THE FURMAN MERIT SERIES F EAT U R E S
M-10
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-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 �xtures. 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 bene�t from the use of one of Furman�s AC Line Voltage Regulators.

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 �ltering.

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 Purchaser of the product is allowed �fteen days from the date of purchase to complete warranty registration by mail or on-line at the Furman website. If the Product does not conform to this Limited Warranty during the warranty period (as herein above speci�ed), Purchaser shall notify Manufacturer in writing of the claimed defects. If the defects are of such type and

M-8
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 �lter to rid the system of RFI / EMI interference. This allows equipment to function better and last longer.

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
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.

On/Off Rocker Switch: This 15 amp capacity power switch is speci�cally 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 Ampli�ers. 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.
