PIONEEIII' 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 versatile units are a four-pole oscilloscope, LEVEL meters, an audio,signal generator with sweep capability, 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 carefully and keep the manual at hand for reference. FEATURES DISPLAY OF 4.CHANNEL STEREO SIGNALS ln addition to normal 2-channel stereo signals, the oscilloscope can be used to show all four signals of a 4-channel system simultaneously, permitting accurate balance and phase checks. DISTINCT, CLEARLY READABLE OSCILLOSCOPE IMAGE The 75mm (3in.) screen shows a clearly def ined image 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 horizontal scope beam deflection. VERSATILE, EASILY SWITCHABLE INPUTS even of on the screen makes various adjustments and readings easy. For extra protection of the screen, a special circuit automatically dims the beam when only a spot is displayed, to prevent burning of the phosphorescent layer. 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- EASY.TO READ LEVEL METERS MULTIPLE APPLICATIONS quickly changing signals, and the practical scale The large, clearly readable level meters on the front permit easy readout of various level measurements. The meter range is adjustable in 10dB steps from 20V full panel 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 audio signal oscillator with frequencies SD-1 100 contains an 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. button switches. 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. Accurate 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 distortionfree 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. 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 dissipation. However, avoid the following kinds of places: o Direct sunlight and the vicinity of heat sources' 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 formers, etc. magnets, motors, trans- EXAMPLE FOR USE 2.CHANNEL STEREO DISPLAY (For details. ssg page 12.)

Then remove the fuse plug from the unit. Put the fuse plug back so that the proper line voltage marking can be seen through the cut in the edge of the plug. Whenever the position of the selector is changed, check the rating of the fuse. A 0.5-ampere is to be used for either 220Y or 240V operation and a 1-ampere fuse for 1l-0V, 120V and 130V operation. If the rating of the fuse is correct, replace cap. FUSE REPLACEMENT If the fuse blows, remove the fuse cap and replace the fuse with a new one (Fig. 2). @-ffi "ol,* FUSE CAP FUSE FUSE PLUG SOCKET Fis.2 t PI()NEEfiI BEFORE USE, PLEASE OBSERVE: o INPUT TERMINALS There are two pairs of inputs on the front panel, four pairs on the rear panel. The FRONT-REAR switch selects the inputs-it has nothing to do with ,,front,' and ,,rear" channels stereo system (See Fig. 3). The AUDIO INPUTS on the rear panel are divided into LOW and HIGH (-20dB). These must be chosen according to the applied signal level, and switched with the LOW/HIGH SELECTOR. CRT PROTECTOR CIRCUIT As a constant, singie spot beam could eventually affect the o phosphorescent material on the CRT screen, a special protector circuit dims the beam whenever the vertical and horizontal deflections are both smaller than 10mm. Thus, the beam may dim during a pause in the music when the scope is used to display a Lissajous pattem. o THE LEVEL METERS When meter deflection is too small for accurate reading, meter sensitivity can be increased by setting the meter switch at -10, -20 or -30d8. The meters will then indicate 10, 20 30dB more than actual signal level. Be very careful, however, not to let the meters deflect to the right edge as this might eventually damage them (See Fig. 4). . THE OSCILLATOR FREQUENCY CONTROL When tuming the oscillator frequency control knob very rapidly in either direction, the signal may sometimes stop completely. This is no indication of a defect but is due to the CdS element in the circuit. In such a case, turn the knob to SWEEP AUTO position once, then turn it slowly to the desir_ ed frequency.

If the frequency response of the measured cartridge is flat, the CRT screen will show a pattern as in (A) of Fig. 28; if the frequency response is rising towards the high and low ends, the pattern on the screen will be like(B);and if the frequency response drops off at both the high and low ends, the screen will show a pattern like (C). CHECKING TRACKABILITY Provide the same connections as for checking of frequency response, and play a trackability test record. If the CRT screen shows such patterns as in Fig. 29, it indicates that the car- tridge isn't tracking properly. CHECKI NG CHANN EL SEPARATION Provide the same connections as for checking of frequency response, and play a channel separation test band of the test record. 1. Set the FUNCTION SWITCH to DISPLAY 2CH, and depress the WAVEFORM & DISPLAY SELECTOR SWITCH 1 and the DISPLAY SWITCH 3. 2. With the above settings, the LEVEL METER (VERT) will indicate the level of the left channel signal; and the LEVEL METER (HORIZ), the right channel signal level. 3. The difference between the reading on the LEVEL METER (VERT) and that on the LEVEL METER (HORIZ) is the channel separation of the tested cartridge. For instance, if only a left channel signal is present, and the LEVEL METER (VERT) indicates - 2dB and the LEVEL METER (HORIZ) indicates - 20dB, the channet separation of the cartridge at the given frequency is 18dB. i.e. channel separation (- 2dB) - (- 20dB) = 1SdB. Fis. zg Fis. 2g zo OBSERVATION OF FM MULTIPATH RECEPTION FM signals are reflected from objects such as large buildings or hills, etc. and arrive at the antenna from many directions. The signals sometimes become distorted. If multipath reflection can be checked, this type of distortion can be eliminated or minimized by repositioning or changing the antenna. If an FM tuner provided with FM multipath terminals is available, FM multipath reflection can be checked by the following steps. 1. Connect the MULTIPATH OUTPUT terminal of FM tuner to the FM MULTIPATH INPUTS of the SD-1100 with the supplied cord. Note that the upper jack of the FM MULTIPATH INPUTS of the SD-1100 is for vertical (VERT) and the lower jack is for horizontal (HORIZ) as shown in Fig. 30. 2. Set the FUNCTION SWITCH to FM MULTIPATH. 3. Adjust the amplitude of the pattem on the screen by controlling the VERTICAL GAIN KNOB and the HORI- ZONTAL GAIN KNOB. 4. Select an FM station which is located far from your area and tune in to the station at the time an announcement is being made. 5. If there is no multipath reflection, the screen will show a straight horizontal line as in (A) of Fig.31. If there is much multipath reflection, the screen will show various patterns as in (B). Reposition or redirect the antenna so that the pattem on the screen becomes as close as possible to a straight line. sD-1 100 l_@J tar t(]ffiijl MEE+::F \:J7l tel q.Fg€l oe {leq e,_9 REAR PANE L OF SD-1 1OO -H;:* 6@ oHEl 666ffi1 oa T R A-.,JI N FM MULTIPATH OUTPUT IilJlI '"1 Fis. so (A) ANTENNA DIRECTION IS GOOD.
