Phase5 Public Address Amplifier 2x125W

Manufactured in Australia to stringent engineering criteria, the Phase 5 amplifier series exhibit quite remarkable performance and outstanding reliability. Over 2 years in design and development, the evolution of Phase 5 included extensive consultation and input from pro sound contractors and installers across the country. The host of features incorporated commend this amplifier series to the most demanding of pro sound and industrial PA system applications. Redback Phase 5 amplifiers incorporate on demand multi-staged thermally cued fan forced cooling.

The output power stage is thermally monitored enabling automatic operation of a long life computer style cooling fan to “off” or “on” air flow through a specially designed tunnel heatsink. In quiescent or ordinary cycle paging mode the fan is inoperative. Over temperature sensing is employed to shut down the amplifier in extreme over heat conditions, eg extreme over load and /or over drive misuse. Re-start is automatic once normal temperatures are attained. Output peak limiting.

The output voltage is limited to 105V maximum RMS voltage irrespective of load impedance to prevent damage to speaker load. Standard 100V line PA amplifiers can deliver up to 180 volts or more under conditions of high drive and very light loading. This output over voltage can quickly destroy any loudspeakers connected.
