Introduction

It is always advisable to power up equipment in sequence, orderly manner ie.  from mixer to power amplifiers and vice versa. This is to prevent power surge, and in long term prolonging the lifespan of the equipment.

SQ9815 is a 8 channel ac powering unit making switching on or off simpler by push of a button. Two units can be link to form a 16 channel setup.

Introduction

PS9400 is a rack mounted 24V DC regulated power supply with built in mains failure changeover relay. This allows battery to continue supplying the critical equipment during power failures, ensuring continuous operation of the system.

Only regulated power supply should be used in PA installation, as unregulated types may produce voltages unsuitable for powering the equipment upon fluctuation of incoming mains.
