Features
The A-2000D Series is a range of high performance mixer power amplifiers suited for broadcasting paging or background music in houses of worship, schools, offices, shops and factories. Equipped with balanced microphone inputs for better isolation from external noise, compared to unbalanced inputs, the A-2000D Series is suitable for AC operation and comes with power outputs from 30 W to 240 W. It is finished with a scratch and fingerprint-resistant surface for easy handling as well as quick volume control with master volume knob.
FEATURES
Wide range of power outputs from 30W to 240W
3 microphone inputs, 2 AUX input and 1 recording output
Speaker output of constant voltage distribution system (100 V)
Independent tone control of boost and cut type for both high and low frequency
MIC 1 with phantom power and mute function
Current limiter to prevent damage due to current overload
Excess heat limit to protect the transistor and power transformer
Finished with a scratch and fingerprint-resistant surface for easy handling
Use MB25B (sold seperately) for rackmounting.
Note this is the new Class D model with the following differences over the analogue models;
VOX muting on mic 1
High (100V line) output only – no low impedance output
240VAC operation only

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 (240 W) 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 21V DC phantom power (switchable ON/OFF). Speaker outputs consist of 70.7 V, 25 V and 4 ohm. 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. Suggested TOA Paging Microphones include: PM-222U, PM-660U or PM-20EV The A-2240 is not rated for rack mounting applications.
