Technical specs: It runs on 120 V AC, has a 240 W rated output, and specific power consumption details. With a frequency response of 50 - 20,000 Hz (-3 dB), low distortion of 1% or less at 1 kHz and 1/3 rated power. Inputs and outputs are clearly defined with specific impedance and connection types. It also has a 60 dB or more S/N ratio, tone control features, and a muting function. The panel is made of ABS resin in black, and the case is a steel plate in black. It measures 420 (W) x 100.9 (H) x 360.3 (D) mm and weighs 15.5 kg.
Using the TOA Electronics A - 2240 240W Mixer Power Amplifier is easy. First, make sure to connect it to a 120V AC power source. Then, connect your audio sources to the appropriate inputs. For microphones, use the balanced microphone inputs and switch on the 21V DC phantom power for Mic 1 if needed. Connect your speakers to the speaker outputs according to their impedance requirements. You can also use the auxiliary line output for recording or to connect to another amplifier. When using the muting function, note that MIC 1, MIC 2, and TEL can attenuate AUX1 and AUX 2 input signals. Adjust the sensitivity levels as you like. As for maintenance, keep the amplifier in a dry and cool place. Regularly check the connections to make sure they are secure. Clean the panel and case with a soft, dry cloth. Avoid exposing it to extreme temperatures or humidity, and don't overload the amplifier beyond its rated output.
