ICON LQ: Can LQ support 20KHz audio for use in production
I want to send 20KHz commentary / broadcast audio to several different locations around the world, is it possible with LQ?
Yes
LQ Uses the Opus audio codec with 12Khz audio bandwidth (as standard)
Frequency Response 100-12KHz
- LQ devices can support 20kHz (at 16 bit over 128Kbps data connectivity) LQ v3 and later firmware required by adjusting the Network quality setting (aka Local Audio Mix setting) . Within the Custom setting, selecting an Audio Bitrate of 128 Kbps will automatically set Bandwidth to 20 kHz,
Supports point to point and point to multi
Support multi-channel use. Example a 4wire source can be placed into different channel for distribution
The Eclipse matrix Hardware auto detects the LQ 4wire unit as a CCI-22
Latency through the box is around 25ms best case
Note that this 25ms best case assumes the following:
· Transmitting LQ unit has 5ms packets configured on port
· Receiving LQ unit has Jitter configured to 0ms – 60ms on port
So for instance, if 20ms packets are selected on the Transmitting LQ , the Receiving LQ unit will experience an increased latency of 15ms (5ms to 20ms = 15 ms delta)The reason for this is that the receiving LQ needs to wait for the first audio packet to arrive. So the packet size configured on the transmitting LQ unit directly affects this initial delay which remains.
TCP port 80 is management (setup ) port
TCP:80 is used for two purposes:
· Used by LQ unit to initiate a linking session with a reachable LQ-Master
· Facilitates access to the device’s CCM
It is mandatory for port 80 to be opened on the LQ-Master
TCP/ UDP port 655 is the Audio /data port (tunnelled port for all other TCP ports that the LQ boxes use)
Anytime a LQ unit is made reachable through port-forwarding, that information must also be configured within that LQ unit’s Network page (External Connectivity section). Specifically the external IP and Tunnel port that is forwarded to 655.
