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

• SDI channels Emb 1-8 are normally routed to HDMI channels 1-8.
• SDI embedded channels 1/2, 3/4, 5/6, or 7/8 can be de-embedded to the stereo
AUDIO OUT (L/R) RCA connectors using DIP switch bank as shown on the unit label.
(Note: serial numbers 368880R and earlier do not offer Ch7/8 de-embedding)
Unbalanced Audio Levels and This Device
The unbalanced “RCA” audio outputs on this device correspond to 2.2 Vrms output when sourced from a
unity-gain 0 dBFS digital sine-wave source. Consumer audio is specified in dBV with a nominal (or
recording) level of -10 dBV. The 2 Vrms maximum output level corresponds to +6 dBV. The unbalanced
analog outputs 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™ SDI>HDMI and HDMI>SDI 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 downstream devices not conforming to both SDI and HDMI conventions may require switch
SW4 set to ON (custom) to swap the C and LFE channels so that HDMI has Ch 3 as C and Ch 4 as LFE.
HDMI/DVI Mode Switches
BlueBox™ SDI>HDMI can typically automatically detect connection to a downstream device
as either an HDMI port or a DVI (monitor) port. However, switches SW1 thru SW3 allow setting
BlueBox to force a DVI output suitable for direct connection to monitors using a DVI input in
case the connection is not detected by the monitor. (Refer to illustration on rear page of this
manual or label on unit for switch positions.)
• SW3 – Set to ON to allow manual control of HDMI/DVI mode.
• SW2 – Set to ON to force DVI output mode.
• SW1 – Set to ON to force RGB color space (intended mode for monitor usage).
Note: Connect monitor to BlueBox™ SDI>HDMI and then set switches to ensure monitor gets
handshake to “see” connection.
