• Feature Model : AIYIMA A07 MAX Product name:A07 MAX TPA3255 Power Amplifier Stereo Max Output Power (switch stereo mode): 300Wx2 / 4Ω （48V/12A） Mono Max Output Power (switch mono mode): 600W/ 2Ω （48V/12A）(R+ connect to speaker +, L+ connect with speaker -) Working Voltage:DC24-48V,5A or moreReplaceable Op-Amp Chips:OPA2604AP, OPA2134, MUSEO1/02/03, LME49720NA, LM4562, AD827AQ, and so on AUX OUT: energetic nsubwoofer or energy amplifier three AUX OUT as output connect to next amplifier without volume management THD+N:0% SNR:≥110dB Input sensitivity:1V AUX Maximum Output level:1V Frequency response 20Hz-20KHz（±1dB） Package included: 1*A07 MAX Amplifier 1*User&;s Manual 1*Power Adapter(Optional)Q: All my cables are connected, yet there isn't any sound output? A: 1 Check if the machine has started and if the indicator light is on 2 Is the selection of mono/stereo mode and the relationship of the speaker interface right three If the above two elements are normal, verify whether or not the playback machine of the input sound supply is paused, muted, or the quantity is on the minimal Q: Why is the sound distorted? A: The input level may be too extensive If the quantity of the sound source kit is adjusted to the maximum, and the quantity of the machine also is adjusted to the maximum, it is easy to be distorted At this time, turn down the quantity of the sound source enter machine or machine Q: Why does the quantity of the mechanical device remain the same, but the sound level is varied when connecting to diversified audio sources (for example,connect a CD first, then a mobile phone)? A: The amplitude of electric signals output via different playback instruments is different For example, cellphones are usually 0, whereas CDs are 1V The pure sound size is various Q: Why does the horn emit a noisy electrical current sound or buzzing sound? A: 1 If you are not utilizing the original ordinary energy supply, please replace the flexibility delivery and test again energy materials in the market have interference, that will cause recent sound 2 When the sign line without shielding is used, there will be interference indicators coming into the flexibility amplifier for amplification It is recommended that you simply replace the sign line with shielding 3 There continues to be noise after troubleshooting the above two points,Please verify the noise is from the external or the inner Disconnect all inputs, only retain the ability supply and output cable, if the noise disappears, which means the noise is from the audio input If the noise remains to be there, the noise may be attributable to interference with the power delivery or generated inside the amplifier Q: Why there is no sound or little or no sound after the amplifier is connected to the speaker? A: 1 Please examine the audio source has been grew to become on and the volume isn't at the minimal 2 Please verify whether the speaker and amplifier event ( For example, the speaker is constant resistance or fixed voltage, the power of speaker is too a lot over the flexibility of the amplifier etc) Q: What are the reasons for the unbalanced left and appropriate volume of the audio system and how to get rid of them? A: Please check audio source, input cable, volume potentiometer (some amplifiers have balanced management or separate quantity management of left and correct channel ), speaker cable, speakers (whether the placement and the space is symmetrical) and different factors Q: Why is there a thumping sound when swithing on/off? A: Please verify the on-off series is correct, normally it follows the order of signal transmission when turn on: audio source → preamp / DAC → amplifier → speaker (The series is reversed when switching off As the internal capacitors could be discharged for a whereas after shutdown If flip off the preamp firstly and then flip off amplifier, impact sound may be easily brought about which may harm the amplifier or speaker in severe cases)
