Individuals vary considerably in susceptibility to noise- induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time.

17 FEA TURE DESCRIPTIONS GAIN These front panel knobs allow you to control the levels going into the output section of the M•2600 amplifier . Their travel is detented, meaning there ar e 20 built-in “r esting points” so you can easily set both controls to the same level. Usu all y , the se c ont rol s are s et to maximum. The gain structure o[...]

18 Y ou may wonder why we didn’t use just one ster eo control to control both sides. That’s in case your applica- tion requir es a left/right imbalance (due to an irr egu- larly shaped room) or if you’r e using the two sides for completely differ ent purposes (moni- tor in channel 1 and side-fill in channel 2, for instance). Besides, they loo[...]

19 SHOR T If this LED comes on, the M•2600 has de- tected a short circuit in either of the outputs, meani ng tha t the positive (+) an d negative (–) speaker wi re s a re t ouching, or a speaker itself is shorted out. Such a condition causes the M•2600 to engage its PROTECT mode (when a signal is present), muting all signals at the amp’s ou[...]

21 What’s that? Why doesn’t the fan just go fast all the time? W ell, if it did, you might actu- ally hear it whirring during your quiet moments (there are quiet moments in your life, aren’t ther e?). While this whirring would be of no concern in most live-sound situations, it could become annoying in a control room environment. So, when the [...]

22 SPEAKER OUTPUTS The binding posts provide a secur e and safe connection for bare speaker wir e. T o use the binding post outputs, unscrew them enough to reveal the holes on their sides, then insert your stripped wires (stripped about 3/8" back) into the holes and retighten the posts (finger tight is fine — please don’t reef on them with[...]

23 Ordinarily , applying a positive voltage to a speaker’s positive input and negative voltage to the negative input r esults in an outward excursion of the woofer . B ut some woofers ar e built with reverse polarity , meaning that the above conditions result in an inward excursion. If you’re not sur e which type of speakers you have, take a lo[...]

24 Y ou can connect an unbalanced XLR cable to the M•2600, although this would be unusual — as unusual as an unbalanced XLR output. However , if you have an unbalanced XLR connection to make, r efer to the “Connectors” section ( Appendix B ) at the back of this manual for more information. The M•2600 amp expects to see a nominal signal le[...]

26 STEREO mode (separate left and right inputs, separate left and right outputs) is the typical setup for amplifying ster eo signals. MONO mode (sometimes called Dual- Mono — one or two inputs, two mono outputs) is for sending a mono signal to two different speaker sets, with separately-adjustable GAIN controls. BRIDGED mode (sometimes called Bri[...]

27 OUTPUT APPLICA TION SWITCH The OUTPUT APPLICA TION switch should be configured befor e you turn on the amplifier . This switch allows you to choose between thr ee different configurations: LIMITER ON (TYPICAL) . This is the normal configuration: full-bandwidth audio with protective limiting. LIMITER OFF is also full bandwidth audio, but wit hou [...]

28 LOW OUT (SUBWOOFER) Here’ s a special surprise: If you bought the M•2600 amplifier to power a subwoofer system, you just saved yourself the cost of a crossover! The M•2600 amp has an active crossover built in. The amplifier can play the frequencies below the crossover point set with the CROSS- OVER switch . 20 Hz 100 Hz 1k Hz 10k Hz 20k Hz[...]

29 GENERAL PRECAUTIONS AND CONSIDERA TIONS G NEMA 5-20P (Plug supplied with 120 V AC models) AC POWER CONSIDERA TIONS Be sure the M•2600 is plugged into an outlet that is able to supply the correct voltage speci- fied for your model. If the voltage should drop below 97% of the line voltage, the M•2600 will no longer be able to supply rated powe[...]

30 It is recommended that a stiff supply of AC power be used because the amplifier places high current demands on the AC line. The more power that is available on the line, the louder the amplifier will play and the mor e peak output power will be available for cleaner , punchier bass. A suspected problem of “poor bass perfor- mance” is often c[...]

31 70V DISTRIBUTION SYSTEMS A distributed sound system uses a constant- voltage, high-impedance network that feeds a number of tapped transformers which, in turn, deliver power to individual speakers. Each tap is rated in watts, so you can select the amount of power delivered to the speaker . Developed for distributed paging and public addr ess sys[...]

32 APPENDIX A: Ser vice Info • If the OUTPUT APPLICA TION switch is se t to LOW OUT ( SUBWOOFER) , make sure the LO W CUT FIL TER frequency control is set to OFF or nearly OFF . If it is turned up above the subwoofer cutoff frequency , the output from the amplifier will be diminished. • Is the SHORT LED lit? T urn the POWER off, check the speak[...]

33 As soon as the music gets loud, the amp shuts down! • Check the M•2600’s meters. Be sure that OL is not lighting up frequently or continuously . • C an the amp breathe? The M•2600 amps draw their ventilation air in from the fr o nt and out through the side panels. They need plenty of fresh air to stay cool. Do not block the ventilation[...]

34 APPENDIX B: Connectors (output from mixer), ring to signal r eturn (in put back into mixer), and sleeve to ground (earth). • Balanced mono circuits. When wir ed as a balanced connector , a 1⁄4" TRS jack or plug is connected tip to signal high (hot), ring to sig- nal low (cold), and sleeve to ground (earth). This is the application used [...]

35 SPEAKONS Speakon ® connectors have become popular with many loudspeaker manufacturers be- cause they provide a quick, yet safe and secure method of connecting speaker cables. The con- nectors have a twist-locking mechanism that prevents them from being pulled out acciden- tally . Plus, they are capable of handling high currents and meet IEC 65 [...]

36 connects to pin 1) to prevent it from contacting the connector shell. 2. Don’t connect the XLR connector shell to pin 1 of the XLR connector unless necessary for RFI shielding. Doing so is an invitation for a ground loop to come a-courting. 3. Do ensur e that your speaker lines and AC power lines are physically separated from your microphone l[...]

37 10. W alk outside — look at the horizon. See any radio towers? Locate potential sources of RF interference and plan for them before you begin construction. Know the frequency , transmitter power , etc. Y ou can get this information by calling the station. Remember that many broadcast stations change the antenna coverage pattern and transmitter[...]

38 Biamplified and triamplified systems use separate power amplifiers to power each indi- vidual low-frequency and high-fr equency driver . An electronic crossover (a.k.a. active crossover) is located between the signal source and the power amplifier . The advantages of this method include: • Increased headroom available from each amplifier , sin[...]

39 APPENDIX D: T echnical Info “Parallel” means that the positive amp out- put connects to the positive terminals of all the speakers, and the negative amp output con- nects to the negative terminals of all the speakers. If one speaker fails in a parallel con- figuration, the others will still work, but the load will change. That lets you breat[...]
