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).

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.
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.
