7. The Power LED is illuminated when the Power switch is ON. It will dim as the |
batteries lose power, thus giving an indication of remaining battery life. |
8. The Power Switch applies power from the external supply or the batteries. |
When power is applied, the AESDA runs internal diagnostics, culminating in an |
LED display test where the 32 LEDs in the three displays are illuminated in |
sequence, then extinguished in the same manner. The unit then goes into its |
normal operating mode. |
9. The Digital Monitor Select switch selects whether “Digital Info” (digital signal |
parameters) or “Fault Type” information is displayed on the vertical ten- |
segment Digital Monitor LED array. |
10. Phones Out Jack provides a |
source received by the AESDA. Peak output level is +4dB, and the output is |
capable of driving headphones from 16 to 100 Ohms impedance. It can also be |
used to feed an unbalanced line input. The left channel (A) is connected to the |
tip, the right (B) to the ring, and the sleeve to common of the unbalanced |
3.5mm TRS jack. |
11. Phones Vol(ume) Control adjusts the analog audio level present on the |
Phones output (3.5mm) TRS jack. The setting of this control has no effect on |
the Analog Outputs or the meters. |
12. The Battery Compartment is a slide out drawer that accepts four “AA” size |
cells. Either alkaline cells or |
(NiMH) or |
upon several factors, including load impedance, output level, the use of |
headphones, and the mode of the level meters. Typical loading will provide |
Controls and Functions
1.AES/EBU Input Connectors are provided for Digital Audio input. The BNC connector provides an input for 75 Ohm unbalanced S/PDIF audio, and the female XLR provides an input for 110 Ohm balanced AES/EBU audio. Both inputs are transformer and DC isolated (up to 50V), and accept AES/EBU and S/PDIF signal levels ranging between 5V
2.VU Meters, two eleven segment LED arrays, can display either the digital input level or the analog output level. The first ten LEDs are green; the eleventh is red. Two measurement scales are provided, one for the digital input, which is in dB

3.Analog Output Jacks are balanced male XLR connectors, capable of driving loads from 600 Ohms to near infinity at output levels of up to +27dBV, although the outputs are metered only to +18dBV. Output noise is less than
4.Output Level Controls independently control the level presented at the analog outputs. The level of each output may be monitored on the VU meters by selecting Analog Output with the Meter Source Select switch.
5.The Meter Mode Select switch controls how the VU Meter information is displayed. In “DOT” mode the VU display will illuminate the LED that most corresponds to the output level at that instant. In “BAR” mode, the VU display operates as a conventional
6.The (VU) Meter Source Select switch controls whether the level of the Digital Input or the Analog Outputs are selected for monitoring on the VU Meters. In the “D(igital) Input” position, the Analog level of the decoded Digital Input is displayed. In the “A(nalog) Output” position, the level present at the Analog Outputs XLR Connectors after the Output Level controls is displayed.
about four hours of operation with fresh batteries. The AESDA does not have |
internal battery recharge capability. |
13. The 6VDC external power jack is a 5.5mm x 2.1mm size with the center |
contact wired positive and the barrel contact negative. When a plug is inserted |
into this connector, the internal batteries are disconnected. A 6VDC 2.5A plug- |
in power supply is supplied with the unit. Input voltage can be anywhere from |
4.8VDC to 15VDC, provided the power source can deliver at least 12 Watts |
peak. This wide input range allows the AESDA to be powered from lantern |
batteries, auto batteries, and camera batteries, as well as the familiar AC “wall |
wart” |
14. The Digital Monitor |
and fault diagnostics. The type of information shown on this display is |
controlled by the Digital Monitor Select switch. In the “Digital Info” position, the |
display shows the detected sample rate, the type of data present, if the data is |
consumer or professional mode audio (if an audio stream is detected), if pre- |
emphasis is enabled, and if a fault is present. In the “Fault Type” position, it will |
indicate the type of fault(s) present, if any, and also if no fault is detected. The |
types of faults annunciated are Hardware (internal diagnostics), No Lock (or no |
signal present), Parity or Bit Length error, CRC error (if the audio data present |
is in Professional mode), Signal Confidence (wave shape, level or symmetry is |
borderline or |
No Fault Detected. |
