Or, if another stereo component has a built- in infrared remote sensor and a Remote Output jack, it may be possible to

9、connect this jack to the REMOTE IN jack of your amplifier. All Harman Kardon products with Remote In and Remote Out jacks are compatible with one another, except for the Citation 22, 24 and 25. Other manufacturers remote sensors and components may not be compatible, but it will not hurt to experimen

10、t. A second wire may be used to connect your amplifiers REMOTE OUT jack to the Remote Input of another stereo component. Continue this process to include additional components (if compatible). Connecting Speakers 1. For best performance, use high quality speaker cables. However, ordinary copper wire

11、 can be used if the gauge meets the following requirements: Wire Min. Length Diameter Up to 2.5 meter 1 mm Up to 4 meter 1.25 mm Up to 6 meter 1.6 mm Above 6 meter 2- 2.5 mm 2. Avoid rolling excess wire with or near signal interconnects. External Power Amplifiers For applications where higher power

12、is desired, connect the Pre- Out Jacks to the Main In Jacks of an external power amplifier. The level of the output can be adjusted between - 3 and +3 dB with an internal button. To adjust the level, gently insert a small screwdriver into the button and turn clockwise to increase or counter- clockwi

13、se to decrease the output level. IMPORTANT: When connecting two pairs of speakers, determine the impedance of each pair by looking on the back of the speakers, in your owners manual, or by contacting your dealer or manufacturer. You can listen to two pairs of speakers at the same time ONLY if the im

14、pedance of EACH speaker is NOT LESS THAN 8 Ohms. WARNING: Do not play sets of speakers simultaneously except as recommended above. Amplifier may overheat. AC Power Plug the cord into a 230 VAC wall socket. Power indicator will light up to indicate power ON. To completely disconnect the power input,

15、the main plug must be disconnected from the mains. 2 harman/kardonHK 980/230 Service Manual Page 3 of 50 RadioFans.CN 收音机爱 好者资料库 Controls and Functions Speaker 1Speaker 2Source DirectModeSourceRecord Source Volume Phones 980 345678 9 1.

GENERAL DESCRIPTION The OP275 is the first amplif

35、ier to feature the Butler Amplifier front-end. This new front-end design combines both bipolar and JFET transistors to attain amplifiers with the accuracy and low noise performance of bipolar transistors, and the speed and sound quality of JFETs. Total Harmonic Distortion plus Noise equals that of p

36、revious audio amplifiers, but at much lower sup- ply currents. A very low l/f corner of below 6 Hz maintains a flat noise density response. Whether noise is measured at either 30 Hz or 1 kHz, it is only 6 nV/Hz. The JFET portion of the input stage gives the OP275 its high slew rates to keep distorti

37、on low, even when large output swings are required, and the 22 V/s slew rate of the OP275 is the fastest of any standard audio amplifier. Best of all, this low noise and high speed are accomplished using less than 5 mA of supply current, lower than any standard audio amplifier. *Protected by U.S. Pa
