MARK II-B OPERATING MANUAL 1
Congratulations! You have purchased the finest musical instrument amplifier that modern technology and old world craftsmanship can produce. Nothing has been spared in terms of cost or care to make this unit the most versatile, most reliable, and best sounding amplifier available. The MESA/Boogie itself is more like a fine musical instrument than a piece of commercial gear, and as such it will continue to reward you richly as you gain more practiced in its use.
The Slave Level control and Slave Output jack located on the rear panel of the amplifier give you a direct output feed which faithfully captures the entire sound of the amp and preamp and can be regulated to properly match anything from a mixing board to a power amp to another Boogie for a linked up arrangement. Although a few mixing boards (mainly Yamaha) won't properly accept the Slave Output signal and cause distortion, an absolutely noise free recording can be made with most other mixers.
