User manual RANE FRS 8

[. . . ] OPERATING / SERVICE MANUAL GENERAL INSTRUCTIONS Using the FRS 8 is as easy as it looks, and should not present any problems. Connect the red outputs of the FRS 8 to the red input jacks on the products to be powered using the supplied 6-wire modular connector cables. The power switch controls all units powered from the FRS 8. [. . . ] Additionally, create as much ventilation space around the FRS 8 as possible. This is not critical, it is just good practice. When fully loaded, the FRS 8 requires unrestricted airflow into the bottom and out the top of the unit for proper cooling. TOO MUCH CURRENT Sometimes you may be tempted to try and power two units from one output of the FRS 8. If the total current demand of both units is less than the 650 mA output current, this daisychaining (running power out of one unit into another) temptation becomes unbearable. In general, avoid daisychaining of power supplies. Daisychaining of power only works between units interconnected by fully balanced techniques. There can be no signal ground connecting daisychained units. Failure to follow this rule results in hum due to an unbreakable ground loop caused by the common power supply path. Life is simpler if you just say no. POWER SUPPLY CABLES Each FRS 8 is shipped with (8) 6-wire modular plug power supply cables. Additional power supply cables are available from the factory or your dealer. Two lengths are offered, either 24 inches (package of 4), or 6 feet (package of 3). Please specify length when ordering. RESETTING TIME The FRS 8 is protected by solid-state current and temperature sensing devices that reset automatically. This automatic resetting takes approximately 15 minutes depending upon the nature of the overload. If power is lost on an output, disconnect the power cable and wait at least 15 minutes before reconnecting the cable. [. . . ] COMMON 4-WIRE CABLE AND CONNECTORS WILL NOT WORK. DO NOT SUBSTITUTE 4-WIRE FOR 6-WIRE CABLE AND CONNECTORS. ©Rane Corporation 10802 47th Avenue West, Mukilteo WA 98275-5098 TEL(206) 355-6000 FAX(206) 347-7757 Printed in the U. S.
