Owner's Manual

1 Introduction
Thank you for your purchase of this Ashly CA
power amplifier. This product uses state of the
art, light weight, high power, high efficiency
switching technology developed through
years of design and testing. CA amplifiers are
available in three power levels, designed to
meet the most demanding live sound and fixed
installation sound systems in stadiums, arenas,
performance venues, worship spaces and
convention centers.

2 Requirements
Before connecting to AC mains power, make
sure that the mechanical installation, cooling
requirements, wiring, and controls are all set to
the configuration needed for your application.
Failure to do so could result in damage to the
unit or to other components in the system.
2.1 AC Mains
This amplifier uses a universal Switch Mode
Power Supply (SMPS) with active Power Factor
Correction (PFC). The power supply will auto-
detect nominal AC mains voltage from 100 to
240VAC, 50-60Hz.
Use only the provided AC cord to connect to AC
mains.
