POWER 120 VAC , 50 - 60 Hz, 30 0 0 W Max
Ultra-high current power connector
Easy to connect, rugged, high current, speaker terminals
require no tools
Advanced protection
circuits provide trouble-
free operation
Supervising
microprocessor oversees
all functions and
communicates with other
Boulders
48 filter capacitors
(beneath the PCA)
assure a low impedance,
distributed power supply
Boulderlink allows
multiple 1050s to be
sequentially turned on,
and transmit their status
to the display on a
Boulder preamplifier
Dampened heatsinks
are an integral part of
Boulders machined, quiet
chassis
Multiple gain stages
provide most of the gain
in the first stage thus
maximizing bandwidth
Encapsulated and
magnetically shielded
power transformers for
quietest performance
56 Output transistors
provide stable operation
with any loudspeaker
