DESCRIPTION
The TOA Model AX-1000A is an eight-channel automatic microphone mixer. Using TOA 900 Series modules for
flexibility and reliability, it has been specifically designed for commercial sound reinforcement applications.
Microphone inputs may be mixed with line-level inputs in any combination. Where potential feedback is of major
concern, the AX-1000A incorporates the technology required to gate on quietly, quickly and automatically. The
AX-1000A is equipped with channel logic outputs, channel direct outputs, priority-override channel muting and
Master/Slave linking for up to ten units.
Applications include:
•Churches
• Combinable function rooms
• Boardrooms
• Courtrooms
• Conference center systems
• Teleconferencing and multi-media rooms.

INTRODUCTION
The AX-1000A is an economical and very versatile mixer. This manual will help you understand how to include the
AX-1000A in highly engineered sound systems. If you are simply installing a single AX-1000A for microphone
mixing (with perhaps a line input for music), the procedure is very simple.
Basics are covered in Section 3~9:
3. Installation
4. Input Signal Flow
5. Input Connections
6. AX-1000A Configuration: Quick Setup
7. Output Connections
8. Operation: Setup Checklist
9. Setting Up Input Modules
You will also find TOA's Input Module Instruction Manual helpful. Most of the time, this is all you need to know to
specify and install the AX-1000A. An Installation and Setup Checklist has been included in the Appendix. Copy the
pages for a complete on-the-job reminder of setup operations.
Because of its rich feature set, an AX-1000A can be used in almost any commercial application. However, if you
progress beyond basic applications it is a requirement that you study this manual carefully. Using the AX-1000A's
