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

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.

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). The

HD-SDI inputs (In 1 and In 2) can be up to 150 meters (492 feet) in

length when used with HD signals and 75 meters (246 feet) in length

when using 3G signals.

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. The internal circuitry ground is connected to

the chassis.

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.
