Page 44: Chapter 3: Audio Routing
Chapter 3: Audio Routing Audio I/O routing with the AEROs is very flexible, but admittedly, can seem somewhat complex at first. Once you understand the concepts, it’s really not that difficult. The AERO.20, AERO.200, and AERO.2400 support: • Dual 3G-SDI I/O •... -
Page 45: Baseband I/O Routing- Aero.20, Aero.200, Aero.2400
Baseband I/O Routing– AERO.20, AERO.200, AERO.2400 The audio I/O is configured in the System -> Baseband I/O menu. This menu is laid out logically from left to right, configuring inputs to outputs, following the block diagram / workflow of the AERO unit. Input Routing The audio core can accept up to 36 input channels, and each AEROMAX instance supports up to 10 audio channels in and out, which are configured as a 5.1+2+2,... -
Page 46: Output Routing
System -> Baseband I/O -> Core Input Source Figure 32 - Audio Core Input routing Once the desired input audio sources are routed to the Audo Core Inputs, the audio then needs to be routed to the inputs of the AEROMAX instance. This is handled in the (AEROMAX) Instance Source, which directly to the right of the Core Input Source menu System ->... -

System -> Baseband I/O -> Main Figure 34 - Baseband Audio Reference Clock configuration Input Status The Input Status tab provides status for each physical base band input, along with the status of both power supplies. Sample Rate Converters (SRC) There are 36 channels of hardware Sample Rate Conversion (SRC) built into the AERO.20, AERO.200, and AERO.2400. -
Page 49: Core Input Source
Coded audio, such as Dolby Digital (AC-3) and other formats can never be passed through Sample Rate Converters without being destroyed. Properly managing clock domains is required when using coded audio. Core Input Source The Core Input Source tab is where the physical base band inputs are routed to the Audio Core Input channels Figure 35 - Baseband Audio Core Input routing Each of the physical inputs can be routed to any of the Core Input channels. -
Page 50: Instance Overview
The Instance Source tab is where the Audio Core Input channels are routed to the AMX Instance inputs. Each instance will have its own settings, and the available options are: • Off • Core 1/2 • Core 35/36 Figure 36 - AEROMAX Processor Input routing Instance Overview The Instance Overview tab is a status display of all the I/O routes, both input and output, made for each AEROMAX Engine Instance. -
Page 51: Core Output Source

Page 52: Audio
Figure 39 - SDI Output Overview tab Audio The Audio tab is where the output audio is configured. The Embed control enables or disables embedding audio from the AMX processing engine or Core Audio, along with pair shuffling. When the Embed control is disabled, the audio from the SDI Input passes through directly to the SDI Output, but that completely defeats the purpose of having an audio processor inline. -
Page 53: Video
Video The Video tab is where the video compensating delays are configured. The video delays allow for audio/video sync to be maintained on the output of the unit. These are manual controls and must be adjusted during setup. The AERO is shipped with no video delay added, so it must be set on each SDI Output for audio and video to be synchronous. -
Page 54: Aes3 Outputs
AES3 Outputs The AES3 Outputs tab is where the routing for the AES3 Outputs is configured. Similar to the SDI Outputs tab, there’s an Overview / Status tab at the top, and then the Assign tab is where the routing is configured. Figure 42 - AES3 Outputs Overview tab The available output source options for the AES3 Outputs are: •... -

Page 57: Aoip I/O Routing
PTP clock (IEEE-1588) or a Livewire clock. PTP is the industry standard clock when using AES67 or SMPTE ST 2110 workflows, and Livewire clock is a clock option when using workflows based on Telos Alliance Livewire. Livewire systems can also use PTP clocks instead of a Livewire clock. -
Page 58: Sample Rate Conversion
Figure 47 - PTP / Livewire clock page Sample Rate Conversion Since the AoIP section uses a separate, and different, reference clock than the audio processing engine and baseband I/O, clock management is essential. To aid in this, sample rate converters (SRC) are included in between the AoIP section and the audio processing engine. -
Page 59: Chapter 4: Audio Over Ip
NMOS IS-04, defined by AMWA (www.amwa.tv), is how stream discovery is typically handled with SMPTE ST 2110 workflows. Livewire+, from the Telos Alliance, includes stream discovery as well as audio, and additional features as well At the time of this writing, the AERO units do not support the NMOS suite, but do support manual configuration of AES67 / SMPTE 2110-30 flows, including uploading and downloading of SDP files. -
Page 60: Clock Mode
Clock Mode Clock Mode allows the selection of whether the AoIP clock is either: • PTP (IEEE-1588) for AES67 or Livewire streams • Livewire clock for use with Livewire streams It is also possible to enter the PTP Clock Domain value. Ensure that this matches the clock domain value of the PTP primary clock generator. - Page 61 • Receive 1 (2ch) • Receive 2 (2ch) • Receive 3 (2ch) • Return Receive 1+2 (8ch) will be an 8-channel stream, where channels 1-6 are a 5.1-ch input for Program 1 to be downmixed, and channels 7 and 8 are the input of Program 2 Receive 1 (2ch) will be a 2-channel stream, which is the stereo input stream to Program 1...

Page 63: Channel
Channel This field allows the source stream to be entered directly and displays the address of the current input stream. Input Stream Port Number The default port number that AES67 and Livewire+ streams use is 5004, but it is sometimes desirable to change the port number being used. The AERO supports receiving streams at different port numbers. -
Page 64: Fifo Buffer
This allows you to load an SDP file for an incoming AES67 stream. The SDP file contains information regarding the input stream, such as sample rate, number of audio channels, multicast address and port number, RTP header information, and more. This information is necessary for AES67 audio streams, whereas Livewire streams contain this. -
Page 65: Assign" And Memory Slots
It is important to know that coded audio, such as any Dolby audio, cannot be passed through a sample rate converter without being destroyed. “Assign” and Memory Slots The furthest column to the right on this page includes memory slots to store the address and other relevant information regarding commonly used input streams. - Page 66 When the AMX engine is AMX5.1, there will be: • Send 1+2 (8-ch) • Send 1 (6-ch) • Send 2 (2-ch) • Send 3 (2-ch) • DD+ Encoder Out* • DD+ Encoder Out 2* • Send Send 1+2 (8-ch) will be an 8-channel stream, where channels 1-6 are the 5.1-ch output of Program 1, and channels 7 and 8 are the output of Program 2 Send 1 (6-ch) is a 6-channel stream containing the 5.1-channel output of Program 1 Send 2 (2-ch) is a stereo stream containing the output of Program 2...

As an example, the AES3 Reference may be missing or at the wrong sample rate; the unit expects to lock to 48 kHz. The AERO defaults to an internal 48 kHz reference if the external reference is removed or missing. This allows audio to continue, but with asynchronous inputs and outputs (due to the sample rate converters on each input pair). -
Page 91: Audio Fixed By Re-Boot
Moral of the story: make sure the input audio is immaculately clean or it will sound worse in surround! Audio fixed by re-boot Re-booting sometimes fixes audio problems by interrupting the AES3 signals, thereby causing equipment downstream to re-lock to the incoming signals. Selecting a preset with minimal processing (i.e., Protection Limit) may shed further light on the problem. -

Nielsen watermark encoding does not cause additional latency. Verance Aspect watermark encoding adds 26 ms additional latency. Disabling sample rate conversion (SRC) for any AES input decreases the latency on that pair by 1.5 ms. Note! If a Dolby encoded bitstream is connected to an AES input the SRC must be disabled. - Page 96 GPI E (Active Low) GPI E (Active Low) Ground GPI F (Active Low) Ground GPI G (Active Low) GPI H (Active Low) GPO A No Connection GPO B Status OK GPO C No Connection GPO D Ground GPO E +5 V, 150 mA Status OK GPO A GPO B...
