Kapatid,all these amplifiers will suit your JBL speaker.Period.....but!I think your question should be "how well this power amplifier you're considering will work well with your loudspeakers?"(remember,you got your JBL already).Simple:Borrow the amplifier from your dealer(downpayment pls.)for the weekend or if its available both on the store,listen to it.This is the best way of not only assessing its musical qualities,but determining how well it drives your loudspeakers.In addition,listening to the power amplifier at home will let you hear if the product's sonic signature(tunog lata yata ah?)complements the rest of your system.Finally, you could bring your loudspeakers into the store for a final audition.
Here's some pointers to remember in assessing sonic and musical characteristics of the chosen power amplifier.The first thing to listen for is whether the amplifier is driving the loudspeakers adequately.The most obvious indicator is bass performance.If the bass is soggy(malamya tumunog),slow (reduced sa pace,rhythm and timing),lacks punch(inde solid or buo ang bigay)the amplifier probably isn't up to the job of driving your loudspeakers.Other telltale signs that the amplifier is running out of current(kinakapos) include loss of dynamics(inde kayang kayang ibigay yung low and high demand ng music),a sense of strain on musical peak(pumipiyok ang tunog kapag high ang demand ng music),hardening of timbre(inde mona marecognise yung definitions ng performance,mapa vocal or instruments kapag nasa peak ang demand ng music),and congestion(kagulo na yung tunog,meaning walang definitions yung bawat instrument).
Pano mo sya susubukan?First, play (gig's out dude) at a moderate volume.Select music with a dynamic range-loud climax accompanied by bass drum,or music with a powerful rhythmic drive from bass guitar and kick drum working drum together(Yeah!).
Eh di tapos nasa sa mahina(painit lang to be become used to the sound at a moderate level),eto na,increase-the volume-you want to push the amplifier to find its limits.Etong tanong, does the bass seem to give-out(bumibigay/kinakapos?)when you turn it up,or does the amplifier keep on delivering?(mararamdaman mo yan).Listen to the dynamic impact of kick drum.Its should maintain its tigthness,punch,quickness at high volume level.If it start to sound soggy,slow,or loses its power,you're gone beyond the amplifier's comfortable operating point.After a while,you can get a feel for when amplifier get into trouble.Is the sound strained(hirap),or effortless?(o kayang-kaya?).An excellent power amplifier produce a sense of ease;lack of power often creates listeners fatigue.All the problem described are largely the result of the amplifiers running out of current.Bakit nangyayari to?Minsan sa design mismo ng amplifier's output power,its ability to deliver current into the loudspeaker,sa loudspeaker sensitivity rin(mas mababa,mas need ng power),sa impedance din(2ohms(kalbaryo sa amplifier),4ohms(pasaway),8ohms(Pwedeeeeeeee...cool!).,room size(mas malaki,pakilakas naman oh),at eto, how loudly you expect your band to play.Even when not pushed to maximum output, a more powerful amplifier will often have a greater sense of ease,grace,and dynamics than a less powerful amplifier.
Ba't mahaba? Remember,kahit anong galing mong tumugtog kapag ang gamit mo me weaknesses,from mic,cables,preamp,mixer,effects hanggang sa amplifier,up to the last chain,the loudspeakers,sayang lang dude!Your equipment's is your PERFORMANCE extension.
Teka lang,PAALALA!!!WHEN PERFORMING THIS GIG"S TEST,BE SURE NOT TO OVERDRIVE YOUR LOUDSPEAKERS.TURN DOWN THE VOLUME AT THE FIRST SIGN OF LOUDSPEAKER OVERLOAD(DISTORTION OR A POPPING SOUND.)
