CHAPTER 2 QUICK START
So you can't wait to plug in your new QUAD TUBE 150M and get some sounds. That's
perfectly understandable, so here is the way to jump right in and get started. Once you get
that far, you'll probably want to explore further. The Tutorial takes you on a guided tour
through the QUAD TUBE 150M, showing the most important features and giving you an idea
how to work with the unit. As you become more experienced with the QUAD TUBE 150M
you will probably need to use the Reference chapter to find out details about specific
features.
1) Be sure Power and Standby switches are turned off.
2) Connect the QUAD TUBE 150M to AC power.
3) Connect your instrument to the QUAD TUBE 150M's Input on the front panel.
4) Be sure the Volume control on the left of the front panel is turned all the way down
(counter clockwise), and the Room EQ control is set to Normal (12 o'clock).
5) Turn on the QUAD TUBE 150M. When the QUAD TUBE 150M is first turned on, it
will take a few moments for the tubes to warm up. After warming up, the QUAD
TUBE 150M will enter Play mode running User program 1. Now turn the Standby
switch to ON.
6) Slowly raise the Volume control and play. Adjust the Volume control to a comfortable
listening level.
7) Use the Up and Down arrow keys to recall programs. The first 39 User programs are
the same as the factory Preset programs.
CHAPTER 3 GETTING STARTED
IMPORTANT: The QUAD TUBE 150M is designed to operate only at the
voltage printed on the back panel. It is not possible to change over or adapt the
QUAD TUBE 150M to operate at any other voltage. Please use an appropriate
external voltage converter when attempting to operate the QUAD TUBE 150M
in a country with a different AC line voltage.
ABOUT TUBES AND THE QUAD TUBE 150M
The incomparable sound of tube amplification comes with the need for a small amount of
simple maintenance to accommodate the nature of tubes.
NOTE: To preserve tube life, allow time for the tubes to cool after shutting down
the QUAD TUBE 150M before moving. Tube elements are more fragile when
hot.
Tubes have a limited life span; it is recommended that the QUAD TUBE 150M's tubes be
replaced about once every 2 years, or if they show signs of wearing out. Some signs of
degrading tube life are:
Excess noise on high gain programs
"Ringing", squealing or feedback
Microphonic effects (tapping on the QUAD TUBE 150M causes audible thumps
through speakers).
Lack of punch and power, "weak" distortion, or sputtering.
Replace the QUAD TUBE 150M's tubes only with high-quality, low-noise 12AX7A-7025
tubes. If desired, these can be purchased from ADA (ADA part # 220020). There are a total
of four tubes in the QUAD TUBE 150M; two in the preamp and one in each power amp
channel.

CONNECTING
The QUAD TUBE 150M
Audio
Input
• Use a shielded guitar cable to connect the guitar to the QUAD TUBE 150M's front
panel input jack. If you are using a tuner for your instrument, plug the guitar into the
tuner and connect the tuner's output to the QUAD TUBE 150M's input.
Output (optional):
• Connect the unbalanced Studio Outputs to the mixing console or recorder's
unbalanced 1/4" phone Line inputs.
• Connect the preamp outs to the inputs of external power amps to power additional
speaker cabinets.
— Or —
• Connect the balanced Studio Outputs to the mixing console or recorder's balanced
XLR Mic or Line inputs. Use the XLR Level switch on the rear panel to set optimum
level range.
• If there is a ground loop causing AC hum in the signal use the GROUND LIFT switch
to disconnect the cable ground shield from the QUAD TUBE 150M's local ground.
NOTE; The QUAD TUBE 150M's outputs are independently buffered. They may all be
used simultaneously, if so desired.
Page 13 of 62
QUAD TUBE 150M OWNERS MANUAL
Effects Loops
• Connect Left and Right Effects Loop Sends to the unbalanced 1/4" phone inputs of
any reverb, effects device, or other signal processor. Use the Mono Effects Loop for
devices that have only a single (mono) input and output. The Mono Effects Loop is
not controllable via software. The Stereo Effects Loop has a software programmable
Status and independent Mix control for each side.
• Connect Left and Right Effects Loop Returns to the unbalanced 1/4" phone outputs of
the reverb, effects device, or other signal processor. When using the Stereo Effects
Loop, set output mix of the signal processor to 100% "wet", since this is a side-
chained effects loop, where the wet/dry mix is controlled in the QUAD TUBE 150M.
• Use the Effects Loop Level switches to set optimum Send and Return levels to match
the external device.
NOTE: Status for the Effects Loop must be set to "In" and the Wet Mix parameter set
greater than 0% for the Stereo Effects Returns to be heard.
MIDI
The QUAD TUBE 150M is capable of responding to MIDI program change and continuous
controller messages. The QUAD TUBE 150M comes standard with the ADA 4x4
programmable MIDI footswitch for program changes. See the 4x4 section on page 17 for an
explanation of its features. ADA also offers the MIDI controller pedal pack (800218) for real
time MIDI control of the QUAD TUBE 150M.
• Connect MIDI In to MIDI Out of ADA 4x4 or other MIDI controller. Any ADA MIDI foot-
controller can be remotely powered using an ADA 7-pin MIDI cable. The QUAD
TUBE 150M features an internal phantom MIDI supply for powering all ADA foot-
controllers.
• Connect MIDI Thru to MIDI In of other devices you wish to receive the same data
from your MIDI controller which the QUAD TUBE 150M receives, such as MIDI-
controlled effects processors.
• Connect MIDI Out to MIDI In of other MIDI devices you wish to control from the
QUAD TUBE 150M front panel.
Sending and Receiving Libraries and Programs
The QUAD TUBE 150M can send or receive one or all of its User programs to another
QUAD TUBE 150M or a personal computer running an appropriate librarian or sequencing
program. This information is sent over MIDI as System Exclusive Data.
Connections for sending/receiving a library or program to/from another QUAD TUBE
150M:
• Connect MIDI Out from the QUAD TUBE 150M that is sending the data to MIDI In of
the QUAD TUBE 150M that is receiving.
Connections for sending a library or program to a personal computer:
• Connect the QUAD TUBE 150M's MIDI Out to MIDI In of the computer's MIDI
interface.
Connections for receiving a library or program from a personal computer:
• Connect the QUAD TUBE 150M's MIDI In to MIDI Out of the computer's MIDI
interface.
NOTE: Some librarian programs may require two-way communication with the QUAD
TUBE 150M. In this case it is necessary to connect both the QUAD TUBE 150M's
MIDI Out to the computer's MIDI In and the computer's MIDI Out to the QUAD TUBE
150M's MIDI In. When you do so, make sure MIDI THRU or the MIDI ECHO function is
turned OFF on the MIDI card/ad a
pter.
See page 45 to execute MIDI send & receive functions listed here.
Page 14 of 62
QUAD TUBE 150M OWNERS MANUAL
USING THE 4x4 MIDI PROGRAM CHANGER
The 4x4 is a universal MIDI controller included with the QUAD TUBE 150M combo amp. The
pedal features an ergonomic design for easy, consistent foot-switching in a compact
package, using four buttons that can each be programmed to send any MIDI Program
number to the QUAD TUBE 150M. There are 4 GROUPS to choose from, allowing a
different set of 4 MIDI Program numbers for each GROUP. The 4x4 sends MIDI Program
changes on any one of 16 MIDI Channels.
SET-UP
1) Before powering up the 4x4, connect one end of the 7 pin Phantom power MIDI cable
into the MIDI jack of the 4x4, and the other end into the MIDI IN jack of the QUAD
TUBE 150M.
2) Turn on the QUAD TUBE 150M. The 4x4 will display the number "8" on the screen,
then the MIDI channel number ("c0l" for channel 1), then the GROUP number ("b-1"
for GROUP 1, "b-2" for GROUP 2, etc.), then the program number ("01" for program
number 1).
3) Make sure that the 4x4 and the QUAD TUBE 150M are on the same MIDI Channel.
There are 16 MIDI Channels, and the factory default for the 4x4 and the QUAD TUBE
150M is Channel 1. Set the dip switches according to the instructions of the rear
panel to channel 1
4) Hit a few buttons on the 4x4 and the QUAD TUBE 150M should display the program
numbers as they change. If not, see "Checking the MIDI Channel," and "Setting the
MIDI Channel."
The 4x4 sends MIDI Program numbers from 1 to 128. There are four buttons and a four
position GROUP SELECT switch on the 4x4 to allow four quick program changes within any
GROUP for a total of 16 preselected programs of the 128 programs available in a MIDI
system. In setting up a rig for a performance, the 4x4 should be set up so that the switch
GROUPS do not have to be changed in the middle of a song.
CHANGING GROUPS
To change GROUPS, simply slide the GROUP SELECT SWITCH to a number (1-4). The
display will not change and no new MIDI messages will be sent until one of the buttons is
pressed.
PROGRAMMING THE BUTTONS
Programming the 4x4 (changing the MIDI Program number for a button) is about as easy as
it gets. The changes are automatically stored in the permanent memory of the 4x4, and will
not be lost when the power is turned off.
To program a button to send a different MIDI Program number, press and hold down that
button. The display will immediately show the number that is currently stored for that button ("
01" for program number 1), Keep holding the button down for a few seconds, and the display
will begin to scroll (" 02", " 03", etc. — after it has scrolled through 10 numbers, the scroll
speed will increase). When the display gets to the desired MIDI Program number, simply
release the button. The 4x4 will automatically store the new MIDI Program number in its
permanent memory and send out a MIDI Program change message of that new number.
Keep in mind that the programming is for the GROUP that is currently selected by the
GROUP switch.
CHECKING THE MIDI CHANNEL
To display the current MIDI Channel, simply press Buttons A & D at the same time. For
example, the display will show "c01" for MIDI Channel 1. Checking the MIDI Channel does
not cause the unit to send any MIDI messages. Pressing any button gets out of the MIDI
Channel display mode.
Page 15 of 62
QUAD TUBE 150M OWNERS MANUAL
SETTING THE MIDI CHANNEL
To send the MIDI Program changes on a different MIDI Channel, press and hold down
buttons A & D. The display will immediately show the current MIDI Channel ("c01", for
channel 1). Keep holding buttons A & D down for a few seconds, and the display will begin to
scroll ("c02", "c03", etc.). Release the buttons at the desired MIDI Channel. The 4x4
automatically stores the new MIDI Channel in its permanent memory.
RESETTING TO DEFAULT VALUES
To reset the unit to the default values that it originally came with, unplug power from the 7-pin
MIDI cable at the 4x4 pedal while the Quad Tube 150M is on.. Press and hold buttons A & D
down while reconnecting the MIDI cable. The display will flash r, S, t, for reset, instead of 8,
8, 8 when powered up. The default MIDI Channel is 1. The buttons have the following
defaults:
GRP#> 1 2 3 4
BUTTON PRGM PRGM PRGM PRGM
A 1 5 9 13
B 2 6 10 14
C 3 7 11 15
D 4 8 12 16
CHAPTER 4 TUTORIAL
This chapter will introduce you to the basics of using the QUAD TUBE 150M and lead you
step by step through its most important functions. Once you have completed the Tutorial, you
will be able to create and store your own programs, as well as use the factory Preset
programs, and use MIDI to control the QUAD TUBE 150M.
The QUAD TUBE 150M has more features than this Tutorial will touch on. The Reference
chapter gives detailed descriptions of every setting and will answer any questions you may
have left after completing the Tutorial.
Basics of the QUAD TUBE 150M
Programs
The QUAD TUBE 150M has two different kinds of settings that can be adjusted and stored:
those that affect individual sounds, and those that affect the whole QUAD TUBE 150M and
don't change when a program is changed. All of the settings that define an individual sound
are stored collectively as a program.
MIDI messages from a MIDI controller such as the ADA 4x4. Programs are edited in
Program Edit mode. Settings that affect the whole QUAD TUBE 150M are not stored as part
of a program, but as global
notably the MIDI functions in System Edit, are in effect all the time, regardless of what the
current program is.
settings and edited in System Edit mode. Global settings, most
Programs can be recalled from the front panel or by
NOTE: The Stereo Volume and Tuner Mute Controllers are both global Real Time
MIDI settings.
Page 16 of 62
QUAD TUBE 150M OWNERS MANUAL
In Program Edit mode, all of the settings (also called parameters) for that a program can be
adjusted. The QUAD TUBE 150M is in Program Edit mode when the PRGM EDIT button is
lit. (See page 45 in Chapter 5, REFERENCE, under PROGRAM EDIT MODE.)
In System Edit, parameters that affect the entire QUAD TUBE 150M (and are not stored as
part of a program) are adjusted. There is only one location for these settings, so they are not
stored and recalled as programs are. System Edit mode also contains utilities that allow
copying and swapping of programs between locations and other useful functions. The QUAD
TUBE 150M is in System Edit mode when the SYSTEM EDIT button is lit. (See page 71
inside Chapter 5, REFERENCE, see SYSTEM EDIT MODE.)
QUAD TUBE 150M DISPLAY
The QUAD TUBE 150M conveys messages, questions, and parameter information through
the display.
Play Mode
In Play mode, the display shows whether the QUAD TUBE 150M is running a User or Preset
program, the program bank and number, and its name.
Program Edit Mode
In Program Edit mode, the display shows one or more parameters in the currently selected
section along with their values. Arrows in the upper left and/or lower right comers indicate
that there are other parameter screens in that section. Parameter screens are explained on
page 27 in the Editing Basics discussion.
System Edit Mode
The System Edit mode display is essentially the same as the Program Edit mode display, but
