Linear Acoustic AERO.qc User Guide
•
Cal Mic Input (OPTION): Analog line-level input for a calibration microphone used
by the built-in real time spectrum analyzer (RTA). Also provides +/-15V DC output
to power an external mic to line preamplifier. Please see Chapter 8 for pinout or con-
tact the factory for details.
•
Monitor Control (OPTION): Inputs for an external rotary encoder for volume plus
Mute and Return to Reference switches and LED indicators. See Chapter 8 for pinout.
•
Analog Monitor Out (OPTION): +4dBu output controlled by front panel or exter-
nal volume control and mute.
NOTE: Analog outputs are normalized to produce +4dBu with a -20dBFS input
signal; users must provide proper gain matching for best results.
•
Metadata I/O: RS-485 connection accepts the metadata output of any Dolby equip-
ment (DP572, DP570, etc...) or any Dolby-compatible metadata source. Used to con-
trol upmixing and other functions.
•
SDI Input: Any of the 16 possible audio channel from an applied HD/SD-SDI signal
can be de-embedded and used in place of or along with AES inputs. This can be se-
lected in the System Options->I/O Options menu on a pair-by-pair basis.
•
SDI Output: Up to 16 audio channels, including any of the Main outputs. Audio chan-
nels present in the applied SDI signal can also be passed through in a bit-accurate man-
ner, allowing for example pre-encoded Dolby E or AC-3 bitstreams to pass untouched.
AES outputs remain active in parallel with embedded audio.
•
GPI/O: Currently not used.
•
ETHERNET: Automatically senses 100 or 1000BASE-T Ethernet connectivity.
This connector is not currently supported an as such it is recommended that it not be
connected to any network.
•
Future: Extra RJ-45 connector for future I/O use.
•
USB: Used for software updates via factory instruction. Please Do Not connect any
USB devices to this connector without factory guidance as this may affect the perfor-
mance of the unit.
NOTE: Please do not connect anything to the USB connector without specific in-
structions from the factory. Permanent damage can occur!
