CONGRA TULA TIONS! Thank you for purchasing the Niles SI-245, one of the most flexible and conve- nient amplifiers ever offered. Like all Niles products, the SI-245 is built to the highest standards of quality control and reliability. With proper installation and operation, you'll enjoy years of trouble-free use.
17 TROUBLESHOO TING GUIDE (continued) SYMPTOM Hum from the speak ers Amp will not tur n on Bass sound is weak and the ster eo image is "phasey" or "blur ry" sounding in one room POSSIBLE CA USES AND TEST PROCEDURE Check for faulty cables, faulty source material, an ungrounded phono system or a defective component.
FEA TURES AND BENEFITS Real W orld Power The SI-245 delivers 45 watts per channel at 8 Ohms and 70 watts per channel at 4 Ohms. You’ll get tremendous bass and dynamics from every pair of speakers powered by an SI-245.
OPERA TION Power Switch The front panel switch is a master or "vacation" power switch. No matter which turn-on mode you have selected, the master power switch will turn off all cir- cuitry —including the sensing circuitry.
INST ALLA TION CONSIDERA TIONS Placement Place the SI-245 on a flat level surface like a table or shelf. It should be placed upright so that its weight rests on the four attached feet. Placing the weight of the amplifier on the rear or front panel for even an instant may result in damage to the amplifier's connectors and controls.
Line Level Audio Input CA UTION! THE AMPLIFIER MUST BE OFF WHENEVER Y OU MAKE CHANGES T O THE INPUT CONNECTIONS. Cascade Audio Outputs The " Cascade Audio Outputs " enable you to connect another amplifier to your preamplifier output. The connectors are gold-plated RCA phono jacks.
Multiple Speaker Loads The SI-245 is stable into very low impedance loads. This means you can safely operate three pairs of 8 ohm speakers (a 2.67 ohm load) directly connected to the SI-245. Note that the SI-245 does not have on/off speaker switching built in.
INST ALLA TION CONSIDERA TIONS 8 Cable and Wir e It will be easier to reconfigure or troubleshoot your system in the future if you label the cables and wires for their destination or source, rather than which ter- minal of the SI-245 they are connected to.
Binding posts for speaker connections. IEC receptacle for AC power cord. FRONT AND REAR P ANEL DET AILS 10 Red “Power” LED confirms the amplifier is connected to a live AC power outlet. (and that the master power switch is on). Green “Active” LED lights when the amplifier circuitry has been turned on by the Turn-On circuits.
