[. . . ] AUDIO POWER SPECIFICATIONS POWER OUTPUT AND TOTAL HARMONIC DISTORTION 60 watts per channel minimum continuous average power into 4 ohms, both channels driven from 20 Hz to 20 kHz with no more than 1 % total harmonic distortion per Car Audio Ad Hoc Committee standards. other Specifications OTL (output transformerless) circuit Pulse power supply Inputs RCA pin jacks High level input connector Input level adjustment range 0. 8 ­ 12 V (High level input) Outputs Speaker terminals Speaker impedance 2 ­ 8 (stereo) 4 ­ 8 (when used as a bridging amplifier) Maximum output 4 Speakers: 110 W × 4 (at 4 ) 3 Speakers: 150 W × 2 (at 2 ) + 300 W × 1 (BTL, at 4 ) Rated output (supply voltage at 14. Halogenated flame retardants are not used in cabinets. [. . . ] Hi-level Sensing Power On feature allows unit to be activated without need for REMOTE connection. Direct connection can be made with the speaker output of your car audio unit if it is not equipped with the line output (High level input connection). * Pulse power supply This unit has a built-in power regulator which converts the power supplied by the 12 V DC car battery into high speed pulses using a semiconductor switch. These pulses are stepped up by the built-in pulse transformer and separated into both positive and negative power supplies before being converted into direct current again. This is to regulate fluctuating voltage from the car battery. This light weight power supply system provides a highly efficient power supply with a low impedance output. * Protection circuit This amplifier is provided with a protection circuit that operates in the following cases: -- when the unit is overheated -- when a DC current is generated -- when the speaker terminals are short-circuited. The color of the POWER/PROTECTOR indicator will change from green to red, and the unit will shut down. If this happens, turn off the connected equipment, take out the cassette tape or disc, and determine the cause of the malfunction. If the amplifier has overheated, wait until the unit cools down before use. If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer. If the fuse blows, check the power connection and replace both the fuses. If the fuse blows again after replacement, there may be an internal malfunction.
