1. INTRODUCTION

Thank you for purchasing this 2-Zone Mixer, PMX 2300. Where there are zones, there you need a zone mixer.

This unit is custom designed to the user’s specifications. It offers you 3 outputs including 2 zones (stereo) and

1 utility (mono) and 5 inputs including 3 stereo line inputs, 1 paging microphone input and 1 emergency input.

This is very useful mixer for conference and dining facilities, such as hotels, convention centers, theaters,

auditoriums, restaurant, retail outlets, amusement parks, and even your home. All designs are for supplying

high quality and reliability to you. Enjoy it!

Please read this owner manual carefully, and look after it. If you ignore the manual and directly jump into the

different and check if you are familiar with the mixer.
