Page 6: Welcome To The Classé Family
Serial #: _______________________________________________________ a word about installation Every effort has been made to make the Classé CP-700 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 7: Unpacking And Placement
As with any preamplifier, it is best to place the CP-700 centrally within your system, since it is the hub to which all other components are connected. It... -
Page 8: Operating Voltage
If the AC mains voltage indicated on your preamplifier is incorrect, please contact your local, authorized Classé dealer or distributor. The CP-700 can easily be powered by a normal 15-ampere AC mains line. If other devices are also powered from the same AC line, their additional power consumption should be taken into account. -
Page 9: Warm Up/Break-In Period
warm up/break-in period Your new Classé 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 10: Special Design Features
In fact, in some ways it is even simpler to operate than a more conventional design might be. For example, if you are not using one or more of the inputs on your CP-700, 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 11: Extensive Listening Tests
This design approach ensures that the preamplifier itself sees only the pure, highly-regulated DC power it needs for handling the music signals, while the high-voltage AC mains is kept safely away from your music. In short, it creates an ideal environment in which the refined circuitry of the CP-700 can operate to its full potential in service of your musical enjoyment. -

Connect the analog outputs of any recording device (analog tape recorder, digital tape recorder, CD recorder, etc.) you may have to these single-ended RCA connectors. You may select to hear the output of your recording device by touching the tape button on the main operational screen of the CP-700. 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 16 Refer to the operating manuals of your balanced-output line-level sources to verify that the pin assignments of their output connectors correspond to the CP-700. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin.
- Page 17 If you are using another brand of power amplifier, please refer to the operating manual of your amplifier to verify that the pin assignments of its input connectors correspond to those of the CP-700. If not, have your dealer wire the cables so that the appropriate output pin connects to the equivalent input pin.
- Page 18 Classé CAN-Bus Control Ports These RJ-45 connectors are reserved for future control and communication applications using Classé Audio’s implementation of the Controller Area Network (CAN) Bus specification. IR Input and Output Your Classé preamplifier includes two 1/8th-inch mini mono-jacks in order to support the infrared (IR) remote controls that are ubiquitous today. Infrared commands exist (for example) for toggling the preamplifier between operate and standby, in addition to discrete command codes for either operate or standby.
- Page 19 Classé dealer can assist you in handling this problem if it should arise. DC Power Input The DC Power Input for the CP-700 is located near the middle of the rear panel. Connect the provided multi-pin “umbilical cord” between the outboard power supply and this connector to provide the preamplifier with the clean, pure DC power it needs to do its job.

Page 20: The Remote Control
The Remote Control Your new preamplifier comes with a versatile remote control which can control both the CP-700 itself and several aspects of the rest of a Classé-based system. The buttons are arranged in logical groups according to their functions. - Page 21 The F1/F2/F3/F4 keys are available for controlling aspects of the CP-700 not covered by the other buttons on the remote control. You are able to choose what the CP-700 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 22: The Menu System
In addition, the CP-700 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-700 to six (four single-ended and two balanced). -
Page 23: Main Menu System
This menu provides access to many installation-specific features that let you customize how the CP-700 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 collectively provide a great deal of control over your system setup. -
Page 24: Volume
volume Pressing the volume button takes you to the volume setup menu, which in turn has four submenus, all pertaining to how the volume of the system is managed. • rotary • max volume • startup volume • mute setup Each of these topics will be addressed in turn, below. - Page 25 Thus, if the CP-700 sees the knob moving relatively quickly, it uses coarse steps to effectively accelerate the action of the circuitry.

Page 26: Max Volume
This setting is interactive. You can set the value to something less than 100, and then adjust the volume to see whether it is appropriate. startup volume The startup volume screen allows you to define how the CP-700 handles its initial volume upon starting up. Your choices are: • last volume: this setting causes the CP-700 to behave as do basic... -
Page 27: Mute Setup
mute setup Pressing the mute setup button allows you to select one of three different muting functions: • Classic muting literally mutes the output when you engage the mute button; no sound will be heard. • Specific muting allows you to select a specific volume setting that you want used when you engage mute, regardless of what setting you might have been using the moment before. - Page 28 When an input is renamed ‘SSP’, it becomes a unity gain input. When such an input is selected, the volume control of the CP-700 is disabled, all outputs are driven at line level and the volume indication is removed from the main menu.

Page 30: Display Setup
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-700 controls, and stay on for only three seconds – just long enough for you to check on something. If you continue to use any of the controls (at least once every three seconds), the display will remain lit. -

(louder) or negative (quieter). People who have spent any time making recordings will recognize that this is similar to the notion of 0dB on a record level meter. In any event, the CP-700 offers both systems so that you may choose what makes the most sense to you personally. If you Enable Large Volume the volume level will be magnified on the touchscreen during volume adjustments. -

CAN-Bus is accessed by pressing the menu button on the face of the unit or remote, then the status button, followed by the more button. The touchscreen will then display the CAN-Bus devices screen, which lists connected Delta series components by model & serial number. Highlighting a unit on the CAN-Bus devices screen identifies it as the target unit. The front panel LEDs of the target unit will start flashing (unless you highlight the unit that you are using to access CAN-Bus). Once you have chosen the target unit press select. The target unit’s LEDs will stop flashing and the touch screen will list the CAN-Bus features available to it. Some CAN-Bus features are shared by all models, some are specific to individual models. CAN-Bus shared features The following CAN-Bus features are shared by all models. configuration Selecting configuration will present the CAN-Bus configuration screen allowing access to name, global brightness, and global standby features. -

Page 37: Amp Info
PlayLink is automatically active after a software update, and the PlayLink icon will only appear on the CAN-Bus configuration screen of a Delta series disc player. PlayLink can only select a single input per disc player. It is therefore not designed for users who regularly play both CDs and DVDs through different inputs from a single disc player. When PlayLink is active the disc player will default to the same input every time play is pressed, regardless of whether it is playing CD or DVD. -
Page 38: 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 39 Only one speaker seems to be playing. • Check the main balance control setting of the CP-700 by pressing the Menu button, followed by the balance button (or simply press Bal on the remote control). • Does the problem occur with all inputs? If so, check the interconnect cables between the preamp and the power amp. If no fault is found there, check the speaker wires for secure connections.
- Page 40 There is a mechanical hum coming from the unit. • This symptom suggests you have a lot of electrical noise on your AC mains line. Try connecting to another AC circuit (not merely a different plug, but a different circuit). • Check to see if you have any halogen lighting or dimmers on the same circuit as the preamplifier, as they can be the cause of hum in power supply transformers. There is a noticeable change in volume between one input and another, even though the volume was not adjusted.

Page 41: 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. Do not use excessive amounts of alcohol that might drip off the cloth and into the preamplifier. Caution! At no time should liquid cleaners be applied directly to the surface of the preamplifier, as direct application of liquids may result in damage to electronic components within the unit. -
