programming Interface (API)
commands. The Wohler Web GUI is described in Chapter 4 of this manual. The API
commands are described in Appendix D of this manual.
Startup
The iAM-VIDEO unit will begin its startup process when it is connected to power
through its external power supply. There is no power switch. It is normal for the
product to require just over a minute to start up and be ready to use.
When the iAM-VIDEO unit completes its startup, the Power indicator will turn
green. Depending upon optional settings, all channel clusters will either be in the
muted condition or set in a predetermined way. You may then touch the meter
clusters on the screen to mute, unmute, or solo channel clusters as needed.
Front Panel
The front panel is shown in igure 2-1.
igure 2–1: iAM-VIDEO ront Panel
1. Speaker : Two full range speakers provide local near field audio monitoring
through the use of powerful class D amplifiers.

panel. Speaker audio mutes when headphones are plugged in.

Page 11
3. Volume: This controls the speaker and headphone output level for the entire mix.
4. Balance: This controls left/right levels for the stereo mixes. By default, it controls
loudspeaker and headphone output, though other options may be set in the Web
GUI preferences.
5. Adju t / Aux Volume: Turning this control right or left moves a light yellow
selection box from channel to channel on the metering screen. Pressing this control
solos the selected channel and surrounds its meter with a blue selection box. If a
muted channel is selected with this control, it is unmuted and soloed. Touching the
meter area anywhere or pressing the Adju t knob again removes the channel solo
and resumes the audio selections made before the channel solo operation.
6. USB 2.0 Port: This USB Type A connector allows you to use a flash drive (not
supplied) to perform software updates and copy system configurations to another
iAM-VIDEO or to a PC. Software updates are accomplished from the Web GUI.
7. Video Di play: The selected SDI or MPEG video signal is monitored on this screen.
A variety of other informational video displays can appear along with the monitored
video. This is set up using the iAM-VIDEO Web GUI interface.
8. Level Meter Di play: High resolution bar graph meters appear here showing the
levels of up to 16 channels selected for monitoring. These are grouped into clusters
as specified in the Web GUI: mono clusters (1.0), pair clusters (2.0), or surround
sound clusters (5.1 or 7.1). This screen will respond to touch control of audio Mute,
Un-Mute and Solo. Access to the Menu screens is also available on this screen. The
meter display is temporarily replaced when menu access is needed. These menus
are used for a limited amount of setup and status display. The large majority of
setup functions are performed using the Web GUI.
9. Power: This indicator lights green when the system is powered and ready for use.
A solid or blinking yellow color indicates that the product is starting up.
Rear Panel
The rear panel is shown in igure 2-2.
igure 2-2: iAM-VIDEO Rear Panel Layout

6. MADI BNC: This COAX input accepts an AES10 64-channel signal at
48kHz sample rate. The COAX output is reclocked from the MADI source.
When power to the iAM-VIDEO is not present, the COAX input and output
are automatically connected together to allow the MADI signal to pass
through.
7. MADI Fiber SFP: (optional) This input module accepts an optical AES10
64-channel MADI input signal at 48 kHz sample rate. The S P fiber
module may be used in conjunction with the MADI BNC connectors to
provide COAX to fiber or fiber to COAX conversion. The outputs are
reclocked. A software license must be installed for S P ports to function.
Refer to the System Setup section in Chapter 4 and to igure 4-13 to
install software licenses.
8. Dolby Metadata: (future implementation)
9. AES Out: By default, the AES OUT 1 BNC outputs the same mixed audio
as the XLR analog outputs, as heard from speakers or headphones, but as
an AES3id pair. This output is adjusted by the Volume control. Other
Important:
The monitor and power adapter have been tested as a combined
apparatus to verify compliance with applicable safety and
electromagnetic compliance standards. Use of another power adapter
provided by the user may negate the compliance or cause the
monitor to not perform properly. Wohler Technologies cannot accept
any responsibility for the outcome in such cases.
Important:
By design, the supplied AC mains power cord will only plug into a
three-prong grounded outlet for your safety. If the plug does not fit
into the outlet, contact an electrician to replace the obsolete outlet.

SFP-2022-6 / SFP-2110 Addre Setup
While the optional S P-2022-6 and S P-2110 modules monitor program audio
created from distinctly different technologies, both are connected to the network in
the same way and have the same requirements for addressing. igure 2-5
illustrates the network connections they need.
igure 2-5: S P-2022-6 and S P2110 Network Diagram
The optional S P-2022-6 or S P-2110 module furnished by Wohler Technologies is
manufactured by Embrionix and comes from the factory with a default IP address.
To integrate it into your digital network, you need to set its address to the source to
be monitored. You must use the emSET configuration software to set up this option.
It is available from Wohler Technologies Technical Service. The procedure to
accomplish this is described in the SFP-2022-6 / SFP-2110 Setup Guide (part
number 821822), which is available at https://www.wohler.com/wp-

Channel Meter and Touch Operation
The audio mixer terminology of “solo” is used in this manual when referring to
muting all but a specific audio channel or subgroup. Since the terms “group” and
“subgroup” have different meanings in SDI vs. pro audio, this manual uses the term
“cluster” to define a set of audio channels forming an audio program—such as Mono
(1.0), Stereo (2.0) or Surround (5.1 or 7.1).
Audio meters are displayed on the touchscreen display in labeled clusters, as shown
in igure 2-6. The clusters of channels and other options relating to this are defined
using the iAM-VIDEO Web GUI software as described in Chapter 4.

The symbol shown on channels 7 and 8 in igure 2-6 indicate that
this channel pair is a Dolby bitstream. Refer to the Dolby Zoom
section of this chapter.
The channel numbers within the symbols indicate the numbered position
in the meter display, not the channel position within the monitored
stream. Channel assignment is made in the Configure Pre et page of
the Web GUI.
2. Monitored Input: The name of the input signal source that is currently
selected appears here for your reference.
3. MPEG Analyzer: The MPEG Analyzer selector only appears while
monitoring MPEG signals that were selected using the Source Select

Colored boxes surrounding the cluster or channel indicate what operation
is being performed. The following describes each function:
a. Mute / Un-Mute Selection: A violet box surrounds any channel
cluster that is muted. Typically, when the iAM-VIDEO is first
powered or when a preset is changed, all of the channel clusters
are muted. Touching a muted channel cluster un-mutes it and
removes the violet box. Muting and un-muting by touching is an
alternate action function.
b. Solo Selector: Touch for two seconds any channel cluster you
would like to solo. A blue box will then surround the cluster and
that will be the only cluster you hear. Any violet boxes will
disappear. Touch again to return the combination of monitored
clusters to the way they were before you soloed the cluster.
c. Channel Solo: Rotating the Adju t control will move a white
selection box from channel to channel. Press the Adju t control to
solo the selected channel. That channel alone will then be
surrounded by a blue box and it will the only channel being
monitored. Press the Adju t control again or touch anywhere on
the meters to undo the solo and return the combination of
monitored clusters to as it was before you soloed the channel.

Dolby Monitoring Screen
Dolby Zoom Screen
Dolby Zoom is a very powerful analysis tool. Much as a camera lens can "zoom"
into a single subject of interest out of many, the Dolby Zoom feature lets you
quickly "zoom" into a single Dolby bitstream, out of multiple encoded Dolby
streams and other channels. Simply rotate the Adju t control until the
Dolby bitstream, as identified by the Dolby icon (shown here at right), is
highlighted and then press the Adju t control. You can immediately
listen to and meter the contained audio channels, as well as view the Dolby
metadata. Bitstreams are shown distinctively along with the normal metering
channels, as shown in igure 2-6. The Dolby Zoom Screen is shown in igure 2-7.
Note: The Dolby Zoom feature functions only for Dolby audio carried over
traditional signals. It is not available for Dolby audio carried over MPEG.
Dolby decoding is an optional feature requiring the OPT-DOLBY module. It
allows decoding and monitoring of Dolby® D, DD+, & E streams. Refer to the
Sy tem Setup section in Chapter 4 and to igure 4-13 to install software licenses.
igure 2-7: Dolby Zoom Screen
