Safety Symbols
Chapter 1 Installation
FCC Compliance
WARNING:
The symbol to the left is a warning to be careful of electric shock. Do
not open the top cover with the power cord attached.
FCC Compliance
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 his own expense.
Unpacking
Unpack the AMPx-E8 Series monitor and inspect for any apparent physical
damage that may have occurred in transit. If the unit has been damaged,
contact Wohler customer support for assistance. (Wohler’s contact
information is on page ii of this document.)

Installation Recommendations
• A warranty card
Note:
We recommend you retain the shipping carton for future
use.
Installation Recommendations
Mounting
The unit is designed to install into a standard 19" rack mounted at ear
level for best high frequency response and visual observation of the
monitor screen. Please adhere to the following clearances:
Clearance Surface
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. Otherwise, allow a 1RU (1.75”/44.45mm) space above and
below the unit for air circulation.
Important:
To reduce noise, the monitor does not have any fans. As a result, the
heat generated by the class D power amplifiers, power supplies, and
other components is vented by slots in the side of the unit. Therefore,
as a safety precaution, you must allow proper ventilation on both sides
of the unit.
Sympathetic Vibration
Sympathetic vibration from other equipment (cables, etc.,) in the rack
may be serious enough to interfere with the unit’s sound quality. The
use of thin card stock and/or felt or foam weather-stripping type
821016: AMPx-E8 Series User Guide

Chapter 1 Installation
Installation Recommendations
materials between adjacent vibrating surfaces, or tying up loose cables,
etc., may be required to stop vibrations external to the unit.
Mechanical Bracing
Even though the 2U models are fairly heavy, the 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.
Audio Connections and Cable Recommendations
We recommend that you limit the length of the cables that you use for
feeding HD-SDI signals sources to the HD-SDI inputs of the AMPx-E8
Series units and that you use a Belden 1694A cable (or equivalent).
Note:
The connections of all DB-25 connectors are compatible with
Tascam DB-25 to XLR cable assemblies. Consult the factory
for availability. All rear panel connectors are female except
for the XLR connectors.

Electrical Interference
Be careful to apply proper input termination settings and 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 24VDC/3.0 A internal power supply
and connects an A/C mains power source (65W, 100 to 240 VAC, 50/
60Hz) through the IEC connector provided on the rear panel of the unit.
When the mains plug or appliance coupler is used as the disconnect
device, the disconnect device should remain operable.
Installation
Initial Setup
Power Up
1. Carefully install the monitor into a standard 19”-rack.
2. Connect all signal cables to and from associated equipment.
3. Connect the power cord from the monitor to A/C mains.
The AMPx-E8 Series monitors are factory-configured so that all settings
are non-volatile. When power to the unit is cycled (off/on), the unit will
restore itself so that each setting such as channel selection(s), input
type, and so on, are automatically restored to the unit’s previous
factory setting. However, you can custom configure the monitor to
automatically restore your configuration settings on power up. Refer to
Setup Menu on page 55 for details.

• Speakers: The AMP2s features two mid-range speakers (left and
right) and one woofer speaker. The AMP1s have two woofers. All
models of the AMPx-X8 Series contain high performance
transducers driven by three power amplifiers. Two amplifier/
driver combinations handle midrange and high frequency
information in the left and right (stereo) speaker channels, while the
third channel reproduces and sums the left and right channel
information below the crossover point in the woofer (bass) speaker.
Note that the woofer channel is not a dedicated LFE (sub-woofer) or
center channel.
• Level Meters (1 through 8): Source channels 1 through 8 are
displayed through eight audio level meters (four on the left side;
four on the right side). These level meters, high-resolution LED bar
graph displays and feature a dynamic range of 66 dB with PPM dot
over VU bar ballistic characteristics.
• Headphones (1/4” Jack): Select the headphone audio sources as
you would for the internal speakers. When you plug in headphones
the speakers will mute.
• Volume (Rotary Knob): This control adjusts the loudness of the
audio reproduced by the internal speaker channels or connected
headphones.
• Balance (Rotary Knob): This control adjusts the volume balance
between the left and right speaker channels. Note that this control
attenuates the signal from the source, so that the left and right bass
frequencies (summed together and reproduced in the woofer
channel) will respond to balance adjustments in tandem with the
left and right speaker channels.
• Level Meter Brightness (Potentiometers, Left and Right): Use a
small slot screwdriver to adjust the brightness of the bar graph
meters using these two recessed trim pot controls. The left control
adjusts the brightness of the left four LED bar graphs and the right

The LCD screen displays various parameters and settings, and is also
used to configure/program the monitor. The features of the LCD
screen (shown in Figure 2–3 through Figure 2–6) include:
• Mix Status: Displayed on the top right and top left corners of the
LCD screen, the Mix Status indicates how the current input signal
is mixed to the internal speakers.
• Source Status: Displayed in the top center of the LCD screen, the
Source Status indicates the current signal type and current input
currently audible in the internal speakers. If a preset has been
recalled, this area displays the name of the preset until a monitoring
or input change is made.
• SDI Groups/Dolby Signal Type: Displayed in the bottom left and
bottom right corners of the LCD screen, these groups indicate the
SDI channels that are currently mixed to the internal speakers. In
the case when a Dolby signal is mixed to the internal speakers, the
bottom left corner will be blank and the bottom right corner will
display the Dolby logo, PCM, DAT, or --- (no input signal).

balanced (110 ) AES signals. Inputs are internally connected to the
loop-through outputs. These inputs are referred to as AES2 in the
LCD screen. If you are connecting downstream equipment to the
AES loop-through outputs of this connector, then you should
unterminate this connector. If you are not connecting downstream
equipment, then you should terminate them. Refer to Terminating/
Unterminating Inputs on page 40 for details.
