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.
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).
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.

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.
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.
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.
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.
25 10 Hz 1 Hz 100 Hz 1k Hz 10k Hz 20 k –15 dB –10 dB –5 dB 0 dB 5 dB LC F i l Level, dB Fre q uenc y , Hz In order to match the output bandwidth with your particular speaker system, the M•2600 amplifier has a tunable LOW CUT FIL TER .
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.
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.
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 .
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.
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.
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 .
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.
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.
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).
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 .
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.
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.
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 .
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.
