Chapter 1: Introduction
A good conference sound reinforcement system is not
a front end (microphone/sound source), mixer, audio
processor, power amplifier and speakers and other
equipment that can be connected together. This can
easily lead to a lot of investment, but cannot achieve
satisfactory results, the sound of language
amplification is blurred, the microphone is easy to
whistle, and the sound quality is tasteless when the
music is played back.
As a system problem, the sound reinforcement system
must comprehensively consider the above problems in
the system design. On the basis of selecting
electro-acoustic equipment that meets the functional
requirements, it is necessary to pass system design
and system debugging in order to achieve a sound
reinforcement effect that satisfies users.
The common problems of conference sound
reinforcement system are: howling when the
microphone is on, insufficient volume, sound image
shift, and uneven sound field. This kind of inaudibility
can be caused by low volume, shriveled sound, and
confusion in the sound field caused by the time
difference between the reflected sound and the direct
sound, which is actually insufficient speech intelligibility.
Therefore, solving the speech intelligibility of the sound
reinforcement system has become the ultimate goal of
our sound reinforcement system. We have developed a
series of targeted related products according to the
characteristics of conference sound reinforcement
applications.

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)
