Send Audio to and from a DAW
CQ can send and receive multichannel audio with a built-in audio interface that
connects to a computer or device via USB-B. The maximum number of channels
that can be sent and received are:
CQ-12T: 16×16 (48/96kHz)
CQ-18T: 24×22 (48/96kHz)
CQ-20B: 24×24 (48/96kHz)
For capture and playback of an event, or for virtual soundcheck, signal is generally
only sent or received at any time. In a studio environment however, sending and
receiving signal at the same time is often required. This guide describes sending
and receiving separately. For bidirectional use, simply ensure that audio is being
sent from the DAW to the CQ using different channels than those being used to
send audio from the CQ to the DAW.
 CQ mixers are Core Audio compliant so no driver is required; for lower latency
connection with Windows systems, download and install the required ASIO driver from
the A&H website: https://www.allen-heath.com/cq.
Send Audio from the CQ to a DAW:
1.
Connect the CQ to the computer or device
using a standard USB-B cable.
2.
Go to CONFIG / Digital Audio (Symbols) /
USB/SD to set up the connection.
3.
Select a point in the signal path of an Input
channel to record from using Source Point
