The PSM-2 self-powered stage monitor contains i ndependent amplifier and control electronics for one 12” cone driver and one 4” diaphragm horn driver in a compact enclosure. This integrated design eliminates amplifier racks, improves durability and reliability, and simplifies setup and installation.
2 According to ISO/IEC Guide and EN 45014 The product herewith complies with the require- ments of the Low Voltage Directive 73/23/EEC and the EMC Directive 89/336/EEC.

4 AC Power The AC voltage operating ranges for the PSM-2 are 85–134 V and 165–264 V, at 50 or 60 Hz. The PSM-2 performs surge suppression for high voltage transients and can safely withstand voltages up to 275 VAC.
5 Differential Inputs Audio Input The PSM-2 presents a 10 k Ω input impedance to a three- pin XLR connector wired with the following convention: Pin 1 — 220 k Ω to chassis and earth ground (ESD .
6 Limiting and Protection Circuitry TruPower Limiting System Conventional limiters assume that the resistance of a speaker remains constant and set the limiting threshold by measuring voltage only.
7 The fans draw air in through ducts on the front of the cabinet, over the heatsinks, and out the rear of the cabinet. Since dust does not accumulate in the ampli fier circuitry, its life span is increased significantly. Make sure that the air ducts are clear and that there is at least 6” clearance for exhaust behind the cabinet.
8 PSM-2 and PSW-2 The PSM-2 can be used with the Meyer PSW-2, PSW-4, or 650-P self-powered subwoofers. However, due to the overlap of frequency response between the PSM-2 and th e subwoofer, the system frequency response exhibits a rise in the range 50–120 Hz.
9 • To reduce the risk of electric shock, disconnect the loudspeaker from the AC mains before installing audio cable. Reconnect the power cord only after making all signal connections. • Connect the loudspeaker to a two-pole, three wire grounding mains receptacle.
