Mesa/Boogie M-pulse Simul State Bass Amplifier - Manual (Page 6)

This power is interfaced to you via a pair of Output controls that serve as overall MASTER VOLUMES. These are MAIN and SOLO
and the two astound bassists much as they did when we began including them on our guitar amplifiers. The logic is in their names
MAIN and SOLO. When players get this scheme they say “why hasn’t there always been two”. There will be from now on as imitators
follow, but right now we are giving you another footswitchable feature in the form of this SOLO control. This is an additional Master pot
wired in parallel with the MAIN Output and it allows a footswitchable SOLO boost. This feature lets you step out for a showcased part
or allows you to compensate for a sound that has a lower output due to either notching in the Parametric EQ or Compression or both.
Looking to the Rear Panel you can see that all your interfacing needs are well provided for. A dedicated TUNER Output is provided for
tuning without having to disconnect. The Parallel Effects Loop and MIX control provides seamless interfacing of all your outboard
processing. The Loop is also footswitchable allowing you to call up your effects on the fly.

A Balanced XLR DIRECT OUTPUT and LEVEL control is provided with both Post and Pre settings to capture your sound through
house main or recording consoles. In addition a SLAVE Output with LEVEL control is provided capturing both pre-amp and power
section in a padded format. This enables you to use additional power for large venues or for deriving a post signal for effects to be sent
to additional amplifier(s) in a 1 dry / 1 wet scenario. And finally, 2 SPEAKER OUTPUTS are provided to harness the robust output of
the
M-PULSE power amp. With this pair of jacks almost any speaker cabinet or combination of cabinets can be accommmodated.
Now that we have covered the basics of your new M-PULSE, let’s connect up the A.C. and your favorite cabinet and Bass and give
this instrument of fundamental enlightenment a listen with a quick reference setting.
