9、oFans.CN 收音机爱 好者资料库 DELUXE 112 PLUS THEORY OF OPERATION Input 1 is a high sensitivity input. Input 2 is a low sensitivity input. Inputs 1 and 2 contain series switches that connect to +16Vdc via a third series switch located within the Power Amp in jack (J5). From the input jacks, this series circui

10、t terminates at the gate of JFET Q7. Q7 is part of a muting /turn on delay circuit for the input of the power amp. Therefore the input signal to the power amp will remain muted until a plug is inserted into either Input 1,2 or the Power Amp in jack. The first stage (U2A) sets up the initial response

11、 of the amplifier. It provides a second order high pass filter with a 3dB down point at 60Hz, and a gain of about 3.8. The output of U2A splits to feed the clean and overdrive channel. For the clean channel, the signal feeds the Treble, Bass and Mid controls that provide boost and cut respectively.

12、The signal then flows to U7A. U7A is a buffer for the adjustable high pass filter made up by C59, C60, R108 and R109. The inverted signal at U5A is sensed through R109 and fed back to the junction of C59 and C60. As the Volume control is turned up, the feedback from R109 provides 6dB of attenuation

13、at 30Hz. This prevents the speaker from flapping at very low frequencies. U2B is an Auto-pad circuit. It provides excellent headroom and low noise. The signal split from U1A feeds the overdrive channel through a special tone shaping circuit located just prior to U2A. This circuit is a third order ba

14、ndpass filter with a peak boost at 2.2kHz. It provides the optimum frequency response for the following distortion circuit. U2A provides the variable gain adjustment that drives the distortion circuit. It also acts as a bandpass filter with 3dB down points at 90Hz and 4kHz. U2B is the distortion cir

15、cuit. LD1 and LD2 provide diode distortion. The Contour control adjusts the overall tone quality of the overdrive channel by emphasizing or notching the mid range frequencies. In the fully CCW position the response is fairly flat up to about 2kHz, where a gentle roll-off occurs. In the fully CW posi

16、tion, the circuit provides a 20db notch at about 1kHz. The signal then feeds the overdrive volume control and the treble and bass controls. The signal from the Clean and Drive channels sum at U5A via JFETs Q4 and Q5. The output from U5A feeds the reverb drive circuit (U6A) and summing amp U5B. U6B i

17、s the reverb sensing circuit. The output of U6B drives the Reverb volume control and then sums with the dry signal at U5B. The output of U5B drives the preamp out jack, is normalled through the power amp in jack, and feeds the power amp input. CHANNEL SWITCHING The AC voltage from the power transfor

18、mer secondary is tapped off through resistor R82, and presented to the footswitch jack (Approx 20 V RMS). By rectifying the positive or negative side of the waveform, we create a DC control voltage that is sensed by comparators U4A and U4B. Diodes CR20 and CR21 set up the reference voltages for the

19、comparators. Therefore the control voltage must toggle between +15Vdc and 15Vdc. The comparator output controls the JFETs and the indicator LEDs. Without the footswitch connected to the footswitch jack, CR15 rectifies the negative half of the waveform. U4B senses the DC control voltage, and provides

20、 15Vdc to the gate of Q6, allowing the reverb output to function. POWER AMP U1 is a high voltage op-amp that provides voltage gain for the power amplifier. CR3 and CR4 act as differential protection diodes that prevent the positive and negative inputs of U1 from becoming more than 0.6 volts apart. B

21、ootstrap Capacitors C37 and C38 sense the output through R69. This provides more voltage swing for the opamp with respect to ground. Diodes CR5-CR8 (BYV26D) make up the Fixed Bias circuit for the output transistors. The Bias Diodes mount through a hole in the transistor heatsink. This ensures the Di

22、odes will properly track the temperature of the output transistors. These Diodes were selected because they exhibit a 2mV decrease in Knee Voltage for every 1 degree (Celsius) increase in temperature. Pin 6 of U1 is at 0 Vdc. Therefore the Bias Diodes provide 2 voltage drops (+/- 1.2volts) to the Ba

23、se of Darlington Transistors Q1,Q2, Q10 and Q11. DELUXE 112 PLUS THEORY OF OPERATION (CONT) Diodes CR9-CR12 make up a voltage clamp protection circuit. Q8 and Q9 make up a current limiting protection circuit. If the output is shorted, the voltage at the emitters of Q10 and Q11 will increase. This vo

24、ltage is sensed through R100 and R107 and presented to the bases of Q10 and Q11. When Q10 and Q11 turn on, the drive current and bias to the output transistors is removed, which shuts down the output section of the amplifier. The output signal feeds through the Headphone jack circuit, before driving

25、 the speaker. With headphones connected to the headphone jack the speakers are muted.
