PROTECTION OK:This LED is normally on when the power to the PM-PRO's outlets is switched on. It monitors the integrity of the protection devices and reports if the protection is compromised. If an extremely large spike is encoun- tered that exceeds the PM-PRO's capacity, the main group of input protectors will blow an internal fuse, causing the indicator to go out. If this LED is not lit when the power switch is on, full protection is not functioning. Spike protection may still exist, but will have a reduced capacity to absorb current. If this LED is not lit, please contact the Furman Service Department.

GROUND OK: This LED is normally on when the power to the PM-PRO's outlets is switched on. It monitors the integrity of the grounding, and reports if the ground- ing is compromised. It lights if a reasonably good safety ground exists. If this LED is not lit when the power is on, the PM-PRO is not properly grounded. Unplug the PM-PRO and correct the ground. (Not available on PM-PRO-E.)

EXTREME VOLTAGE SHUTDOWN:This LED status indicator is normally off. It monitors a hazard unfortunately common in the entertainment industry: wiring faults -- for example, accidental connection to 220V where 120V is expected. The PM-PRO senses voltages that are so high or low that operation would be impossible and shuts the power down before damage can occur. For the PM- PRO, the cutoff voltages are under 80V or over 140V; for the PM-PRO-E, under 160V or over 280V. Upon initially applying power to the PM-PRO, this indicator will be lit if the input voltage is below the low cutoff or above the high cutoff, and power will not be applied to the PM-PRO's outlets. If the unit has been operat- ing within an acceptable input voltage and then that voltage goes out of the ac- ceptable range, the PM-PRO will shut power to the outlet and this LED will begin flashing.

NOTE: If the mains power is below the low cutoff voltage and has caused the PM-PRO to remove power from its outlets, the PM-PRO will not restore power to the outlets until the mains voltage rises to more than 10V above the cutoff. Similarly, if the mains power is above the high cutoff and has caused a shut- down, the PM-PRO will not restore power to the outlets until the mains voltage falls more than 10V below the cutoff. The reason for this is to prevent the power oscillating on and off in marginal conditions.

LED VOLTMETER: This three-color, 20 LED bargraph is an accurate, self-check- ing AC voltmeter that continually measures normal voltages. The meter reads from 90 to 128 volts in 2 volt steps (PM-Pro-E: 180 to 256 volts, in 4 volt steps). The normal range voltages are indicated in green, with moderate and extremely high or low voltages in yellow and red respectively (see chart on

PM-PRO, PM-PRO-E specifications

Furman Sound is a renowned brand in the audio industry, known for its innovative power management and audio solutions. Among their impressive lineup, the Furman PM-PRO and PM-PRO-E power sequencers stand out for their exceptional features and technologies that cater to the needs of professionals in audio production and live sound environments.

The Furman PM-PRO is designed to ensure that audio equipment receives clean and reliable power, reducing the risks of audio distortion and equipment damage. One of its key features is the "Linear Filtering Technology," which effectively eliminates RF interference and provides a noise-free audio experience. This is crucial for musicians, engineers, and venues seeking pristine sound quality.

Additionally, the PM-PRO incorporates a built-in “voltage regulator,” which safeguards connected gear against voltage spikes and drops. This protection is vital, particularly in environments where power supply can be inconsistent. With a maximum load of 15 amps, the PM-PRO can accommodate a variety of audio gear, making it suitable for both studio and live performances.

Another standout feature of the PM-PRO is its "soft start" technology, which allows equipment to power on smoothly, reducing the risk of pops and potential damage that can occur with abrupt power surges. The device also includes a computer interface, allowing users to monitor voltage levels and power conditions in real-time through compatible software.

The PM-PRO-E variant introduces additional enhancements for even greater control and protection. It features advanced network capabilities, enabling remote monitoring and management of power distribution through an Ethernet connection. This is particularly beneficial for large installations, providing integrators with the tools to troubleshoot and manage power usage efficiently.

Both the PM-PRO and PM-PRO-E come equipped with multiple outlets to accommodate an array of audio equipment, and their rack-mountable design ensures they integrate seamlessly into any professional setup. Furman’s commitment to quality is evident in the robust construction of these devices, designed to withstand the rigors of live performance and studio use.

In conclusion, the Furman Sound PM-PRO and PM-PRO-E serve as essential power management solutions that prioritize performance, reliability, and user control. Their advanced technologies not only enhance sound quality but also protect valuable audio equipment, making them invaluable assets for anyone serious about sound production. Whether in the studio or on stage, these devices are engineered to deliver consistent and interference-free power, meeting the demands of discerning audio professionals.
