AUDIOPRO AP-3000 SERVICE MANUAL
M1012 THE INPUT BOARD
The input board processes the audio signal from the input jacks to the voltage amplifier board, (M1011).
Each channel consists of a balanced gain stage, defeatable bass boost filter, and a preemphasis filter network.
The balanced input, (XLR Jack) and unbalanced input (phone jack) are wired in parallel to the input of a balancedoperational amplifier, (U1). The gain of this stage is 1.6 (4dB) balanced and 1.6 (4dB) unbalanced. Resistors R1, R5along with capacitors C1 and C2 form a radio interference elimination filter.
Switch S1 selects a flat or bass boosted frequency response. The bass boost filter provides a 20Hz high pass, high Qfilter response with a +4dB peak at 55Hz. The filter consists of a tee network on the input of U1A along with R9, R10,R11, C5 and C6. The gain is 1 (0dB) in the passband, (above 100Hz).
Operational amplifier U3B is a high pass shelving filter with a +2dB shelf above 20KHz. This filter provides the pre-emphasis required to obtain a flat fr equency response (to 20KHz) on the power amplifier output at full power.
M1011 "VOLTAGE AMPLIFIERS AND SYSTEM CONTROL"
This board contains: Voltage amplifiers to drive the current amplifiers on the M1002 boards. The front panel volume control circuitry. The EMS control system with its associated circuits: Pre clipping and line current sensing heater circuits.
Clip and activity LED's. Driver circuitry for the amplifier disable relay (used during amplifier turn on, turn off,thermal shutdown and current limiting).
Circuit Explanation:
Refer to the schematic of M1011 as the sections of the circuit are explained.
The audio signal enters the board from M1012 through connector MS4. The two channels are marked "L" and "R" forleft and right. The signals are to be considered as differential sources and therefore are marked as L+, L-,R+ and R-.Since the left channel has the same topology as the right channel we will only look at the left channel.
The signal ("L+") at the terminal block (MS4) passes through the front panel level control (P1) and the desired levelenters the inverting input of U1.
Op amp U1 is an inverting amplifier with a set gain of 2.40 (7.6dB). Built around U1 is a dual purpose circuit controlledby a voltage divider consisting of R15, R16, R17, R18, R19, R20 and R21. The voltage divider sets two referencelevels, (HDRM & CLP). Reference voltage levels vary with the voltage levels on the +/-100VDC supply rails. As theamplifier?s output is loaded, the supply rails voltage decreases and so do the reference levels.
Transistors Q1, Q3 the surrounding resistors provide a pre-clipping function that tr acks the supply rails through theHDRM voltage reference and clips the audio signal at approximately 11.2V pk. The clip LED indicator circuit isconnected through D1 and D2 to the output of U1, The bases of Q2 and Q4 are connected to the CLP referencevoltage, and when the peak output voltage of U1 ( +/-Vp) is enough to forward bias the transister junctions, Q2 or Q4will trigger the clip led circuit (Q5), and eliminate the clip LED.

Identifying Defective Boards in the AP-3000 & AP-3400
Please note: All boards used in the AP-3400 are designated with an A' suffix (e.g. M1002A) anduse bright red solder mask
STEP 1: VISUAL INSPECTION OF FRONT PANEL AND FANa) Check to see whether the green power LED is lit. If not, the amplifier has a power supply (M1013board), transformer, A.C. switch or line cord problem.
b) If the red protect LED stays on or samples off and on, this usually indicates a problem with one or both
of the M1002current amplifier modules and possibly damage to the M1012voltage amplifier board.Note: Any of the Molex cables from the M1011circuit board to the M1012input board as well as theM1002 current amplifiers can cause the protect LED to stay on or sample on and off. Check formisaligned pin connections or see if the ribbon cables have been cut or pinched through their insulation.
c) The fan running at full speed on power up usually indicates a problem with the fan circuitry on theM1013board, but it can also be caused by M1011circuit problems. Erratic fan behaviour can be causedby damaged thermistors located under the M1002heat sinks.
d) No output on either or both channels can be caused by intermittent push switches at the input.
STEP 2: VISUAL INSPECTION OF INTERNAL CHASSISa) After removing the lid, look for any signs of smoke, charring or burnt components. If the M1002boards have such damage, the M1011, M1012and M1013boards may also be damaged even if there isno similar charring on their components. At the least, there will be some damage to the M1011voltageamp board in the form of blown ICs, or possibly open or shorted diodes, LEDs, resistors, transistors orcapacitors. Exploded electrolytic capacitors indicate you have major repairs to the M1002, M1011andM1013boards.
STEP 3: POWER UP PROCEDURE WITHOUT M1002 BOARDSIt is extremely important that you never power up an AP-3000 or AP-3400 without following theprocedure located on the M1011schematic highlighted within the box drawn in dashed lines. Failure to doso will possibly result in damaging a good board. This procedure should only be done on a no loadscoped output to insure the rest of the circuit boards are working before installing new or repaired M1011modules. The output of a fully operational M1011will give a 70V peak to peak sinusoidal (undistorted)wave form when a patch plug is attached at Pin #1. If the wave form is distorted or non- existent, or thereis DC offset, do not attempt to connect any M1002module to the M1011or you will immediately destroythe new or repaired M1002and will also cause more damage to the rest of the amplifier.Note: M1002?spower supply wires (red, yellow, white, blue and black) must be removed as well as theinput Molex ribbon to the M1002when attempting to power up an M1011.
STEP 4: DISMANTLING AND REASSEMBLY PRECAUTIONSa) When removing power supply wires or resoldering wires to eyelets on the M1011board, double checkthat there are no solder bridges or icicles bridging traces or other eyelets. Failure to do so will result in thedestruction of newly installed boards as well as other boards in the unit. Also make sure wire color codesare correctly oriented in their proper eyelets, and be careful that ribbon cables don?t get pinched or cutunder the M1011boards as this will result in shut down into the protect mode or even destruction of moreboards.b) When reinstalling M1002boards, make sure the output wires, i.e. the red and yellow signal and blackground wires, are not reversed. If either channels or both are reversed, the amp will stay in protect modewith the red LED staying on or sampling on and off.
