[. . . ] The antenna is hinged and should be rotated to the position giving the best reception. The ferrite-rod antenna can never perfectly replace a good outdoor antenna. They can also be used to compensate for lack of "body" in any particular tone region with a program from any source. A further use for tone controls is to compensate for speakers and/or room acoustics that do not. give the desired tone picture, Other controls affecting the tone response are LOW FILTER, HIGH FILTER 1, HIGH FILTER 2 and LOUDNESS (see page 11). 9 Stereo-mono switching Stereo-mono switching in the audio amplifiers may be performed for radio, disc, or tape programs by means of the STEREO, MONO L, MONO R, and MONO L+R mode buttons. STEREO button depressed - the two channels are separated for stereo reproduction. MONO L button depressed - the left channel program is fed to both speakers. MONO R button depressed - the right channel program is fed to both speakers. MONO L and MONO R buttons simultaneously depressed -- the two channels are separated for stereo reproduction, with the channels crossed over. This is a twofingered operation because you must prevent the first button jumping out when you depress the second button, MONO L+R button depressed -- the two channels are mixed together and fed to both speakers (this is normal full mono operation). The diagrams illustrate the five possibilities. Use of PRE AMP OUT and MAIN AMP IN sockets The four sockets on the extreme left of the back panel give access to the pre-amplifier outputs and the power amplifier inputs. The receiver will deliver optimum undistorted power when the resultant impedance of all the speakers connected to each stereo channel is between 4 and 8 ohms. Speakers or combinations of speakers with higher or lower impedances will give output powers below the optimum. For load impedances below 4 ohms the output power drops rapidly (see curve). The bottom figure shows some possible speaker combinations for one stereo channel. But only 2 of the outputs (A+B or A+C) can be switched in at the same time. So when calculating the resultant impedance you must take this into account. Polarity Whichever combination of speakers is used it is important to observe the polarity when speakers are in the same room. If the polarity is wrong, one cone will be moving forwards when the other is moving backwards and the result will be a reduction in bass volume. The polarity will usually be correct when each terminal marked with a minus sign (---) on the rear panel of the receiver is connected to the terminal marked COMMON (or NEGATIVE) on each respective speaker. However, reversals of polarity can occur in the wiring between the receiver and the speakers or even occasionally inside the speaker cabinet and one way to be certain is to check the bass volume (under mono conditions with the speakers facing each other about 6 inches apart) and reverse any wrong connections. What type of speaker?This receiver has been designed for use with speakers having a wide range of phase angles i. e. A good all-round type of loudspeaker which is reliable in design, manufacture, and use is the totally enclosed infinite baffle type. [. . . ] Therefore be careful not to release the button when playing at high volume. Otherwise you may damage your speakers. Connect a tape recorder to the TAPE 1 socket or the TAPE 2 socket. button and follow the procedure described on page 21. Three tape recorders involved a) Copying from TAPE 1 to TAPE 2 & TAPE 3. Connect one tape recorder to each of the TAPE sockets and one to the TAPE 3 jack. Depress the 20 Recording on a third tape recorder with or without audio controls If you want to record on a third tape recorder with or without the effect of the audio controls, connect the tape recorder by means of a 3-pole jack plug to the TAPE 3 jack on the extreme right of the front panel, Any program that could be recorded on a tape recorder connected to TAPE 1 or TAPE 2 socket (or both) will now also be recorded on this third tape recorder.
