2.7.4 Input Delay
HCL-804A supports AES / EBU + analog signal input. When one channel fails, the sound amplification system works
completely without breakpoint. Therefore, before mixing, adjust the delay difference between the analog input and the
digital input, align the two sets of signals before mixing.
Method of adjusting the delay (optional):
1. The overall time delay parameters of the system are obtained from the equipment manufacturer, that is, the time
delay from the audio input to the audio output.
2. Measurement was performed by the software such as Smaart Live, Systune, etc
Note: analog input delay and digital input delay, the actual setting is the two channel delay difference, such as digital
input front-end device delay is 3ms, analog input front-end device delay is 1ms, adjust step for 1 sample (0.02ms)
namely: the digital input lags the analog input by 2ms, please set the analog input delay as 2ms, digital input delay as
0ms.

2.7.5 System Delay
The system delay needs to be set with the whole sound reinforcement system. The maximum 1000ms delay can be set,
and the default is 0ms, and the delay function is OFF.
