Introduction

Integrated systems

All the current Bose Portable PA systems are integrated systems with built-in mixers, digital signal processors, power amplifiers, low-frequency and mid-high frequency drivers. Provide a sound source (microphone, instrument), and you have a complete sound system. However, since all of these systems have inputs and outputs, they can be part of a larger signal flow with components in front of, and following them. Connecting Gear is about making the connections to and from the Bose systems.

Core Principle of Signal Flow

This article will discuss signal flow, cables and device names in this order:

Source to Destination
Throughout this site, we talk about connections by following the signal flow from the source to the destination. examples:

  • Microphone to Mixer to Loudspeaker 

  • Guitar to Guitar Modeler to Mixer to Loudspeaker 


The Simplest Thing That Could Possibly Work Throughout this site, we talk about the simplest thing that could possibly work. Short version: Choosing the simplest, fastest solution that still has a realistic chance of achieving the desired outcome—without over‑engineering or adding unnecessary steps.

Longer explanation: This phrase is often used in technical troubleshooting, product support, and knowledge‑building environments to describe a problem‑solving strategy based on:

  1. Speed over perfection
  2. A viable solution—not guesswork
  3. Iterative troubleshooting
  4. Avoiding complexity unless necessary
