Even if you’re one of those people who never read manuals, all we ask is that you read this page now befor e you begin using the M-Series power amplifier . Y ou’ll be glad you did! IMPORT ANT : The amplifier draws its ventilation air in from the rear and out through the f[...]

6 M-Series M-Series 15. For quieter listening, it is preferable to adjust the amplifier’s gain controls rather than the source signal’s output level (unless you have the source’ s control all the way up!). Other Nuggets of Wisdom • For optimum sonic performance, the channel and main mix faders on your mixer should be set near the “U” ([...]

10 M-Series M-Series M-Series Features Front Panel Much of the front panel of the M-Series amplifiers is comprised of ventilation slots for expelling warm air from the inside of the amplifier . Be sure to leave space in front of the amplifier for proper ventilation to occur . 1 . G a i n C o n t ro l These knobs control the levels to the output [...]

11 Owner’ s Manual Owner’ s Manual 3 . P R O T E C T I nd ic a t o r If the PROTECT LEDs are on, the amplifier’ s output section has shut down. That, of course, means you won’t hear anything until you rectify the situation. Thr ee things can cause the PROTECT circuit to engage: 1. Powering up the amplifier . A built-in delay circuit saves[...]

12 M-Series M-Series Be Aware: If the OVER TEMP LED comes on fr e- quently , something is overworking the amplifier or it’ s not properly ventilated. Look at each of the “extreme conditions” described above and try to determine what is causing the amplifier to overheat. Refer to “Thermal Considerations” on page 16 or to the “T roubles[...]

The AMP MODE switch determi[...]

14 M-Series M-Series ing. The Thru jacks are wir ed straight from the XLR and TRS INPUT s — ther e is no electronic circuitry between — so the signal going into the amp is exactly the same as the signal coming out of the Thru jacks. Y ou can use the Thru jack as an input, if necessary , since it’s wir ed in parallel with the other input con- [...]

Connect the detachable linecord (included in the box with your M-Series amplifier) to the power receptacle, and plug the other end of the linecord into an AC outlet properly configured with the corr ect voltage for your part[...]

16 M-Series M-Series General Precautions and Considerations AC Power Considerations Be sure the amplifier is plugged into an outlet that is able to supply the correct voltage specified for your model. If the line voltage should drop below about 97% of the rated voltage, the amplifier will no longer be able to supply rated power . (It will contin[...]

17 Owner’ s Manual Owner’ s Manual AC Power Distribution In order to minimize ground loops, the safety grounds for all the outlets should be connected to a common (“star”) grounding point, and the distance between the outlets and the common grounding point should be as short as possible. If lighting is used in a show , it is preferable to p[...]

18 M-Series M-Series Unbalanced TS (tip-sleeve) signals can be accom- modated via the combination jack. Make sure the cord terminates with a TS plug (like a guitar plug), or if it’s a TRS plug (like a headphone plug), make sure the ring is tied to the shield, preferably at the source.

No, that’s not a typo. Y ou only use the red binding[...]

20 M-Series M-Series Dual-Channel Connection The Channel 1 Speakon connector has the added feature of providing both speaker outputs on a single connector . This allows you to use a single cable to carry both channels from the amplifier to the speakers. Refer to the hookup diagram on page 7 for a typical applica- tion using the dual-channel connec[...]
