A record player with MM cartridge must be connected to the Phono Input jacks and a separate ground wire to the ground terminal scr

11、ew above. Wired Remote Control To control your amplifier with an external infrared remote sensor, connect the wire from the remote sensor to the REMOTE IN jack on the back panel. Or, if another stereo component has a built- in infrared remote sensor and a Remote Output jack, it may be possible to co

12、nnect 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 experiment.

13、 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 c

Avoid rolling excess wire with or near signal interconnects. External Power Amplifiers For applications where higher power is

15、 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- clockwise

16、 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 impe

17、dance 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, th

25、r, CD Recorder or CD Player, the appropriate input (”TUNER”, ”CDR” or ”CD”) must have been selected with the source buttons of the remote control (selecting on the front panel is not sufficient). Note that DVD players or tape decks cannot be controlled by the remote. To control a compatible CD Recor

26、der ”CDR” must be selected as input and the drive to be controlled (CDP or CDR) must be selected appropriately with the ”CDP SELECT” or ”CDR SELECT” buttons. Operating Conditions The control unit operates effectively within a distance of 7 meters and an angle of 30 from the amplifier. Using the cont

Also avoid blocking the line of sight between amplifier and remote. The control unit is powered by two AA batteries, included w

Input off-set voltage is guaranteed at 1 mV and is typically less than200 V. This allows

47、the OP275 to be used in many dc coupledor summing applications without the need for special selectionsor the added noise of additional offset adjustment circuitry.The output is capable of driving 600 loads to 10 V rms whilemaintaining low distortion. THD + Noise at 3 V rms is a low0.0006%.The OP275

48、is specified over the extended industrial (40C to+85C) temperature range. OP275s are available in both plasticDIP and SOIC-8 packages. SOIC-8 packages are available in2500 piece reels. Many audio amplifiers are not offered inSOIC-8 surface mount packages for a variety of reasons; how-ever, the OP275

49、 was designed so that it would offer full perfor-mance in surface mount packaging.GENERAL DESCRIPTIONThe OP275 is the first amplifier to feature the Butler Amplifierfront-end. This new front-end design combines both bipolarand JFET transistors to attain amplifiers with the accuracy andlow noise perf
