Extreme Voltage Shutdown Indicator

The AC Series SMP+ circuit senses voltages

that are high enough to cause damage to your

components, and shuts the power down before

damage can occur.

The Extreme Voltage Shutdown LED is normally off. If an input voltage in excess of 137VAC [or 270 VAC for the AC-210 E] is

sensed, either on initial power-up or during

normal operation, the AC-215 / AC-210 E will shut off power and this indicator will light.

NOTE: If the mains power is above the high cutoff voltage and has caused the unit to remove power from its outlets, it cannot restore power without the operator manually turning the unit off, then on again. Avoid turning the unit back on, without ﬁ rst checking the source of the problem, and perhaps changing the AC source.

Protection OK Indicator

Although the Furman SMP+ circuit assures protection from transient voltage spikes and surges, nature has a way of occasionally creating electrical forces that are beyond the capabilities of any TVSS device to absorb without some degree of damage. In the rare instance that this occurs, the green “Protection OK” LED indicator located on your front panel will turn off. If this happens, some level of protection from voltage surges will remain,

but the Furman’s clamping voltage rating will be compromised. The unit must be returned

to Furman Sound, or an authorized Furman Service center for repair.

Symptom : No power to the AC outlets.

Possible Cause : Circuit breaker has tripped due to excessive load.

Action Needed : Unplug one piece of equipment from the AC-215 / AC-210 E, and push the re-set tab into the Circuit breaker bezel.

Symptom : No power to the AC outlets, even after the Circuit breaker has been re-set.

Possible Cause : Protection devices are damaged.

pmn specifications

Furman Sound PMN series products represent a notable advancement in power management technology for professional audio applications. These devices are designed with a focus on delivering clean, reliable power to audio and lighting equipment, ensuring optimal performance in varied environments such as live events, studios, and installations.

One of the key features of the Furman PMN series is its advanced power conditioning capabilities. The built-in Linear Filtering Technology (LiFT) is engineered to significantly reduce noise across the entire audio spectrum, resulting in clearer sound reproduction. This is particularly beneficial for audio professionals who rely on high fidelity in their work. By effectively filtering out electromagnetic and radio frequency interference, the PMN series ensures that equipment operates at its full potential without the distraction of unwanted noise.

Another standout aspect of the PMN series is its robust surge protection. Utilizing the technology of SmartSequencing, these units protect sensitive equipment from power spikes and surges that can occur during live performances or in uncertain electrical conditions. This feature is essential for maintaining equipment longevity and is a vital consideration for professional users who invest heavily in audio gear that can be easily damaged.

The ergonomic design of the PMN units is also worth noting. These devices are housed in durable, rack-mountable chassis that promotes ease of use and enhances portability. Their intuitive front panel displays vital information, such as voltage status and load indicators, allowing users to monitor their systems at a glance.

Additionally, the PMN series includes multiple outlets, providing ample connectivity for various audio and lighting devices. The outlets are often designed with user-friendly considerations, ensuring that cables can be easily accessed and organized, thus minimizing setup time and clutter.

Thermal management in the PMN units is another critical feature. With integrated fans designed to maintain optimal operating temperatures, the systems can handle high loads without risking overheating, thus enhancing reliability during extended use.

Overall, with its combination of noise reduction, surge protection, convenience, and durability, Furman Sound's PMN series stands out as a vital tool for audio professionals. Whether in a studio, on stage, or in a fixed installation, the PMN provides the reliability and performance needed to ensure the highest quality audio experience.
