REAR PANEL CONNECTIONS 1. LINE IN . The NAD 6125 is intended to be connected to I he Tape REC and PLAY (output and input) jacks at the rear of any conventional stereo amplifier. Insert the phono plugs at one end of a stereo connecting cable fully into the LINE IN sockets on the 6t25 . At the other end of the cable , insert the plugs into the TAPE OUT or RECord jacks of the amplifier. Use the color coding of the plugs to identify the channels ; for instance , if one of the plugs at each end of the cable is red, connect the red plug to the R (right channel) socket of both the amplifier and the NAD 6125. 2 . LINE OUT . To play tapes, plug one end of a stereo connecting cable into the NAD 6125's LINE OUT jacks, and plug the other end into the TAPE IN, PLAY, or MONitor input jacks of the amplifier. Make sure that each plug is inserted fully into its socket, and observe the color coding of the plugs to ensure that the stereo channels are connected consistently . 3. AC POWER CORD. Connect the AC power cord to a convenient wall outlet or to an "unswitched " AC convenience outlet at the rear of your amplifier . A note on fnstallatlon. The excellent performance of the NAD 6125 stereo tape recorder depends on an array of precisely machined parts, fine bearings , smoothly polished surfaces, sensitive detection of the weak magnetic fields in tape recordings, and amplification of very small signal volt ages . Consequently the recorder's performance can be adversely aHected by external magnetic fields, electrical in terference, vibration, heat , mOisture, or chemical fumes . Thus if it is placed directly on top of a power amplifier, the 6125 may pick up a low-frequency hum from the ampli fier's power transformer. If you wish to install it next to an amplifier on the same shelf , place the 6125 on the left so that its cas sette compartment will be located away from the amplifier . The 6125 should not be placed on a loudspeaker or on a television set (a source of strong magnetic fields as well as vibration), nor in direct sunlight, nor very close to a steam radiator, nor in a workshop where metal filings and chemicals are found . The 6125 will function best at temperatures that are comfortable for people, and it can be stacked or shelved with the remaining components in your stereo system. If you are located near a powerful television or radio transmitter (including a citizen 's band or short-wave unit) you may pick up interference, especially when playing previously recorded tapes. If you encounter this type of radio-frequency interference, you may succeed in reducing it by experimenting with the location and orientation of the recorder. If the problem perSists , your dealer or a service shop may be able to add approved circuit modifications or extra internal shielding. Connecting two recorders. Some stereo amplifiers have two sets of tape inpuVoutput jacks, with front-panel switching ~ e lightning flash with arrowhead , w i thin an eqUilateral lriangle, is intended to alerl the user of the presence of uninsulated "dangerous voltage" within the product's enclo· sure ; that may be at sufficient magnitude to constitute a risk of electric shock to persons . 3 to permit using either of two tape decks for recording or playback and to permit copying tapes from one to the other . If your amplifier has only one set of connections for a tape recorder , it is still possible to use two recorders with it. The most convenient and flexible method is to purchase an exter nal sWitch-box (Tandy Radio Shack #42-2105 or equivalent), which will provide inpuVoutput connections for up to three re cor ders and allow copying among them. The alternative methods described below are less flexible, but they cost less and yield equally good recordi ngs. Copying. Connect the "copying" recorder (the machine on which the new copy will be recorded) to the amplifier's TAPE recording /playback jacks as described above. Then connect to the amplifier's AUXiliary input a cable from the Line Output jacks of the "source" recorder (the machine containing the tape that you want to copy), and switch the amplifier's Input Selector to AUX. If an AUX input is not available, an alternative procedure is to disconnect the cable from the amplifier 's tape RECord ing output , and connect the "source" recorder 's Line Output directly to the copying recorder's Line Input. With this con nection you must activate the copying recorder's RECORD function in order to monitor the playback output of the source machine . Parallel recording . Two recorde rs can be wired in par allel to permit simultaneous recording on both. Obtain two "V connector" adapters, each having two female phono sockets and one male phono plug (e.g ., Tandy Radio Shack #42-2436 or equivalent) . Plug one V-connector inlo the Right channel Tape RECording jack of the amplifier , and connect the Right channel (red) plugs of two stereo cables to the V-connector 's two sockets . Plug the other V-connector into the Left channel Tape REC jack, and connect the left-channel plugs (usually black) of the two stereo cables to the V-connector's sockets. Finally, at the opposite end of the two stereo cables , connect to the Line Input jacks of the two recorders . This hookup allows you to reco rd freely on either ma chine, or simultaneously on both, but not to copy tapes from one to the other . NOTE: This method of parallel connection works well for recording, but not for playback. If you use V-connectors to combine the Line Output signals from two tape decks , each machine's output will tend to short-circuit the other's, yielding a low playback level and possibly higher distortion. Only one tape deck's Line Output signals can be fed to the amplifier's Tape PLAY input jacks. To hear the playback from the second recorder, connect its Line Output to the amplifier's AUX input . But observe this precaution : never switch the amplifier 's Input Selector to AUX while recording on the machine whose output is connected to AUX; doing so would create a feedback oscillation that could damage your loudspeakers . ~ e exdamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance .
