[. . . ] Do not block or cover the heat sink from ventilation. Be sure to keep the microphone away from the front of the speaker after switching the mic sensitivity pad to the OUT position and while setting the microphone level or very loud feedback will occur!Damage to the system is likely if this occurs!DO NOT connect the inputs of the PRTM15P to the output of a power amplifier. The inputs are meant to be driven from a line-level strength signal. DO NOT remove the protective metal grille. Warning: The FORUM AX is very efficient and powerful!This sound system can permanently damage hearing!Use extreme care setting the overall maximum loudness!The apparent sound level of the FORUM AX can be deceiving due to its clear, clean sound output. The lack of distortion or obvious distress can make the sound level seem much lower than it actually is. The unit is shipped with the tab in the line-level position. It is recessed behind the panel so that the gain can not be inadvertently increased during transport or set-up. Due to the 30 dB of extra gain that this switch provides, DO NOT leave it in the "out" position for line level use!This will result in input-stage clipping of the FORUM AX and cause unnecessary distortion. Mixing Signals Using the Volume Knobs The gain of all three channels can be adjusted independently from the other channels via the volume knobs (7) and (9). Channel 1 can be used for either line-level signals or as a mic input, and mixed with two other line-level signals. The FORUM AX has plenty of gain, so do not overload the speaker system preamp inputs by driving them with a signal that is too hot. Full output mixer levels well in excess of 0 dB will not going to be necessary to drive the unit to full power capacity. TROUBLESHOOTING No Output at All First, make sure the unit has AC power and is turned ON. Make sure the Power/Clip LED (4) is illuminated Green. If not, make certain the ON/OFF switch (3) is in the ON position and check the IEC power cord connection (2) by ensuring it is fully engaged and seated. Make certain the AC line cord is plugged into a working AC outlet. (See the Rear Panel: Fuse section, for safety instructions. ) Once assured your unit is getting AC power, check that the FORUM AX is getting a signal. [. . . ] Electronic Input Impedance (Nominal): 10 k Ohms unbalanced, 20 k Ohms balanced line level, 2. 4 k Ohms balanced mic level. Input Connections: One combo female XLR/ 1/4" phone jack providing balanced operation, with switch selectable mic or line level sensitivity. Also has two 1/4" phone jack line level unbalanced inputs with a concentric pair of level controls. Enclosure Materials and Finish: Injection-molded polypropylene of a nominal thickness of 1/4" with internal ribbing and bracing, and with textured finish. [. . . ]
