Installation
Unpacking
Before unpacking your unit, inspect the carton for any obvious severe damage to the box and internal protective materials.
If internal damage is likely, contact the carrier who delivered the unit before proceeding with unpacking. If, after unpacking,
shipping damage is evident, contact the carrier. Save all shipping and packing materials. You may need them if you should
ever have to return the unit to the factory for servicing.
The box should contain the SPR-20i unit, detachable AC cord, rack mount kit, owner’s manual, and warranty registration
card. If anything is missing, please contact Furman Customer Service. Fill out and return your warranty registration card.
Registration is recommended because it can be used to establish whether the unit is within the warranty period should your
original ownership documents be lost, and it assists us in informing you about upgrades or other vital information.
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.
