Operation

MP Seri es amplifier power requirements are rated at: a) "idle" b) 1/8th po wer ("t ypical" music c ond itions) c) 1/3rd po wer ("c ontinuous" music c onditions) d.) maxim um rated power ( under limited) . The maxim um power curre nt draw rating is l imi ted only by the rear circuit breaker(3U MO DEL) or the fuse type (2U MO DEL) . Consult the spe cifications sect ion for figure s on the current that each a mplifier will demand. M ake sure the mains volta ge is c orrec t and is the same as th at pr inted on the rear of the ampli fie r. Damage ca used by connecting t he amplifier to improper AC vol tag e is not covered by any warr ant y. Unless ot herwise specifie d when ordered, DynaTech amplifi ers shipped to custo mers are configured as follow s:

North America 120VAC / 60Hz Europe 230VAC / 50Hz Asia 220VAC / 50H z Austral asia 240VAC / 50Hz South America 120VAC / 60Hz or 220 VAC / 50 Hz Japan 100 VAC / 50Hz

NOTE: Always turn off and dis connect the amplif ier from mains volta ge before makin g aud io connection s. Also, as an e xtra precaution, h ave the attenua tor s turned down during p ower-up.

Operation

Connecting Power / Circuit Size Requirements.

Cooling System and Requirements.

Use eithe r th e XLR o r 1/ 4-i nch input conne cto rs on the rear to supply audio sign als to your DynaTech MP Series am plifier. Both connector s accept balanced an d unbalanced audio c onnections. (The M P Series amplifi ers are c onfigured standard w ith " Pin 2 hot" on XLR inp uts . Please note tha t som e other Audio amplifi ers are c onfigured with "Pin 3 ho t") . Th e unused connector can be use d to jumper the audio inpu t to anothe r am pli fier in put.

Connecting Inputs.

Speaker s are con nected using Ou tpu t Binding Posts o r Speak on co nnectors, For more informat ion, see the Mode Sele ction sections.

Connecting Outputs.

Connect ing amplifier o utp uts to oscillos cop es or other test eq uip ment while the amplifi er is in bridged mo de ma y damage both the a mpl ifier and test eq uip ment!

MP Seri es amplifiers use a tw in-tunnel forced-a ir cool ing system to mainta in a low, even opera ting temperature. Drawn o ut by d ual 45 cubic feet -pe r-minut e (CFM) fans on the rear panel, air flows from the fron t gri ll and through the co oling fins of the chan nel heat sinks (diss ipating power transi sto r he at), then exhausts t hrough the ba ck panel ports. The "intell igent" variab le- speed DC fans are controlled by h eat sink temperatu re sensing c ircui ts. Whe n the amplifier is turne d on, the fans briefly " re v up, " then slow to an idle; th is indicates that the te mperature sensing ci rcuit s are ope rating normally. The fa n speed increases only a s requi red by heat sink t emperatures, keepi ng fa n noise to a minimu m. Un der ext re me thermal load, the f ans will force a very larg e volume of air through the heat si nks . If either heat sink surp asses the maximum al lowed temperature, the se nsi ng circ uit will shut dow n the o utput, no signa l out put to the load . If th e pow er tran sformer overhea ts, another sensing ci rcuit s hut d own both channe l out put until the tra nsf ormer cools to a safe temp erature.

IMPORTANT: To ens ure o ptimum coolin g, periodically cl ean the amplifi er fa n filters. Also make certa in th at there is en ough space around th e back of the amplifie r to allow the cool ing a ir to escape. If th e amp lifier s rack-mo unted, do not use door s or covers on the front o f the rack, the exhaus t air must flow out with out resista nce. If the amplifie rs are to be housed in rac ks with closed ba cks , allow at least on e (1) s tandard rack space of op ening in the front of th e rack for every four am plifiers.

The three-positi on, rec essed Mode Select sw itch (located on the rea r panel ) con figures the amplifie r fo r either Stereo, Par allel or Bridged Mono Mo de. Amplifiers a re fact ory -configured for Stereo Mode.

Stereo Mode.

In Stereo Mod e, bo th channels operat e independent ly, with their input atte nua tors controlling the ir respectiv e lev els. Signal at Ch ann el 1's input produces ou tpu t at Channel 1's ou tpu t, while signal a t Channel 2 's input produces output at C hannel 2's output. R ecommended minim um nominal load impedan ce for st ereo op eration is 2 ohms p er chan nel. Either the 1/4" (TR S) in puts or the XLR inputs may be used .

Parallel (Mono)Mode.

When set to Par all el(Mono) Mode , Th e sig nal input to Chan nel 1 a nd channel 2 will b e add ed together and be ampl ified and appear at outputs f or both C hannels 1 & 2. The output si gna l is controlled by each

attenua tor

NOTE!: So me other amplifier s only use Channel 1 for i nput, and both outpu t is controlled b y Cha nnel 1 attenua tor .

Bridged Mono Mode.

Bridged M ono Mode straps both a mplifier channels to get her to make a very powerfu l, single-channe l monaura l amplifier. One channel "p ush es" and the other "pulls " equally, doubl ing the power over that of either chan nel a lone. Signal is a ppl ied to the Channe l 1 inp ut only, both o utp ut level is controlled b y Cha nnel 1`s att enuator .

NOTE: The c hannel 2 input conne ctors (XLR and/or TR S) may be used to "lo op th ru" the channel 1 s ign al when in par allel or bridged mon o mode. Use extre me caution when oper ating the ampli fie r in Bridged Mono M ode . Never ground ei the r side of the speaker c able when the amplif ier is in Bridged M ono M ode; both sides a re "h ot." If an output p atc h panel is used, al l connections must b e isolated from e ach o ther and from the p ane l. The recommen ded m inimum nominal l oad impedance i n the B ridged Mono Mod e is 4 oh ms, which is the eq uiv alent to drivin g bot h channel s separately at 2 ohms . Driving bridged lo ads of less than th e rec ommended mini mum s will activate the IGM cir cuitry, r esu lting in a loss of po wer, and may also le ad to a thermal protec t condition.

Subwoofer Mode This mode s ends low frequencies t o you r sp eak ers without the u se of a n external cross-ove r. The subwoof er

operati on can be operated in st ereo, m ono, or bridge mono mode s. Ch ange the different ope rating modes by flippin g the mode switch on the rea r of the un it to y our desired operating mode. Also, set the subwo ofer mo de switch to t he subwoofer position. Us e the fre quency select or to adj ust the subwoofer output freq uen cy from 20Hz to 200 Hz. The d ifferent subwoofer modes are li ste d as follows:

Bridge Subwoofer - This op era tion allows you t o get t he most possibl e pow er out of your amplifier for

the sole pu rpose of running a hig h powered subwoofer loudspe ake r in m ono . To avoid am pli fier overheating, never run the a mpl ifier below 4 ohms in this m ode . In this mode you ma y use t he frequency adjustm ent on the rear of the amp, to co ntrol t he freq uency output level . Frequ encies may bead jus ted from 20Hz to 200Hz. Page 12 det ails a typical Bridg e Subwoofer set up.

Stereo Subwoofer - This oper ati on is similar to the Bridg e Subwoofer operatio n but i n stere o. This operati on allows you to run sev eral subwoofers do wn to a minimum of 2 ohms. To avoid amplif ier ove rheating , never run the amplifie r below 2 o hms i n this mode. Set up t his m ode as you would a st and ard stereo

set up. Be su re both c hannels are set to ※SUBWO OF.§ In this mo de you may use the frequency ad justment on the rear of the amp, to c ont ro l the bass frequency output l evel. Frequencies ma y be ad justed from 20Hz to 200Hz. P age 10 details a typic al Stereo Subwoofer set up.

Parallel (Mono) Subwoofer - This opera tio n is similar to the Stereo Sub woo fer ope ration but in mon o.

When runn ing subwoofers it is u sually recommended t o run t hem in mono mode to a chi eve a cleaner tighter low end. This o per ation allows yo u to ru n several subwo ofe rs down to a minimu m of 2 oh ms. To avoid amp lifier oveheat ing, never run the ampli fie r be low 2 ohms in this mode. S et up t his mode as you wou ld a st andard stereo

set up. Be su re both c hannels are set to ※SUBWO OF§ an d the mode switch i s set t o ※MONO.§ In this mod e you may use t he freq uency adjustment o n the rea r of t he amp, to control the bass frequ enc y output level. Frequenci es ma y be adjusted from 20Hz to 2 00H z.

One Channel Normal/One Channel Subwoofer (BI-AMP) - You may also use your amp to bi-amp yo ur syst em. You may use one side of the a mp to power a subwoofer and the other side t o pow er a full rang e speaker. See figures o n pag es 10 - 12 showing outpu t connection in for mation.

Protection

The MP seri es co mes with a built- in li miter. When th e input signal ov erl oads, the “CLIP LE D’s” indi cate a signal ov erload, at this time , the master volume shou ld be l owered to reduce distortion . If the input gain leve l is not reduce d the b uilt-in limit er will a ctivate. During si gnal overload, the l imiter will reduce the input au dio signal en ough to minimize the a mount of clipping. A limiter takes the g ain o f an overloadin g sig nal and reduces it, the reduc tio n in gain reduces distor tion that can cause da mag e to your speakers and amp lifier. Du ring normal op eration below clip ping, and momentar y clips on peaks, the li miter does not affect th e aud io signal and is inau dible. It will allow b rief clipping o f pea ks and will only activ ate when contin uou s, hard clippin g occurs. D uring excessive cl ipping the limi ter wil l reduc e the audio signal eno ugh to minimize the am ount of clippin g. When t he input signal d ecrea ses e nough that clip pin g ends, the limit er will d eactivate and ceas e its gain reduct ion . Th e lim iter has a fixed threshold a nd ca n not be adjusted.

8-Ohm Loa ds: The a mplifier can operate a t pra ctically any po wer lev el without risk o f ove rheating. How eve r, if it is push ed hard enough to cont inually light the “C LIP” indicator, the ampli fier’s average outpu t pow er can reach 150 w att s. 4-Ohm Loa ds: If the “CLIP” indi cator flashes occasi ona lly, the ampl ifi er is app ro aching its maximum long-te rm power capacity. If it is l it about half the t ime , the amplifier channe l will probably go into th erm al protectio n wit hin a few minutes . 2-Ohm Loa ds: Except for an occasi ona l flash, keep the “ CLI P” indicator dark to avo id ov erheating the amplifi er chan nel. Clipping s hou ld be kept to a reasonable m ini mum. An ampli fie r’ s peak current draw a t full outp ut power into 2 ohms is several t imes what the “no rma l” draw is, but its v ari ous pro tection circuits wi ll prev ent t his condition l ast ing more than a minute or two.

Safe Power Levels at Different Output Loads

The MP seri es am plifiers all co me wi th built-in Out put S hort Circuit Protects. The Outp ut Sh ort Circuit Protecti on prot ects the output devi ces of the amplifier from short c ircui ts and stressful loads . If yo ur speaker lin es sh ort, the amplif ier aut oma tically detec ts this problem and discont inues operation fo r th at channel . If one side of your amplif ier bec ome s shorted and goe s int o protect mode, the othe r si de wi ll continue to operat e normally. Duri ng short circuit protection , the “Clip” LED will li ght simultaneous ly indicating amplifi er faul t. The ch annel output du rin g the “Short Circuit Prote cti on” will be inter rup ted (i.e. no soun d output) S hort Circuit Protection can u sua lly be traced bac k to th e signal output l ine ( i.e. speaker line). Ch eck the line from t he ou tput terminal o f the a mplifier to the speake r. If thi s lin e good, check the i nte rnal speaker connect ions and component s. A short ci rcuit w ill u sually be trace d to a ba d cable or a bad speaker compo nen t and is rarely t rac ed to the amplifi er itse lf.

Short Circuit Protection

Thermal Protection

The input circuits a re isol ated by 10k resistors. An ultrasonic networ k uncouples RF fro m the output and helps kee p the amplifier stable w ith rea ctive loads.

Input/Output Protection

Dual vari able speed fans on the M P series amplifi er provid e adequate cooling . During low level out put the fans run at n ormal speeds. Duri ng high output and as he at raises, (exceed ing 50° C), the fans wil l run at higher spee ds to a id the cooling process . If th e heatsink temp era ture exceeds 91° C, the am plifier will mute until the a mplifier cools down. When the a mpl ifier cools below 90º C, t he amplifier will return to nor mal operati ons. Be sure not to operat e you r am pli fier below the minimum l oad ratings to reduce th e ris k of overhea ting problems.

The AC main volt age is printed on t he ba ck where the AC power input . Con nec ting to the wrong voltag e is dangerou s and m ay damage the amplif ier. Always be sure the source volta ge fo r yo ur areas match es the required voltage f or your amplif ier.
