Choose a mounting accessory that matches the speaker’s form factor and the installation surface, such as a yoke for vertical or horizontal mounting to walls, beams, or other structures, or a pole mount bracket for compatible slim line array speakers. Also consider the required orientation, available space, and the manufacturer’s installation requirements before selecting the accessory for your PA system.

When selecting remote control panels for a PA system, confirm that the panel is compatible with the system’s processors or amplifiers and choose the controls needed, such as switches, volume rotaries, or both. Also consider the installation location and wiring requirements, since some panels use wall-mount designs with CAT 5 cable for RS485 communication and power.

Input and output expansion accessories can add eight channels to a PA system by converting analog microphone or line signals to digital audio, or digital processor signals back to analog audio. Using YDIF digital audio transfer and Ethernet-based control for compatible input expanders, integrators can connect more sources and outputs to a larger processor-based design.

Review whether PA system accessories connect through CAT 5 cabling, RS-485, Ethernet, or a digital audio link such as YDIF, and confirm that the connected processor, mixer amplifier, or power amplifier supports the required interface. For control panels and expanders, check the available button or rotary controls, power delivery, remote preamp or network-monitoring needs, channel count, and supported sample rates.
