Chapter 3: System Connection
Step 4. Connect an AVS-HDB-RX to the he AVSC-5DA1-HDB’s HDBaseT output port
with twisted pair.
Step 5. Connect a speaker, headphone, or amplifier to the AVSC-5DA1-HDB’s AUDIO
OUTPUT port.
Step 6. Connect a control device (e.g. PC) to the RS-232 port of the AVSC-5DA1-HDB or
AVS-HDB-RX (bi-directional RS-232 control, either end is available).
Step 7. Both AVSC-5DA1-HDB and AVS-DB-RX have IR IN and OUT. When one model
is connected to an IR receiver, the other model should connect to an IR
transmitter.
For example: When “IR IN” of AVSC-5DA1-HDB connects with an IR receiver,
the IR transmitter must connect to the IR OUT of the AVS-HDB-RX.
NOTE: The IR signal is transmitted bi-directionally between the AVSC-5DA1-
HDB and the AVS-HDB-RX.
Step 8. Select the MIC level and connect the right microphone to the MIC input port.
MIC audio will be transmitted to the AUDIO OUTPUT port and mixed with
source audio.
tep 9. Connect the 12-VDC power adapter to the power port (AVS-HDB-RX gets power
from AVSC-5DA1-HDB via PoC).
NOTE: The AVSC-5DA1-HDB supports unidirectional PoC, i.e., If the power
adapter is connected with AVSC-5DA1-HDB, the AVS-HDB-RX can get
power from AVSC-5DA1-HDB.
3.4 Microphone Connection
The AVSC-5DA1-HDB has one 3-level microphone input port to accommodate different
microphone input modes, including 48-V phantom power mode, MIC mode, and LINE
mode.
48-V phantom power input
48-V phantom power input has good frequency, high input impedance, and high
sensitivity.
When switching to “48-V,” the MIC input will provide 48-V of phantom power. This is
only used for the condenser microphone.
Connect the microphone in this way: “+” connects to positive, “-” connects to
negative, and GND connects to ground.
