Analog Audio Embedding (Transmitter)
Analog audio on the 3.5 mm input on the transmitter functions in two modes, which can be
configured via SIS commands (see
Audio Input Configuration (Tx only) on page 22):
• Analog audio over DTP — Standard analog audio over DTP is digitized and
transported simultaneously with the embedded digital audio on the HDMI signal.
• Embedding the analog audio input — The analog input signal is converted to 16‑bit
2.0 LPCM, with 48 kHz sampling frequency, and embedded onto the HDMI signal.
Configure the analog audio embedding via SIS commands with three options:
• Auto (default) — The original embedded digital audio passes. If audio packets are
not detected, analog audio is embedded.
•
Force analog audio embedding — Analog audio is always embedded.
• No embedding — Existing embedded digital audio passes.
HDMI Audio De‑embedding (Receiver)
Using the rear panel toggle switch (see figure 3 ,
E
on page 8), the DTP2 211 receiver
can be configured to:
• DOWN (default) — HDMI digital audio pass‑through and HDMI audio is de‑embedded.
•
UP — HDMI digital audio pass‑through and analog audio over DTP2.
NOTE: Whether the audio configuration switch is UP or DOWN , the embedded digital
audio on the HDMI signal remains intact.
