The P-2400 IT features a specially wound and shielded toroidal balanced isolaon transformer specically designed to reduce hum pickup by sensive equipment when ultra-low-noise is a must. Addionally, Furman’s revoluonary Series Mul-stage Protecon (SMP) cir- cuit, as well as our exclusive Linear Filtering Technology (LiFT) are combined to ensure what our customers have grown to expect from Furman - uncompromised surge protecon and power puricaon. The Furman P-2400 IT has been precisely engineered to more than meet the crical demands of audio/video professionals, contractors, broadcasters, and musicians alike. DESCRIPTION Designed for the most crical, ultra-low noise installaons, the P-2400 IT can supply 20 amps of balanced AC power for recording stu- dios, broadcast staons, video producon facilies, or any environment requiring a studio quality signal to noise rao. To understand the incredible need for clean noise-free AC power, it’s important to note that today’s sophiscated studio equipment features tremendous dynamic range. Most of the signal content that denes high resoluon audio (such as harmonics, instrument mbre, high frequency extension, spaal cues, and fast transient aacks), are inherently low in signal level. Further, when AC noise is induced into audio processors, pre-ampliers, microphones, powered monitors, computers, and mixing consoles, the all important low level signals are distorted or masked! Once signals are masked there is no way to retrieve the lost content. Advanced AC ltering is crical when audio or video resoluon is at stake. With Furman’s P-2400 IT, you will hear audio content and see video images as they were meant to be - prisne. SMP (Series Mul-Stage Protecon) with EVS (Extreme Voltage Shutdown) Furman’s SMP surge suppression virtually eliminates service calls and costly “down me”. Tradional surge suppression circuits sacri- ce themselves when exposed to mulple transient voltage spikes, requiring the dismantling of your system and repair of your surge suppressor. Not so with Furman’s SMP. With SMP, damaging transient voltages are safely absorbed, clamped and dissipated. Your connected equipment is protected, while your Furman protects itself! Unique to Furman’s SMP is its unparalleled clamping voltage. While other designs oer clamping voltages that are well above 330 Vpk, Furman’s SMP clamps at 188 Vpk, (133 VAC RMS) even when tested with mulple 6000 Vpk - 3000 amp surges! This unprec- edented level of protecon is only available with Furman’s SMP technology. Addionally, Furman’s trusted over-voltage (EVS) circuitry protects against all too frequent accidental connecons to 208 or 240 VAC, or intermient neutral. It does so by shung o the incoming power unl the over voltage condion is corrected and the power switch is reset. LiFT (Linear Filtering Technology) Unfortunately, tradional AC lter - condioners have been designed for unrealisc laboratory condions. Prior technologies, whether mulple pole lters or convenonal series mode, could actually harm audio and video performance more than they help, due to the resonant peaking of their anquated, non-linear designs. Under certain condions, these designs can actually add more than 10 dB of noise to the incoming AC line! Worse sll, lost digital data, the need to re-boot digital pre-sets or destroyed digital converters, are frequently caused by excessive voltage spikes and AC noise contaminang the equipment ground. Furman’s SMP with LiFT takes a dif- ferent approach, ensuring opmal performance through linear ltering and no contaminaon or leakage to ground.5 FRANÇAIS ENGLISH ESPAÑOL Addional Features The P-2400 IT oers a switchable laboratory precision digital meter that displays incoming voltage in 1-volt steps or true RMS cur- rent in 0.1 amp steps. The voltmeter’s accuracy is ±1.5 volts and features a tri-color voltage range indicator. This informs the user whether voltage is in or out of a safe range, even from a distance too great to accurately read the displayed voltage. SAFETY INFORMATION To obtain best results from your Furman Presge Series Power Condioner, please read this manual carefully before using. WARNING To reduce the risk of electrical shock, do not expose this equipment to rain or moisture. Dangerous high voltages are present inside the enclosure. Do not remove the cover. Refer servicing to qualied personnel only.

IMPORTANT SAFETY INSTRUCTIONS

(Please read prior to installaon) 1. Please read and observe all safety and operang instrucons before installing your Furman Presge Series power condioner. Retain these instrucons for future reference. 2. Your Presge Series condioner should not be used near water – for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. 3. Do not place your Presge Series condioner near high heat sources such as radiators, heat registers, stoves, or other appliances that produce extreme heat. 4. The Furman P-2400 IT should only be connected to a 120 VAC, 60Hz, 20 amp grounded electrical outlet. Do not defeat the ground or change polarizaon of the power plug. 5. Route the AC power cord and other cables so that they are not likely to be walked on, tripped over, or stressed. Pay parcular at- tenon to the condion of the cords and cables at the plugs, and the point where they exit your Furman condioner. To prevent risk of re or injury, damaged cords and cables should be replaced immediately.

Clean your Furman condioner with a damp cloth only. Do not use solvents or abrasive cleaners. Never pour liquid on or into the unit.

7. Your Furman condioner should be serviced by qualied service personnel when:

• The power supply cord or the plug has been frayed, kinked, or cut.

• Objects have fallen or liquid has spilled into the unit.

• The unit has been exposed to rain or extreme moisture.

• The unit does not appear to operate normally.

• The “Protecon OK” indicator is not lit.

• The unit has been dropped, or the enclosure has been damaged.

8. Your Furman condioner requires that a safety ground be present for proper operaon.

9. Do not aempt to service your Furman condioner beyond what is described in this manual. All other servicing should be re- ferred to qualied service personnel. NOTE: Furman’s P-2400 IT does not compensate for high or low AC line voltage. If you frequently move your rack to dierent loca- ons, derive power from generators, use excessively long extension cords, travel internaonally, or are in an area prone to brown- outs, you may benet from the use of one of Furman’s AC Line Voltage Regulators. INSTALLATION The power source into which the P-2400 IT is connected must be adequate for use at 20 amps. We recommend either a 30 amp circuit, wired with 10 gauge wiring, when connuous operaon near 20 amps is ancipated, or a dedicated 20 amp circuit. Consult a qualied electrician when in doubt. The P-2400 IT is designed for mounng in a standard 19 inch equipment rack. Because of its weight, the best posion is the boom slot of the rack. Its toroidal transformer minimizes magnec leakage, but nevertheless, due to its high capacity, it may radiate a6

small magnec eld. Therefore, we recommend that it not be posioned adjacent to sensive, low level signal processors, especially mic preamps, mixers, tape recorders, etc. Power amps may be more suitable “rack neighbors.” The maximum benet derived from balanced power is when it powers ALL equipment in an installaon. Therefore, try to posion the P-2400 IT in a central locaon so its power can be easily distributed everywhere it’s needed. If the total power consumpon of all equipment exceeds 20 amps at 120 volts, delete high level or mechanical devices rst (such as power amps, motors). If possible, physically isolate any equipment that has to be powered with convenonal power through a dierent circuit, and route AC cords away from all other cabling. The balanced power produced by the P-2400 IT is restricted to use with electronic equipment only. Balanced power may not be used for lighng equipment, and access must be limited to use by qualied personnel only. Rear Rack Mounng: If you are installing the P-2400 IT in a rack that has rear as well as front mounng rails, you may easily secure it to the rear of your rack. Simply remove the securing screws from the side and front porons of the P-2400 IT’s adjustable rear rack ear and reinforcement side plate (located on either chassis side), reverse it and re-aach to the P-2400 IT chassis. (See Figure 1.a, page 12) OPERATION Switchable Voltage and True RMS Current Meter: Furman’s laboratory precision AC digital voltmeter connually measures incoming voltages within a typical tolerance of +/-1.5VAC. It should be noted that the voltage reading is incoming. Furman’s laboratory precision True RMS digital current meter connually measures the total circuit AC load within a typical tolerance of +/- 0.5 amp. Because these meters feature true RMS technology, the current readings are accurate regardless of load condions (capacive, inducve, or resisve). To switch between voltage and current, press the buon labeled “Line Voltage/Current”. Hold this buon down for two seconds to dim the brightness of the display. Voltage Range Indicator: This indicator is located in the lower le corner of the digital volt / amp meter lens assembly. When AC voltage is within 5 volts (+/-) of a nominal 120VAC source, this tri-color indicator will be green (opmal). However, if the voltage is between 110 to 114VAC, or be- tween 126 to 130VAC, the indicator will turn amber (cauon - not opmal). If the incoming voltage is in an extreme range (below 110 or above 130), the indicator will turn red. This range is far from opmal, and may be potenally damaging to some equipment. Ground Fault Interrupter (GFCI): The Ground Fault Circuit Interrupter (GFCI) on the P-2400 IT’s rear panel is a special kind of circuit breaker that detects an imbalance in the current owing into the two hot legs. The “missing” current is presumed to be owing through the ground conductor (the round pin on an AC outlet). Ground current oen indicates a dangerous paral or full short circuit. If an imbalance is detected, the GFCI trips and cuts o power not only to itself, but to all the P-2400 IT outlets. If this occurs, the buon on the GFCI marked “R” (Reset) will pop out. To restore operaon, correct the fault and push the buon in. You may test the proper operaon of the GFCI at any me by simulang a ground fault by pushing the buon marked “T” (Test). If the GFCI is working properly, this will cause the “R” buon to pop out and cut o power. You can restore operaon aer a test by pushing in the “R” buon. Ground Li Switch: Ground loops are fairly common in many installaons because AC cords with safety grounds are rarely connected to a single low-resis- tance bus bar. When there is a signicant dierence in voltage between a source component’s neutral and ground and a load compo- nent’s neutral and ground, the buzz and hum associated with this type of ground current noise (or loop) may occur. Addionally, many AC noise contaminants may be present on the AC ground wire. For these reasons, Furman’s P-2400 IT contains a Ground Li Switch. This switch oats the output ground, eliminang ground noise and also, in many instances, the hum and buzz associated with ground loops. The P-2400 IT’s GFCI protecon circuit assures that even when ulizing the power condioner in this mode, operaon is safe and secure. In fact, even if a connected component has a catastrophic failure, less than 5 milliamps current imbalance from line to ground or neutral to ground will instantly disconnect the voltage output from the P-2400 IT. This is far safer than any convenonal 120 VAC outlet and it has numerous noise reducing advantages. However, ground wiring in any studio, broadcast or club environment can be complex. Because all 14 outlets of the P-2400 IT are in parallel, it is sll possible to have a ground loop if the two oending products are simultaneously connected to a single P-2400 IT. Use of mulple P-2400 IT’s may be necessary in extreme cases. Also, for studio and broadcast use, separang all digital processing products from all analog devices is highly recommended and can be accomplished by separang these components into the two isolated banks, or for the very best performance, using two P-2400 IT’s.7 FRANÇAIS ENGLISH ESPAÑOL In the end, it is best to experiment with the Ground Li Switch. Whichever posion yields the least noise or clearest audio / video recording or reproducon, is the posion that should be ulized. Ultra-Low Resistance Magnec Power Switch / Circuit Breaker: Furman’s Presge Series 20 amp capacity power switch is specically designed to stand up to the enormous high in-rush current de- mands of many power ampliers. Addionally, Furman magnec circuit breakers are not sensive to temperature, nor do they raise the AC impedance as many less costly thermal breakers will do. If the 20 amp RMS current capacity of the P-2400 IT is exceeded, the spring tensioned switch will immediately switch to the o posion. You will need to switch the toggle back to the on posion once the problem is corrected (typically by eliminang one component, or unl the RMS current does not exceed 20 amps or 2400 was). Extreme Voltage Shutdown Indicator: The Extreme Voltage LED indicator is normally o. It is located within the meter lens assembly directly above the blue voltage / cur- rent LED’s, though during normal use it will NOT be visible. The Extreme Voltage Shutdown (EVS) indicator monitors a hazard common in the entertainment, remote broadcast, and AV contrac- tor industries:wiring faults. For example, accidental connecon to 208VAC where 120VAC is expected, or an open series neutral from a 208 to 240VAC electrical service. The Furman EVS circuit senses voltages that are so high that operaon would be impossible and shuts the power down before damage can occur. Upon inially applying power to the P-2400 IT, the Extreme Voltage indicator will illuminate to a bright red if the input voltage is above the extreme voltage cuto. When this occurs, power will not be applied to the outlets. If the unit has been operang with an acceptable input voltage and subsequently that voltage exceeds 140V, it will shut o power to the outlets and the Extreme Volt- age LED will light. NOTE: If the mains power is above the high cuto voltage and has caused the EVS circuit to remove power from the outlets, it can- not restore power without the operator manually turning the unit o, then on again. Avoid turning the unit back on without rst checking the source of the problem and perhaps changing the AC source. Protecon OK Indicator: Although the Furman SMP circuit assures virtually maintenance free protecon from transient voltage spikes and surges, nature has a way of occasionally creang electrical forces that are beyond the capabilies of ANY TVSS device to absorb without some degree of damage (such as a direct lightning hit in an outdoor applicaon). In the rare instance that this occurs, the green “Protecon OK” LED indicator (located at the boom right of the meter display), will no longer illuminate. If this happens, some level of protecon from voltage surges will remain, but the Furman’s clamping voltage rang will be compromised. The unit must be returned to Fur- man. USB Charger: The Furman P-2400 IT’s USB charger provides an easy way to recharge many popular electronic accessories as well as cellular com- municaon devices by simply plugging the re-charge cord into the front panel socket. Please note: because there are currently many standards for USB, some devices may not be compable with our charger. How Balanced AC Power Works: In much the same way that balanced audio lines can reduce the pickup of hum and other types of electromagnec interference (EMI), the use of balanced AC power lines in sensive audio, video, or computer installaons can make an enormous dierence in system noise and signal integrity. But power distribuon in North America, unfortunately, is not balanced. The distribuon standards currently in use were derived from pracces established over a century ago, when electric power use was limited to lighng and motors, long before any AC noise sensive applicaons existed. The em- phasis then was on convenience and safety, but not noise cancellaon. The result was a three-wire distribuon scheme in which 120V branch circuits have a hot wire and a neutral wire, with the neutral ed to a third wire connected for safety to an earth ground. The third wire does not carry any current unless there is a fault. This unbalanced scheme can create hum in audio circuits for two main reasons. First, the current owing in the hot wire induces hum in any other nearby wires, which may carry vulnerable low-level audio or video signals. Second, because the impedance of chassis and cable shielding to ground is always greater than zero ohms, ground current owing from power supply capacitors and from EMI pickup causes a voltage drop at 60 Hz and its harmonics. This low level noise becomes part of the audio signals.8

P-2400 IT OWNER’S MANUAL

With a center-tapped isolaon transformer, the AC power feeding a studio can be balanced at its source. The current-carrying wires then are no longer “hot” (120V) and “neutral” (0V), but two 60V lines of opposite polarity (referenced to ground connected to the center tap), whose dierence is 120V. This type of power, when run around a room, does not induce hum into nearby audio wiring because the two conductors induce equal and opposite voltages that cancel each other. Similarly, ground currents are all but eliminated by the same common-mode cancellaon eect. No longer is it necessary to adopt cumbersome and expensive star-ground systems or use massive bus bars or heavy ground rods. Further, with features such as our center tap ground li, ground induced noise may be reduced even further. Of course Balanced AC Power is only the beginning of a system free of AC noise. Asymmetrical noise, or what is called “dierenal mode,” is responsible for well over half the noise present in today’s AC lines. For this reason we employ our exclusive Linear Filtering Technology (LiFT). This assures that your audio, video, or computer signals are as pure and uncorrupted as possible. TROUBLESHOOTING 1.) Symptom: No power to the AC outlets; “Protecon OK” indicator is not lit. Possible Cause: Either the AC outlet to which your Furman condioner is connected has no AC voltage present, or the unit has been subjected to a sustained voltage in excess of 400 Volts. Acon Needed: Plug the Furman condioner into an AC receptacle where a nominal 120 VAC is present. If the problem persists, the protecon circuit may be damaged, and require factory service. 2.) Symptom: No power to the AC outlets, “Protecon OK” indicator is lit. Possible Cause: Either the GFCI test buon has been tripped (such as in transport or aer shipping), or; there’s an excess of 5mA of ground leakage to one of the connected components. Acon Needed: Depress the “reset” buon on the rear panel’s GFCI outlet. If the buon pops out immediately when the unit is ener- gized, there may be an oending product that needs to be removed or possibly repaired. 3.) Symptom: Extreme Voltage (EVS) indicator lit. Possible Cause: Input voltage is above 140 volts causing power to the unit’s outlets to be shut down. Addionally, if the voltage is below 85 - 90 volts at turn on, the unit will not allow AC voltage to reach the outlets. Acon Needed: Correct the line voltage, and then turn the Furman condioner on. If the voltage present is well below 114 VAC, or above 126 VAC, consider installing a Furman voltage regulator.
