Solo Control; Standby Switch; Power: Bold/Off/Spongy Switch - Mesa/Boogie Roadster Owner's Manual

CONTROLS:
SOLO:
This control is an additional output control wired in parallel with the main OUTPUT that you can pre-set to a higher level
and then switch to during performances. A simple idea that adds amazing potential to virtually any sound in the amplifier. Like the

STANDBY:
Perfect for set breaks... this toggle switch also serves an even more important purpose. In the Standby position the
tubes are at idle so that during power up they may warm up before being put to use. Before Power is switched on make sure the
ON BOLD
STANDBY SPONGY
POWER: BOLD / OFF / SPONGY
works like a built in Variac, reducing all the internal voltages for a true vintage feeling and that extraordinary "brown sound." Power is
reduced somewhat too, making it easier to achieve an overdriven power sound, especially when the RECTIFIER SELECT switch is

STANDBY SPONGY
Follow the cold start procedure described in the STANDBY section above when powering up your new Roadster.
Now that we have reviewed the Channels and their Modes we are ready to go aft and check out the treasure chest of features that
ride the Rear Panel.

OUTPUT control, SOLO gets its signal from the EFFECTS RETURN jack and therefore it is only
in the signal path and active when the EFFECTS LOOP is set to LOOP SYSTEM IN. This control
may be used to step out for a solo or to compensate for other volume drops created by various
switching scenarios. One might be a processor that you love the sound of, but steals gain from
your signal when introduced via the LOOP. However you choose to use this valuable feature,
SOLO adds power and versatility to an already mighty package.
NOTE: As mentioned above, when using the Roadster as a slave power amp the SOLO control
can be used to provide a footswitchable volume boost for the power amp.
STANDBY switch is in the Standby position. Wait at least 30 seconds and then flip the STANDBY
switch to the ON position. This prevents tube problems and increases their toneful life substantially.
This three position toggle switch determines the status of the incoming AC power. "SPONGY"
set to the TUBE RECTIFIER position.
Using the Roadster in the SPONGY power setting will also extend tube life and overall reliability,
while still producing enough power to work many of your gigs...and all of your recording needs! For
maximum power, normal response and the greatest headroom use the BOLD setting of the AC
power switch.
Make sure the unit is grounded (all three terminals of the A.C. power cord must be connected when-
ever possible to avoid injury to the user as well as to the unit) and that the proper voltage is present.
