YAMAHA offers you thanks and congratulations on your choice of the CR-2020 Receiver. Embodying novel and useful features, it combines super broadcast reception with the finest audio quality, and is currently setting new standards for receiver performance tn ils class. SPECIAL FEATURES OF 1. All-in-One Excellence Accurately matched performance specifications, functions, and controls, give overall performance which fully measures up to Yamaha's high tuner, per-, and power amp standards, 2.
?/7[ AUCTIONS — READ THIS BEFORE OPERATING YOUR CR-2020 1 The CR-2020 is a high performance AM/FM stairs receiver, with excellent selectivity, sensitivity, low distortion, and high output power. This manual is required reading if you are to get the best from its special features and controls. 2 Do not drop or other wise jar the CR-2020, which is & precision electronic instrument.
POWER DOFF Switch Switch ON to connect the main electrical supply. eave OFF while familiarizing yourself with the controls, and while connecting other audio equipment. & VOLUME Control Use this control to give the volume of sound that you require. Always start with it turned fully to the left {counter-clockwise} at the 'O’ position before turning it up to the volume level you retiree. B BANDAGE Control This controls the balance between the L and R stereo channels.
$ PM TUNING METER This is used when tuning in FM stations! the indicator points to dead center when the station is perfectly in tune.
REAR PANEL AND CONNECTIONS O SPEAKERS Terminals The complete instructions for connecting speaker sterns to this receiver are given on page 14, However, if you wish 1o hear what your receiver sounds like now, you can hook up your speakers to the A terminals on the rear of your CR-2020. Only use speakers with impedance between 8 and 18 ohms, and preferably rated to take 100 Watts. if not, use the VOLUME control so that their rated maximum input power is not exceeded on the meter readings.
6 DOLE FV ADSORPTION Terminals 1 you purchase an adapter designed to enable you 10 receive Dolby FM broadcasts, it should be connected to these terminals, and the corresponding switch on the front panel should also be depressed during Dolby FM broadcasts. 6 PRE OUT and MAIN IN Terminals The preliminary section output is always available from the PRE OUT terminals, but unless the COUPLET switch is OFF, the output from another amplifier cannot be fed to the power (MAIN} section.
BROADCAST RECEPTION ! CONNECTING AN EM ANTENNA The T-type antenna provided is adequate only in high signal strength areas under favorable conditions. In other cases, an external multi-element FM antenna is needed. 1 you cannot obtain satisfactory reception with the T-type antenna after trying it in different positions, end orienting it to give the best reception for the weakest station to which you will normally be listening, this is an indication that you need an external FM antenna.
e 1. Set the INPUT SELECTOR @ to TUNER, and the TUNER push-button to FM. Note that the FM indicator at the left of the tuning scale is lit. 2. All other push-buttons should be fully OUT {i.e. non-depressed} and the switches and knobs should be in the settings shown in the fold-out diagram of the front panel. 3. Touch the tuning knob and note that the OUTSTATION tight goes out. Also the central renter will revert to its SIGNAL Q function. 4.
FM STEED OFF SIGNAL further reduction is noise ié desirable, press the FM MUTING push-bunion to the OFFENBACH position. You will be able to receive weak stations with the Lowest possible noise feels, but as the name of the switch indicates, only in the monaural mode. And although the on-station noise will be reduced, you will notice much more ‘static” interference between stations. This inter station noise is normally blanked out by the muting circuit when ON.
BTl 1f you purchase a suitable ‘FM DOLBY’ adapter designed to make the best of DOLBY-type broadcasts, it should be plugged. into the appropriate pin-jacks on the rear pane, and the switch on the front panel should be pushed in. Leave it OFF {out} i you do not have an adapter: mistakenly pushing it ON will prevent normal audition of FM programs. BT 1. Set the TUNER FM/AM switch to AM. 2. Set the tuning indicator to the station frequency. 3. Adjust the tuning knob to give the maximum SIGNAL mater reading. 4.
SPEAKERS AND HEADPHONES JL SPEAKERS A e 8 PHONES ON-OF SPEAKERS : The CR-2020 can handle three sets of speakers (A, 8, and Cl, with selection of any one or two sets by the SPEAKERS switch on the front panel, The CR-2020 is designed for speakers with impedance between 8 and 16 ohms when connected o either terminals. If two sets are to be played at the same time, however, please use only 18 ohm speakers.
T The main AC supply plug of your turntable unit may conveniently be inserted into the spare AC outlet socket controlled by the CR-2020 POWER switch. The output lead from the turntable unit should be connected to the PHONON 1 terminals, keeping the PHONON 2 terminals as spares, Check that the L and R pin plugs have been correctly inserted.

RN : AND POWER: SECTIONS = After the program signal has passed through the tone, filter, and volume controls it is fed 16 the power amplifier section, At the same time, it also appears at the PRE OUT terminals on the rear panel, where it is always available to drive a second power amplifier, or for connection to an oscilloscope or electronic frequency divider unit, etc. This is true whether the COUPLET switch is ON or OFF.

Use the TAPE 1 ter finals for your main deck. Use the TAPE 2 terrains for a second deck or as a spare pair. Set the INPUT SELECTOR to TAPE 1 to play back tapes {or to TAPE 2 if you are using the TAPE 2 terminals, of course}.
monitoring i impossible; most open-reel decks da have three heads, with one for monitoring.) The level at which a recording is made Is very important {see the instruction manual provided with your tape recorder). Adjustments in level should normally be made with the input levee controls on the tape deck. The GR-2020 tone, filter, and level controls are only operative for the PRE OUT position of the REC QUT switch.
LID a Pine GdB o AUGHT MUTING U b L NUMBNESS 20 Ry e The CR-2020 features ganged volume controls in positions both before and after the tone-control circuits, in both channels, a total of four precision ganged vole controls in all. This gives a considerable gain in signal-to-noise ratio at normal listening revels, as shown in the graph. The vertical arrows show the gain over conventional volume controls.
First turn the LOUDNESS contort fully clockwise to the FLAT position, then adjust the main volume control to the maximum listening feel you will normally be using. Make any further adjustments to the tone controls at the maximum level. Then use the LOUDNESS control, rather than the main VOLUME contra itself, to reduce the listening feel when necessary. The same tonal balance wit be preserved at all levels. i These meters enable you to read the output power labels of the CR-2020.
TURNOVER FREQUENCY eon o con TR i TONE CONTROL Tour PETROL o . i peewee TONE CONTROLS in addition to the normal bass and treble controls provided on most amplifiers and receivers, there is a special PRESENCE control for the mid-range frequencies. The bass and treble controls, too, Have twin turnover frequencies, so that the degree of tone control possible with the CR-2020 is unusually large. Be sure to depress the DEFEAT button (to the ON position) or these controls will not function.
FILTERS AND MODE SELECTION The filter circuits of the CR-2020 offer an unusually wide range of filter functions, combining a choice of two frequencies each for high and low cut-off, with very steep cut-off attenuation slopes {a full 12 dB/octave).

Before assuming that your CR-2020 is faulty, check the following trouble-shooting fist, which details many steps TROUBLE SHOOTING you can take yourself, without having to Cali a service representative. AUDIO SECTION LED unlit} Cause Cure AC power fine not plugged into supply socket. AC main fuse has blown, Plug firmly into the supply socket. Contact your service rep. for a replacement. Ko sound although power is contented. Volume too law. INPUT SELECTOR in wrong position.
TUNER SECTION Fault Cause Cure A persistent hum recurs when an AM station is tuned, This modulation hum can affect whole areas where conditions are unfavorable. Sometimes changing the position of the CR-2020 will give an improvement. intermittent crackling or continuous background ‘roaring’ on AM. Atmospheric electricity or electrical storms; possibly fluorescent lighting or other electrical equipment.
