Channel Strips; Rectifier Select With Tube-Tracking - Mesa/Boogie Dual Rectifier Roadster Amp Owner's Manual

REAR PANEL CONTROLS & FEATURES

CHANNEL STRIPS:

These 4 clusters of switches and controls house the specific features that can be pre-assigned per individual
channel. Once you have deciphered one, you have learned the Roadster's secret and are ready to roll, for they are simply repeated
for the 4 channels.

RECTIFIER SELECT with TUBE-TRACKING:

converts the voltage from AC to DC for the power supply. The Roadster incorporates a further improved version of our patented
Switchable Rectifier feature first seen on the Dual and Triple Rectifier SOLO heads. It incorporates a Rectifier Tracking™ feature that
insures proper voltage is present at all times and improves reliability. This switch operates in tandem with the individual Channel
Power Select (50/100) switch located in each Channel Strip.
The Rectifier Tracking feature monitors the Channels, determines their power status and automatically selects the proper rectifier
type - which ultimately assures the best sound. This provides optimization of the power settings, delivering a magical tube-rectified
power-sag vibe for the channel set to 50 watts - and a tighter, bolder 100 watts of diode-rectified authority for the channel set to full
power. Here is an explanation of how the two choices work;
DIODE:
Calls up the silicon diode rectifier, which offers more punch, a tighter attack with more brightness and substantially more
headroom. This rectifier choice provides the highest power and therefor the tightest rectification. This setting would be best for any
application where maximum headroom is needed or tight bass response is called for. Situations that usually require this are clean
rhythm playing or extreme high gain crunch rhythm sounds.
RECTO TUBE-TRACKING:
the tight, bold authority of the Silicon Diodes. Selecting RECTO TRACKING brings on-line one 5U4 when in 50 watts and two 5U4s
when 100 watts is selected.
The tube rectifier sound takes a power section walk down memory lane, paying tribute to those vintage gems of yesteryear. In those
early days of amplification the only rectifiers available were tubes. Unbeknownst to their creators, these sweet sounding amplifiers
would someday become relics as the demand for higher volumes and more power per package led to the abandonment of the tube
as a rectifier, in favor of the five cent silicon diode's greater efficiency. With this decision went much of the sweetness and soul and by
the late '60's most amps were bold, loud and efficient...but unfortunately sometimes lacking that earlier soul. We sought to bring that
magic soul, personality and feel to the Dual Rectifier Series, and the resurrection of this age-old circuit does just that.
NOTE: Don't forget the Front Panel AC switch incorporates the reduced voltage SPONGY setting. This adds yet another dimension
to the power expression scenario and can produce amazing results when combined with the RECTO TUBE-TRACKING feature. Be
sure to experiment with these two features in combination with each other.
This section is where you choose the status of the LOOP, your power setting (50/100 watts), the
type of Rectifier you wish to use and your Reverb Mix Level. Each preamp channel has a corre-
sponding CHANNEL STRIP to give you voicing and feel control over each of the four footswitchable
sounds for the ultimate flexibility and maximum tone.
