Page 3: Introduction
If the PSW-2 shuts down due to either low or high voltage, the power supply automatically turns on after three seconds if the voltage has returned to either normal operating range. -
Page 4: Current Requirements
Current Requirements The PSW-2 presents a dynamic load to the AC mains which causes the amount of current to fluctuate between quiet and loud operating levels. Since different types of cables and circuit breakers heat up (and trip) at varying... -
Page 5: Power Connector Wiring Conventions
For example, since the input impedance of a single PSW-2 is 10 k , cascading 20 PSW-2s brown = hot produces a balanced input impedance of 500 . If a 150... -

The PSW-2 operates safely if the Exc. Clamp LED is on for no longer than two seconds, and off for at least one second. -
Page 7: Rigging
Rigging The PSW-2 weighs 162 lb (73.5 kg). The maximum rec- ommended load for a single cabinet with aircraft pan fittings is 600 lb (273kg). This working load is based on a 5:1 safety factor. The PSW-2 has six rigging brackets (three on top and bottom). -
Page 8: Measurement And System Integration Tools
• The DS-2 & Sub Crossover switch (channels 1 and 2 only) activates a crossover network optimized for the DS-2P when used with the PSW-2 or 650-P. With the switch in, frequencies below 80 Hz are sent to the Sub output (for the 650-P), and above 80 Hz to the DS-2 output. - Page 9 Mid-Hi output also eliminates the LF rise caused by the overlap between the MSL-4 and PSW-2. Although a typical MSL-4 : PSW-2 ratio is 2:1, CH 1’s Sub and Mid- Hi level controls allow the ratio to vary while maintain- ing control of the spectral balance of the system.

Page 10: Driver Troubleshooting
Troubleshooting with TPL The TPL LED can indicate serious driver problems, if interpreted correctly. If one PSW-2 in a system exhibits substantially more TPL activity than others receiving the same audio signal, then one or both drivers in that unit may have a short circuit. -
Page 11: Safety Summary
English • To reduce the risk of electric shock, disconnect the loud- speaker 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 ground- ing mains receptacle. -
