User manual NAD 613

[. . . ] Note to CATV system installer: This reminder is provided to call the CATV installer's attention to Section 820-40 of the NEC , which provides guidelines for proper grounding and, in particular, specifies that the cable should be connected to the grounding system of the building, as close to the point of cable entry as practical. Some models are designed for use only with the power supply voltage of the region where they are sold. The lightning flash with arrowhead, within an equilateral triangle is intended to alert the user of the presence of uninsulated "dangerous voltage" within the product's enclosure; that may be of sufficient magnitude to constitute a risk of electric shock to persons. The recorder may be installed on any stable surface that is not subjected to vibration or intense magnetic fields. [. . . ] This button, when pressed together with either the PLAY or PAUSE button, will activate the recording circuits. The "Record" annunciator with either play or pause icon will light up in the display. By pressing PLAY in combination with RECORD, the recording will start immediatly; by pressing PAUSE with RECORD only the recording circuits will be activated. Now the "Record" annunciator together with the play icon in the display will light up to indicate the recording status. Set the DOLBY NR (17) selector to the desired type of noise reduction (no noise reduction; OFF, B or C). Refer to the chapter "How to get the best performance from your NAD 613 cassette deck", section "The Dolby NR noise reduction systems B & C" for more detailed information. Press the RECORD (10) button together with the PAUSE (7) button; the red annunciator and pause icon in the display will light up. Refer to chapter "How to get the best performance from your NAD 613 cassette deck", section "Recording level" for more information. If you wish to interrupt a recording whilst keeping the recording circuits and display active, press the PAUSE (7) button. This technique is useful for omitting announcements or commercials when recording from radio or television. The recording balance between left and right channel can be adjusted using this control. Refer to chapter "How to get the best performance from your NAD 613 cassette deck", section "Recording level" for more information. The Bias tuning control allows you to compensate for almost any brand-to-brand difference in tape sensitivity and frequency response. Turning the control clockwise will decrease treble (more Bias), turning it counter clockwise increases treble response (less Bias). Normally this control should be at the "0" position (centre detent). Refer to chapter "Getting the best performance from your NAD 613 cassette deck" section "Bias control" for more information. Play Trim is a special play-back equalisation circuit to restore accurate play-back response from prerecorded, old and worn tapes, tapes recorded in another deck, tapes which weren't recorded properly (too much or too little bias). This control will allow you to adjust the deck's circuitry to ensure proper Dolby NR tracking for a correct high frequency response. Refer to chapter "Getting the best performance from your NAD 613", section "The Play Trim control" for more detailed information. The NAD 613 is equipped with two repeat modes; repeat the entire side of a cassette or repeat a preselected block 5 times. Select FULL (either from stop or during playback) to repeat the entire cassette. When you have reached the end of the block you wish to repeat, press the REWIND button (8). [. . . ] Dirt, dust and tape-oxide can potentially damage the heads and tape guidance, besides degrading the sound quality both on play-back and recording. Parts in direct contact with the tape therefore need to be cleaned regularly. NOTE: Make sure the receiver or amplifier is switched off before cleaning or demagnetising the heads. Whilst making a new recording any previous recordings already on the tape will automatically be erased. [. . . ]
