CHAPTER 1: Installation

Introduction

Overview

The iVAM1-3 is a 1RU multichannel multi-source audio/video monitor with basic 3G­SDI and analog inputs. It may also be purchased with a large variety of other
inputs or these may be added later at the need arises. Refer to the Specifications
section of this manual or contact Wohler Sales for more information.

The iVAM1-3 is compact and simple to operate, with straightforward controls. It has
a touch screen LCD display providing either video or high resolution level meters,
and in addition has an HDMI output. Any channels (or channel pairs) from any
audio/video source stream may be monitored. Either 8 or 16 channel meters can be
displayed.

The iVAM1-3 includes two 3G SDI inputs and it can monitor both video and audio
from them. Optional modules will allow decoding of an additional SDI input, MADI,
AES3, Dolby D, DD+, E, SMPTE 2110, SMPTE 2022-6, and AES streams. It contains
APIs for remote management.

Setups are created and configured using local menus and a web browser over a
network connection to the integral web server of the iVAM1-3. The web server will
also allow you to view the audio meters remotely.

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

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

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

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

Heat Dissipation

The ambient temperature inside the mounting enclosure should not exceed 40°
Celsius (104° Fahrenheit). Adjacent devices can be rack mounted (or stacked) in
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.

Surface

24” Front

3” Rear
2” Sides

1.75” Top and Bottom (if either radiates heat)
0” Top and Bottom (if no heat)

Important

iVAM1-3

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

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

The 1RU chassis is 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, 65W, 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.

Compliance

FCC

This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC 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.
Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at
their own expense.

iVAM-1 with SFP-2022-6 / SFP-2110

The optional SFP-2022-6 or SFP-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 MN-Set 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://wohler.com/downloads/ .

The symbol shown on channels 7 and 8 in Figure 2-8 indicates

87

that this channel pair is a Dolby bitstream. Refer to the Dolby

Zoom section of this chapter.

2. Loudness Cluster Marker: This orange bracket marks which cluster is
currently being measured for Loudness.

3. Loudness Reading: This control displays the Loudness of the selected
Cluster. It can also be touched to change which Cluster is being
measured. To do this, touch the green Loudness Reading control. It will
temporarily turn orange. You may then touch the meters in any other
cluster. The Loudness Cluster Marker will then move to that cluster and

iVAM1-3

Page 18

its measurement will begin and be displayed. You may then touch the
control again to return it to its green color, restoring normal touch
functioning, or wait 15 seconds for it to time out.

4. Channel/Cluster/Loudness Selection Area: Touching the meters of
any channel pair will let you mute, un-mute, or solo the associated
channel(s). Colored boxes surrounding the channel pair or channel
indicate what operation is being performed. The following describes each
function:

a. Mute / Un-Mute Selection: A violet box surrounds any channel

pair that is muted. Typically, when the iVAM1-3 is first powered, all
of the channel pairs are muted. Touching a muted channel pair un­mutes 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 pair you would

like to solo. A blue box will then surround the pair and that will be
the only pair you hear. Any violet boxes will disappear. Touching
another channel pair will then move the blue box to it, and it will be
soloed. Touch again to return the combination of monitored channel
pairs to the way they were before you soloed the pair.

c. Channel Solo: Rotating the Channel control will move a white

selection box from channel to channel. Press the Channel control
to solo the selected channel. That channel alone will then be
surrounded by a blue box and it will become the only channel being
monitored. Press the Channel control again or touch anywhere on
the meters to undo the solo and return the combination of
monitored channel pairs to as it was before you soloed the channel.

5. Channel Gain and Speaker Assignment: The channel gain and speaker
assignment of a particular channel can be changed dynamically from the
Front Panel controls. When a channel is soloed (as in the Solo Selector
paragraph above) the Source/Preset knob can be used to perform the
following operations:

a. Adjust Channel Gain: The user can rotate the Source/Preset

knob to adjust the channel gain for the soloed channel. This affects
the input channel gain. Valid range is from -60 to 12 dB. The

selected gain will display at the top of the screen:
Changing channel gain affects all the outputs that have “Volume
Control” enabled.

b. Channel Assignment Change: Press the Source/Preset knob

once to toggle to Channel Assignment Change mode. In this
mode, rotating the Source/Preset knob changes the speaker that
the channel is assigned to. The valid assignments are: Left, Right,
Center, LFE, Left Surround, Right Surround, Back Surround Left,
Back Surround Right, Mono Surround. The selected assignment will

appear at the top of the screen: This assignment

iVAM1-3

only affects the internal speakers and no other outputs.

Page 19

Note: In Solo mode, the Source/Preset knob cannot be used to

change the source. The changes made to the channel gains and/or
speaker assignments are temporary and revert to the original values
when a Source Select or Preset Recall operation is performed.

6. Phase Indicators: At the bottom of each channel pair is a Phase
Indicator. The indicators light a dull green if the channels in the pair are
in phase or bright red if they are out of phase. Set which Phase Indicators
appear using the Phase Config Menu or with the System Preferences:

Phase Indicator Configuration tab in the Wohler Web GUI.

Video Screen

Information about the signal can be superimposed over the upper part of the video
image. The Video Info selection in the Unit Config Menu determines whether this
information is always displayed, never displayed, or is only displayed for the first 5
or 10 seconds after switching to the video screen. Figure 2-9 shows the Video
Screen.

Figure 2-9: Video Screen

1. Video Source: This box displays the input source of the video signal.

2. Video Signal: This box displays the resolution and frame rate of the
video signal. A large variety of signals are detected, including HDR.

Note: If the Video Source and Video Signal displays have been optioned
to disappear after 5 or 10 seconds and you wish them to reappear, simply
touch the video 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. 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 Figure 2-8.
Examples of Dolby Zoom screens are shown in Figure 2-10.

Dolby decoding is an optional feature requiring the OPT-DOLBY module. It
allows decoding and monitoring of Dolby® D, DD+, & E streams.

various characteristics of the monitored audio as heard on the iVAM1-3. This screen
is shown in Figure 2-24.

Figure 2-24: Speaker Options Screen

The controls function as follows:

1. Volume Reference: The Volume Reference setting controls the
attenuation level of the internal speakers. The value ranges from 0 to -255
dB. 0 results in full volume and -255 causes the speakers to be muted.

2. Treble: This tone control adjusts the high frequency speaker audio response
from -12 dB to +12 dB. Lowering Treble compensates for high frequency
pre-emphasis or removes sibilance effects. Increasing Treble will add
“sizzle” to the sound and bring high-pitched sounds out of the mix. The
control can be touched and moved left or right to adjust in 2 dB increments.
After touching the Treble control, the Channel knob can also be turned to
make the adjustment.

3. Bass: This tone control adjusts the low frequency speaker audio response
from -12 dB to +12 dB. Lowering Bass will unmask midrange band sounds,
while increasing Bass will make the sound “fatter”. The control can be
touched and moved left or right to adjust in 2 dB increments. After touching
the Bass control, the Channel knob can also be turned to make the
adjustment.

4. Set to Flat: Touching this button will set the Treble and Bass controls to
their midpoint, resulting in a flat response with 0 dB increase or decrease in
treble and bass response.

receive a phase meter on the Metering Screen. Generally, it is useful to
monitor the relative phase of stereo pairs. However, sometimes each
channel of a pair is unrelated to each other. This can be because the
channels are used to convey two independent monophonic signals or that
one channel may be a Center channel and the other may be a Low Frequency
Effects channel. In these instances, the Phase Indicator would almost always
indicate an out of phase condition. Because this would be a needless
distraction to the operator, switches are provided on this screen to
individually turn phase monitoring for each channel pair on or off.

HDMI Settings

Touching the HDMI Settings selection on the Main Menu proceeds to the HDMI
Settings menu, as shown in Figure 2-29.

Figure 2-29: HDMI Settings Menu

The controls in this menu function as follows:

1. HDMI Display: Set to On or Off to enable or disable the HDMI Output on
the rear panel. The HDMI Output will allow you to view the monitored video
on an external HDMI monitor.

2. Use EDID: HDMI monitors can produce Extended Display Identification Data
(EDID) to disclose their capabilities to the video source. The iVAM1-3 can use
this information to ensure its compatibility with the HDMI Monitor. If you
decide that you do not want the iVAM1-3 to receive this information, set this
switch to Off. By default this switch is set to On.

3. Pixel Format: This selection can only be adjusted if the Use EDID setting is
set to Off. The possible choices are:

a. RGB

b. YCbCr444

c. YCbCr422

4. Save & Exit: When you have finished making the changes you want on this
screen, touch the Save & Exit button to save the changes and return to the

function is about to make to the product, it asks for you for verification that you
really want to proceed.

The Factory Reset function should be used with caution. It deletes all of the
settings you have programmed into the system. It returns the system to the way it

was when received new from the factory. After using this function, you will need to
use the Wohler Web GUI to reprogram everything from the start.

Figure 2-37: Factory Reset

Note: Factory Reset will also reset your IP address to the default one. After a

Factory Reset, the IP Settings will need to be updated. The default IP address for
the unit is determined based upon the Mac address. It is 169.254.1.xx where xx is
the last octet of the management Mac address. For example, if the Mac address is
b4:ed:54:d0:04:28 then the IP address would be 169.254.1.40 (40 is the decimal
equivalent for the last octet of Mac address 28.)

CHAPTER 4: The iVAM1-3 Web GUI

The self-contained iVAM1-3 Web GUI allows you to customize the configuration of
the iVAM1-3 to suit your needs. If the default configuration suits your needs and
you prefer to use it that way, then you do not need to use the iVAM1-3 Web GUI.

The iVAM1-3 Web GUI also allows you to have a remote view of the Meter Screen.
Refer to the Audio Meters section in this chapter.

Web Browser / Control Device

Any web browser application running on any networked device such as desktop or
laptop computer, tablet or smart phone can be used with the iVAM1-3 Web GUI.

Tablets with no network connector need to be linked to a copper LAN through a Wi­Fi adapter.

Although they can be used, smart phones are not recommended because their
smaller screen size would require more scrolling, making operation challenging.

The Chrome® web browser is recommended for speed and compatibility.

First Time IP Assignments

The iVAM1-3 can operate with a static (fixed) or dynamic (DHCP) IPv4 address. The
default address will be 169.254.1.x where x depends upon the MAC address of the
unit, when received from the factory or when switched from DHCP to static
addressing mode. There two basic types of connections that may be used to
connect the iVAM1-3 to a web browser, a Peer-to-Peer Connection or a Network
Connection.

Peer-to-Peer Connection

The most straightforward way to connect the iVAM1-3 to a web browser, free of
possible network conflicts, is to establish a static peer-to-peer connection between
the setup computer and the iVAM1-3. A 10/100/1000 MHz Ethernet switch may be
used in between, but is not required.

Figure 4-1 shows an example of suitable address settings for the host computer in
a Windows control panel. For Peer-to-Peer the IP address of windows should be in

169.254.1.x domain.

iVAM1-3

Page 54

Figure 4–1: Host IP Settings

Close the control panel and reboot the host computer after making an IP address
change to be sure the change takes effect. Either reconnect to the installed network

or continue with this direct connection to access the iVAM1-3 Web GUI.

Network Connection

When connected to a network, the iVAM1-3 address will need to be changed to
another address in order to be compatible with the address assignments for that
particular network. Immediately after the host setup is complete, change the
iVAM1-3’s address. Make the corresponding address, mask and gateway changes in
the iVAM1-3 Network Setup page. Refer to the Network Setup section which
follows.

Otherwise set the iVAM1-3 to DHCP address mode by checking the box for ‘Use
DHCP?’ in Network Setup and have your IT administrator assign rights and settings
for operation on the network. Allow enough time for your network’s DHCP server to
recognize a new network device and assign an address after booting.

The iVAM1-3 uses link local addressing for its internal network, so no
accommodation for this need be made in the network.

iVAM1-3

Page 55

Network Setup

Make network IP Address changes for the local iVAM1-3 Management (MGMT)
Port here.

iVAM1-3

Figure 4–2: Set IP Addresses

The procedure for changing the IP Address information is as follows:

1. Use DHCP? Check this box if your network has a DHCP server and you want
to use dynamic addressing. Otherwise, you must enter static IP address
entries in the four fields which follow.

2. IP Address: Enter the network address. Leading zeroes are not required.

3. IP Mask: This should usually be 255.255.255.0 unless your network can
work across multiple subnets.

4. Gateway Address: This should usually be the same domain and subnet
address numbers as the IP Address, but with the last octet being .1.

5. DNS-nameserver: A default value is shown for reference only. DNS is not
normally required for basic static IP network configurations to work. Your IT
administrator will specify a value to work with mixed static/dynamic network
setups.

6. Apply: When you have made all of the necessary entries, press Apply to
apply the changes.

7. Reset: If you should start to make changes and then change your mind
about making them, press Reset to return the settings back to where they
were.

Dashboard

Throughout the Web GUI, pages are a click or two away using the list of selections
on the left side. The Dashboard page shows all of the available Preset
configurations at a glance. The iVAM1-3 allows you to assign Presets to particular
groups. In Figure 4-3, two groups, Operator-1 and Operator-2 are shown.

In Figure 4-4, it can be seen that there are five Presets in the Operator-1 group and
no Presets in the Operator-2 group. The currently selected active Preset for local
operation is shown in red. In Figure 4-4, this is the Preset named SDI-1.

Figure 4–4: Dashboard Preset Recall / Edit

A Group / Preset Summary is shown in the upper right of the screen. This enables
you to see the total number of Groups, Presets and Favorite Presets in the iVAM1-3.

Use the button, as shown in Figure 4-4, to toggle between Favorite Presets or
All Presets.

Click the Recall button to recall a Preset. To Edit a Preset, click the Edit icon, as
shown in Figure 4-4, to the right of the associated Recall button.

After clicking the Preset Edit button, the screen shown in Figure 4-5 will appear.
Clicking a Group Edit button will cause the screen in Figure 4-6 to appear.

These are as shown in Figures 4-8, 4-9, 4-10, and 4-11.

System Audio Clock Reference Tab

The System Audio Clock Reference setting provides a way to set the global clock
source for the unit. This setting will be used whenever a source is selected using
the Source Select knob or the Source Select Menu. If the System Audio Clock
Reference is set to None, then the currently selected source acts as the Clock
Reference. This tab is shown in Figure 4-8.

This System Audio Clock Reference setting can be overridden by the optional
System Clock Reference setting in the Preset Management menu when the Preset is
chosen.

Loudness Configuration Tab

The Loudness Configuration tab allows you to make settings which will determine
how Loudness is to be calculated on the Loudness Meter. This tab is shown in
Figure 4-9.

Figure 4–9: Loudness Configuration Tab

iVAM1-3

The following settings can be made on this tab:

1. Loudness Standard: This is the loudness standard by which the loudness
calculation is made.

2. Reference Level: This is the set point in the loudness measurement about
which the determination is made as to whether an alarm should be displayed.

3. LRA Window: This is a moving window of time over which the loudness
measurement is made.

4. Default Cluster: When a Metering Screen is entered, this is the number of
the cluster that will initially be monitored for Loudness.

5. Alarm:

a. Over: The Alarm indication will only appear when Loudness has

exceeded the Reference Level by the Tolerance amount.

b. Under: The Alarm indication will only appear when Loudness is below

the Reference Level by the Tolerance amount.

c. Both: The Alarm indication will only appear when Loudness has

exceeded or is below the Reference Level by the Tolerance amount.

d. Off: The Alarm indication will not appear.

6. Alarm Tolerance: This is the range over which a normal loudness indication
is given. Above or below this range will result in color changes in the graph.

7. Loudness Window: This may be set to Momentary, Short, or one of 22
values, ranging from one second to two hours.

8. Monitoring Mode:

iVAM1-3

Page 63

a. Manual: Touch the Manual button to enable Manual Mode. This allows

you to measure the loudness of a specific program or segment of a
program, such as a commercial. In this mode, the Start and Stop
button on the Loudness Meter screen can be manually used to begin
and end a loudness measurement interval. The reading for that
interval is then held on the Loudness Meter.

b. Continuous: Touch the Continuous button to enable Continuous

Mode. In this mode, loudness readings are continually made. The Stop
button on the Loudness Meter screen is not active.

Note: Further and more detailed descriptions of all of the above Loudness terms
may be found in the ITU-R BS.1770-3 loudness standard.

When you have finished making the settings click Apply to save them or click
Cancel to discard them.

Phase Indicator Configuration Tab

The Phase Indicator Configuration tab is as shown in Figure 4-10. It allows you to
select which channel pairs will receive a phase meter on the Metering Screen.
Generally, it is useful to monitor the relative phase of stereo pairs. However,
sometimes each channel of a pair is unrelated to each other. This can be because
the channels are used to convey two independent monophonic signals or that one
channel may be a Center channel and the other may be a Low Frequency Effects
channel. In these instances, the Phase Indicator would almost always indicate an
out of phase condition. Because this would be a needless distraction to the
operator, switches are provided on this tab to individually turn phase monitoring for
each channel pair on or off. Select All and Reset All buttons are also provided.

Preset Management

Presets are monitoring configurations that can be composed of channels from
multiple sources and displayed on the meters in any order. Presets should be set up
to allow operators to quickly shift between setups for monitoring. The Preset
Management screen contains selections of all of the details for a Preset, and is
largely arranged in a matrix format connecting input channels to monitoring
channels. The screen is shown in Figure 4-15.

Preset Input/Output Matrix:

Preset Input Routing

• To create a new Preset, enter the name for the new Preset in the

iVAM1-3

Page 67

field to the left of the word Preset. Then make all of the settings
needed and save it.

• To make changes to an existing Preset, select it from the pull
down list, make the needed changes and save it.

• To create a new Preset starting with an existing Preset, first
select the existing Preset from the pull down list. Next, enter the name
for the new Preset and save it. Then make the needed changes and
save it.

Presets may be created for any licensed inputs, even if the SFP module for an
input is not plugged into its respective socket at the time. This makes it easy
to swap SFP input modules without having to recreate presets after the
insertion or removal of an SFP module. Note that if a licensed SFP module is
not detected, such as when one is removed to be swapped, its monitoring
inputs will be muted. Likewise, if the required license has not been entered
for an SFP module that is inserted, its monitoring inputs will also be muted.
Refer to the Licenses section in this chapter to install software licenses.

2. System Clock Reference: There must be a system clock reference for
monitoring to take place. Select a reference from the pull down list. The best
choice is a stable, always present clock source locked to house sync. Second
to that, use the selected input as the clock. Generally speaking, Internal is
not the best choice.

3. Speaker Delay: If desired, an audio delay may be inserted ahead of the
monitor speakers. This delay may range from 0 to 170 mS. Typically, delay is
used to align the monitored audio with a video monitored signal.

4. Input Selection: Audio from any of the input sources may be applied to the
monitoring scheme in any way. For example, you may have 6 channels from
an SDI stream, along with 2 AES channels, and along with 2 analog channels
assigned your choice of meters. A Preset Input/Output Matrix is provided
on the lower right side of the screen to allow you to assign each channel.
Simply select each input source, one at a time, and then check the boxes in
the Matrix to apply each input channel number to a metered channel
number. They do not have to be applied in any specific order. The order of
assignment should be chosen to make it easy for the operator to understand.
If there are more than 16 channels in a source, the desired group of 16 can
also be selected from the box in the lower left of the screen.

5. Autofill Selection: If you simply want to map all 16 input channels to all 16
meters in the same order, click the Autofill button. The Preset
Input/Output Matrix will automatically fill out. To remove all mapping,
click the Reset button that is adjacent to the Autofill button.

6. Cluster Definition and Naming: Channel Clusters are a series of channels
that are all associated with monitoring the same signal. For example, a
Stereo Cluster consists of two channels that together monitor a stereo signal.
A Surround 5.1 Cluster consists of 6 channels that together monitor a 5.1
surround sound signal. Clicking a Cluster Info box opens a Cluster
selection box.

In the Cluster box, you can select the type of Cluster from a pull down
selection. The available Cluster Type selections are:

• Mono 1.0: The channel will appear within a single-channel cluster.

iVAM1-3

Page 68

• Stereo 2.0: The channels will appear within a two-channel cluster.

• Surround 5.1: The channels will appear within a 6-channel cluster.

• Surround 7.1: The channels will appear within an 8-channel cluster.

• Custom: You may define a 0 to 8 channel cluster.

Multichannel clusters will expand to the right and overwrite any clusters on
overlapping meter positions.

By default, all odd numbered channels will map to the left speakers and all
even numbered channels will map to the right speakers. You may change this
using the crosspoint selections in the Input/Output Matrix.

A default name will be chosen and it will appear on the metering screen. You
may name the Cluster anything you want by simply changing the words
within the Cluster Name field.

When finished, click Update. To undo your change, click Reset. To undo all
of the Cluster changes for the 16 channels, click Reset All.

7. Speaker Assign: Speaker assignments are made automatically when a
cluster is set. However, it can be that in an actual signal, the channel
assignments may be different than what the automatic assignment assumes.
A speaker assignment adjustment is provided for each channel, should you
need to override the automatic settings. It is important to accurately assign

the function of each channel so that the Loudness calculations will be
accurate. Clicking a Speaker Assign button on a channel opens a box that

lets you change the current setting.

8. Mute/Unmute: A Mute/Unmute control is provided for each channel,
although the adjustment will affect all channels in the Cluster. This allows the
operator to just see the meters for certain channels and not hear the audio.
This is an alternate action control.

9. The Global Phase Indicators tab is as shown in Figure 4-16. It allows you
to select which channel pairs will receive a phase meter on the Metering
Screen in this Preset. Generally, it is useful to monitor the relative phase of
stereo pairs. However, sometimes each channel of a pair is unrelated to
each other. This can be because the channels are used to convey two
independent monophonic signals or that one channel may be a Center
channel and the other may be a Low Frequency Effects channel. In these
instances, the Phase Indicator would almost always indicate an out of phase
condition. Because this would be a needless distraction to the operator,
switches are provided on this tab to individually turn phase monitoring for
each channel pair on or off. By default, the settings for a Preset are the same
as the system-wide configuration set on the System Preference tab.
However, to make unique settings for this Preset, uncheck Apply Global
Phase Indicator Settings and then simply click each switch to the desired
on or off position. Select All and Reset All buttons are also provided.

10. The Output Routing tab is shown in Figure 4-17 when the OPT-OUTPUT­ROUTING capability was not purchased and licensed. This tab shows how
signals from the inputs are routed to the outputs. It allows you to view, but
not change this default routing.

Figure 4-17: Default Output Routing

However, if the OPT-OUTPUT-ROUTING license is installed, this tab allows
you to determine exactly which input channels are routed to which outputs.
It then appears as shown in Figure 4-18. This very flexible capability allows
you to route signals according to Preset or as a default for the whole system.
Refer to the Global Output Routing section in this chapter to learn the

iVAM1-3

function of each of the checkboxes and of the matrix in this tab.

To set up a different input to output routing scheme for the Preset you are
creating, click the Global Output Routing tab and uncheck the Apply
Global Output Routing checkbox. You may then adjust the output routing
as you desire on this tab and it will only apply to this Preset.

Dolby Presets

Dolby Presets are useful for customers who want to simultaneously monitor both
Dolby decoded channels and other inputs or want to have an auto-zoom to monitor
a certain pair that is known to be carrying Dolby encoded audio.

Creating a Dolby Preset is in many ways very similar to creating any other Preset.
Refer to the Preset Input Routing section of this chapter. Figure 4-19 shows a
Dolby Preset being created.

Figure 4-19: Creating a Dolby Preset

After clicking Preset Management in the list on the left, and selecting or creating
a Group name and Preset name, as shown in Figure 4-19, use the following steps to
set up a Dolby Preset:

channels should appear on which meters. To automatically fill out this matrix,
mapping channels 1 - 16 to meters 1 - 16, simply click the Autofill button.
Note that by default, channels 15 and 16 are a downmix of the decoded
Dolby channels.

Page 72

Output Routing

The Output Routing licensed feature (OPT-OUTPUT-ROUTING) allows channels to
be routed or combined and routed in custom ways to various destination outputs.
Output Routing is applied to:

1. Signals monitored using "Input Source select" from the Front Panel,

2. Presets that have been created to apply the Output Routing.

Any change to the routing will affect the Presets that have "Apply Output Routing"
selected. For example, multiple channels of a 7.1 channel program can be
combined and directed to the left or right internal speakers. Six or eight channels
could be directed to the AES outputs, which could feed an external surround sound
system. Contact Wohler Sales to purchase the license for the OPT-OUTPUT­ROUTING feature.

If Output Routing is not licensed, then any of the inputs can be monitored in
stereo or mono only through the internal speakers. The headphone jack, the analog
XLR outputs, and the first AES output will follow whatever is directed to the
speakers.

When licensed, select Global Output Routing under Configuration. This will
display the Global Output Routing screen. This screen contains a matrix of
checkboxes which are an easy way for you to set up the wide variety of input to
output routing and mixing capabilities. The Global Output Routing screen is
shown in Figure 4-20.

Destination Outputs

On the left of the Global Output Routing screen are listed the Destination
Outputs. These are the outputs to which any input can be routed. They are as
follows:

1. Speaker/Headphone: Selected inputs will be sent to the left and right
speakers. The default routing is set as per the Speaker Assignment, left
channels are sent to the left speaker and right channels are sent to Right
speaker.

2. Analog XLR: Selected inputs will be mixed to the left and right channels and
played through the two Analog XLR Outputs.

3. AES/Pair-1: Selected inputs will be mixed to the left and right channels and
played through the AES Pair 1 Output.

4. AES/Pair-2: Selected inputs will be mixed to the left and right channels and
played through the AES Pair 2 Output.

5. AES/Pair-3: Selected inputs will be mixed to the left and right channels and
played through the AES Pair 3 Output.

6. AES/Pair-4: Selected inputs will be mixed to the left and right channels and
played through the AES Pair 4 Output. The four AES outputs can be used
together to output, for example, 5.1 or 7.1 surround channels to an external
surround sound monitor system.

7. AoIP/Pair-9 (DANTE / RAVENNA): Selected inputs will be mixed to AoIP
transmit channels 59 and 60. Note that configuration for channels 1 - 58 is
not supported. Use a Dante Controller or Coveloz web interface to route
these channels appropriately.

8. AoIP/Pair-10 (DANTE / RAVENNA): Selected inputs will be mixed to
Channel 61 and Channel 62. Again, use a Dante Controller or Coveloz web
interface to route the remaining pairs appropriately.

9. HDMI/Pair-1: Selected inputs will be mixed to the left and right channels
and played through first pair of the HDMI Output.

10. HDMI/Pair-2: Selected inputs will be mixed to the left and right channels
and played through second pair of the HDMI Output.

11. HDMI/Pair-3: Selected inputs will be mixed to the left and right channels
and played through third pair of the HDMI Output.

12. HDMI/Pair-4: Selected inputs will be mixed to the left and right channels
and played through fourth pair of the HDMI Output.

Source Inputs

The source inputs which may be routed are described in this section.

1. Cluster Information: Cluster information show type of cluster and cluster
name.

2. Speaker Assignment: Speaker assignment can be used to configure to
which speakers the audio is routed to. The possible options are:

L Left

iVAM1-3

R Right

Page 74

C Center

LFE Low Frequency Effects

Ls Left Surround

Rs Right Surround

Bsl Back Surround Left

Bsr Back Surround Right

S Mono Surround

3. Input/Output Matrix: By checking the various boxes in this matrix, any
input channels can be freely routed to any output channels. This flexible
channel assignment is called a Free Mix. However, when the Speaker Mix
box is checked in the Output Options section, the associated row within the
matrix is automatically set to the speaker mix and the checkboxes are
grayed out indicating that you may not change them with a Free Mix
assignment.

Output Options

The optional settings in this section allow for customization.

1. Speaker Mix: This option selects whether an output has the Speaker Mix
or a Free Mix as set in the Routing Input section. The Speaker/Headphone
output is always in the Speaker Mix.

2. Solo/Mute: This setting determines whether or not the outputs are affected
by solos and mutes. The Speaker/Headphone output is always affected by
solos and mutes. Note also, that all outputs in Speaker Mix mode also are
affected by solos and mutes.

3. Mute on Headphone Insertion: This option controls whether the outputs
should be muted upon a headphone insertion. This setting can be adjusted
even for outputs whether they are in Speaker Mix or Free Mix modes.

4. Volume Control: This setting determines whether each output pair is
adjusted by the Volume Control knob. Speaker/Headphone outputs are
always affected by the volume control knob, as are any outputs that are in

Speaker Mix mode.

Typical Questions Regarding Output Routing

The questions and thoughts in this section are commonly asked by people when
setting up the licensed Output Routing capability.

What signal outputs can be controlled using the Output Routing
feature?

All the outputs on the iVAM1-3 can be controlled using the Output Routing feature.
This includes – Internal Speakers, Analog XLR outputs, all 4 pairs of AES outputs on
HD-15, AoIP Pair 9 and Pair 10 and all 4 pairs of HDMI outputs.

iVAM1-3

Page 75

How do the outputs behave if I do not purchase OPT-OUTPUT­ROUTING license?

If Output routing license is not purchased, the outputs are configured as follows:

1. Speakers: All monitored channels are always available on the internal
speakers. The left and right speaker assignment is determined by the
Speaker Assignment. Audio on the speakers is controlled by the Volume
and Balance knobs and is muted whenever a headphone is inserted into the
Headphone jack.

2. Analog XLRs: These outputs follow the same configuration as the internal
speakers. They are controlled by the Volume and Balance knobs and are
muted whenever a headphone is inserted into the Headphone jack. These
outputs also follow the solo/mute selections on the Audio Meter screen.

3. AES Pairs 1 through 4: The first 8 channels appear on these outputs in
numeric order. They are pre-fade, so they are unaffected by the Volume and
Balance knobs or headphone insertion. They are also unaffected by the
solo/mute selections on the Audio Meter screen.

4. AoIP Pairs 9 and 10: These outputs follow the same configuration as the
internal speakers. They are controlled by the Volume and Balance knobs
and are muted whenever a headphone is inserted into the Headphone jack.
These outputs also follow the solo/mute selections on the Audio Meter
screen.

5. HDMI Pair 1: These outputs follow the same configuration as the internal
speakers. They are controlled by the Volume and Balance knobs and are
muted whenever a headphone is inserted into the Headphone jack. These
outputs also follow the solo/mute selections on the Audio Meter screen.

6. HDMI Pairs 2, 3 and 4: These are not enabled in this case.

What is the difference between Global Output Routing and Output
Routing in Presets?

Both are used to configure the unit outputs. Global Output Routing is applied by
default when you select a source or when creating presets and when you don’t
change the Output Routing unique to any Preset. Changes to either of these are
disabled if the OPT-OUTPUT-ROUTING license is not purchased.

How do I route whatever is being monitored to the XLR and AES
outputs?

Using Global Output Routing (optional licensing upgrade), you may route any
signals to the XLR & AES outputs. You may route signals to the XLR outputs using
the Analog/XLR checkboxes and route signals to the AES outputs by using the

AES/Pair 1 to Pair 4 checkboxes.

iVAM1-3

Page 76

As shown in the above example, signals appearing on Audio Meter channels 1
through 8 are routed to AES Pair 1 and signals from Audio Meter channels 9 to 16
are routed to the Analog XLR outputs.

How do I have a downmixed pre-fade output on AES Pair-1
combined with a post-fade output on the Analog XLRs?

To downmix a pre-fade output on AES Pair-1, uncheck the Volume Control
checkbox for that AES pair. For a Post-fade output on the Analog XLRs, check
Volume Control checkbox.

How do I make the XLR outputs follow the Audio Meter screen
solos & mutes while the AES Pair-1 does not?

Make the settings shown in the Solo / Mute column:

The setting shown above determines that outputs will follow the Audio Meter screen
solos & mutes for the XLR outputs because the checkbox is checked. It is not
checked for the AES outputs, so they will not be affected by the solo & mute

iVAM1-3

Page 77

choices. This feature requires the optional OPT-OUTPUT-ROUTING output routing
license.

How do I route only specific monitored channels to the Analog
XLR outputs?

When the optional OPT-OUTPUT-ROUTING license is purchased, you may route
specific channels as shown below. Here Audio Meter channels 9, 11, 13, and 15 are
routed to the left analog XLR output and Audio Meter channels 10, 12, 14, and 16
are routed to the right analog XLR output. Unchecked channels are not routed.
Make sure the Speaker Mix selection is turned off to enable this selection.

The optional Global Output Routing feature works great. But what
if we don't want to create any Presets and want to monitor audio
only using Source Select? How would I configure different outputs
for Source Select choices?

Use the Global Output Routing settings to determine how the outputs are
configured for source select options.

The Global Output Routing feature allows channels to be routed or combined and
routed to various destinations. For example, channels 1 to 8 can be routed to AES
outputs, while channels 9 to 16 can be routed to Analog XLR outputs:

How do I keep the internal speakers muted and have audio only
on the analog XLR outputs?

When the optional OPT-OUTPUT-ROUTING license is purchased, in the Global
Output Routing configuration, do not select any Speaker Headphone
checkboxes for any meter channels as shown below, and then select the desired

iVAM1-3

Page 78

meters for Analog XLR. In this way, the internal speakers will always be muted, but
the audio will appear on the Analog XLR outputs (for amplified external speakers).
Make sure that the Speaker Mix checkbox selection is unchecked for Analog/XLR.

How do I ensure that the outputs are automatically muted when
the Headphone jack is inserted?

When the optional OPT-OUTPUT-ROUTING license is purchased, in the Global
Output Routing configuration, if the Mute on Headphone Insertion checkbox is
ON then the outputs get automatically muted when a headphone is inserted into
the Headphone jack.

As shown below, if a headphone is inserted then the output on the Analog XLRs will
be muted, while the audio on AES Pair 1 will remain on.

What are AoIP-Pair 9 and AoIP Pair 10?

AoIP-Pair 9: Selected inputs will be mixed to AoIP transmit channels 17 and 18.
Note that configuration for channels 1 - 16 is not supported. Use a Dante Controller
or Zman web interface to route these channels appropriately.

AoIP-Pair 10: Selected inputs will be mixed to Channel 19 and Channel 20. Again,
use a Dante Controller or Zman web interface to route the remaining pairs
appropriately.

iVAM1-3

Page 79

How do I ensure that my outputs are pre-faded but follow the
solo-mutes on the web interface? This will allow us to monitor
only the unmuted/solo Audio Meter channels on amplified stereo
speakers connected to the Analog XLR’s.

In the Output Routing setting, for the Analog XLR outputs, keep the Volume
Control checkbox unchecked and the Solo/Mute checkbox checked. This ensures
that the Volume Control is not applied to the outputs, while the Solos/Mutes are.

Preset Replication

Preset Replication allows you to copy presets from a master unit to multiple iVAM1­3 units. This can save a lot of setup time if multiple units all need basically the
same setup.

To start Preset Replication, click on the Preset Replication tab on the master unit.
This will start the unit discovery process and will list all the iVAM1-3 units that you
currently have on your network. The discovery process will continue for a period of
2 minutes. However, you may stop the discovery process sooner if you believe all
the units in the network have been discovered. Simply click the Stop Scan button.

Figure 4-21: Preset Replication Scanning Screen

Once all the units are discovered you may either copy the presets that are currently
created on the Master unit or can use an external preset file that you want to copy

iVAM1-3

Page 80

to any or all of the Target units. Note that any and all of the Presets that may
already be contained in each Target unit will be erased by copying the new
Presets.

Click either From Master Unit or Select Preset File. This determines the source
of the Presets to be copied. Preset Files would be files that you have previously
stored in the computer running the Web GUI.

You may add a descriptive name or version to the Presets being copied. This may
aid in remembering what tag or version of the presets are available on the unit. The
Preset name or version may be up to 10 characters in length.

Next, select the Target units from the list of units shown by checking or unchecking
each of the Target boxes at the left. Alternatively, you may click Select All to
select all of the units. Then select the Replicate Presets to Selected Devices
button. The progress of the Preset replication for each unit, as the Presets are being
copied, will be displayed in the Process column. When all of the Presets have been
copied to each of the selected units, you may leave this screen.

Import/Export Presets

Use the Import / Export Presets page to manage the Preset database in the
iVAM1-3. You may export the Preset database onto the computer hard drive for
security backup purposes or as a means to transfer it to another iVAM1-3. Likewise,
it can be used to import a Preset database from the computer hard drive into the
iVAM1-3. In this way, a Preset configuration may be only devised once and then
duplicated into all of the iVAM1-3 units in a system, saving significant effort.

The iVAM1-3 will create Preset Tags for the each set of Presets. Refer to Figure 4-

23. You may also change these Preset Tags, using the Preset Change Field. They
allow you to quickly resolve questions about which Presets on various units are the
most up to date. They will also allow you to determine whether Presets have been
modified. If the Preset Tag displayed contains the suffix "-dirty" then at least one
Preset has been changed in some way.

While exporting the file, the Preset Tag is appended to the filename, this allows you
to store multiple Preset files with different file name. For example, if the Preset Tag
is v1.0.0 then for iVAM1-3 the default filename would be "wohler_presets_iVAM1-3­v1.0.0.pdb" Do not change the file suffix and prefix (marked in red). However, you
may change the Preset Tag to any number or text to suit your requirements.

Figure 4–23: Database Export

Export Configuration

Use the following steps to save the Preset configuration in the iVAM1-3 to the
computer hard drive:

1. If you need to, revise the Preset Tag name, observing the advice in the
advice in the previous section.

2. Click the Export button on the Import / Export Presets page, as shown in
Figure 4-23.

3. A small Verify window will appear:

copying will proceed. After the Preset data has been written, the screen in
Figure 4-24 will appear, explaining what has been exported in an Export
Presets Summary. It will also note whether there were any errors in the
process. If there were any errors, repeat these steps to try again.

Figure 4–24: Database Export

Import Configuration

Use the following steps to copy the Preset configuration into the iVAM1-3:

1. Click the Browse button as shown in Figure 4-24 and select the Preset Tag
you would like to import.

2. If you want to allow existing Presets to be overwritten with imported Presets
of the same name, check the Overwrite an existing Preset box. It is a
good idea to do this.

3. Click the Import button. The copying will proceed. When complete, the
screen in Figure 4-25 will appear, explaining what has been imported in an

APPENDIX A: Software Upgrades

Introduction

This chapter describes how to download a software update file to your computer,
transfer it to a USB flash drive and install the update into an iVAM1-3.

Download the Software

The iVAM1-3 software update can be found at http://www.wohler.com, under
Product Downloads on the Products > iVAM1-3 page, in Support > Downloads >
Drivers & Software, or contact Wohler Customer Support for more information.

Unzip the downloaded update files to reveal two files. One will have a suffix of .wx
and the other will have a suffix of .md5sum. Both files are needed for the upgrade.

Update Methods

There are several software update methods. Select one of them, depending upon
your needs:

1. Local update from the front panel of the iVAM1-3: This straightforward
method does not require the use of the Web GUI. A flash drive containing the
update is plugged into the front panel USB socket and the update is then
accomplished using the self-contained menu system. If this method seems
most suitable, then refer to the Local Update from the Front Panel section of
this chapter.

2. Remote update using the Web GUI with a flash drive connected to the
iVAM1-3: It may be more convenient to update the product using a flash
drive plugged into its front panel USB socket, but controlled remotely via the
Web GUI. To update the product this way, refer to the Updating via the Web

GUI section of this chapter.

3. Remote update without a flash drive: This method allows you to update a
networked iVAM1-3 remotely without plugging a flash drive into its front
panel USB socket. To update the product this way, refer to the Updating an

iVAM1-3 Remotely section of this chapter.

4. Update multiple units remotely at once: This method allows you to update
multiple networked iVAM1-3 units at once, without plugging flash drives into
their front panel USB sockets. To update products this way, refer to the

Updating Multiple iVAM1-3 Units Remotely section of this chapter.

APPENDIX B: Dante Network Setup

Introduction

Installing the iVAM1-3 into an existing and functioning Dante network is virtually
plug and play. The iAM rear panel AoIP jack supports 1Gb/s and 100Mb/s Ethernet
devices in Dante Audio over IP network configurations.

The AoIP option on the iVAM1-3 supports Hitless and has 2 RJ-45 interfaces, a
primary interface and a secondary interface.

Additionally, an SFP slot is provided to receive the AoIP signal using network fiber
SFPs. These are 1G SFP slots. The SFP slot always acts as a primary interface.

On iVAM1-3, the AoIP source can be selected through the Source Select option.

The iVAM1-3 is set up at the Wohler factory to be used as a slave rather than a
master within the Dante network. Other devices or software, such as a Dante
Controller, are expected to be responsible for most device configurations and all
audio routing.

Please refer to the Dante Controller User Guide or other control device
documentation for specific network and device setup information. The next section
provides a guide to configuring the card and AOiP port.

What is in the iVAM1-3 for Dante

The Dante AOIP option consists of an Audinate Brooklyn II card directly connected
to the AOIP port. This port is dedicated to the card and should not be confused
with the Wohler unit Management port. These two ports must be on two different
subnets, one for the AOIP network and the other for access to the Wohler Web GUI
for management of the Wohler unit itself. Either one can be configured to have
static or DHCP addresses. The Wohler Web GUI indicates the presence of the Dante
card and the AOIP license but does not provide access to the various configuration
parameters internal to the card. The speed of the AOIP port is 1G default or
100Mbps.

The Audinate® Brooklyn II card has a simple process to set its initial IP address.
The initial factory setting for the card’s AOIP port is DHCP. When connected to a
DHCP based Dante network and the unit powered on, the Dante card sets the DHCP
server provided address as its default address.

Therefore, if the Dante network has a DHCP server, the unit can be inserted into
the network and can be configured further using the Audinate application, Dante
Controller, running on a host on the same DHCP based subnet.

If the Dante network is static based or if DHCP fails, the card sets a static Link Local
arbitrary address in the format 169.254.x.y, where x and y are each in the range 0
to 255. The mask is set to 255.255.0.0 to provide a ~65000 entry address space.

The Dante Controller host must also have a Link Local address to communicate with
the card over the unit’s AOIP port. Connect the AOIP port directly to a host (e.g.
laptop) running the Dante Controller, where the host address is preconfigured to an
arbitrary Link Local address (169.254.x.y, mask 255.255.0.0). The connection can
