    You will find the warranty registration card at the end of the separate warranty policy booklet, enclosed. a word about installation Every effort has been made to make the Classé CP-500 simple and straightforward to install and use. Still, we have no way to evaluate many other variables such as the size and shape of your room, its acoustics, and the associated equipment you have chosen to use with your preamplifier.

  • Page 6: Unpacking And Placement

    As with any preamplifier, it is best to place the CP-500 centrally within your system, since it is the hub to which all other components are connected. It should also be located at a convenient height for both visibility and use, since you generally interact with your preamplifier more than any other component...

    It will take only a minute or so. Please complete the card now, before you forget. operating voltage The CP-500 preamplifier is set at the factory for 100V, 120V, 230V, or 240V AC mains operation, as appropriate for the country in which it is to be sold (230V only in European Union countries, in compliance with CE regulations).

  • Page 8: Warm Up/Break-In Period

    warm up/break-in period Your new Classé power preamplifier will deliver outstanding performance immediately. However, you should expect to hear it improve somewhat as it reaches its normal operating temperatures and its various components “break-in.” It has been our experience that the greatest changes occur within the first 300 hours, as the preamplifier reaches thermal equilibrium and the capacitors fully form.

  • Page 9: Special Design Features

    For example, if you are not using one or more of the inputs on your CP-500, you can delete the unnecessary buttons from the operational menu. Doing so prevents anyone from trying to select a non-existent source component, with the resulting confusion stemming from the lack of any sound.

  • Page 10: Extensive Listening Tests

    extensive listening tests Excellent measured performance is to be expected in world-class products, and Classé products deliver that performance. However, experience has shown that technical excellence alone is insufficient to guarantee subjectively musical results. For this reason, all Classé products are laboriously fine-tuned during the development process by carefully controlled listening tests.

You may select to hear the output of your recording device by touching the tape button on the main operational screen of the CP-500. Single-ended (RCA) inputs These RCA jacks accept right-channel and left-channel (single-ended) inputs from line-level source equipment such as tuners, CD players, and tape decks.

  • Page 19: The Remote Control

    The Remote Control Your new preamplifier comes with a versatile remote control which can control both the CP-500 itself and several aspects of the rest of a Classé-based system. � ������� The buttons are arranged in logical groups according to their functions.
  • Page 20 The F1/F2/F3/F4 keys are available for controlling aspects of the CP- 500 not covered by the other buttons on the remote control. You are able to choose what the CP-500 should do in response to receiving the infrared signal that a particular Fkey has been pressed. The list of possible functions is quite extensive, and is found in the menu system (see the next section in this manual, entitled The Menu System).

  • Page 21: The Menu System

    In addition, the CP-500 has a dedicated tape loop for use with sources that can both record and play back, bringing the total number of sources you can connect to the CP-500 to six (four single-ended and two balanced).

    This menu provides access to many installation-specific features that let you customize how the CP-500 works within the context of your particular system. system setup The first button on the control menu takes you to a series of submenus that...

  • Page 23: Rotary

    Thus, if the CP-500 sees the knob moving relatively quickly, it uses coarse steps to effectively accelerate the action of the circuitry.
  • Page 24 Of course, it is possible to bump into the knob by accident, which might result in its spinning very quickly indeed. Rather than increasing the volume uncontrollably under these conditions, the CP-500 actually slows everything down again as a safety measure against accidentally blowing your speakers. In fact, if you like you may establish a speed limit beyond which the knob will simply be ignored.

  • Page 25: Input

    • speed limit: establishes a maximum rotary speed, beyond which there will be no change in volume whatsoever; the knob’s input will be ignored completely until it is first stopped, and then rotated at a slower speed. • reset defaults: if after experimenting with various settings you decide you prefer it the way it operated as it came from the factory, pressing this button will restore the factory default settings.
  • Page 26 When an input is renamed ‘SSP’, it becomes a unity gain input. When such an input is selected, the volume control of the CP-500 is disabled, all outputs are driven at line level and the volume indication is removed from the main menu.

  • Page 27: Phono Gain

    Each of the CP-500’s trigger outputs may be programmed as to its “logic level,” which is to say, whether its voltage is low (essentially 0V), or high (approximately 12V) when the trigger is activated.

  • Page 28: Teach Ir

    The teach IR screen provides a scrolling list of all the available IR codes in the CP-500. By scrolling to the command you need to learn into your macro- capable remote, and then pressing the send IR code button, the CP-500 will send the appropriate command code out its front panel–where it can be learned...

  • Page 29: Brightness

    For example, if you reduce the timeout to its minimum setting, the backlighting will illuminate the display as soon as you interact with any of the CP-500 controls, and stay on for only three seconds – just long enough for you to check on something.

  • Page 30: Remote Fkeys

    Fkeys The remote control supplied with the CP-500 has four function keys (Fkeys) that allow you to have instant, easy access to specific system functions that might otherwise be buried in a menu somewhere. For example, if you use the balance control frequently, you may want to consider programming one of the Fkeys to take you straight to that screen.

  • Page 31: Status

    The status screen provides several items of information about the current operation status of the CP-500, as well as access to information on the software used in and the internal sensors of the CP-500. version info The version info button on the status screen takes you to the version information screen, which displays information on various pieces of software used by your CP-500.

  • Page 32: Troubleshooting

    Troubleshooting In general, you should refer any service problems to your Classé dealer. Before contacting your dealer, check to see if the problem is listed here. If it is, try the suggested solutions. If none of these solves the problem, contact your Classé dealer.
  • Page 33 Only one speaker seems to be playing. • Check the main balance control setting of the CP-500 by pressing the Menu button, followed by the balance button (or simply press Bal on the remote control).
  • Page 34 There is a hum coming out of the speakers. • If you are running single-ended interconnects, make sure they are not running alongside any AC power cords. • If you are running single-ended interconnects, make sure they are not too long. Long runs of single-ended interconnects have a natural tendency to pick up noise even if they are shielded.

  • Page 35: Care And Maintenance

    Care and Maintenance cleaning the cabinet To remove dust from the cabinet of your preamplifier, use a feather duster or a soft, lint-free cloth. To remove dirt and fingerprints, we recommend isopropyl alcohol and a soft cloth. Dampen the cloth with alcohol first and then lightly clean the surface of the preamplifier with the cloth.
