Welcome to Ayre Your Ayre K-5xeMP offers a significant advance in the musical performance of high-fidelity equipment. The warmth and immediacy of a live performance are apparent from the first listening. The combination of superb resolution and a natural, relaxed quality will draw you into the music, time and time again. This level of performance has been implemented using the highest level of workmanship and materials.
Connections and Installation The Ayre K-5xeMP preamplifier is easy to connect and use. The following guidelines will ensure that the installation goes smoothly. Location The infrared beam of the remote transmitter will also travel through glass. A good location for your preamplifier is in an open-backed cabinet or on a shelf. The receiver for the infrared remote control is mounted behind the display lens on the front panel. A direct line of sight from the listening position will ensure the maximum range.
with no moving parts. Please be aware that they can be overloaded if the output voltage from the source component is too high. Do not use a source component that has an output level greater than 4 V rms unbalanced, or 8 V rms balanced. Using a source component with too great an output level will cause distortion. The input connectors on the rear panel are labeled to match the input selector buttons.
A y r e S.N. K-5 Stereo Preamplifier Boulder, Colorado USA Outputs B1 Right Channel B2 S1 S2 Left Channel Tape Out Volts 50/60 Hertz 10 W Max Tape Out S2 B2 B1 Outputs S1 Main Outputs The balanced outputs use XLR connectors, while the unbalanced outputs use RCA connectors. The Ayre K-5xeMP offers one pair of balanced outputs and one pair of unbalanced outputs. Both pairs of outputs may be used simultaneously.
Controls and Operation The Ayre K-5xeMP preamplifier may be controlled using either the front panel buttons or the included remote control handset. Basic functions are available at both locations, while additional functions are available only at the remote control handset. Remote Control The supplied remote control handset can operate both the K-5xeMP preamplifier as well as an Ayre CD player.
Basic Functions The following functions are accessible via both the front panel buttons and the remote control handset. Volume Control The volume control comprises 66 individual levels, each with a step size of 1.0 dB allowing for precise selection of the desired volume setting. When the unit is first connected to an AC power source, the volume level defaults to “11”, a relatively low setting. After that, the current volume setting is retained in memory, and will remain constant when changing inputs.
Input Source Selection The input selector buttons are located below the display. Alpha-numeric labels that match the connector labels on the rear panel (B1, B2, S1, S2) are used to denote the inputs. When the unit is first connected to an AC power source, the “B1” input is selected by default. Tape Output The “Tape Output” function does not operate on the “S2” input. This avoids the undesired possibility of creating a feedback loop.
display is off. When commands are received, either from the front-panel buttons or the remote control, the display will be activated for a few seconds to confirm the command, and then turn off automatically. Pressing the “Display” button on the remote control again will turn the display on. Processor Pass-Through When using the Ayre K-5xeMP in a surround-sound system for home theater, it is desirable to use the “Processor Pass-Through” mode.
the K-5xeMP can accept either balanced or unbalanced signals. To activate the “Processor Pass-Through” mode for that input, remove the AC power from the K-5xeMP for at least 10 seconds. Then, while pressing the input selector button corresponding to the chosen surround-sound processor input, re-connect the AC power. The chosen input is now programmed for “Processor Pass-Through” operation, disabling the now redundant volume control of the K-5xeMP.
