Specific features vary depending on model. 1.1 Introduction 1.3 Scope This manual contains complete service information on the Crown® MA-3600VZ power amplifier. It is designed to be used in conjunction with the Reference Manual; however, some important information is duplicated in this Service Manual in case the Reference Manual is not readily available.

MA-3600VZ Service Manual 130366-1 Rev. A 2 Specifications These specifications apply to 120 VAC units in stereo mode with 8 ohm loads and an input sensitivity of 26 dB unless otherwise specified. 120 VAC, 60 Hz Units: These units are equipped with transformers rated for 120 VAC, 60 Hz power. International Units: These units are equipped with transformers for either 100 VAC, 50/60 Hz, or 230 VAC, 50/60 Hz power. 2.1 Performance Frequency Response: ±0.1 dB from 20 Hz to 20 kHz at 1 watt.

130366-1 Rev. A MA-3600VZ Service Manual ence. In the unlikely event the output waveform differs from that of the input by 0.05% or more, they flash brightly to indicate distortion. As sensitive distortion indicators they provide proof of performance. Note: It is normal for the Channel 2 IOC indicator to remain on in Parallel-Mono mode. ODEP: Each channel has a multifunction LED (light emitting diode) indicator that shows the channel’s energy reserve status.

MA-3600VZ Service Manual 130366-1 Rev. A 3 Theory of Operation 3.1 Overview It should be noted that over time Crown makes improvements and changes to their products for various reasons. This manual is up to date as of the time of writing. For additional information regarding these amplifiers, refer to the applicable Technical Notes provided by Crown for this product. This section of the manual explains the general operation of a Macro-Tech 3600VZ power amplifier.
PAGE 12
130366-1 Rev. A MA-3600VZ Service Manual Also tied into the Voltage Translator inputs are ODEP limiting transistors and control/protection transistors. The ODEP transistors steal drive as dictated by the ODEP circuitry (discussed later). The control/protection transistors act as switches to totally shunt audio to ground during the turn-on delay, or during a DC/LF or Fault protective action. an AC coupling capacitor and input resistor.
PAGE 13
MA-3600VZ Service Manual 130366-1 Rev. A 3.5.1 High Side (HS) The High Side (HS) of the bridge operates much like a conventional bipolar push-pull output configuration. As the input drive voltage becomes more positive, the HS NPN conducts and delivers positive voltage to the load. Eventually the NPN devices reach full conduction and +Vcc is across the load. At this time the HS PNP is biased off.
PAGE 14
130366-1 Rev. A MA-3600VZ Service Manual and are biased AB+B in the same manner as the HS. 3.6 Output Device Emulation Protection (ODEP) When the amplifier output swings positive, the audio is fed to an op-amp stage where it is inverted. This inverted signal is delivered directly to the bases of the positive (NPN) and negative (PNP) LS predrivers. The negative drive forces the LS PNP devices on (NPN off). As the PNP devices conduct, Vce of the PNP Darlington drops.
PAGE 15
MA-3600VZ Service Manual 130366-1 Rev. A According to Ohm’s Law, the bigger the power supply, the more heat the power transistors must dissipate. Also, the lower the resistance of the power transistors, the more voltage you can deliver to the load. But at the same time that you lower the resistance of the transistors, you increase the current passing through them, and again increase the amount of heat they must dissipate. 3.7.

130366-1 Rev. A MA-3600VZ Service Manual • Higher than normal on-state drain to source voltage FETs at pin 5. R17 in series with R18 forms a voltage divider to pin 5 of U05. The reference is set by a voltage divider formed by R29, R20, and R22. • Gate drive present. When both of these conditions exist, a reasonable assumption can be made that the FETs are operating in an area that if sustained will cause damage to the FETs. These two conditions are detected by U05 pins 5 and 7.

MA-3600VZ Service Manual 130366-1 Rev. A 4 Maintenance 4.1 Cautions and Warnings DANGER: The outputs of this amplifier can produce LETHAL energy levels! Be very careful when making connections. Do not attempt to change output wiring until the amplifier has been off at least 10 seconds. WARNING: This unit is capable of producing high sound pressure levels. Continued exposure to high sound pressure levels can cause permanent hearing impairment or loss.

With level controls fully clockwise you should see full gain. As controls are rotated counterclockwise, observe similar gain reduction in each channel. When complete, return level controls to fully clockwise position. 4.3.10 Test 9: Current Limit Spec: Current Limit at 43 - 48 Amps Initial Conditions: Controls per standard.

130366-1 Rev. A MA-3600VZ Service Manual 4.3.18 Test 17: Turn On Transients Procedure Torture: Load each channel with the primary (red and black leads) of a PSU transformer (D 7040-5). Inject a 35 Hz sine wave for an output level of 89.5 Vrms, for 10 seconds. Procedure Short: Inject a 60 Hz sine wave with 30.0 VAC at the amplilfier output. After establishing signal, short the output for 10 seconds. Spec: No dangerous transients. Initial Conditions: Controls per standard.
