1. When you have a choice a balanced connection will offer slightly higher sound quality than an unbalanced connection The Ayre K 5x offers two pairs of balanced inputs and two pairs of unbalanced inputs Balanced connections are made via three pin XLR connectors while unbalanced connections are made via RCA connectors The input connectors on the rear panel are labeled to match the imput selector buttons The FET switches used in the input selector circuitry offer transparent noise free switching 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 In this modern era of diverse source components it has become impractical to pre label the inputs with the actual name of the source Instead the K 5x has simple icons that allow you to easily remember the selector button associated with each source component Tape Outputs If a recorder is not installed in your system the Moon input performs exactly like the other unbalanced inputs By connecting the Tape Out jacks on the rear of the K 5x to a recorder with analog inputs recordings may be made directly from the other source components connected to your preamplifier The tape outputs are switche2. connector labels on the control rear panel Star Planet Comet Moon are used to denote the inputs When the unit is first connected to an AC power source the Star input is selected by default The input selector utilizes sophisticated FET switches Both the signal and ground connections to each source component are switched so that any un selected components are completely disconnected from the system This avoids any problems with hat undesired ground loops Mute Muting and un muting may The mute button provides an easy way to also be performed with the temporarily turn the volume of the K 5x to zero remote control The current volume control setting is retained in memory and appears on the display Tape Output The Tape Output function When the Tape Output button is pressed the does not operate on the Moon indicator will light up and the signal from the imput This avoids the currently selected source component will be routed undesired possibility of to the Tape Out connectors This allows a creating a feedback loop recording to be made Turn the Tape Output off unless a recording is being made This will completely disconnect the recorder from the K 5x including the ground connection avoiding the possibility of undesired ground loops Display The display function is only The display of the K 5x may be turned off via the available from the remote remote control

10. t the heart of the Ayre K 5x s control system is a sophisticated microprocessor This microprocessor is normally asleep and all digital systems are turned off including the master clock When the microprocessor receives a command either from the front panel or the remote control it wakes up to execute the command and then immediately returns to sleep mode This system ensures noise free reproduction of music signals Volume Control The volume level is changed with the front panel knob The remote control may also be used to change the volume The Ayre K 5x s exclusive volume control yields superlative sonic performance Field Effect Transistor FET switches combine with discrete metal film resistors to create a volume control with crystal clear transparency and no moving parts along with digital accuracy and repeatability 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 Ayre EE low setting After that the current volume setting is retained in memory and will remain constant when changing inputs Input Source Selection The source component may also The input selector buttons are located below the be selected with the remote display Icons that match the
