Pros & Cons
👍 Pros
- SMP surge protection maintains full clamping effectiveness over time, unlike standard MOV-based protectors that degrade with each surge event.
- Isolated outlet banks prevent inter-component noise contamination between sensitive analog and noisy digital equipment.
- Front-panel voltmeter and ammeter provide real-time monitoring of incoming voltage and total current draw.
- 20-amp rating with high-inrush magnetic circuit breaker supports demanding equipment loads without nuisance tripping.
- Rack-mountable design fits standard 19-inch equipment racks for clean, professional installation.
👎 Cons
- Requires a dedicated 20-amp NEMA outlet, which may not be available in all studios or venues without electrical work.
- Higher price point than basic power strips and standard surge protectors.
- Does not include automatic voltage regulation (AVR) for environments with significant voltage fluctuations.
- The unit adds weight and takes up a full rack space in your equipment rack.
Frequently Asked Questions
What is Furman's SMP technology and how does it protect equipment?
SMP (Series Multi-Stage Protection) is Furman's proprietary surge suppression technology. Unlike standard MOV-based protectors that degrade over time, SMP uses a multi-stage clamping circuit that absorbs and dissipates voltage spikes without sacrificing protection capacity over repeated surge events.
Why does the PL-PRO DMC have isolated outlet banks?
Isolated outlet banks prevent electrical noise generated by one piece of equipment from bleeding into the power supply of another. This is especially important in audio and video rigs where digital devices can introduce interference that degrades the signal quality of sensitive analog gear.
What type of power outlet does the PL-PRO DMC require?
The PL-PRO DMC requires a 20-amp NEMA outlet (NEMA 5-20R), which has a T-shaped neutral slot. Standard 15-amp outlets will not accept the 20-amp plug. Verify that your venue or studio has 20-amp circuits before purchasing.
What do the voltmeter and ammeter displays show?
The front-panel voltmeter shows the incoming AC voltage from the wall, letting you verify you're receiving proper voltage. The ammeter displays the total current draw of all connected equipment, helping you avoid overloading the circuit.
Does the PL-PRO DMC condition power or just protect against surges?
It does both. Beyond surge and spike protection via SMP, the unit conditions incoming power by filtering EMI and RFI noise through its isolated outlet banks, delivering cleaner AC power to connected equipment.
