There is no substitute for experience. Boulder’s proud history includes some of the finest preamplifiers ever made: the 2110, 2010, 1012 and 1010. Each has earned multiple awards, praise and accolades and are examples of the very best available. You can now add the 810 Preamplifier to that list.
Boulder's precise stepped volume control, descended from the 2010 Preamplifier
Supervising microprocessor oversees all functions and communicates with other Boulders
12V trigger connection to control power-up of remote amplifiers
Two pairs of main outputs for use in bi-amped systems and a third set of fixed-level outputs for secondary systems or recorders
Surface mount circuit board layout minimizes connection resistance and inductance and enables smaller board design
IR remote connection allows use with external control systems and maintains Boulder Link control with Boulder amplifiers
Fully-regulated power supply with additional power line noise filter
Two toroidal transformers, one for analog and one for logic, to prevent the controls from having any effect on sound quality
Left and right audio channels are each encased in steel boxes to improve isolation
