MAIN FUNCTION: ♬ MA-S series power amplifier use particular THE MIRRORED FRONTED POWER SUPPLY BRIDGE to make the symmetrical circuitdesign. It can make more less distortion and better sound, but cost morehigher. ♬ With power auto switch system,power parallel connection in low power, increase the output current. And thevoltage will auto increase in big power to increase the output power. ♬ It have input power supply filter,make the capability of anti-jamming more strong. ♬ Amplifier circuit with shieldcover, add shield ring in transformer to make less noise, let the product havemore clear sound. ♬ Independence close cooling windpath to make the cooling more fast, even use for long time will be very clear. ♬ Have perfect protect function,power on amortize, delay connect speaker, limited function, over-currentprotect, overheat protect, short-cut protect and output DC protect etc. |

1、This amplifier is noise-free
When without output connect, the AODA amplifier have no noise evenit turns to the maximal volume. It will increase the quality of your work.
2、The amplifier has multiple wiseprotection systems built-in
The AODA amplifier integrate protect impactfunction of the power soft-start, DC output protect function, longtimeover-heat protect function, and turn on delay function. It can speedy protectthe circuit when the amplifier short circuit and over loading, and won’tintermit the performance.
3、The unit has built-in digitalcurrent limiter(crowbar)protection
Why some audio system always is broken thealt? It maybe isn’t the problem of alt, if you choose the wrong amplifier itwill also cause it. The smooth-top distortion of the amplifier not only causethe deterioration of sound, but also the killer of alt. The AODA amplifier usethe input/output comparative circuit. It will cut down the input signal whenthe amplifier going to the distortion state, so it can protect the speakersystem. This function have control by on switch, you can switch on/off to use itor not. It let you have more choice.
4、Excellent timbre
AODA amplifier have excellent and naturaltimbre either in frequency scan testing or engineering instance. It also havevery good control for the speaker. It have power from 2×400W to 2×1400W, can matchingany sound box.
5、The two dual-speed fans switchautomatically to maintain the proper internal operating temperature
AODA Amplifier have tunnel heat releasesystem, with high heat output. Every channel have separate winshield fitting,insure the heat can release in time and make the amplifier operating safely.
6、The unit has various input/outputconnectors
AODA amplifier has various input/outputconnectors, it have three way sensitivity switch for choose level, stereo,bridged-mono, and parallel mono. It can connect the speaker speedy by theprofessional SPEAKON.
7、The unit has consummate workingstatus indications including
You can be clear at a glance of the workingstatus through the LED indicator in the front panel of AODA amplifier, and letthe operation more easily.
