CHAPTER 1: Installation
Introduction
verview
The iVAM1-1 is a 1RU multichannel multi-source audio/video monitor with basic 3G-
SDI 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 iVAM1-1 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 iVAM1-1 includes two 3G SDI inputs and it can monitor both video and audio
from them. ptional modules will allow decoding of an additional SDI input, MADI,
AES3, T SLINK, SMPTE 2110, and SMPTE 2022-6 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 iVAM1-1. The web server will
also allow you to view the audio meters remotely.

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.

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 urface
24” Front
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° Fahrenheit). Adjacent devices can be rack mounted (or stacked) in
proximity to the unit if this temperature is not exceeded. therwise, allow a 1RU
(1.75”/44.45mm) space above and below the unit for air circulation.
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.
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. nly qualified service personnel are to operate
the equipment with covers removed, and are to exercise caution to
avoid personal injury.

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.
peration 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.
ICES-003
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003 du
Canada.

CHAPTER 2: Local Operation
Operation
The iVAM1-1 can be operated easily and simply from controls on its front panel, as
described in this chapter. It may be accessed remotely in two ways, via the Wohler
Web GUI for administrative purposes 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 E of this
manual.
tartup
The iVAM1-1 will begin its startup process when it is connected to power. There is
no power switch. It is normal for the product to require about 45 seconds to start
