9EnglishTroubleshootingMost dificulties in audio systems are the result of poor or wrong connections, or improper control settings. If you encounter problems, isolate the area of the dificulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the ampliier, refer to the suggestions for the following conditions:Front Panel Power Indicator Is Not LitNo main power to the ampliier. Check the front panel power switch. Make sure that it is set to the on position. Check AC power connections at the ampliier and the AC outlet. Fuse Replacement 8 RB-1582 OnlyIf everything checks out correctly and you still cannot get the ampliier to turn on, check for a blown fuse. Disconnect the AC from the wall and remove the fuse holder 8 on the back panel. If the fuse is blown, replace with a new fuse and try again.Note: Make sure that the power cord is disconnected from the wall before checking or replacing the fuse. Replace only with the identical size and type fuse (3AG125V12A for U.S. version or 5ST6.3 for European version).The RB-1552 has an internal fuse. If you suspect the fuse is blown take the ampliier to an authorized Rotel service agency to have it checked. Do not attempt to do this yourself. Opening the enclosure of the ampliier exposes you to dangerous voltages. No SoundIf the amp is getting AC power, but is producing no sound, check the Protection indicator on the front panel. If it is lit, see below. If not, check all of your connections and control settings on associated components. Protection Indicator Is LitThe front panel indicator lights when the ampliier protection circuits have shut off the ampliier. Typically, this occurs only when the ventilation openings are blocked, when there is faulty speaker wiring, or after a period of extreme use. Turn off the system and wait for the amp to cool. Then push the front panel power switch in and out to reset the protection devices. If the problem is not corrected or reoccurs, there is a problem with the system or the ampliier itself.SpeciicationsRB-1552Continuous Power Output 130 watts/channel(20-20 kHz, < 0.03%, 8 ohms)Total Harmonic Distortion (20Hz-20kHz, 8 ohms) < 0.03%Intermodulation Distortion (60 Hz : 7 kHz, 4:1) < 0.03%Frequency Response ( +0.5, –3dB) 4Hz - 100kHzDamping Factor (20-20,000 Hz, 8 ohms) 450Speaker Impedance 4 ohms minimumSignal to Noise Ratio (IHF A network) 120 dBInput Impedance/Sensitivity 12 k Ohms/1.5 voltGain 26.6 dBPower Requirements U.S. version 120 Volts, 60 Hz European version 230 Volts, 50 HzPower Consumption 400 WattsDimensions Width x Height x Depth 431 x 144 x 339 mm 17 x 57/8 x 133/8 ins.
