9.0 WARRANTY
The MP-1 (excluding tubes) is warranted against defects in material
and workmanship for a period of three hundred and sixty-five (365)
days from date of purchase. Original factory-installed tubes are
warranted against defects in material and workmanship for a period of
ninety (90) days from the date of purchase. ADA will replace defective
parts and make necessary repairs at no charge if factory inspection
reveals faulty workmanship or material. Neither MP-1 nor tube
warranties cover damage due to misuse, accident or neglect. ADA
retains the exclusive right to make such determination on the basis of
factory inspection. Products returned to the factory must first receive
authorization from ADA and must be shipped prepaid. The “return
authorization number” must be printed on the outside of the container
or the shipment will not be accepted by ADA. This warranty remains
valid only if repairs are performed by ADA, and provided that the serial
number on the unit has not been defaced or removed. This warranty is
expressly in lieu of all other warranties either expressed or implied.
9.1 OPTIONAL EXTENDED WARRANTY
An optional three year warranty is available on the MP-1 if the
extended warranty protection policy is purchased within the first 90
days of purchase. The policy covenants and restrictions are the same
as our standard one year warranty, only the term is increased an
additional three years after the original factory warranty expires.
Enclosed is an application for the extended warranty protection policy.
9.2 TUBE REPLACEMENT
Your factory installed 12AX7 tubes should last approximately
two years. Since these are not power tubes, the lifespan is probably
longer than you expect. When tube replacement becomes necessary,
we recommend that you use only ADA factory - tested replacement
tubes for the cleanest and quietest performance possible. These can
be obtained from ADA or an authorized ADA dealer. For more
information, call ADA Customer Service.

3.0 INITIAL SET-UP
1 Set MP-1 rear panel POWER SWITCH to OFF.
2 Connect your guitar to the front panel INPUT jack. If you are
connected to a professional mixing console, run your signal source
to the LINE INPUT on the rear panel. If both inputs are connected,
only the front panel input will be operative.
3 Connect MP-1 OUTPUTS to your amplifier or mixer inputs.
4 If MP-1 outputs are connected to a power amp or other line input,
flip the top panel slide switch towards the rear panel to the LINE
position. WARNING: Do not use LINE position when MP-1 is
connectd to guitar amplifier inputs.
5 If using MIDI:
A. Connect the MIDI Out of your MIDI footswitch or other MIDI
controller to the MIDI IN jack on the MP-1.
B. When using a MIDI device before the MP-1 and a MIDI device
following the MP-1, use the MIDI Thru jack to send the external
program number. Use the MIDI Out jack to send the MP-1’s
internal memory number.
C. When using the MP-1 as the first in a series of MIDI devices,
use the MIDI Out jack to send the MP-1’s internal memory number.
6 If you own the optional MC-1 MIDI footswitch, connect the MIDI In
Jack on the MP-1 to the MC-1 with the MIDI CABLE. You can use a
standard 5-pin MIDI cable and plug the AC ADAPTOR into the
MC-1
or
you can use the ADA 7-pin phantom MIDI cable and power
the MC-1 thru the 7-pin cable (eliminating the need to have power
near the footcontroller); when using the 7-pin cable, the AC
ADAPTOR plugs into the 9V AC / DC jack on the MP-1 rear panel.
7 If you are using effects with the MP-1, connect the EFFECTS LOOP
SEND jack to the input jack of the first effect in use.
8 Connect the EFFECTS LOOP RECEIVE jack to the output of the
last effect in your loop.
9 See Section 3.4 for full description of correct effects loop level
settings.

By sending in your warranty card, you are entitled to one free EPROM
software update. Thereafter, updates are $50 each. You can send your unit to
ADA for installation or we can send you the EPROM. Always refer to qualified
service personnel for installation.
When you power-up the MP-1, the software revision level is indicated on
the LED Readout before the word “ADA” flashes.
Level 1 software offers the following features: 100% compatability with
MIDI Spec 1.0. In addition, ADA has pioneered a phantom power system which
sends AC power thru a 7-pin MIDI cable to controllers such as ADA’s MC-1 MIDI
CONTROLLER.
Level 2 software offers upload and download of MP-1 parameters to
computers with a MIDI interface using System Exclusive Messages. In addition,
MP-1 parameters may be accessed in real-time using SYSEX messages.
Level 3 software will read MIDI Timecode for synchronizing with SMPTE
Time Code devices, and will be able store a Q-LIST of MTC program and
parameter changes.
These are the updates that we now know about. As MIDI evolves, so will the
MP-1. its capabilities will continue to expand!

3.2 EDITING AND STORING PROGRAMS
The EDIT function is used to look at specific parameter values
and to create or modify a program
The STORE function is used to take the program you are
listening to in the Working Register and store it in a specific internal
memory number location. There are 128 locations.
To save your own
programs, you must use the STORE function. If you do not STORE
an edited program, it will be erased when you select a different
program.
When EDIT is pressed , the display reads “Edit”. From the
beginning of an edit session until the newly edited program has been
stored or abandoned, the MIDI interface is disabled. This prevents a
MIDI selected program from overwriting an edit session. Pressing the
EDIT button will exit the edit session. If you want to save your edit
session, press the STORE button to put the unit into the Store mode. If
a change is made to a parameter while in the Edit mode, the EDIT LED
will blink until the Edit mode is exited to remind you that if you don’t store
the program you will lose it if you select a different program to listen to.
The memory number will blink until the new data has been stored or
abandoned.
Once in Edit mode, pressing a parameter button selects an
alternate function for editing, illuminates the associated LED and puts
the current value on the display. Pressing the ∧ ∨ buttons will increment
or decrement the displayed value. If the button is held down, the display
value will increment or decrement until the maximum or minimum value
is reached.
EXAMINE PROGRAM PARAMETERS
1 Press BANK, press ∧ ∨ buttons until 0 is displayed on the tens digit
of the display, then press 1. You are now in program 1.
2 Press EDIT button.
3 Choose the OVERDRIVE 1. The value “5.0” is displayed on the LED
READOUT. Next, choose OVERDRIVE 2, its value is “5.0”.
Continue this process by examining MASTER GAIN, BASS, etc. An
LED on each button “blinks” when the parameter has been selected
for modification.
4 Press the EDIT button when you are through examining the
parameter values. The EDIT LED will turn off, and you will be
returned to Program 1.

In the SOLID STATE mode, OVERDRIVE 2 functions as your
compression control. The higher the value, the more compression you
have, to a maximum of approximately 40dB. Use the compression to
soften your attack and achieve better sustain.
The MASTER GAIN sets your pre EQ level. When the MASTER
GAIN button is selected, the ∧ ∨ buttons will change the value from 0 to
10. As you create programs (the EDIT LED on), any change of the
VOICING mode will reset the MASTER GAIN level to 0. This is
necessary to supress any loud surprises.
The stereo analog CHORUS is a perfect complement to the
warmth of the MP-1’s tube circuitry, but it will do more than produce
great chorusing. If you set the CHORUS RATE to 0 (off), the CHORUS
DEPTH functions as a very short delay, producing a wide range of notch
filter and doubling effects. You can achieve a hollow, out-of-phase
“Strat”-type sound, and fine-tune it by taking the CHORUS DEPTH value
up or down.
3.4 USING THE CLIP LED’S
Your MP-1 is digitally controlled. The MP-1 circuit is monitored in
four points for clipping of the digital controls to help you prevent
unwanted kinds of distortion from coloring your tone. Always pay
attention to your CLIP LED’S. If a CLIP light remains on while you play,
you should lower the value of the control that is indicated. If you like the
tone that you have, you can still keep that tone, but eliminate the
unwanted clipping.
For example, if the EQ is clipping, but you want the same curve,
you can either lower the MASTER GAIN (signal going into the EQ), or
lower all of the EQ values the same amount.
3.5 USING THE EFFECTS LOOP
The EFFECTS LOOP LEVEL control on the rear panel will allow you to
achieve the quietest possible performance, no matter what kind of
effects you are using. The level control is configured to insure that you
have the same overall signal level whether the effects loop is in or out,
provided the effects in the loop are set for unity gain.
SELECT PROGRAM & MEMORY NUMBER
1 Connect the MIDI Out of a MIDI device to the MIDI IN jack on the
MP-1. Test if reception is occurring by changing programs on the
sending device. As you change programs on the external device, the
MP-1’s LED display will change.
2 Press PRGM. The LED flashes.
3 Select a new PRGM number by (a) scrolling through the program
numbers with the ∧∨ buttons, or (b) go directly to a program using
the BANK, ∧∨ and 0-9 buttons.
4 Press MEM. LED flashes.
5 Select a new MEM number by (a) scrolling through the program
numbers with the ∧∨ buttons or (b) go directly to a program using
the BANK, ∧∨ and 0-9 buttons.
6 Press MEM to store and exit.
4.1 ONE-TO-ONE MAPPING
The MP-1 is shipped with a 1-to-1 program / memory map, i.e.,
external MIDI program 1 is mapped to internal memory 1, external 2 to
memory 2, etc. If you want to restore the 1-to-1 relationship:
1 Press STORE. STORE LED will blink.
2 Press BANK, hold down and simultaneously press 2.
Display reads “Load”.
4.2 REMOTE
The ADA MC-1 is a universal MIDI CONTROLLER that permits
sending program change commands to the MP-1 and the rest of your
MIDI equipment.
Two options exist for using the MC-1 with ADA equipment. First
you can use an ADA 7-pin MIDI CABLE to phantom power the MC-1.
This prevents the need to run AC power to the footswitch (the AC
ADAPTOR is connected to a jack on the rear of the MP-1 labeled 9V
AC/DC). Second, you can use a standard 5-pin MIDI cable and plug the
AC ADAPTOR directly into the MC-1.

4.0 MIDI FUNCTIONS
The MP-1 has MIDI In, Out and Thru and recognizes program
change, SYSTEM Exclusive and MIDI Time Code.
To send and receive MIDI data, you must select a MIDI channel.
You have the option of selecting an individual MIDI channel, (1-16), or
you can send or receive on all 16 MIDI channels (OMNI) or you can turn
MIDI off.The MP-1 has 128 storage registers for programs. These are
referred to as “internal memory”. The MP-1 allows you to “map” MIDI
program numbers received via MIDI IN to any “internal memory”
numbers you choose. For example, if you have a MIDI foot controller
connected to the MP-1, sending program change 11, the MP-1 could
“map” the reception of program 11 to memory 22 or any memory
location from 1 thru 128 in the MP-1. This gives you the potential of
“mapping” more than one MIDI program command to the same MP-1
memory number. Other MIDI devices without this feature limit you to a
one-to-one relationship, e.g., when you change to program 11 on your
foot controller, the receiving device can change only to program 11.
When the PRGM or MEM buttons are in use and their
corresponding LED is flashing, the MIDI interface is temporarily
disabled. If the MP-1 is left with the PRGM button active, the MP-1 will
display program numbers when they are received instead of internal
memory numbers.
The external MIDI PRGM number range is from 1-128. The
internal MEM number range is from 1-128.
SELECT MIDI CHANNEL
1 Press MIDI CHNL. To select a number from 1 thru 16, ALL (OMNI),
or MIDI OFF, use the ∧∨ buttons to make your selection. When the
display reads “ALL”, the MP-1 will talk and listen to all 16 MIDI
channels simultaneously. When the display reads “OFF”, the MP-1
will not talk or listen to any MIDI channel.
Be sure to set the MIDI
device connected to the MP-1 to the same MIDI channel as the
MP-1.
(If you do not know the MIDI channel being sent by the device
preceeding the MP-1, set to ALL).
2 After selection has been made, press MIDI CHNL to save and exit.
Follow this general procedure:
1 If you are using an effect with only one level control, set your effects
device to unity gain. You can test for unity gain by connecting the
EFFECTS SEND to your effect input, and running the effect output
directly to your amp. Adjust the level on your effects device so that
you have the same volume when the effect is switched in or out.
2 Set the EFFECTS LOOP LEVEL at the highest possible setting
without clipping the effect’s input.
3 If you are using a line level effect with two level controls, set your
EFFECTS LOOP LEVEL control to 1 o’clock (0 dB gain). Adjust the
input level on your effect to the highest possible setting without
clipping, and set the output level control on your effect to achieve
unity gain in your effect. You can test for unity gain as described in
step 1.
4 Check for distortion and excess noise. If your effect is clipping, turn
your EFFECTS LOOP LEVEL control counterclockwise.
3.6 LOAD PRESET PROGRAMS
There are 29 factory preset programs (1-29) that can be loaded
into the internal program memory via the front panel. These can be
loaded at one time, or they can be brought into the MP-1’s working
register one at a time (Level 2 software). To load all 29 programs, press
the STORE button. The STORE button will blink. Press BANK and, while
holding it down, press 1. Display reads “LP” (Load Programs). Programs
1 thru 29 will be erased and overwritten by the preset programs.
Reference section 6.0 MEMORY PRESET SETTINGS for a description
of factory presets. To load just one program (Level 2 sofware), press
BANK and while holding it down, press CHORUS RATE. “P” will be
displayed, indicating that a preset is being recalled. Now select the
preset you want by using ∧∨. You may use or edit this program without
erasing any of your own programs, or you may save it by using the
STORE sequence.

5.0 SELF DIAGNOSTICS
The MP-1’s self-diagnostic program checks the unit for errors
during power-up. This interactive feature pinpoints the source of
problems to simplify correcting the problem.
The following chart shows the error code that will be displayed in
the event of a problem, the cause of the problem, and the appropriate
action for you to take. ERROR CODES
DISPLAY CAUSE ACTION
Err 1 MIDI map checksum error. All
MIDI program numbers are set
1:1 with internal memory
numbers.
Re-enter MIDI
map
assignments.
Err 2 Working register checksum
error. All values of stored
parameters in the working
register are set to default
values. All are set to 0 except
effects loop is set to “out” and
the clean channel is selected.
Call up another
program
number or re-
enter parameter
values via Edit

EDIT AND STORE A PROGRAM
1 Press the EDIT button.
2 Choose a parameter such a s MASTER GAIN and decrease or
increase its value with the ∧∨ buttons.
3 Proceed to the next parameter following the same procedure as 2 .
above.
4 After all changes are complete, press the red STORE button.
5 Increment or decrement to a bank number, and select a memory
number from 0 - 9 that you want to assign to the program. The
program is now stored in the selected location.
3.3 CREATING TONE
When the EDIT button is toggled on, you have access to the
MP-1’s gain and tone controls ( gray area ). The MP-1 has a unique
VOICING control which allows you to create programs using ultra-high-
gain DISTORTION TUBE ( display reads
TUBE with DIST LED lit on
the far left of the display ), CLEAN TUBE (
CLEAN LED lit ), or SOLID
STATE ( display reads S.S. ). When the VOICING button is selected,
use the ∧∨ buttons to access these three choices.
The DISTORTION TUBE voice filters the pre-tube input signal
for super-saturated distortion. The processor control biases the tubes for
extra high gain tone. When the CLEAN TUBE is selected, the processor
re-biases the tubes for clean tones. It also re-filters the input signal to
give you full-range frequency response for warm Fender- type sounds.
The SOLID STATE voice bypasses the tube circuitry. This will give you a
complete range of solid state sound, including chorus, adjustable
compression, and notch filtering.
When setting your OVERDRIVE levels, remember that low
levels followed by high levels produce more noise than the reverse. High
levels of OVERDRIVE 1 will produce a distortion that has high frequency
harmonic saturation, whereas high levels of OVERDRIVE 2 will produce
fuller harmonic saturation. When OVERDRIVE 1 or OVERDRIVE 2 is
selected, use the ∧∨ butons to change the levels from 0 to 10.

proper level setting is necessary. If a CLIP LED remains on as you
play, an adjustment of the program setting is necessary. See Section
3.4 for a complete description.
3.1 ACCESSING PROGRAMS
The MP-1 is shipped from the factory with 29 preset programs.
Please note that the amount of overdrive in any program will depend on
the type of pickups you are using. For example, single coil pickups will
require higher levels of OVERDRIVE 1 than hotter dual-coil pickups to
achieve the same amount of distortion. See Section 3.3.
As you store your own programs into memory locations, you
erase the formerly stored program values in the respective registers.
However, you can always recall the original factory preset programs, so
feel free to experiment.

1.0 INTRODUCTION
Thank you for purchasing the ADA MP-1 MIDI Programmable
Tube preamp. You now own the most tonally flexible and technologically
advanced guitar preamplification device available. Your MP-1 will store
128 programs of exactly the right tone, no matter what kind of music you
play. The MP-1 features a unique Tri-State Voicing selection that
allows you to choose between Distortion Tube, Clean Tube, or Solid
State circuits for each program. The EQ points were designed to
replicate the sounds of Fenderand Marshall, but the Presence
control surpasses the range offered by either. The Stereo Chorus utilizes
analog circuitry which complements the warmth of tubes to give you the
best possible sound.
The software in the MP-1 provides the fullest implementation of
MIDI available. Since the MP-1 is software based, it will never grow
obsolete. As the MIDI standard evolves, your MP-1 can be updated by
simply changing the program ROM. In the manual, you will find
references to different levels of software. When you power up your
MP-1, the display indicates which level of software is installed. On
power-up, “ADA” is displayed first, followed by a three-digit number. The
first of these digits is the level of software installed.
To properly set up and familiarize yourself with the MP-1, read
and follw these operating instructions completely. If you can’t wait, and
want to jump right into the MP-1, go to Section 1.1 QUICK SETUP.
We hope that the unlimited tonal possibilities and unmatched
technological capabilities of your MP-1 will inspire you to great things.
IMPORTANT:
Please take this time to fill out and return the
enclosed warranty card so we may provide you with information on
future software updates.
