17 feature 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 are 20 built-in “resting points” so you can easily set both controls to the same level. Usually, these controls are set ...
18 you may wonder why we didn’t use just one stereo control to control both sides. That’s in case your applica- tion requires a left/right imbalance (due to an irregu- larly shaped room) or if you’re using the two sides for completely different purposes (moni- tor in channel 1 and side-fill in chann...
19 short if this led comes on, the m•2600 has de- tected a short circuit in either of the outputs, meaning that the positive (+) and negative (–) speaker wires are touching, or a speaker itself is shorted out. Such a condition causes the m•2600 to engage its protect mode (when a signal is present), ...

21 what’s that? Why doesn’t the fan just go fast all the time? Well, if it did, you might actu- ally hear it whirring during your quiet moments (there are quiet moments in your life, aren’t there?). While this whirring would be of no concern in most live-sound situations, it could become annoying in...
22 speaker outputs the binding posts provide a secure and safe connection for bare speaker wire. To 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...
23 ordinarily, applying a positive voltage to a speaker’s positive input and negative voltage to the negative input results in an outward excursion of the woofer. But some woofers are built with reverse polarity, meaning that the above conditions result in an inward excursion. If you’re not sure whi...
24 you 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, refer to the “connectors” section (appendix b) at the back of this manual for more information. The m•2600 amp...

26 stereo mode (separate left and right inputs, separate left and right outputs) is the typical setup for amplifying stereo 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 ga...

This switch allows you to choose between three different configurations: limiter on (typical). This is the normal configuration: full-bandwidth audio with protective limiting. Limiter of...
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- ove...
29 general precautions and considerations g nema 5-20p (plug supplied with 120 vac models) ac power considerations 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 ...
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 more peak output power will be available for cleaner, punchier bass. A suspected pro...
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. Develop...
32 appendix a: service info • if the output application switch is set to low out (subwoofer), make sure the low cut filter 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?...
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. • can the amp breathe?

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.

Doing so is an invitation for a ground loop to come a-courting. 3. Do ensure that your speaker lines and ac power lines ...
37 10. Walk 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. You can get this information by calling the station. Remember that many broadcast stations change ...
38 biamplified and triamplified systems use separate power amplifiers to power each indi- vidual low-frequency and high-frequency 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...
39 appendix d: technical 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.
