  • Page 3: Product Description

    Product Description The Ultima Pre is the ultimate high-end reference product and is the perfect partner to the Ultima mono block amplifiers. In the same double height format to match it has all the features of the already advanced CPA5000 but now includes three pairs of outputs, true dual mono construction with separate power supplies for each channel, and separate left and right frequency EQ adjust.

  • Page 4: Setting Up

    Ventilation Your Ultima pre should have at least 5cm of clear space all around it to ensure a free flow of air at all times. We do not recommend that you place Ultima Pre directly on a carpet. AC lead and plug All Chord equipment comes supplied with the correct power lead and plug.

  • Page 5: Safety Warnings

    Safety Warnings It is important that your Ultima Pre is earthed at all times via its own mains lead. Failure to do this may be hazardous. The power supply components within the Ultima Pre are designed to operate at lethal voltages and energy levels.

  • Page 6: Ac Power Connection

    AC Power connection The AC power connector of Ultima Pre is at the back of the unit. Plug the female end (socket) of the power cord into the power connector of the preamplifier, and the male end(plug) of the power cord into AC wall socket or AC extension socket.

  • Page 7: Connecting Your Equipment

    Chord amplifiers are supplied with and designed to be connected using balanced inputs. The interconnecting cables you use will depend on the available input and output sockets on your other equipment. We have installed unbalanced inputs on all Chord equipment, thus enabling you to mix Chord Electronics and other manufacturer’s equipment.

  • Page 8: Input Connections

    It does not matter which input you choose just select the same type of connection that your source has. Note: Moving coil turntables without an internal amplifier will require an external phono stage amplifier such as the Chord Symphonic before connecting to the Ultima Pre.

  • Page 9: Output Connections

    Output Connections You need to connect the outputs on the back of the Ultima Pre to a power amplifier in order to drive your loudspeakers. There are three pairs of balanced XLR outputs and three pairs of RCA phono outputs, each of which will drive a 68 ohm load.

  • Page 10: Recording

    Recording You can record an input from another audio source or two sources at the same time. If you’ve been using a tape recorder as an input source, it will already be connected to the 7 or 8 input sockets. If you haven’t, first connect the tape’s output to the 7 or 8 input sockets.
  • Page 11 EQ Frequency Controls On the front panel are the EQ frequency controls. There are four controls, two for each channel, one for high frequency and one for low frequency. Using these you can adjust the low and high frequency response for the left or the right channel. The settings affect all the inputs and outputs but not the AV bypass or tape output loop.

  • Page 12: Headphones

    AV processor reaches the power amplifier exactly as if it were connected directly. This has the advantage of allowing the Ultima Pre to remain in an AV system to give the best possible stereo two channel playback whilst still being able to switch to AV bypass mode to allow the processor to playback multichannel film content.
