5 . 1 E O U A L I Z E RA M P L I F I E R The circuit diagram for the equalizer amplifier is shown in Fig. 1. The two separatephono inputs are selectedby the FUNCTION selector on the front panel. The input resistance and input capacitance can both be adjusted to 4 different levels(R=l0kCl, 25kO, 50kA and 100kO, C=1-00pF, 200pF, 300pF and 400pF) by means of the CARTRIDGE LOAD control knobs (R and C) which switches in and out, additional resistors and capacitors in parallel with the input terminal. Hence, optimum load conditions for different phono carbridges can be adjusted, as well as modifying the cartridge's frequency response in the high frequency range and thus producing variations in its characteristics. The first stageof the equalizer amplifier (Q, & Qr) is a differential amplifier using PNP transistors. The next stage (Q.) is a bootstrap circuit employing C1, R1 to provide high voltage gain. The output stage (Q+ & Qr) is a complementary-symmetrical SEPP circuit, whose high voltage utility factor results in a high output voltage. This gives the equalizer amplifier a very wide dynamic range, and a considerable overload input level of 300mV (RMS at lkHz) with no more than 0.05V"distortion. The equalizer elements (Cr, Cr, Rz and R3) consist of polypropylene film capacitors (tolerance !2Vo) and metal film resistors (tolerance xIVo). Phono equalizer RIAA deviation has been reduced to less than t0.2dB (20H2 - 2OkHz\.
5.2 TONE CONTROLS The SA-9500 II features two sets of tone controls (Tkin Tone Controls) with different turnover frequencies for bass and treble. And each of these controls may be used independently. Incoming signals are amplified to the required level by the 2 stage amplifier which uses a differential amplifier at first stage. T\vo tone control circuits (C-B feedback NFB type) are connected together in series. The second stage is the normal tone control (MAIN), while the other is a seeondary tone control at a different turnover frequency (SUB). On the TREBLE side, this (SUB) tumover frequency is higher than the MAIN, while on the BASS side, it is lower. The basic principles of the NFB type tone control circuit are outlined in Fig. 2.

Midrange Operation The Cr and C2 reactancesare considerably smaller than VRr at frequencies above midrange, effectively shorting VRr. At frequencies below midrange, C. reactance becomes large and in effect, opens the circuit. Consequently, the circuit becomes equivalent to that shown in Fig. 3 with respect to the midrange. In this figure, the circuits parameters are not changed by any change in position of the VRr and VR2 sliders.The NFB amount is therefore fixed and the circuit gain is also fixed without regardto VRr and VRz slider positions.

Tone Defeat Circuit By setting the TONE switch to OFF, the above describedtone control circuit becomesbypassed. 5.3 POWER MPLIFIER A The circuit diagram for the power amplifier section is shown in Fig. 6. The input stage (Q,) constitutes a differential amplifier, employing a dual transistor (a 2-in-1 transistor "package" possessingthe functions of 2 separate transistors). The second stage (Qr, Q.) is also a differential amplifier, but with the inclusion of a current mirror (D,, Qo). Since the Qa baseemitter junction corresponds a diode, the potento tial on the anode of D1 and the emitter of Q+ will be the same. Consequently, the potential drops across R' and R2 will also be equal. So if the resistanceof these 2 resistorsis the same,the same current will flow through both sections. And if the hpE of the transistor is sufficiently large, the base current can be neglected. That is, the Q2 collector current and the Qo collector current will be the same. Since Q2 and Q3 operate out of phase with each other, Q3 and Qq will operate as a push-pull amplifier. The bias voltage for the power stageis supplied by the potential difference produced across the VR,-D1, where VRl is the variable resistor used to set this potential difference. D2 is a varistor which compensatesfor thermal differences. The power stage (Qr-Q,o) includes a 2-stage Darlington connection, with the final stage (Q7Qro) forming two complementary symmetrical parallel circuits. The output mid-point is maintained at 0V by a balanced plus and minus power supply and a LOOTo NFB circuit. DC

Low Frequency Operation The reactance of C, and C, increasesat low frequency to form a circuit as shown in Fig. 4. This reactance increasesin proportion to the frequency declines. Also, the NFB amount varies greatly according to VRr slider position. The circuit gain at low frequencies can therefore be varied by VR1.

High Frequency Operation The considerably smaller reactance of C1 and C, at high frequency in comparison with VR1 effectively shorts VRr to from an equivalent circuit such as that shown in Fig. 5. C3 reactance decreasesin the same degree that the frequency increasesand the NFB amount is now mainly controlled by the VR2 slider position. Consequently, the gain at high frequenciescan be varied by VR2.

5.4 PROTECTION IRCUIT C This circuit protects the power transistors in case of overload, the speakersin caseof power amplifier malfunction, and also performs a muting function when the power supply is turned ON or OFF. The protection circuit is composed of three sections (Fis. 7). '
Power amplifier + Vcc
The collector current of Qu then flows through the relay coil, operating the relay to turn on the power amplifier output circuit. The reversebias of eu base from D6 & Rrg disappearswhen the power supply is set from ON to OFF. Q6 remains ON however, due to the residual power supply voltage. Ca very rapidly discharges, Q, base potential drops and Qr & Qs turn OFF. The relay releases and the power amplifier output circuit turns OFF.
Note: Q, is normally OFF due to base bias and does not participate in the muting operation.

Fig. Schematic 8. diagram relay of driver circuit Operation by Detector Circuit Command Command from the detector circuits pass through one of D., Do or D5 and are applied in the form of a current flow. Q, is normally reverse biased through R,o, but when a large current flows through on of these diodes, Qs base potential declines according to the voltage drop at R,a. Q5 then turns ON, Q6 base potential rises and Q6 turns ON. C4 rapidly dischargesand Q, base potential drops, turning Q, & Q, OFF. The relay releases and the power amplifier output circuit becomescut off.
1. RelayDriverCircuit (Fig. 8) The relay which connects the output circuits is driven by this circuit. It also performs a muting function to prevent unpleasant noise during ONOFF operation of the power supply as well as opening the output circuit on command from the detector circuits. Muting Operation When the power supply is turned ON, Qu base is reverse biasedthrough Du and R1e,turning Qu OFF. base potential rises as Ca chargesthrough Rr, & Qr R23,&nd Qr & Q* turn ON several seconds later.

2. OverloadDetector Circuit Shorting of the power amplifier load or a load impedance below the specified value causes a command to be sent to the relay drive circuit. This is illustrated in Fig. 9.
Q, and Qa compose a differential amplifier. When the same input is applied to both input terminals (Q. and Qo bases),no output is present. However, if there is a difference between the terminal inputs, the difference is amplified and becomesthe output between the two collectors. During normal operation, an AC signal only is present at the junction point. As C2 reactanceis sufficiently low, the same signal is applied to Q. and Qa bases,resulting in an absenceof output at the collector sides. When a DC potential is produced at the junction point, it becomes the input of Q, only. If the voltage is negative, Q, collector current declines. and at Qa the collector current increases and the potential drops, causing current to flow through
Do.
If the DC voltage is positive, Q, collector current increasesand the potential drops, while at Qa the and the potential rises. collector current decreases Current therefore flows through Ds.
Fig.9. Basic circuitry for overload detector
With the output stage in class B operation, when Qa is operating in the positive half cycle, Qb becomes cut off and the signal current flows as indicated by the solid arrows in Fig. 9. Point D potential at this time is the point A potential divided by Rt and R3. Also, point C potential is the point A potential divided by RE1 and RL (load). Point D is connected .to Qr base and point C to Qr emitter through R2 and REz. When RL is extremely small, the point C potential becomes considerably lower than point D. This potential difference forward biases Qt. Qt tums ON and current flows in D.. Qb operates in the negative half cycle and ea becomes cut off. The signal flows is indicated by the broken line arrows in the center of Fig. g. Qr is biased by the potential difference between point C and point E. If RL is extremely small, the point C potential becomes considerably higher than that of point E. Q, turns ON and current flows in D.. If large current flows in Qa and Qb, Q, becomes ON due to the RE1 and RE2 voltage drops, and current flows in Dr. C, prevents faulty operation due to external noise. 3; Center Point Potential Detector Circuit If a DC potential is produced at the junction point of the power amplifier, a command is sent to the relay drive circuit. Fig. 10 shows this operating principle.
