CHAPTER 1: Installation
Introduction
Overview
The iAM-AUDIO units are 1RU/2RU multichannel multi-source audio monitors with
multiple standard copper connections and multiple S P module options facilitating
high density coax and optical fiber connections. The unit also accepts Audio over IP
signals via an Ethernet connector. Refer to the Specifications section or contact
Wohler Sales for more information.
The iAM-AUDIO 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) 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 self-contained web browser over a
network connection. Setup configurations can easily be copied to other iAM-AUDIO
units.
Each iAM-AUDIO can be configured with a number of presets. Nothing 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).
7. Protect the power cord from being walked on or pinched, particularly at plug
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.

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
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.
WARNIN :
The symbol to the left warns of electric shock hazard ins
ide 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.

Page 7
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.
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.
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.
Important
:
Heat gener
ated 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.

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
Startup
The iAM-AUDIO 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 two minutes to start up and be ready to use.
When the iAM-AUDIO 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 use the Mute, Un-
Mute or Solo capabilities to enable only the program channels you want to hear.
Front Panel
The front panels for the 1RU and 2RU models are shown in igures 2-1 and 2-2.
Operation and controls for the 1RU and 2RU models are identical, except for the
sizes of the displays and speakers.

Information
1. Speakers: Local near field audio monitoring is achieved through the use of class D
amplifiers. Two (left/right) low and mid/high range speakers are in the iAM-AUDIO-
1 (1RU) model. Two full range speakers are in the iAM-AUDIO-2 (2RU) model.

Page 10
2. Headphone Jack: A 1/4" jack for an optional headphone is provided on the front
panel. Speaker audio mutes when headphones are plugged in.
3. Volume: This controls the speaker and headphone output level for the entire mix.
4. Balance: This controls the relative 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. Adjust / Aux Volume: Turning this control right or left moves a white selection
box from channel to channel on the metering screen. Pressing the Adjust control
solos the selected channel. If a muted channel is selected with this control, it is
unmuted and soloed. Pressing the Adjust control again or touching the meter area
anywhere removes the channel solo.
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-AUDIO or to a PC. Software updates are controlled from the Web GUI.
7. Menu / Option Display: This touchscreen display is used for a limited amount of
setup and status display. The large majority of setup functions are performed using
the Web GUI.
8. Level Meter Display(s): 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).
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 panels for the 1RU and 2RU models are shown in igures 2-3 and 2-4.
