Connections Switch the power to all components OFF. Then use the supplied shielded cables with RCA-type plugs to establish connections as shown in the chart. As this deck has only line input facilities, a separate microphone mixer with line-level outputs must be used for microphone recordings. Connect the out- put of the mixer to the deck's “Line Input” jacks. Nakamichi offers the optional MX-100 Microphone Mixer, which provides three microphone inputs. To power the MX-100, the separate PS-100 Power Sup- ply is required. System Remote Terminal (CR-2) This terminal can be connected either to the wired remote contro! unit RM-5 or a Nakamichi compo- nent equipped for system remote control (such as the CA-7). For details please refer to the Owner's Manual of the respective component. Helpful Hints * This cassette deck incorporates a muting circuit which operates for about 4 seconds after the power was switched on. During the muting in- terval, the tape transport buttons are inactive. e |fthe power to the deck is switched off while the tape is running, it may not be possible to open the cassette holder. Do not apply excessive force in such a case. Set the Timer switch to “Off,” and then switch the power to the deck back on. The cassette can now be removed. * For reasons of reliability and performance, C-120 cassettes are not recommended for music recording. * Cassette tapes have tabs to prevent accidental 13.

To restart the tape from the pause mode, press the Play button. With this deck, the record/pause (recording standby) mode is activated simply by pressing the Record button. O Tape Selector Before recording, the correct button must be pressed for the tape in use. The EX (I) button is for normal- type tapes, the SX (ll) button for chrome-type tapes and the ZX (IV) button for me- tal tapes. In playback, the Tape Selector has no effect and can be set to any position. © Eq Switch This switch serves to select the proper equali- zation for each tape in recording and playback. In regular use, normal-type tapes should be used at the 120 us position and chrome-type and me- tal tapes at the 70 us position. Ás the Eq and Tape Selectors are separate on Nakamichi cas- sette decks, different combinations to suit spe- cial requirements are also possible.

Playback must be car- ried out at the same setting as used in recording. The Dolby NR indicators show which system is selected. O MPX Filter Switch This switch serves to suppress remnants of the 19-kHz multiplex carrier signal, which could in- terfere with proper Dolby NR operation when recording from FM stereo broadcasts. Most modern tuners incorporate filters which reliably remove the carrier, so that problems during recording are unlikely, even when the MPX Filter switch of this deck is set to “Off.” If an audible degradation of the recorded sound is noticed, set the switch to “On.” O Output Level Control (CR-2) Serves to adjust the line output and headphone listening level. O Rec Level/Balance Controls The inner knob of this concentric control adjusts the input level and the outer knob the left/right channel balance during recording. Except when there is a noticeable left/right level difference in the program source, only the Rec Level control needs to be adjusted. Сыйу МА MFE Filter = On 0 BIC.

This is use- ful to insert blank spaces between selections. O Memory Stop/Repeat Switch This switch has two functions. Memory Stop (left position): When the switch is in this position, the tape stops automatically during fast-forward or rewind when the zero point of the tape counter is reached (CR-1: during re- wind only). By resetting the counter to zero at a specific location, that point can be easily found afterward. Auto Repeat (right position): Setting the switch to this position during playback, recording, fast- forward or rewind activates auto repeat. When the tape end is reached, the cassette is auto- matically rewound and playback starts again from the beginning. In this way, playback of the current cassette side is automatically repeated. ® Tape Counter Shows the tape position in four-digit numbers. Pressing the Reset button returns the indication to zero. * The tape counter of the CR-1 has three digits. ® Eject Button Press to open the cassette holder. English Playback ml неее нее еее не 8 ке.

Timer Recording or Playback By using a separate audio timer, unattended record- ing or automatic playback can be easily carried out. Be sure to set the deck’s Timer switch to “Off” when this feature is not desired. If the switch is left in the “Rec” or “Play” position and power to the deck is turned on, the respective function will be activated and an inserted cassette may be erased inadver- tently. 1. Set up the amplifier, tuner etc. as for normal recording or playback. Then set the Timer switch of the cassette deck to the desired function (“Rec” or “Play”). 2. Setthe timer to the desired switch-on and switch- off time. 3. At the pre-selected time, the timer will supply power to the components and recording or play- back will start automatically, Adjust the Output control to obtain the desired volume level. Pressing the Play button in this condition starts recording. For short-term interruptions, press the Pause button. The deck reverts to the record/pause condition. To resume recording, press the Play but- ton again.

However, even tapes of the same general type often have slightly different bias re- quirements. The Bias Tune control of the CR-2 offers the possibility to compensate for such differ- ences. This adjustment is not mandatory; satisfac- tory recordings can be made while leaving the control in the center click-stop position. But in order to extract optimum performance from every tape, adjust the control as follows. Record a source such as interstation noise from an FM tuner at a level of about —30 to —20 dB. Re- wind the tape, play back the recorded section and compare the sound to the original input signal. If the recording sounds brighter than the original, turn Record Level Setting Correct record level setting is an essential aspect of tape recording. To achieve optimum performance from both the cassette deck and the tape, some at- tention should be devoted to this point. Nakamichi recommends setting record levels as high as possible without running into distortion. If record levels are too low, tape noise may become audible, and natural demagnetization (reduction in recorded signal strength over an extended period of time) can become a problem. When combined with a high-performance cassette tape, the high dy- namic range of Nakamichi decks permits “pushing” the tape close to its saturation limit without degra- dation of sound quality. Independent Eq Switch The regular equalization is 120 us for normal-type tapes and 70 us for chrome-type and metal tapes. As this deck provides separate switches for equali- zation and tape type, other settings are also possi- ble, such as 70-microsecond equalization for normal-type tapes, or 120-microsecond equalization for metal tapes. Provided that the same position is used in playback, this will also yield flat frequency response. the Bias Tune control clockwise. If the recording sounds less bright than the original, turn the con- trol counterclockwise. Repeat this process a few times, to minimize any differences in sound quali- ty. FM interstation noise is suitable for this purpose, as it contains a wide and fairly even spectrum of frequencies from the low to the high range. As the setting of the Bias Tune control affects the high-range frequency response, it can also be used to tailor the sound to suit certain types of music or personal preferences. However, extreme settings will lead to increased distortion and should be avoided. * The Bias Tune control operates only during recording; it has no effect during playback. Center click-stop position Bias| Tune High-frequency response rises (bias current is decreased) High-frequency response drops (bias current is increased) Record level setting (using recommended tapes) Metal tapes: Normal-type tapes, chrome-type tapes: Signal peaks should be allowed to register up to +3 dB. Signal peaks should be allowed to register up to +7 dB. The optimum recording level varies to a certain degree, depending on the tape in use and the recording source. As a rule of thumb, the peak lev- el meters should be allowed to read up to +7 dB 1. Using a normal type tape at 70 ps reduces noise by about 4 dB, but the high-frequency MOL (maximum output level) will decrease slightly. This may be preferable for example for record- ing classical music which usually contains rela- tively little high-frequency energy but demands high signal-to-noise ratio. with metal tapes and up to + 3 dB with chrome-type and normal-type tapes (when using tapes recom- mended by Nakamichi). 2. Using a chrome-type or metal tape at 120 us causes a slightly higher noise level, but upper- range MOL also increases. This is suitable for example for jazz or rock, where average levels are high and strong high-frequency peaks are often encountered. * In both cases, it is essential to use the same po- sition in playback to ensure flat frequency response. English Cleaning It is very important to regularly clean the head sur- faces, capstans, pressure rollers, etc. Contamina- tion caused by tiny particles shed from the tape onto these parts can become the cause of dropouts and severely degrade high-frequency response and wow-and-flutter characteristics. Perform cleaning about once every 10 hours of use. Cotton swabs lightly moistened with zero-residue, fluorocarbon- based fluid are an economical, effective and safe tool for this task. * The head assembly, tape guides and other parts of this deck’s tape transport are critically aligned. Be careful not to apply too much force during cleaning. Demagnetization After a longer period of use, residual magnetism can build up in the heads and capstans, which leads to noise and can partially erase the high frequencies of a tape being played. To prevent this, you should demagnetize these parts about once every 50 hours of use with the Nakamichi DM-10 demagnetizer (op- tional) or any other properly designed demagneti- zer. For details, please refer to the instruction manual of the demagnetizer.
