Safety Information - Warnings
Please read and observe all of the safety and operating instructions before the SPR-20i is operated. Retain these instructions for future reference.
•Do not disassemble or modify in any way. No user-serviceable parts inside.
•Keep away from moisture and avoid excessive humidity.
•Do not allow liquids or foreign objects to enter the unit.
The SPR-20i should be serviced by qualified service personnel when:
•The power supply cord or plug has been frayed or cut.
•Objects have fallen or liquid has spilled into the unit.
•The SPR-20i has been exposed to rain or other moisture.
•The SPR-20i does not appear to operate normally, or exhibits a marked change in performance.
•The SPR-20i has been dropped, or the enclosure damaged.
The SPR-20i requires that a safety ground be present for proper operation. Any attempt to operate the SPR-20i without a safety ground is considered improper operation and will invalidate the warranty.
Power Source
The power source to which the SPR-20i is connected should be adequate for use at 20 Amps. Though the system may function with a 15 Amp panel circuit breaker, nuisance circuit breaker tripping could result at your service panel. If your system includes multi-channel audio power amplifiers that require more than modest power demands, a circuit breaker with a rating of at least 20 Amps is essential for optimum performance. If other electrical loads are used on this same AC line, and the continuous load from your equipment is in excess of 10 Amps, we recommend a 30 Amp circuit breaker wired with #10 gauge wire. For installations which must comply with NEC codes, a dedicated 20 Amp circuit is the minimum requirement. If in doubt, consult your local electrician. In rare instances, two SPR-20i may be required for the most ambitious 5.1 and 7.1 home theater systems with continuous current draw in excess of 20 Amps (consult your sales professional, or Furman Sound technical assistance).
Placement
The SPR-20i is manufactured with four rubber feet for placement on any table, cabinet, shelf, or floor. These rubber feet may be easily removed with a standard Philips screw driver when rack mounting adjacent to other components. Because of the SPR-20i’s internal shielding, placement or proximity to other components is not critical, and the SPR-20i does not produce any appreciable heat under standard use. The SPR-20i may also be rack mounted in a standard 19” rack by attaching the SPR-20i rack ears. These rack ears (contained within the plastic rack kit package) mount flush with the back portion of the SPR-20i’s front panel. They are attached to the chassis by removing the (2) countersunk screws on each forward-side of the chassis top cover. Each rack ear is installed with (3) pan-head Philips screws contained within the SPR-20i rack mounting kit. The third screw used for each rack ear is for the center hole, located towards the rear and aids in stabilizing the unit when rack mounted.
