Ref
Pre3VB stereo line stage preamplifier with balanced input and
output. High performance VB power board and LNS1 external power
supply
The control preamplifier plays the central role in the audio system:
It
must switch among multiple sources.
Accept both balanced XLR and Single-ended RCA inputs.
Accurately control the volume or level of the audio signal.
Allow simple soft and hard muting of the signal
Provide remote control function.
Condition and buffer the balanced XLR outputs to optimally drive
the power amplifier.
It must provide these functions while maintaining all of the low-level
signal information, imposing minimum noise and bandwidth reduction
and low levels of linear and non- linear signal distortion, all
while providing a simple and intuitive control interface.
The
PRe3 control preamplifier fulfills all of these functions in a
highly optimized, compact design providing remarkable signal fidelity.
The unique, Single-Knob control interface insures an intuitive
and easy to use means for controlling your system, this is a user
interface that emphasizes you, the user. The compact dedicated
remote control is also easy to learn and use and adds soft and
hard mute functionality.
The
PRe3 signal path and power supply architecture provides remarkably
low levels of non-linear distortion, extremely low-noise levels,
wide bandwidth with a high degree of control accuracy and channel-channel
tracking to insure a seamless and utterly transparent means to
controlling your audio system.
