REVERB is a simple depth control which activates the rich all-tube, three-spring analog circuitry. Even though many players have
more modern digital reverbs and delays, there is still something quite pleasant about this natural-sounding,
traditional Reverb system that we think you’ll enjoy. The REVERB effect may seem more intense in some
modes (such as RHYTHM 1) than in other modes, because each mode has a slightly different EQ character-
istic and attack dynamic. This represents normal REVERB operation and is no cause for concern.
The 1/4" jack on the Rear Panel labeled REV FTSW. (as shown in the illustration) allows you control of the
REVERB remotely when the (optional) Mesa/Boogie REVERB footswitch is connected. See your nearest
Boogie Pro Center for this item or call us directly we’ll be happy to assist you.
This feature was explained earlier in the Graphic EQ section of this manual. Refer back to it if you need help understanding what the
function of this switch is.
Mesa/Boogie offers two different Satellite companion amplifers that enable you to either reinforce your already amazing tone, or split
and process the signal using the Effects Loop. A simple 60 watt version called the Satellite Sixty, as well as a 75 watt Simul-Class with
Graphic EQ make up this supportive duo with the Simul-Satellite being the obvious
choice for most MARK IV owners. In the popular stereo scheme, a processors’ Out-
puts feed the two Returns ( Left and Right ) on the MARK IV’S Rear Panel and the
Left Return is then sent on to the matching Satellites’ Input via the Satellite Send jack.
This buffered line may then travel across the stage with little or no tonal degradation
due to cable length or impedance mismatching.
The MARK IV has the ability to control the Simul-Satellite’s Five Band EQ remotely
and automatically - tracking the auto assign function and the Footcontroller choices as
they are used aboard the MARK IV. In this way every nuance and setting of the master amp is relayed to the slave amp creating a
truly awesome spread tonally and dynamically.
This section of the MARK IV is quite sophisticated, offering two LOOPS and a selector switch. The LOOP labled NORMAL stays on
all the time. The other LOOP is switched IN or OUT of the circuit by either the footswitch, the programming rocker switches or the
external jacks (when the MARK IV is being controlled by a MIDI switcher). Notice that if the switchable
LOOP is turned on by the rockers or the external jack, the footswitch cannot turn it back off. Two rocker
switches are provided so you can pre-set the LOOP to come on in conjunction with any one or two modes.
(If an effect is desired on all three modes, use the NORMAL LOOP.) The LOOPS were designed in this way
so you can automatically have your effects in when selecting, say, RHYTHM 1 and/or RHYTHM 2, yet still
