Operating Instructions

Overview: Congratulations on your choice of the RECTIFIER STEREO 2:100 as your power amplifier and welcome to the MESA/Boogie Family. This 2 rack space unit is born of legendary stock and traces its lineage to the mighty Dual Rectifier Solo Head. Here the stunning performance of the Dual is faithfully recreated in a stereo format that duplicates the power section exactly when the Dual is set to its Silicon Diode rectifier setting. Rectifier tubes were not included in this package, as their size did not permit inclusion along with an overall consensus among players asked, that those needing 200 watts of this type of aggressive power would require the tighter, faster response of the silicon diodes. The eight 6L6 power tubes (4 per side) are fan cooled and kick out 100 watts of all-tube power per channel. Three 12AX7sÕ make up the driver section and these are housed inside the unit. Preamp tubes used in this manner rarely wear out as there is little or no exposure to excessive vibration and they are operating under minimal gain require- ments .

The RECTIFIER STEREO 2:100 is a ÒsmartÓ power amplifier as it contains the MODERN Switchable Voicing feature. It responds to a trigger pulse sent by either of its companions, the Rectifier Recording Preamp or the TriAxis Programmable Preamp. When a cable is connected to the MODERN trigger port and this feature is switched via any tip-to-ground type logic, the negative feedback in the power section of the 2:100 is reduced, unleashing a sound of true ferocity. This is a trademark sound in the Dual and Triple Rectifier Solo Heads and has become the most recorded sound in heavy modern rock.
