M700 Bass Amplifier
This is all fun. The M700 Bass Amplifier is here to make sure you and your audience can feel
all the love and creativity that is in every note you play.
The M700 is designed to be simple.
The Front of your M700
The Input jack on the right is designed to accept the ine evel output from Monique. It will
also accept an instrument level as low as -26db. That means you can play your Bass directly
into your M700 if you must.
The Black knob is a Volume knob. Clockwise is full volume and Counter Clockwise is off.
The Power Switch is on the left with a B UE “Power-On” light next to it.
There is a power-on sequence that will take a few seconds each time you flip the Power
Switch to the “on” position. The B UE “Power-On” light will come on immediately, but you will
have to wait a few seconds to get full power.
All you have to remember is that it will take about 5 seconds before you can play, and there
will be two lights on the front of your M700 when it is ready to make music. ights will flash
on and off, but when your M700 is ready it will look like this:
Both the B UE “Power On” light and the GREEN “Ready” light will be illuminated. The other
two lights, the RED “DC Failure” light will extinguish and the second B UE light (between the
RED and the GREEN) will be out.
The reason for the delay after you turn up that Power Switch is that some serious testing is
done each time you use your M700. With 700 watts available, we want to make sure
everything is as it should be before we turn everything up.
The RED “DC Failure” light will always be illuminated early in the power-on sequence. That
means it is doing its job of detecting a power imbalance. Once the power is balanced, the
RED light will go out.
You will notice that the RED “DC Failure” light also stays on for a long time after you power
down your M700. Again, it is doing its job of detecting a failure (there is no power). The RED

“DC Failure” light can stay illuminated long after the power is turned off because of the huge
amount of voltage storage available in the M700. If the RED “DC Failure” light comes on at
any other time, for example while you are playing, it means that some serious failure has
occurred in the amplifier.
Between the RED and GREEN lights is a B UE “Clip” light. This is set to come on pretty early.
It is expected that you will see the B UE “Clip” light occasionally. A B UE “Clip” light that is
flashing occasionally is not unusual.
If you are pushing the M700 enough to keep that B UE “Clip” light on all the time, you will
need to back off your input to the M700. Keeping your input high enough to peg that “Clip”
light will eventually be detected as an error by the M700 and it will shut down until a correct
level is restored. Just back your Volume off a bit and keep playing.
The Back of your M700
Both the Speakon Jacks are in parallel. Optimum mpedance is 4 ohms. Minimum
mpedance is 2 ohms.
You can achieve 4 ohms speaker impedance with a single 4 ohm cabinet, and you can
achieve 4 ohms speaker impedance with a couple of 8 ohm cabinets.
Both the Speakon Jacks are “Combo” jacks. They will take a 1/4” jack if you are left with only
that option. It is strongly advised that you use the Speakon Jacks and heavy speaker cables.
Even the best 1/4” Speaker Jack has greatly less contact area than a standard Speakon Jack.
That additional contact area is important to have with 700 watts available.
What happens if you have to run at 2 ohms (for example with a couple of 4 ohm cabinets)?
1. You have about 1200 watts of available power at 2 ohms.
2. For short durations, you will have no problems at 2 ohms. The difficulty is that
everything begins to heat up quickly at 2 ohms. There are already players doing three
and four hour performances with the M700 at 4 ohms. We know that is stable.
3. If we go to 2 ohms and turn everything up full, we are in uncharted waters. By that I
mean we can not guarantee the best performance.

My advice is to run at 4 ohms whenever you can. If you have to run at 2 ohms, know that
that is not the optimum for the M700.
Power nput on the right accepts an IEC jack.
The power cable is an important part of the sound and character of your M700.
US, Canadian, and Mexican customers are provided with a heavy duty power cable. Because
of the variety of Power Connections around the globe, International Customers must
purchase their IEC cable locally.
Plugging your M700 directly into a power outlet is always going to be better than into a
Power Strip or Extension Cable.
nternational Customers, make sure your power cable has internal wiring no less than 18
gauge. An easy way to tell if it has enough wiring to do the job is to feel its weight. If it is
much heaver than a printer or computer cable it is probably OK.
If your IEC cable does not fit tightly into the receptacle on your M700, do not use it. It must
fit tightly. Please stay away from inexpensive IEC power cables made for computers and
printers.
There is a safety fuse inside the IEC receptacle on the back of your M700. That fuse is a 15
amp fuse. Never increase the size of that fuse. If the fuse blows it is telling us that something
is wrong and must be addressed.
Fan Switch is there for those times in the studio when even the most quiet ventilation fan
can not be tolerated. Please use the fan whenever you can, especially for live performances.
That means keeping the “FAN” switch in the up position. You probably will not be able to hear
the fan, but it is there working.
If you turn your M700 upside down, you will notice that the entire bottom is textured
aluminum. This aluminum plate by itself dissipates much of the heat developed by your
M700.
If your M700 gets too hot it will safely shut down until it has cooled enough to continue. The
high temperature mark for shutdown is 212° Fahrenheit or 100° Celsius.
ike I said. . . simple.
