Cobalt Digital BLUE BOX GROUP HDMI-To-SDI HDMI-to-3G_HD_SD-SDI - Manual (Page 2)

Audio Embedding
BlueBox™ HDMI>SDI provides embedding to the SDI output in either of two modes as
described below using the DIP switch bank on the underside of BlueBox™ HDMI>SDI. Refer
to label on unit for switch positions.
• SW 6 – OFF: HDMI channels 1-8 routed to SDI channels Emb Ch 1-8 (Emb Ch 9 thru 16
are muted in this mode).
• SW 6 – ON: External analog stereo audio input AUDIO IN (L/R) routed to
Emb Ch 1 and 2, respectively (Emb Ch 3 thru 16 are muted in this mode).
Unbalanced Audio Levels and This Device
The unbalanced “RCA” audio inputs on this device will correspond to 0 dBFS when driven with a 2.2 Vrms
input. Consumer audio is specified in dBV with a nominal (or recording) level of -10 dBV. The 2 Vrms
maximum input level corresponds to +6 dBV. The unbalanced analog inputs on this device allow for 16 dB of
headroom above the nominal -10 dBV consumer level (“headroom” is the range between the maximum and
nominal audio levels).
Professional balanced analog audio levels in the US typically use a +4 dBu nominal level with 20 dB of
headroom (-20 dBFS). The maximum level for balanced analog interfaces is +24 dBu.
The headroom difference between consumer and professional audio will result in a lower RCA consumer
level when converting from professional balanced analog audio. For example, if pro level analog audio is
received and transmitted via AES or embedded SDI to a receiver converting to RCA analog audio, the
output will be 4 dB lower, with a nominal level of -14 dBV.
Channel Line-Up of HDMI vs. Standard SDI Conventions
To maintain conformance with CEA-861D HDMI audio channel line-up specifications and industry standard
SDI convention, this device lines up audio as shown below with a swap between the C and LFE channels
.
BlueBox™ HDMI>SDI and SDI>HDMI converters bilaterally conform to the conventions shown here, with
back-to-back connection resulting in proper channel line-up for HDMI and SDI. Connection to non-
conforming devices, however, may result in an unexpected channel 3/4 swap which can be remedied using
an SDI audio crosspoint.
Status Indicator
BlueBox™ HDMI>SDI has a Status LED on the side of the unit which functions as follows:
• Solid ON – Input lock OK.
• Slow Flash – Unlocked to input video; input video not present
• Rapid Flash – Detected input video is of format specifically not supported
