Output Structure
This page explains the rationale and procedures designers should follow when designing the output side of a sound system.
Broadly speaking, it is designed in the following steps.
Broadly speaking, it is designed in the following steps.
1. Speaker (SP) configuration: number of SP
First, the location and number of SPs required for the space must be determined. These are determined by the location and size of the audience area and the SP coverage area.
Please see this page for more details.

2. Output Number of DSP channel
The number of DSP channels must be determined. These are determined by the 1. SP unit configuration, the required number of delays depending on the SP position, and whether it is monaural or stereo. Please see this page for more details.
3. Number of Amplifier (AMP)
The quantity of AMP must be determined. This is also determined from the SP specifications and number determined in 1. Please refer to this page for the relationship between AMP and SP numbers.
* The linked page describes the basic concept, but in actual practice, an AMP with a higher rated output is selected for the SP, and the volume of that AMP is often reduced. The reason is that a music signal equivalent to the SP's rated capacity (PHL) contains peaks of higher levels, and these peaks must be amplified accurately without distortion.
