Product Overview
The TOA A-2240 mixer / power amplifier offers versatile features and outstanding value for installed sound applications such as schools, offices, restaurants, shops, factories, houses of worship and large meeting rooms. The A-2240 (240W) is manufactured with proven TOA quality and reliability.
Features include five inputs, two auxiliary (stereo summing) line inputs. two balanced microphone inputs and one telephone input. Mic 1 input provides 21VDC phantom power (switchable ON/OFF). Speaker outputs consist of 70.7V, 25V and 4Ω. An auxiliary line output can be used for recording or connection to an external power amplifier.
An Auto-Mute function provides voice-activated priority override for the Microphone and Telephone inputs which override the Auxiliary inputs. Auto-Mute sensitivity is adjustable for the Microphone and Telephone inputs. Other features include channel level, master volume controls and bass/treble controls.
The A-2240 is a high cost-performance mixer power amplifier suited for broadcasting paging or background music in schools, offices, shops, factories, mosques, churches and large rooms.
