美國美奇/美技MACKIE M800 專業(yè)音頻功率放大器
800W專業(yè)功率放大器:輸出功率:800W（4歐橋接）、550W（8歐橋接）400+400W（2歐）、275+275W（4歐）140+140W(8歐)
與其它的Mackie FR系列產(chǎn)品一樣，M800功率放大器擁有T-Design通道式散熱設(shè)計，兩個可變化的低切濾波器，為您的PA系統(tǒng)達到最大化的低音輸出提供了可靠保證。最為重要的一點是，M 800具有FR系列產(chǎn)品享譽盛名的快速恢復(fù)電路，其能夠阻止過量失真的發(fā)生。在不影響整體聲音電平的情況下，帶有On/Off開關(guān)的限制器可有效地減少失真。M800還配有一個高質(zhì)量的熱交換器，這就使輸出晶體管保持低溫變得易如反掌。該功率放大器結(jié)構(gòu)堅固，經(jīng)久耐用，可適用于各種音頻應(yīng)用。

Ultra-low-noise/ low-distortion design
Fast Recovery circuitry reduces distortion at the edge of clipping and beyond
Two 2nd order, 12dB/octave, Bessel low-cut filters with variable frequency from Off to 170Hz help optimize bass output of your sound system
Constant directivity horn EQ/Air EQ with variable frequency from 2k to 6kHz and on/off switch
Limiter with On/Off switch (decreases distortion that may become present when the M?800 is driven at max levels without affecting overall sound levels)
XLR thru outputs
1/4" jacks and 5-way binding post outputs
Detented gain controls calibrated in dB & volts
Signal present and OL LEDs
Channel Status LEDs
Easily handles 2-ohm loads all night long
Superior T-Design cooling
5-year transferrable Limited Warranty
