The graph shows the effect of the control (-12 dB/octave). HIGH FILT 1 If the program is accompanied by strong hiss or scratch noise from old and worn records or noise from a tape recorder or from the receiver, depress the HIGH FILT 1 button to obtain moderate attenuation of the high frequencies. The graph shows the effect of the control (--12 dB/octave). HIGH FILT 2 Tins control can be used for the same purpose as the HIGH FILT 1 control, it simply gives less attenuation (--6 dB/octave) as may be seen in the graph. HIGH FILL 1 and HIGH FILT 2 Depressing both these buttons simultaneously gives the heaviest attenuation of all at the high frequencies as may be seen in the graph (-- 1 8 dB/ octave). LOUDNESS At low volume the ear is less sensitive to high and low tones. As a result music at low volume from speakers tends to lack high and low tones and sounds as if it has too much "body" in the middle tone range. To compensate for this effect, depress the LOUDNESS button whereby the bass and t re bl e will be boosted according to the setting of the VOLUME control. The graph shows how this boost increases as the volume is turned down. 11 Headphones Stereo headphones can he connected to the 3-pole jacks marked PHONES on the left side of the front panel and the program level can be adjusted by the VOLUME and BALANCE controls. Two people can listen at the same time if two sets of headphones are plugged in and you can avoid disturbing other people in the room by switching the knob SPEAKERS to OFF. Headphone listening is very convenient for monitoring when recordings are being made, particularly if microphones and loudspeakers are in the same room because it avoids "acoustic howling". Some people also prefer headphones when listening to music. They provide a more intimate listening experience and difficulties associated with room acoustics are avoided. But there are disadvantages, for example the whole sound environment turns with the listener when he moves his head, a feeling regarded by some people as unnatural. This receiver has been designed for use with speakers having a wide range of phase angles i. e. electrostatic as well as moving-coil systems. A good all-round type of loudspeaker which is reliable in design, manufacture, and use is the totally enclosed infinite baffle type. Tandberg produce a full range of this type of loudspeaker. Ask your dealer for details. 13 Combinations of A, B, and C Each stereo channel has three sets of output terminals, A, B, and C. One way of using these outputs is to group two (A+B or A+C) speakers together for each stereo channel. If the speakers for each channel are separated by about three feet this will give a broader front to the stereo effect. Another way of using the outputs is for the A speakers to be in one room, the B speakers in a second room and the C speakers in a third room. This permits full stereo operation in two out of three of the rooms simultaneously, as shown in the figure. The best position for speakers in a room depends upon the room acoustics and the type (or types) of speakers you use. Four basic arrangement are shown in the adjacent figures. [. . . ] Otherwise you may damage your speakers. 21 Monitoring during recording If the tape recorder has separate heads for record and playback, the program can he monitored at the same time as the recording is being made. Two types of monitoring are possible, one is the source test (A-test), the other is the tape test (B-test). The source test is the program before going onto tape and the tape test is the program after it has been recorded on tape. When tape recorders are connected to TAPE 1 and TAPE 2 sockets, the source and tape tests can be carried out on the speakers or headphones on the receiver. [. . . ]
