You are now the proud owner of a Pioneer 4- channel stereo display, model SD-1100. This unit is a multipurpose instrument for observing and measuring various performance characteristics of your 4-channel or 2-channel stereo system and its individual components. Incorporated in this versa- tile units are a four-pole oscilloscope, LEVEL FEATURES DISPLAY OF 4.CHANNEL STEREO SIGNALS ln addition to normal 2-channel stereo signals, the oscillo- scope can be used to show all four signals of a 4-channel system simultaneously, permitting accurate balance and phase checks. DISTINCT, CLEARLY READABLE OSCILLO- SCOPE IMAGE The 75mm (3in.) screen shows a clearly def ined image even of quickly changing signals, and the practical scale on the screen makes various adjustments and readings easy. For extra protection of the screen, a special circuit automa- tically dims the beam when only a spot is displayed, to prevent burning of the phosphorescent layer. EASY.TO READ LEVEL METERS The large, clearly readable level meters on the front panel permit easy readout of various level measurements. The meter range is adjustable in 10dB steps from 20V full scale (+20d8) to 20mV (-40dB) in accordance with the various input terminals of different sensitivity. BUILT-IN AUDIO SIGNAL GENERATOR For frequency response measurements to amplif iers etc., the SD-1 100 contains an audio signal oscillator with frequencies freely adjustable from 2OHz Lo 2OkHz. Set at SWEEP AUTO, the oscillator will automatically sweep over the whole 20Hz to 20kHz band in a cycle of approximately 25 seconds. meters, an audio,signal generator with sweep capa- bility, and a sweep generator. As this unit is rather more complicated in its design and operation than other audiocomponents, please study the following instructions very care- fully and keep the manual at hand for reference. AUDIO SWEEP FACILITY FOR DIRECT OBSERVATION OF FREOUENCY RESPONSE The frequency characteristics of tone controls, filters, crossover networks, loudspeakers, etc. can be observed on the scope, and peaks and dips can be detected. This is possible by utilizing the audio oscillator sweep for hori- zontal scope beam deflection. VERSATILE, EASILY SWITCHABLE INPUTS High level inputs accept comparatively strong signals (as from amplifier's speaker outputs), while low level inputs are provided on the front and rear for low level signals (PRE-AMP out, etc.). lnputs are selected by simple push- button switches. MULTIPLE APPLICATIONS With the built-in signal generator and a good microphone, the overall frequency characteristics of your stereo system and listening room can be measured and tone controls etc. adjusted accordingly for optimum sound. With the Lissajous display facility, phase relations in a 2-channel or 4-channel system can be observed and, if necessary, corrected. Accu- rate balancing is possible with the LEVEL meters. With a test record or test tape, frequency and other characteristics of phono cartridges and tape equipment can be checked the SD 1 100 provides a multitude of uses for scientif ically accurate system checks. FM MULTIPATH DETECTION POSSIBLE FM multipath reception, the greatest enemy of distortion- free FM sound, can be detected, thanks to the special FM multipath input provided. (The tuner must be equipped with a special output.) Thus, the antenna can be precisely positioned for optimum reception. o On or near a power amplifier or transformet, and especially on a vacuum tube type amplifier. o Moist and dusty places. o The vicinity of strong magnets, motors, trans- formers, etc. WHERE TO PLACE THE SD.llOO As the SD-1100 is fully equipped with silicon transistors (except in the cathode-ray tube), it poses no great problems in regard to heat dissipa- tion. However, avoid the following kinds of places: o Direct sunlight and the vicinity of heat sources'
