The most widely recognized and trusted name in AC power conditioning is proud to introduce the PS-PRO II power conditioner / sequencer, featuring Furman's revolutionary SMP technology. Furman's Series Multi-Stage Protection (SMP) circuit also features our exclusive Linear Filter Technology (LiFT) coupled with Extreme Voltage Shutdown (EVS) and a high current TVZ-MOVs. Together, these technologies comprise what is, without question, the world's most advanced and comprehensive transient voltage surge suppressor.

SMP (Series Multi-Stage Protection Plus)
Furmanís SMP surge suppression virtually eliminates service calls. Traditional surge suppression circuits sacrifice themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your system, and repair of your surge suppressor. Not so with SMP. With Furmanís SMP, damaging transient voltages are safely absorbed, clamped and dissipated - no sacrificed parts, no service calls, no down time.

Unique to Furmanís SMP is its unparalleled clamping voltage, even when tested beyond the grueling specifications of - USA/CIDAís A-1-1 test. While other designs offer clamping voltages that are well above 300VAC peak (far beyond long accepted professional standards), Furmanís SMP clamps at 188VAC peak, 133 VAC RMS even when tested with multiple 6000VAC - 3000 Amp surges! This unprecedented level of protection is only available with Furmanís SMP technology.

LiFT (Linear Filtering Technology)
Unfortunately, traditional AC filter/conditioners have been designed for unrealistic laboratory conditions. Prior technologies could actually harm audio and video performance more than they help, due to the resonant peaking of their antiquated, non-linear designs. Under certain conditions, these designs can actually add more than 10 dB of noise to the incoming AC line! Worse still, lost digital data, the need to reboot digital presets, or destroyed digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furmanís SMP with LiFT takes another approach, ensuring optimal performance through linear filtering and no leakage to ground.

E.V.S. (Extreme Voltage Shutdown)
Furmanís trusted overvoltage circuitry protects against all too frequent accidental connections to 208 or 240VAC by shutting off the incoming power until the overvoltage condition is corrected.

Rear Panel BNC Connector
For rear panel illumination, a BNC connector is provided for connection of any standard gooseneck lamp, such as the Furman GN-LED or GN-I (sold seperately).

Sequencing
The PS-PRO II Power Conditioner/Sequencers is capable of powering up a rack full of equipment in a 3- step delayed sequence. The sequence is reversed for power-down. The sequence can be initiated with either momentary or maintained switches, locally or remotely. A duplex outlet is provided for each delay step. A front panel screwdriver adjustment sets the delay time for the PS-PRO II. The PS-PRO II also features a locking switch with a removable key for maximum security. One or more Furman PS-PRO II's may be installed in remote locations and operated via low-voltage wiring. The PS-PRO II includes a rear mounted BNC jack which accepts any standard (12VAC, 0.5A) gooseneck lamp for rear rack illumination, as well as a front panel switch which controls the gooseneckís operation.

Optional Accessories
Our PS-REL relay accessory allows a PS-PRO II to be turned on by sensing AC at a pre-amp's switched outlet; also allows daisy-chaining for 6 or more delayed outlet groups.

    What our customers are saying:
    • "Thank you so much. Your customer service department did an outstanding job with our phone order. I will mail the check this week. We appreciate it."
      Catherine E. - Trinity Baptist Church
    • "I cannot thank you enough for helping us in our decision on the Presonus mixer. As I stated on the phone, your patience with me as I asked all kinds of questions is much appreciated. You were not only knowledgeable and professional but your overall sincerity to help was evident, even over the phone."
      Blessings, Pastor Glenn E.
    • "I want to thank Caylen Staub and All Pro Sound for helping me make the right decision on my new Allen & Heath QU-16 console purchase. I didn't know anything about the board and was very apprehensive about buying it. Caylen patiently explained the features and how the board would fulfill my sound needs. I even had second thoughts after receiving it and he talked me through my concerns. He guaranteed I would enjoy the board and he was absolutely right."
      Phillip S. - Richmond, VA
    • "Thank you for putting together the portable projection system for our church. It is exactly what we needed. We received the screen today and I set it up this afternoon. Even in our brightly lit sanctuary on a sunny day with lots of large windows the projector shown brightly with vivid color. I will be sure to call All Pro Sound with any of our future Audio Visual needs. It has been a pleasure working with you."
      Russell A. Jr
    • "I have ordered several things through All Pro Sound, and have always found you guys to have the best products at the best prices. But more than your products, your customer service is second to none. I always deal with Mike Tipton, who is SUPER knowledgeable about all of your products, and SUPER helpful. In short: Mike is awesome! It is always great working with him!"
      Matthew T. - Mercede, CA
    • "Great response time, great prices, and tremendous customer service are just a few of the accolades that describe All Pro Sound. For the past year we have been assisting a fellow church within our denomination with their audio / media design for their new sanctuary. A very special thank you to John Teelin and Steve Maples from All Pro Sound. From the pre wiring stage to the rush deliveries at the finish line, these guys have been there the whole way. Thank you All Pro Sound! We could not have done it without you!!!"
