Boulder – 2110 preamplifier
The 2110 is Boulder’s highest performing, continuously-produced preamplifier.
Inside there is a fully-balanced volume attenuator and electronics boasting precision surface-mount technology.
Outside, there is a modern and luxurious look highlighted by a wrap-around mirror-glass display window
and hand-polished controls. Six inputs, three outputs and extensive programming features make this Boulder
the heart of any world-class audio system.
Balanced version of Boulder’s analog discrete step volume control is programmable for 0.1, 0.5, and 1.0 dB steps.
Four separate chassis: left audio, right audio, user interface, and power supply to isolate the analog channels from supply,
control, and display noise.
Large, easy-to-read, dot matrix LED display.
Six pairs of programmable, differentially-balanced inputs.
Three pairs of balanced outputs for bi- and tri-amplified systems or powered subwoofers.
Cut mirror glass display window to match the hand-polished stainless steel buttons and volume control.
Separate power supply chassis houses three independent power supplies: analog left, analog right and control functions.
Every input can be custom named and configured for user preferences.
Auxiliary outputs are programmable to feed secondary systems or recording devices.
Uses 12 high-current output 993S gain stages, a discrete and modern version of the 990 gain stage used in broadcast
and recording studios world-wide.
Each input can be configured for Theater Mode when used in home cinema installations.
Boulder Link and 12V trigger for use with external control systems.
