HookupDiagrams
The MDB-1P is a convenient direct box for musicians – especially bass players – to add to the chain.
Let’s look at the front panel connections first. Start by simply connecting your instrument to the MDB-1P
input jack. And end by simply connecting a cable from the thru jack to your amplifier’s input jack.
Front panel connections made!
The rear panel connection is as straighforward as the front panel connections. Here we connected
an XLR cable from the MDB-1P output jack to a mixer’s input jack.
That was our part. The next part is up to you... the audience is waiting!
Note: While we used a Mackie ProFX12v2 mixer in this example, you could connect the output of the MDB-1P
to the input jack of an audio interface instead. The Mackie Big Knob Studio and Studio+ come to mind!

The MDB-2P direct box works great for musicians with stereo instruments. In this example, we connected
a synthesizer to the MDB-2P lef and right input jacks. The thru jacks are then connected to the keyboard
amplifier’s input jacks.
Unlike the other MDB Series Direct Boxes, the rear panel of the MDB-2P has dual L/R output jacks for
connecting XLR cables between the MDB-2P and a mixer’s input jacks.
Your fantastic fans await your memserizing music and tasteful tunes. Time to stop reading...

HookupDiagrams
Here we connected a six-string guitar to the input jack of the MDB-1A. The thru jack is then connected to
an amplifer, BUT... you have options! If the merge switch is turned on, the thru jack works as a second input
which works great for stereo instruments such as synthesizers and other media players.
The rear panel of the MDB-1A is exactly the same as the MDB-1P except with two additional switches. Like the
MDB-1P, we connected a single XLR cable from the MDB-1A output jack to a mixer’s input jack.
Listen to the sound to determine if the polarity switch should be at 0˚ or 180˚ and if the low cut switch should
be turned on or lef o.
Note: While we used a Mackie ProFX12v2 mixer in this example, you could connect the output of the MDB-1A
to the input jack of an audio interface instead. The Mackie Big Knob Studio and Studio+ come to mind!

1. Input Jacks
The signal output from an instrument (active
or passive) may be connected to this unbalanced
line-level 1/4” input by means of a shielded instrument
cable. This includes guitar, bass, keyboard, media
players and more.
They are wired as follows, according to standards
specified by the AES (Audio Engineering Society):
Unbalanced 1/4" Input Connector
Tip – Positive (+ or hot)
Sleeve – Shield (ground)
NEVER connect the output of an amplifier
directly to an MDB Series Direct Box’s input
jack. This could damage the input circuitry
and we wouldn’t want that now, would we?
2. Thru Jacks
The Thru jack may be connected to the input
of an instrument amplifier or instrument-level
parallel eects device (such as an FX device chain,
processors, or tuner). This output is unaected
by the MDB Series Direct Box’s circuitry.

3. Pad Switch
Put this switch in the down position to reduce
the input signal by 15 dB and compensate for higher
output sources. This attenuation is suited for use with
instruments that have active electronics or high-output
pickups.
It is a 20 dB pad on the MDB-1A and the
switch is reversed from the MDB-1P and
MDB-2P; –20 dB in the up position, 0 dB
when the switch is down.
4. Merge Switch [MDB-1A]
When the Merge switch is in the OFF position
(switch up), the Thru jack works as normal
(see #2 description, bottom-lef).
When the Merge switch is in the ON position (switch
down), the Thru jack works as an additional input.
It will be summed with the main input to create a mono
output source. This is a perfect solution for stereo
sources like keyboards and media players.
Additionally, the associated LED will illuminate
when merge is on.
MBS On / O Switches
The rare and highly sought afer MBS–FNMA and
MBS–GNMA Direct Boxes come with switches to turn
o your mind, body and soul when any (or all) of them
need it. When will you know? Oh, you’ll know. When it’s
there, simply flip the switch to o and when you’re
feeling good again, go ahead and flip the switch back
to the on (up) position.

5. XLR Output Jacks
These XLR connectors provide a balanced line-level
signal that is designed to connect to the inputs of a
mixer or audio interface.
They are wired as follows, according to standards
specified by the AES (Audio Engineering Society):
Balanced XLR Output Connector
Pin 1 – Shield (ground)
Pin 2 – Positive (+ or hot)
Pin 3 – Negative (– or cold)
6. Ground Lif Switch
The ground lif separates the chassis ground from
the signal ground at the balanced output jacks. The
default position is ground. You may attempt to remedy
system ground loop hum by moving the switch to lif.

7. Low Cut Switch [MDB-1A]
When on, the low-cut switch (ofen referred to as a
high-pass filter) cuts bass frequencies below 120 Hz.
We recommend that you use low-cut on every
microphone application except kick drum, bass guitar,
or bassy synth patches. These aside, there isn’t much
down there that you want to hear, and filtering it
out makes the low stu you do want much more crisp
and tasty. Not only that, but low-cut can help reduce
the possibility of feedback in live situations, and it
helps to conserve amplifier power.
Another way to consider low-cut’s function
is that it actually adds flexibility during live
performances. With the addition of low-cut,
you can safely use low equalization on vocals. Many
times, bass shelving EQ can really benefit voices.
Trouble is, adding low EQ also boosts stage rumble,
mic handling clunks and breath pops from way-down
low. Applying low-cut removes all those problems,
so you can add low EQ without blowing the woofers.
8. Polarity Switch [MDB-1A]
When this switch is up, it reverses the polarity of the
signal by 180˚.
There is no right or wrong setting for this switch.
Listen to the overall blend with the rest of the system
and select the switch position that gives you the best
sound for your audience. In fact, your system may vary
when positioned dierently and in alternate venues.
Don’t be afraid to experiment with the position of the
polarity switch.

Nosound
• Is the level knob for the input source turned all the way
down? Verify that all the volume controls in the system
are properly adjusted. Look at the level meter to ensure
that the mixer is receiving a signal.
• Is the signal source working? Make sure the connecting
cables are in good repair and securely connected at both
ends. Make sure the output level control on the mixing
console is turned up suciently.
• Make sure the mixer does not have a mute on or a
processor loop engaged. If you find something like this,
make sure the level is turned down before disengaging
the oending switch.
Poorsound
• Is it loud and distorted? Make sure that you’re not
overdriving a stage in the signal chain. Verify that
all level controls are set properly.
• Be sure all connections are secure.
Hum
• Whenever possible, plug all the audio equipment’s line
cords into outlets which share a common ground.
The distance between the outlets and the common
ground should be as short as possible.
