NAD 1600 PREAMPLIFIER/TUNER

The UNSWITCHED outlet should be used to power products involving mechanical operations (e.g. a turntable or tape deck); such products should be switched on and off with their own power switches. The UNSWITCHED outlet may also be used to provide power to a device such as a VCR whose clock timer and digital tuner require uninterrupted AC power to maintain information stored in its memory,

The AC power line cords of other stereo components may be plugged into these accessory outlets. The SWITCHED outlet is intended for all-electronic products (e.g. an amplifier, equalizer, or other signal processor); it is switched on and off by the POWER button. A power amplifier rated at up to 100 watts per channel may be turned on and off via the SWITCHED outlet. If your amplifier is larger than that, use its own power switch to turn it on and off, or plug it into a multi-outlet power-socket strip containing a high-current switch.

1. AC CONVENIENCE OUTLETS (120 V units only)

2. AC LINE CORD. Plug the AC line cord into a "live" AC socket.

REAR PANEL CONNECTIONS

The remainder of the antenna may be allowed to hang down behind the preamp/liner or may be tacked in place horizontally along the rear of a wooden shelf. (If your equipment is installed on metal shelves, they may impair reception; in that case, stretch out the wire along the wall away from the shelf and tack it in place.) You may wish to experiment with the orientation of the AM antenna, in order to find the position that provides the best reception of the stations you listen to most. The short-wire antenna usually will provide satisfactory reception of local AM broadcasts. For better reception of distant AM stations, attach a long-wire outdoor antenna to the AM terminal. As its name implies, a "long-wire" antenna is a straight wire whose length may be anything from a few feet up to about

An external antenna is required for satisfactory reception of AM broadcasts. For local broadcasts a simple wire up to one meter (three feet) in length will provide ample signal strength, and such a single-wire antenna is included with the preamp/tuner. Connect one end of the wire to the AM terminal. Press down the spring tab below the terminal, and insert the bare end of the wire into the terminal. When you release the spring tab, the terminal will grasp the wire. (See Figure 1.)

1. AM ANTENNA TERMINALS.

This unit may be installed on any sturdy, level surface. Since its power transformer generates a magnetic hum field of moderate strength, a turntable (especially one with moving-coil pick-up cartridge) should not be located directly to the left of the amplifier nor directly above it. The preamplifier/tuner requires ventilation. Do not place the amplifier on a rug or other soft surface that it could sink into, obstructing the air inlets on its bottom.

8. MMMC SELECTOR.

This switch sets the input sensitivity and gain of the photo preamble circuit. Set it according to the input level of your phone pickup cassette. Set the output level of the MIMC switch. Begin by setting it to set the switch at MC.Here is another way to determine the preferred setting of the MMMC switch. Begin by setting it to set the switch at MC. After you complete the installation and obtain a statistically loud volume level with a VOL obtain a statistically loud volume level with a VOL-IME control setting between 9 o dock and 3 o'clock. If you have to lamp up the VOLUME control beyond 3 o dock to get adequately loud sound, turn the VOL-IME back down and re set the MMMC switch to MC.9. VIDEO SOUND INPUT.Connect a video-related audio signal here, such as the audio output from a video cassette recorder, video disc player, TV monoracceler, or stereo television decoder. Alternatively, any "line-level" video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as the video signal may be connected here, such as 10.

17. TUNING DISPLAY.This display is in three parts: frequency, signal strength, and tuning.FREQUENCY. The numerical display shows the tuned frequency.SIGNAL STRENGTH. The signal strength meter is a row of five bars below the frequency display. The number of illuminated bars increases with the strength of the received signal. If only one or two bars illuminate, the signal is too weak for noise-free reception in stereo, but reception may be satisfactory in mono. Strong signals are indicated by four or five illuminated bars.TUNING. The center-tuning indicator is located to the right of the digital frequency display. It consists of an illuminated rectangular bar and two triangular pointers. The pointers glow when the tuning is within an FM station's channel but not at the center of that channel. The orientation of the illuminated pointer shows whether the tuning frequency should be increased or decreased. If the arrow points upward, tune to a slightly higher frequency. If the arrow points down, tune to a lower frequency. When the broadcast is accurately centered-tuned, the triangular pointers fade out and only the middle bar is illuminated.At the bottom of the display window is a green LED that glows when remote commands are received. This LED also glows when the unit is in standby mode (plugged in but turned off).18. STATUS INDICATORS.The EPL indicator illuminates when the EPL (external processor) button is engaged.The FM STEREO indicator illuminates when a stereo FM broadcast is received and decoded. Note that if the MONO button is engaged, all broadcasts will be received in mono.If an FM station is broadcasting only in mono, or if a stereo broadcast signal is too weak for rea-

sonably noise-free reception in stereo, then the tuner will automatically switch into the mono mode, and the FM STEREO light will not illuminate. Also, if you have mis-tuned away from the center of a station's broadcast channel, the stereo decoding circuits may not lock onto the signal and it may be received only in mono.19. FM BLEND.The Blend circuit reduces noise in weak FM stereo signals by reducing the stereo separation at high frequencies.It is characteristic of stereo FM that the stereo subcarrier becomes noisler as the received signal becomes weaker. When the Blend is engaged, the contribution of the stereo subcarrier to the sound is reduced at high frequencies, giving up some stereo separation in favor of quieter reception.Disengage the Blend for normal reception of strong signals.20. FM/AM.When the FM or AM button is pressed it switches the preamplifier to the tuner input and selects the FM or medium-wave AM band.21. MONO.The MONO button blends the two stereo channels together to produce monophonic sound. This blend minimizes rumble and surface noise in old monophonic records. Switch the Mono mode off for normal stereo listening.NOTE: If you are making a tape recording, engaging the MONO button may affect the signal being recorded — depending on whether one of the TAPE monitor buttons is also engaged. If a TAPE monitor is not engaged, then pressing MONO will blend the input signal into mono, and the monophonic signal will be recorded. If either TAPE monitor is engaged, then pressing MONO will affect only the sound that you hear as it returns from the recorder; the signal going to the tape will be recorded in stereo.

The MONO button also disables the stereo FM circuits in the tuner. Normally the tuner receives monophonic transmissions in mono and automatically switches on its multiplex decoding circuits when a stereo FM broadcast is received (as shown by the FM STEREO indicator). But when a very weak FM stereo signal is received, it may be excessively noisy because of the multiplex encoding technique used for stereo broadcasting. In that case, press the MONO button to lock the tuner in the mono mode, in order to obtain consistently quieter and cleaner sound.Remember to disengage the MONO button when you re-tune to a stronger signal. As long as MONO is engaged, no broadcasts can be received in stereo.22. MEMORY ENTER.This button engages the Memory Enter mode. Use this mode to enter the frequencies of your favorite stations into the fourteen memory pre-sets (two banks of seven). The procedure is as follows.(1) Decide which station you want to assign to each of the fourteen pre-sets. You may arrange the stations in any order that you find easy to remember or convenient to use.(2) Tune to the first station on your list. Check the center-tune indicator to be sure that you have tuned precisely to the center of the station's broadcast channel.Press the BANK button to select the bank that you want to store the first station in. Press the ENTER button and, within ten seconds, press Pre-set #1 to store the first station in the tuner's memory.(3) Tune to the second station on your list. Press the ENTER button and, within ten seconds, press Pre-set #2 to store the second station.

(4) Continue in this manner and you have stored seven stations in the first seven pre-sets. Then press the BALK button to switch to the second bank of pre-sats, and continue the process for the second group of seven stations. If you make a mistake or change your mind, it is not necessary to re-program the pre-sats in se- quonce. You can re-program any pre-set simply by during to the desired frequency, pressing ENTRY, and pressing the pre-set button that you want to re- program.

24. STATION PRE-SETS You can store the requestcases of fourteen sta- tors in these pre-sats, using the BALK and ENTER bution. Then, to tune those stations from day, just set each appropriate bank and press the de- stand pre-set button. The turn will automatically switch to AM or FM accordingly. The circuit has a "last station used" memory. When the power is switched on it automatically re- tunes to the last station that you were tuned to. the pre-sets preserve their frequency assign- menes when the AC line cond is unplugged, for a period of at least two weeks. This you can re- arrange your stereo system, or move the equipment from room to room, without losing the pre-set tre- quencles. But if you leave the power off for a month or more, you may have to re-program the tming pre- sets. in three buttons in the top row are mode selections: they set (by product category) the remanling buildings.

REMOTE CONTROL

you are recording from FM or CD onto tape, or copying from Tape 1 to Tape 2, you can engage Tape 1 or 2 to monitor the recording, without leaving the CD or Tape control mode. And you can always adjust playback volume, no matter what product you are controlling and what source you are listening to. (Note: in all modes the Volume Up/Down buttons operate the 1600's volume control, not the output level control of a CD player.) Press the Tunet/Amp mode button to operate other controls on the 1600 preamplifier/tuner. The CD mode button performs a dual function: it selects the CD input on the 1600 and also assigns CD. player codes to the keys. To play a CD, simply press the CD mode button followed by PLAY. In the CD mode the Play and Pause buttons have the same effect; each alternates between Play and Pause functions. To hear a tape, press Tape 1 or Tape 2 to hear the output from the tape deck. Then press the Tape mode button to select the recorder control codes in the handset. A remote control can transmit only one command at a time. Commands that require pressing two buttons at the same time (e.g., "punch-in", recording, holding down PLAY while activating RECORD) cannot be executed by remote control. Figures 8, 9, and 10 illustrate which remote control keys are effective in each mode. Each button on the remote control produces the same effect as the corresponding button on the corresponding NAD product.

BATTERY REPLACEMENT It the Transmit indicator (in the upper-right corner of the keypad) does not glow brightly when remote control buttons are pressed, or if the 1600 does not respond to remote commands, the batteries may be weak and should be replaced. The unit requires two 1.5-volt AA-size penlight cells. Alkaline cells are recommended, to obtain maximum operating life. To open the battery compartment, press-down with the thumb at the center of the ribbed area on the back of the remote control unit. The cover of the battery compartment will slide down and off. (See Figure 11.) install fresh AA cells, orienting them as shown on the diagram within the compartment. The coil springs should contact the (-) and of each cell. Slide the battery compartment cover back on until hatches.
