Summary of Contents for Crown XLS1000

  • Page 1: Service Manual

    XLS1000 – 2500 Service Manual 142195-1 4/10...
  • Page 2 XLS3 Tech Support.doc XLS-3 MENU: The XLS main menu structure communicates functionality of the amplifier in terms of its input routing (MODE), filter selection (FILTER), and frequency of the filter (FREQ)…when available. MODE: Amplifier audio routing. STEREO: Channel 1 input to Channel 1 output, Channel 2 input to Channel 2 output.

  • Page 3: Diagnostic Menu

    XOVER: When XOVER is selected, the MODE choice is automatically changed to INPUT Y. Channel 1 is fed to both channels’ processing with Channel 1 being Lowpass and Channel 2 being Highpass. The crossover frequency is determined by the FREQ choice. CLIP COMPRESSOR: Allows the clip compressor for each channel to be either turned on or off.
  • Page 4 A set of diagnostic menus can be accessed at anytime by pushing all three menu buttons at the same time. The amplifier continues to pass audio, but the diagnostic menus are displayed until the MODE/MENU button is pushed and normal amplifier functionality returns.

  • Page 5: Error Codes

    ERROR CODES: The amplifier’s processor runs through a series of Power On Self Tests (POST) when the amplifier is first powered up. If the processor encounters an error, it will communicate the error via the front panel Thermal LED’s. These error codes are unique and based upon a Major and Minor element. The Major element is determined by which portion of the amplifier failed POST, while the Minor portion is which part of the Major element failed.
  • Page 6 tested. MFGTEST GPIO Comm Fail APM is unable to communicate with the MFG Test fixture’s I2C GPIO registers. MFGTEST ADC Comm Fail APM is unable to communicate with the MFG Test fixture’s I2C ADC registers. CHASSIS LEVEL SELF-TEST: This test is used to ensure the functionality of the LCD, Buttons, and Fan once the amplifier is assembled.

  • Page 8: Analog Inputs

    APM SECTION THEORY OF OPERATION ANALOG INPUTS: The input to the APM can accept 1.4Vrms input and drive the resultant APM output to a level that drives the amplifier to full rated power into 8 . The differential analog inputs come from J700 which connects to the MAIN board of the amplifier. The input XLR, ¼”, and RCA connectors tie directly to this point on the MAIN board.
  • Page 9 XLS1500 – 2500, R613-614, R617, R620 form the voltage divider and bias network into the Cirrus codec (CH2±_AD). As you can see, the major difference between the XLS1000 and XLS1500 – 2500 APM’s resides in the use of an external Cirrus Codec (U702) for the larger amplifiers.

  • Page 10: Analog Outputs

    The output of the APM is driven by a differential gain stage (U701-C,D) that receives its input from the DAC. In the case of the XLS1000, the DAC resides within the TI DSP (CH2±_DSP_DA), while in the case of the XLS1500 – 2500, the DAC is part of the Cirrus codec (CH2±_DA).

  • Page 11: Serial Communications

    The DSP runs at 48KHz sampling rate and also requires that the external codec also samples at 48KHz. The DSP utilizes I2S digital audio to get audio to/from the external codec (DSP_SDIN, DSP_SDOUT). The timing diagram below shows the relationship between serial clock (SCLK), channel clock (LRCK), and digital audio (SDIN, SDOUT).

  • Page 12: Bridge Mode

    Thermal Limiter Compressor (TLC): There are thermistors that monitor each of the amplifier channel’s heatsinks as well as one that monitors the heatsink for the secondary diodes (±Vcc) of the power supply. The TLC adjusts the gain at a rate of 1.25dB/°C at temperatures greater than 75°C.
  • Page 13 As can be seen by the DSP signal flow, when the amplifier is placed in Bridge mode, CH1 signal is taken post-crossover, inverted, and sent to CH2 output. This ensures that the gains are matched and that the same signal is on both outputs (CH2 = -CH1).

  • Page 15: Microprocessor Control

    MICROPROCESSOR CONTROL: Boot & POST: The microprocessor boots from its internal FLASH and does a variety of Power On Self-Tests (POST). See the Error Codes section of the manual for a description of all of the error codes and their meanings. RUBY Interface: Part of the processor’s POST involves interface with Ruby and ensuring that it is up and working.
  • Page 16 Front Panel LED’s & Switches: The processor monitors the (3) front panel control switches and provides the necessary interface to the display and amplifier. In addition, the processor monitors the thermal sensors from Ruby and provides thermal LED lights during over temperature.

Balanced to unbalanced input stage. The channel one balanced audio enters the amplifier at one of the back panel connectors J101, J102 or J3.

  • Page 28: The Output Stage

    The High Frequency Feedback comes directly from the switching node at the junction of the output MOSFETs and the input to the output filter at L101. This signal has the full switching signal on it and therefore must be filtered. R139/140 and C176 provide the first filtering to attenuate the VHF spectrum.
  • Page 29 U102 has programmable dead-time which can be changed by the APM through a programming current drive into Q107-108. U102 provides current limit protection for the MOSFETs. R153-154 set the negative current limit and R158-159 set the positive current limit. U102 provides under-voltage protection for the MOSFETs to protect against low gate drive voltage.
  • Page 30 R22/23/24 provides a way for the APM to know what model of amplifier it is connected to. See the chart below. XLS 2000/2500 Amplifier Theory of operation. The XLS2000 and XLS2500 are very similar to the XLS1000/1500 and so only the differences will be discussed here. XLS 2000/2500 Output Stage.

    The power supplies of the XLS series of amplifiers are efficient and light weight, but yet extremely robust switchmode designs. The topology of the main supply employed is a half-bridge series resonant converter. The use of this topology allows for soft switching of the main semiconductors Q903 and Q906 reducing dissipation at idle and throughout the operating power range.
  • Page 33 wave-secondary rectifier, and control circuitry. In addition two components are added to form a resonant tank which significantly increases the overall efficiency of the converter. The IGBTs, Q903 and Q906, switch at approximately 40% duty cycle each at a frequency of 96kHz.

  • Page 34: Low-Voltage Power Supply

    C947 & R910 set the free running frequency of the internal oscillator of U902, until synchronization to the master clock is achieved. The deadtime between when one IGBT turns off and the other one turns on is set by R911. During startup C917 forms a time constant with R911 that determines the rate at which the duty cycle increases from 0% (off) at startup to the final duty cycle of approximately 40% on each switch when it is running.
  • Page 35 kHz, one quarter the amplifier switching frequency. The synchronization is necessary to prevent beat tones from forming in the amplifier output stage. A 192 kHz balanced square wave signal is generated on the APM and is routed to the main board via J700B pins #24 & #25. Q909 resets the timing cap (C944) on the +5V control IC (U905) when the “CLKP192K”...

    APPENDIX A: VIC’s Report of XLS-3 by Victor Marquis NEW XLS series Overview Page 1 of 6 Introduction to the new XLS family of amplifiers. Consisting of the XLS1000 XLS1500 XLS2000 XLS2500 Very efficient very powerful and very lightweight. Good specs and easy to use.
  • Page 77 NEW XLS series Overview Page 2 of 6 XLS2500 this is a state of the art amplifier with Efficiency and weight as its major advantages. The input stage has simple easy to manipulate crossovers that can be setup as ch1 low pass and ch2 high pass or both channels low-pass and or both channels high- pass.
  • Page 78 NEW XLS series Overview Page 3 of 6 Additionally you can turn down the high pass channel by adjusting the input Potentiometer and then you can drive the Low frequencies higher and not overwhelm the mid’s and highs. So you can have full power delivered to the woofers and 4- 6 to 12dB less delivered to the mid’s and highs.
  • Page 79 NEW XLS series Overview Page 4 of 6 The amplifiers efficiency is the highest efficiency I have ever tested. Especially at 2 ohms where efficiencies can hover between 25% for conventional Class AB output stage to 35% to 45% with a tracking supply depending on the topology of the tracking supply. BCA amps average 60% at 1/3 power 2 ohms.
  • Page 80 NEW XLS series Overview Page 5 of 6 The amplifiers output stage can recycle reactive load energies that are normally wasted as heat in the amplifiers output stage. You can see the Reactive power out is 346W or VA and the power consumed by the amp is only 114W. That is because the amplifier is recycling the power.
  • Page 81 NEW XLS series Overview Page 6 of 6 This was running music at max power into 2 ohms both channels driven for 1 hr continuous. All temperatures were well in control and stabilized. The thermals are very good considering the extreme levels used during this test. Most customers will never run this much power for this sustained time.
