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 covers. Refer servicing to qualified personnel only. The lightning flash with an arrowhead symbol is intended to alert the user to the presence of un-insulated dangerous voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock. WA R N I N G I M P O R TA N T S A F E T Y INSTRUCTIONS (Please read prior to installation) 1. Please read and observe all safety and operating instructions before installing your Merit Series unit. Retain these instructions for future reference. 2. Your Merit Series unit should not be used near water ­ for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool, etc. 3. Do not place your Merit Series unit near heat sources such as radiators, heat registers, stoves, or other appliances that produce heat. THE FURMAN MERIT SERIES F EAT U R E S The M-10 power distributor is a convenient way to power your rack. It provides 10 outlets on its rear panel and carries a 15 amp rating with a circuit breaker. The M-8 power conditioner provides 9 switched outlets for powering equipment. It not only protects anything plugged into it from spikes and surges, but also has a built in AC noise filter to rid the system of RFI / EMI interference. This allows equipment to function better and last longer. In addition to features of the M-8, the M-8L features incandescent rack lights. A dimmer control for the rack lights allows the user to adjust the level of illumination or simply switch the lights off. The M-8L has a master switch for all outlets that glows red when the power is on. The front-panel circuit breaker can be quickly and easily reset should the unit be overloaded. The M-8L also features 5.5 feet of 14 gauge heavy-duty power cable. The M-8L and M-8D utilize a dimmer control for the two retractable front panel light tubes. The dimmer knob controls the brightness of both light fixtures. Turn it clockwise to increase brightness; turn it counterclockwise to decrease brightness. When the lights are not in use, we recommend turning the racklight's switch to off to better maximize the life of the bulbs. Digital Voltmeter: (M-8D) Furman's digital voltmeter continually measures incoming voltages within a typical tolerance of +/-2VAC. It should be noted that the voltage reading is incoming. No adjustment should be necessary on these units. NOTE: The Merit Series units do not compensate for high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally, or are in an area prone to brownouts, you may benefit from the use of one of Furman's AC Line Voltage Regulators. THE FURMAN MERIT SERIES 2.) Symptom: No power to the AC outlets, Possible Cause: Either the AC outlet to which your Merit Series device is connected has no AC voltage present, or the unit has been subjected to a sustained voltage in excess of 400 Volts. Action Needed: Plug the Merit Series unit into an AC receptacle where AC voltage is present. If the problem persists, the protection circuit may be damaged, and require factory service. frequencies than the 50 or 60 Hz AC line, it can be effectively reduced through use of low-pass filtering. M-10 ONE YEAR LIMITED WARRANTY Furman Sound, Inc., having its principal place of business at 1997 South McDowell Blvd., Petaluma, CA 94954 ("Manufacturer") warrants its Merit Series (the "Product") as follows: Manufacturer warrants to the original Purchaser of the Product that the Product sold hereunder will be free from defects in material and workmanship for a period of one year from the date of purchase.

THE FOREGOING IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR 4 M-8 DEFINITIONS SPIKE: This is a pulse of energy on the power line. Spikes can have voltages as high as 6000 volts. Though they are usually of very short duration, the energy they contain can be considerable, enough to damage sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts and degrade wiring insulation. They are an unavoidable component of electric power. They are caused unpredictably by electric motors switching on or off (on the premises or outside), utility company maintenance operations, lightning strikes and other factors. Spikes (also called surges or transients) are absorbed by special components in the Merit Series to provide safe voltage levels to protect your equipment. RFI/EMI INTERFERENCE: Noise from RFI (Radio Frequency Interference) or EMI (Electro Magnetic Interference) involves lower voltages and less energy than is found in spikes, but it is continuous rather than transient in nature. It is not likely to cause damage, but it can certainly be annoying, producing static in audio circuits, "snow" on video screens, or garbled data in computers. Noise can be introduced into AC lines by nearby radio transmitters, certain kinds of lighting, electric motors, and other sources. Because noise occurs at higher M-8L On/Off Rocker Switch: This 15 amp capacity power switch is specifically designed to stand up to the M-8D enormous high inrush current demands of In addition to all the features of the M-8 and many Power Amplifiers. Additionally, the semiM-8L, the M-8D offers a laboratory precision transparent rocker lights when switched to the digital meter that displays incoming voltage in 1"ON" position. volt steps. The voltmeter's accuracy is ±2 volts. The M-8D has a master switch for all outlets that glows red when the power is on. The frontpanel circuit breaker can be quickly and easily reset should the unit be overloaded. The M-8D also features 5.5 feet of 14 gauge heavy-duty power cable.
