4 AC Power The AC voltage operating ranges for the PSM-2 are85–134 V and 165–264 V, at 50 or 60 Hz. The PSM-2performs surge suppression for high voltage transientsand can safely withstand voltages up to 275 VAC. Continuous voltages above 275 VAC may damage the unit! When an AC source is applied to t...

6 Limiting and ProtectionCircuitry TruPower Limiting System Conventional limiters assume that the resistance of aspeaker remains constant and set the limiting thresholdby measuring voltage only. This method is inaccuratebecause the speaker’s resistance changes in responseto the frequency content of ...

Page 7 - Example Applications

7 The fans draw air in through ducts on the front of thecabinet, over the heatsinks, and out the rear of thecabinet. Since dust does not accumulate in the amplifiercircuitry, its life span is increased significantly. Makesure that the air ducts are clear and that there is atleast 6” clearance for ex...

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 theoverlap of frequency response between the PSM-2 andthe subwoofer, the system frequency response exhibits arise in the range 50–120 Hz. The rise can be eliminatedby the Meyer CP-10...

Page 9 - Safety Summary

9 • To reduce the risk of electric shock, disconnect the loudspeaker from the AC mains before installing audiocable. Reconnect the power cord only after making allsignal connections. • Connect the loudspeaker to a two-pole, three wire grounding mains receptacle. The receptacle must beconnected to a ...
