Ayre Acoustics K-1x Car Amplifier User Manual


 
Unlike other products that use conventional volume
controls (potentiometers), the Ayre K-1x uses a mil-spec,
precision stepped attenuator with solid-silver contacts to
provide the ultimate in sound quality. This volume control
features 46 distinct positions, offering precise and repeatable
settings.
It is normal to listen with the
volume knob advanced farther
than you may be used to with
other equipment.
The volume control offers 1.0 dB steps over most of its
range, allowing you to exactly select the desired listening
level. To maximize its capabilities, it has been designed so
that the volume knob will be between 1 o’clock and 3
o’clock for a loud playback level in most systems.
When a surround-sound processor is used, it is sometimes
useful to know the unity-gain volume setting. Since the
gain of the Ayre K-1x line-stage is 16 dB when driving a
power amplifier with balanced inputs, unity gain occurs
when the volume control is 10 steps below the maximum
setting (see illustration).
Since the tape record selector
(“Record”) is controlled
separately from the main
input selector (“Listen”), it is
possible to listen to one source
while recording from another.
The tape record selector (“Record”) controls which source
component is connected to the tape output jacks. It is
recommended that the tape record selector be switched to
the “Off” position except when making a recording. This
will isolate the tape deck’s circuitry from the preamplifier,
providing the highest level of sound quality when listening.
Remote Control
Please note that the supplied
batteries (2 x AAA) must be
installed in the remote control
unit prior to use.
The optional remote control for the Ayre K-1x has four
buttons. The top two buttons on the right side control the
volume level, while the bottom button on the right side
toggles the preamplifier’s mute control. The single button
on the left side of the hand-held transmitter will operate an
Ayre V-1x power amplifier.
