CHAPTER 1: In tallation
Introduction
Overview
The iAM-12G-SDI is a 2RU multichannel multi-source audio/video monitor with
multiple standard copper connections and multiple S P module options facilitating
high density coax and optical fiber connections. The iAM-12G-SDI includes dual 12G
SDI S P inputs and it can monitor 12G/3G/HD/SD-SDI video and audio from the
selected one.
An optional module allows decoding, monitoring, and metering of Dolby
®
ATMOS, E,
DD+, and D from SDI, SMPTE 2110, SMPTE 2022-6, and AES streams. or those
who do not at the present time require Dolby
®
ATMOS decoding, another optional
module is available to decode, monitor, and meter Dolby
®
E, DD+, and D from SDI,
SMPTE 2110, SMPTE 2022-6, and AES streams .
The iAM-12G-SDI has options for VoIP formats including SMPTE 2022-6,
3G/HD/SD-SDI, and a growing range of additional I/O options via S P interfaces.
Refer to the Specifications section of this manual or contact Wohler Sales for more
information.
The iAM-12G-SDI is compact and simple to operate. It has touch screen LCD
displays providing high resolution meters, menus and basic monitoring controls.
Any channel (or group of up to 16 channels that are clustered together) from any
source stream may be audibly monitored and summed with the other selected
channels to provide flexible monitoring capabilities.
Setups are created and configured using a web browser over a network connection
to the integral web server of the iAM-12G-SDI.
Each iAM-12G-SDI 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 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 outle
t for
your safety. If the plug does not fit into the outlet, contact an
electrician to replace the obsolete outlet.

Page 7
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 connects to an AC mains power source (100 to 240 VAC, 1.5A, 50/60Hz)
using a supplied IEC power cord.
When the mains plug or appliance coupler is used as the disconnect device, the
disconnect device should remain operable.
Compliance
CC
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the CC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Important
:
Heat generated by the class D power amplifiers, power supplies,
and other components is vented by slots in the sides and back of
the unit. Therefore, as a safety precaution, you must allow proper
ventilation on these surfaces.

Page 8

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, 7.1, or 10.2).
Audio meters are displayed on the touchscreen display in labeled clusters, as shown
in igure 2-8. The clusters of channels and other options relating to this are defined
using the iAM-12G-SDI Web GUI software as described in Chapter 4.
igure 2-8: Audio Level Meter Screen
1. Channel Identifier : Above the level meters are the Channel Identifiers.
They indicate the following:
An arrow pointing to the left indicates that this is a left channel and
will be monitored in the left speaker.
An arrow pointing to the right indicates that this is a right channel
and will be monitored in the right speaker.
A square indicates that this is a center channel and will be monitored
Important:
The numbers for
each
meter
bar graph
position only indicate its relative
position on the display, and not any particular channel number. Meter
numbers only serve as references for monitor configurations at the Web
GUI level.

in both speakers.
The symbol shown on channels 7 and 8 in igure 2-8 indicate that
this channel pair is a Dolby bitstream. Refer to the Dolby Zoom
section of this chapter.
If these symbols appear on a channel pair, they indicate that this
channel pair is a Dolby bitstream, but that the Dolby Decoder within
the iAM-12G-SDI is still booting up and that you may not yet select
the Dolby Zoom function on them. 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. Monitor Info: The name of the currently selected input signal source is
typically shown here for your reference, although other information may
be shown. If an SDI Source is being monitored, rotating the Left Adju t
knob will cause this display to alternate between the input signal source
and the SDI signal format, such as:
3. Main Menu: Touching the Main Menu selector proceeds to the Main
Menu. Refer to igure 2-13. The Main Menu provides a selection of
option setting and system information screens.
4. Channel / Clu ter Touch Selection Area: Touching the meters of a
cluster will let you mute, un-mute, or solo the associated channel(s).
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-12G-SDI is first
powered, 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 Right Adju t control will move a
white selection box from channel to channel. Press the Right
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 Right 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
87

Page 18
the channel. While the channel is soloed, the Monitor Info display
will show the Channel Routing, for example:
d. Channel Routing: After soloing a channel, rotating the Left
Adju t knob will allow you to reassign the Channel Routing for the
soloed channel. The range of choices is shown in Table 2-1. Make
this choice thoughtfully and carefully because it will change what
you see and hear while monitoring the audio sources from now on,
or until you change it again.

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 Right Adju t control
until the Dolby bitstream, as identified by the Dolby icon (shown here at
right), is highlighted and then press the Right 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 2-8. The Dolby 5.1 Zoom Screen is shown in igure
2-9.
Dolby D, DD+, and E decoding is an optional feature requiring either the OPT-
DOLBY the OPT-DOLBY ATMOS module. Contact Wohler Technical Service to
install software licenses.
igure 2-9: Dolby 5.1 Zoom Screen
When the Dolby Zoom screen appears, the speakers will automatically begin
monitoring the Downmix audio. However, you may solo or mute the individual
channels for troubleshooting or other purposes. Use the left screen to select other
Dolby E channels to be monitored. Touch and slide the control on the Dolby
Metadata screen to scroll through multiple lines of metadata.
Touching the Exit Dolby button returns you to the monitoring screen from which
87

Page 20
you came.
Touching the Dolby Metadata button proceeds to the screen shown in igure 2-10.
igure 2-10: Dolby Metadata Screen
Touching and moving the scroll bar at the right will let you review the list of Dolby
Metadata. Touch the Meter button to return to the Dolby Zoom screen as shown
in igure 2.9.
Dolby
®
ATMOS Screen
Dolby ATMOS decoding is an optional feature requiring the OPT-DOLBY ATMOS
module. It allows decoding of Dolby
®
ATMOS content, along with the familiar
Dolby
®
D, Dolby
®
D+, and Dolby
®
E content. Because of the increased number of
channels, up to 10.2, Dolby
®
ATMOS creates an amazing experience over speakers
and over headphones, with breathtaking, moving audio that flows above and
around you. Wohler’s Dolby ATMOS option allows broadcasters to confidence
monitor the Dolby ATMOS signal on the speakers and headphone output, view
meters, access Wohler’s proprietary Dolby Zoom functionality, review related
metadata, and route the audio externally to SDI or analog outputs on the rear
panel. A decoded Dolby 10.2 Zoom Screen is shown in igure 2-11.
Touching the Dolby Metadata button proceeds to the screen shown in igure 2-10.
Touching the Meter on that screen will return to the Dolby 10.2 Zoom screen as
shown in igure 2.11.
The Dolby Codec in use is displayed in the Monitor Info box at the top of the screen.
