Make certain grounding conforms with local standards. YOUR AMPLIFIER IS LOUD! EXPOSURE TO HIGH SOUND VOLUMES MAY CAUSE PERMANENT HEARING DAMAGE! Your Mesa/Boogie Amplifier is a professional instrument. Please treat it with respect and operate it properly. READ AND FOLLOW INSTRUCTIONS OF PROPER USAGE. -
Page 5: Overview
M-PULSE amplifiers start with an all-tube pre-amp for the most musical response and this feeds the three standard rotary tone controls BASS, MID and TREBLE. Most first time players comment that we could have stopped right there after hearing the sweet, tight, huge sound from this first section of the M-PULSE pre-amp. -

POWER COMPRESSION MASTER VOLUMES Now that you have had a listen to your M-PULSE, here are a few quick tips to help you in case you don’t have time to read the rest of this manual right now. PAGE 2... -
Page 7: Helpful Hints
1. Connect your A.C. Power Cable to a grounded outlet. Avoid ground lifts (3 to 2 prong adapter) whenever possible. 2. The optimum speaker load for your M-PULSE is 4 Ohms. You may use a cabinet (s) of a higher rating safely (8 Ohm) with no degradation in tone, however the amplifier will not produce its full rated wattage. -

FRONT PANEL: ACTIVE / PASSIVE SWITCH: This switch allows you to match the signal output level of virtually any instrument. The ACTIVE position is padded down for greater input stage headroom and this works well with basses that use an on-board pre- amp with an active tone control circuit. -
Page 9: Gain Bass Mid Treble
FRONT PANEL CONTROLS: (Continued) BASS: This control is responsible for the basic mix of low frequencies in the tube pre-amp. As mentioned earlier in the Helpful Hints section, the BASS control is an active shelving type control as opposed to a passive style control. This means that a center Q point has been chosen and this control allows you to either boost or cut that frequency. -
Page 10: Parametric Equalizer
This active shelving TREBLE control completes the rotary tone control string to create a powerful and extremely accurate network to use as your fundamental platform. It’s no wonder many first time M-PULSE players make the comment that just these controls combined with the GAIN create the best tone they have ever heard! NOTE: As with the BASS control, may we remind you that a control of this type with its increased power should be used with finesse. -

FREQUENCY Control settings within the bands to seem much more powerful and others weaker for the same relevant GAIN setting. This is normal and no, your M-PULSE is not misbehaving. Usually the lowest (40Hz) and highest (6K) are the most susceptible to this - with the most extreme low and extreme high settings on the two controls showcasing this phenomenon. -
Page 12: Compressor
COMPRESSION: This section of your M-PULSE controls the processing of dynamics and this in turn, feeds the SIMUL- STATE power section. It is another powerful tool that should be used with taste as it also has the power to be easily misused resulting in an unnatural sound with slaughtered dynamics. -

POWER: This switch delivers the A.C. power to the M-PULSE. Make sure the unit is grounded (all three terminals of the A.C. power cord must be connected whenever possible to avoid injury to the user as well as to the amplifier). Also, make sure that the proper voltage requirements are present at the A.C. -

Page 15: Slave Out
The M-PULSE provides two 1/4 inch speaker jacks for powering speaker enclosures. The recommended speaker load impedance for the M-PULSE is 4 Ohms at which the mighty SIMUL STATE power section is capable of delivering a whopping 625 watts RMS before clip and peaks of over 2000 watts! A speaker load of 8 Ohms may also be used though the overall power will be reduced to roughly 300 watts using this rate of impedance. -
Page 16: Effects: Send, Return, Mix And Progran Switch
NOTE: The best tonal results are usually found by setting your processors’ Dry/Wet blend at close to 100% and then blending a small amount of this very wet signal back in, by setting the EFFECTS LOOP MIX control on the M-PULSE as close to 10% as possible. -

Much like changing a light bulb, you don’t need a techni- cian to cure these types of minor user serviceable annoyances and in fact, you’ll be amazed at how easy it is to cure tube problems... -
