OVERVIEW: Congratulations on your choice of the M-PULSE as your Bass amplifier . This latest offering is our most comprehensive amplifier for electric bass and it brings together both new and old technology , solid state and vacuum tube design to create an instrument of unparalleled performance and soulful sound. M-PULSE amplifiers start with an al[...]

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”. Th[...]

P AGE 3 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. Y ou 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. Mi[...]

FRONT PANEL: INSTRUMENT INPUTS: ACTIVE / PASSIVE These are the Instrument Input jacks and between them you can match the signal output level of virtually any instrument. The ACTIVE Input 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. Usually these ins[...]

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 ei[...]

FRONT PANEL CONTROLS: (Continued) TREBLE: Continued retaining all the necessary cut and focus associated with a traditional passive TREBLE control. As the control is dialed below 12:00, it begins a 6db per octave cut from 3.2Khz to the shelving point at 723Hz, where it continues to attenuate all frequencies above 723Hz until - 20db is reached where[...]

FRONT PANEL CONTROLS: (Continued) GAIN CONTROLS: Parametric EQ Continued expect to have a great sound. Make small moves and then allow your ears time to adjust to the difference. With controls this powerful, EQ Hangover is a part of the buzz. Don’t be surprised if after t weaking for an hour with the P ARAMETRIC, you go back to your starting poin[...]

FRONT PANEL CONTROLS: (Continued) COMPRESSION: This section of your M-PULSE controls the processing of dynamics and this in turn, feeds the SIMUL- ST A TE 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. Most experienced[...]

P AGE 9 FRONT PANEL CONTROLS: (Continued) RATIO: Continued From 12:00 on up to the maximum setting of “00” (Infinity) is reached at 5:30, an extremely powerful compres- sion effect is produced - at which point the signal is fully compressed. There are very few times you will ever need this much compression, but if you ever do, it is all here in[...]

P AGE 10 REAR PANEL CONTROLS: FUSE: This is the A.C. Mains Fuse for the M-PULSE REPLACE ONL Y WITH A SLO-BLO TYPE FUSE OF THE PROPER RA TING. THIS IS EXTREMEL Y IMPORT ANT , AS THE M-PULSE DRA WS A SUBST ANTIAL AMOUNT OF CURRENT A T HIGH OUTPUT LEVEL SETTINGS. AC RECEPTACLE: The removable “Euro” Style” A.C. cord that is supplied with the M-PU[...]

P AGE 1 1 REAR PANEL CONTROLS: (Continued SLAVE OUT: This 1/4" jack and control provide a signal derived from the speaker jack. Perfect for using the M-PULSE as a master pre-amp, or slaving to additional power amps for more power when needed. Some players use the SLA VE to derive an FX Send Signal and go to other amps for their wet sound. NOTE[...]

REAR PANEL CONTROLS: (Continued EFFECTS: The EFFECTS LOOP section of the M-PULSE is responsible for handling the interfacing of external signal process- ing. It is also comprised of four elements and they are; (1) a SEND jack, (2) a RETURN jack, (3) a MIX control and (4) a Program switch. Their functions are as follows; SEND: This is the output of [...]
