AMP2A-10S User Guide

Description

Audio Connections

Connection of the audio feeds is straightforward. Please refer to the

system interconnect block diagrams in Figure 1–5 on page 14 for

clarification of the general signal paths into and out of the AMP2A-10S

unit.

Analog inputs via the 3-pin male Phoenix connectors are configured for

40K  balanced connections.

Electrical Interference

Care should be exercised to avoid mismatched cable types and other

similar causes of undesired reflections in RF signal systems. If severe

enough, such reflections can result in undesirable electrical interference

in the audio signals.

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

common is connected to the chassis.

Power

The unit comes with a standard 24VDC/3.0A internal power supply

and connects an A/C mains power source (65W, 100 to 240 VAC, 50/

60Hz) to the IEC connector provided on the rear panel of the unit.

Description

The unique audio design of the AMP2A-10S has two important

advantages. First, it provides optimally focused sound in an ultra near

field (1 to 3 feet) environment. This allows higher SPL for the operator

while reducing overall ambient sound and adjacent bay crosstalk.

Second, electronic rather than acoustic cancellation of bass frequencies

provides positive audible detection of reversed polarity (“out of

phase”) audio feeds. A unique LED display also visually shows

“phase” (polarity) relationships of the signals selected for monitoring.
