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 PRe2 control preamplifier fulfills all of these functions in a highly optimized design
providing remarkable signal fidelity. The powerful menu driven customizable control
interface can be optimized to provide an intuitive and easy to use means for controlling
your system, this is a user interface that emphasizes you, the user. The sophisticated LCD
display system remote control can be set to control a full system.
The PRe2 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 the most sophisticated audio system.
Design Features:
- Ultra-wideband, low distortion true balanced output buffer stage with selected audio
grade resistors
