INTRODUCTION
Welcome to the TOA 900 Series
Module Guide!
In this guide, you'll find everything you need to take
advantage of the powerful flexibility of 900 Series
modular products — function descriptions; signal
flow and wiring diagrams; specifications; jumper
settings; application examples; and other useful
information.
Understanding the modules will give you the
freedom to configure custom systems FAST without
complicated modifications. And as your customers’
needs change, you can easily add more inputs or
new functions by simply changing or adding
modules.

MODULE SELECTION PAGE 3
MODULE SELECTION
Module Categories
There are three main module categories 1. Mic
2. Line
3. Special Function
Model Numbers
TOA assigns module model numbers using the following
convention: a-bbc, where "a" indicates the module
"Series", "bb" indicates the module "Function", "c"
indicates the module "Connector Type".
For example, with the M-11S module,
"M" indicates "Microphone" Series
"11" indicates "Mute Receive" Function
"S" indicates "Screw Terminal" Connector.
See the "Module Selection Chart" on page 5 for further
details.
Signal Levels
There are three general categories of signal levels in
audio.
1. Microphone (Mic) Level
• Typically 0.25 mV (-70 dBu) to 2.5 mV (-50 dBu)
• Examples include: microphones, wireless
microphone receivers
2. Line Level
• Typically from 100 mV (-18 dBu) to 7.75 V (+20 dBu)
• Examples include: AM/FM tuners, CD players,
cassette decks, computer sound cards, jukeboxes,
satellite receivers, signal processors, telephone page
outputs, wireless microphone receivers
3. Speaker Level
• Typically higher than 7.75 V (+20 dBu)
• Amplifier output for driving speakers
• TOA does not currently offer modules to accept
Speaker Level signals (external pad required).

Module Series
Notes:
• Connecting a Mic Level signal to a Line Input
module usually results in very low, barely
audible, output.
• Connecting a Line Level signal to a Mic Input
module usually results in distorted output.
• NEVER connect a Speaker Level signal to a Mic
or Line Input module - this will damage the
module.
• The type of module connector does not
necessarily indicate the input sensitivity. For
example, there are both Mic and Line Input
modules available with female XLR jacks.
Installation Notes
• Always turn the power OFF on the host unit
before installing or removing modules.
• Before installing each module, check the
supplied module installation sheet to determine
if any configuration is required. See Jumper
Settings on page 35 for a list of possible
configurations.
• Always secure each module to the host unit's
chassis with the supplied screws.

MUTING PAGE 7
MUTING
Muting Defined
Muting occurs when one signal source Overrides, or
“Mutes”, a second signal source. In other words, the
first source has Priority over the second source.
For example, a common requirement is for paging to
override a music source.
Module Edge Connector
Mute Buses
There are two main types of 900MK2 muting
modules - Mute-Receive and Mute-Send.
Both types have mute function circuitry that
connects to two common "Mute" buses, and one
common "Ground" bus when installed in an A900MK2 mixer/amplifier or M-900MK2 mixer/preamplifier. A "Bus" is simply an internal connection
from module-slot to module-slot. You can access
these buses via rear-panel screw terminals, labeled,
"MUTE 1", "MUTE 2" and "GND".
Mute-type modules connect to both mute buses by
default. You can disconnect the module's mute
function circuitry from each mute bus by cutting
jumper wires on the module. This allows you to
configure systems with multiple levels of priority.
Mute Function Activation
By default, Mute-Send modules activate both mute
buses and Mute-Receive modules respond to both
buses.
You can activate the mute bus(es) using either of two
methods:
1. Mute-Send
When input signal level to a Mute-Send module
exceeds a user-adjustable threshold, the module's
mute function circuitry activates the mute function
circuitry of all Mute-Receive modules connected to
the same bus. This is also referred to as "signalactivated muting" or "auto-muting".
2. Switch Activation
A switch closure between the "Mute (1 or 2)" and
"GND" screw terminals on the rear of the
mixer/amplifier will activate the mute function
circuitry of all Mute-Receive modules connected to
the same bus. This is also referred to as "manual
muting".

PAGE 16 LINE INPUT MODULES: LINE MATCHING
IMPEDANCE MATCHING
Most modern audio devices have LOW Impedance outputs
which are designed to drive HIGH Impedance inputs. This
results in Maximum Voltage Transfer - almost all of the
output's signal voltage is transferred to the input. This is also
referred to as a Bridged connection.
Impedance matching (output impedance to input impedance)
results in Maximum Power Transfer and causes
approximately 6 dB of signal voltage loss. This often exceeds
the source device's "minimum load impedance" specification
causing distortion or, at worst, damage to the source's output
circuitry.
Maximum Voltage Transfer occurs when input impedance
equals at least ten times the source device’s output
impedance.
For example, if the source's output impedance equals 600 Ω,
the input impedance of the next device should equal at least
6 kΩ or greater.
Tip! You can convert the input impedance of an “L” module to
10 kΩ by locating and cutting "R1" (680 Ω) on the module
PCB. This will result in approximately 6 dB of additional gain,
assuming the source’s output impedance is 600 Ω.

•Use For Adjacent Sources (less than 15 feet from the

•Remote Volume Control by connecting an external 10 kΩ,
linear-taper potentiometer to screw terminals #4 and #5.
•Tip! You can also connect a switch between screw terminals
#4 and #5 for remote on/off operation. Closing the switch
turns the module OFF, opening the switch turns the module
ON.
Note: Control line resistance greater than 200 Ω will prevent full
attenuation (200 Ω = 3821 ft. of #24 AWG wire).
•Tip! You can also use the U-21 as a stand-alone Remote
Volume control by cutting Jumper J2 to disconnect the
module's output from the mix bus. This function is useful in
original 900 Series mixer/amplifiers which did not have
built-in Remote Master Volume terminals or, as a second
Remote Master Volume for the A-903/6/12MK2
mixer/amplifiers, the AX-1000A auto-mixer or the M900MK2 mixer/pre-amplifier. Connect the module input to

APPLICATIONS
Paging Over a Music Source
1. Connect the Telephone Page output to a B-41S
(Balanced Line Input with Mute-Send) module or,
for Microphone Paging, use an M-41S (Microphone
Input with Mute-Send) module.
2. Connect the Music Source to a U-13R (Unbalanced
Line Input with Mute-Receive) module.
3. Adjust the mute threshold as necessary with the
Sensitivity control (located on the mute-send
module's circuit board). If the paging audio falls
below the mute threshold for greater than
approximately two seconds, the music will resume.
Since mute-type modules connect to both Mute Bus #1
and #2 by default, no jumper configuration is required.
Telephone Paging and Music-On-Hold
1. Connect the Telephone Page output to a B-41S
(Balanced Line Input with Mute-Send) module.
2. Connect the Music Source to a T-12S (Unbalanced
Line Input with Music-On-Hold Output) module's
input.
3. Connect the T-12S module's output to the
telephone system's Music-On-Hold input.
4. Adjust the output signal level with the T-12S front
panel Output Gain control.
Since mute-type modules connect to both Mute Bus #1
and #2 by default, no jumper configuration is required.
Banquet Room Sound System
Banquet room sound systems usually include a podium
microphone and a music source. Since there will be a
variety of presenters, the signal level present at the
microphone will vary. The music volume level will also
need to be remote controlled from the podium.
Because the microphone level will not be continuous,
Switch Closure Muting will be necessary to ensure that
the music remains off until after the presentation.
1. Connect the Podium Microphone to an M-61S
(Microphone Input with Compressor).
2. Connect the Music Source output to a U-21S
(Unbalanced Input with Remote Volume Control).
3. Connect a 10 kΩ linear-taper potentiometer to
screw terminals 4 and 5 of the U-21S.
4. Connect a switch (normally-open) between screw
terminals 4 and 5 of the U-21S.
(pins #4 and 5, U-21S)
5. Set the M-61S Threshold control according to the
highest potential signal at the microphone.
Closing the switch mutes the music, opening the
switch allows the music to resume.
APPLICATIONS PAGE 31
School Gymnasium Sound System
School gymnasium sound systems often have similar
requirements as the banquet room system plus
telephone paging which must override both the podium
microphone and the music.
1. Connect the Telephone Page output to a B-41S
(Balanced Line Input with Mute-Send) module.
2. Connect the Podium Microphone to an M-11S
(Microphone Input with Mute-Receive) after cutting
Jumpers J4 and J5. This configures the module for
Normally-On mute activation mode on Mute Bus #1
only.
3. Connect a switch (normally-open) between the
screw terminals Mute #2 and Ground on the
amplifier's rear panel.
4. Connect the Music Source output to a U-13R
(Unbalanced Line Input with Mute-Receive)
module.
Pressing the podium mic's "press-to-talk" switch
activates Mute Bus #2 and mutes the music. The
telephone page activates both Mute Bus #1 and #2,
muting both the podium mic and the music source.
FREQUENTLY ASKED QUESTIONS
General
1 Which module should I use for a microphone?
For a standard low impedance microphone, use the ML-11T or, for a high impedance microphone (uncommon),
use the M-03. See pages 9-12 for details on other available microphone modules.
2 Which module should I use for a wireless microphone receiver?
If the wireless receiver has a line-level output, use the B-01 or, for a mic level output, use the ML-11T. Both
types give you the flexibility to locate the receiver remote from the module, if necessary. See pages 9-23 for
details on other available microphone and line input modules.
3 Which module should I use for an AM/FM tuner, cassette deck, CD player, computer sound card, jukebox,
mixer or satellite receiver?
If the source will be less than 15 feet from the module, use the U-03R or, to respond to mute activation, the U13R. Both modules have dual RCA jacks for quick connection of stereo sources and high/low-cut filters for EQ
adjustment. If the music source is further than 15 feet, use the B-01 or the B-11, which accept balanced lines
and offer transformer isolation. See pages 13-23 for details on other available line input modules.
4 Which modules should I use for telephone or microphone paging with priority over a music source?
Use the B-41 for the telephone paging input or the M-41 for microphone paging. If the music source is less than
15 feet, use the U-13. If the music source is further than 15 feet, use the B-11, which accepts balanced lines
and offers transformer isolation.
5 Which module should I use for Music-On-Hold (MOH)?
Use the T-12 module which has an unbalanced line input for the MOH source plus a balanced, transformerisolated, adjustable output to connect to the telephone system's MOH input. The MOH signal routes to both the
internal mix bus and the MOH output. The mix bus input also responds to mute bus activation without
interrupting the MOH output. See page 25 for more information.
6 What type of potentiometer do I need for a Remote Volume Control module?
Use a commonly available, 10 kΩ, linear-taper potentiometer for the B-21, M-21, or U-21 Remote Volume
Control modules. Also, use the same type for the rear-panel Remote Master Volume screw terminals on A903MK2, A-906MK2 and A-912MK2 mixer/amplifiers, or the M-900MK2 mixer/pre-amplifier.

FREQUENTLY ASKED QUESTIONS (continued)
General
7 How do I use one of the 900 Series processor modules?
When using one of the processor modules such as the E-03R, E-04R, E-05R, E-06R with an A-900MK2, insert
the module in an empty module slot. Then run a cable from the pre- amp out jack located on the rear of the
A-900MK2 to the input jack of the processor module. Next run a cable from the output jack of the module to the
power amp in jack on the rear of the amp. This will route all audio signal through the processor module before it
reaches the power amp section of the unit.
When using a processor module with an M-900MK2 mixer and P-900MK2 power amp, the processor module
can be inserted in an empty slot on the M-900MK2. Connect a cable from the aux out jack on the M-900MK2 to
the input of the processor module. Then connect a cable from the output jack of the processor module to the
input of the P-900MK2 power amp.
Another way of doing this would be to insert the processor module in the module slot of the P-900MK2. Connect
a cable from the output of the mixer to the input of the processor module. Then connect a cable from the output
of the module to the screw terminal input of the P-900MK2 power amp.
8 What is the proper wiring for the screw terminal type input modules?
Pin 1: Earth. Pin 2: Common. Pin 3: Hot. When wiring an unbalanced source to a balanced input module:
Connect the source (+) output to Pin 3 Hot. Connect the source (-) or shield output to Pin 2 Common.
9 What’s the difference between the “L” Series and “B” Series modules?
“B” Series modules are balanced, line level, high impedance inputs.
“L” Series modules are balanced, line level, low impedance inputs.
Most modern audio equipment provide low impedance outputs which are designed to drive high impedance
inputs. Maximum voltage transfer occurs when the input impedance is at least ten times the source output
impedance. Almost all of the output signal voltage is transferred to the input.
Impedance matching (output impedance to input impedance) results in maximum power transfer and causes
approximately -6dB of signal voltage loss. This can often exceed a source device’s minimum output load
impedance specification. In most cases, use B Series instead of L Series modules.
10 Which modules are for “mute send”?
M-41S for microphone level input. B-41S, L-41S for balanced line level input. U-43R, U-43S for unbalanced
line level input. ML-11T for microphone or line level input (selectable). S-20S is a digital message repeater
module with mute send select-ability.
11 Which modules are for “mute receive”?
M-11S for microphone level input. B-11S for balanced line level input. L-11 for balanced or unbalanced line
level input, low impedance, line matching. ML-11T for microphone or line level input (selectable). U-11R,
U-11S, U-12S & U-13R can be used for unbalanced line level input. U-14R for unbalanced dual input priority
(Jukebox input mutes BGM input), both are muted when the mute receive jumper is set.
Troubleshooting
12 Why won't the M-11 (Microphone Input with Mute-Receive) pass signal?
The M-11 will not pass signal "out-of-the-box". Cut jumpers to select the mute response mode: Normally-Off or
Normally-On. See page 35, Jumper Settings, for more information.
13 Why won't my paging source override my music source?
First, verify that the paging source is connected to a Mute-Send module and the music source is connected to a
Mute-Receive module. Next, verify that the module jumpers are configured for Mute Bus #1 or Mute Bus #2 (or
both). Test the Mute-Receive module's mute function by placing a jumper between Mute Bus #1 (or #2) and
Ground terminals. Last, adjust the Mute-Send module's "Sensitivity" control to lower the mute activation
threshold. The Mute-Send module activates the mute function based on input signal level exceeding this
threshold.
14 Why isn't my condenser microphone working with an M Series module?
Verify that Jumper "J1" on the M Series module circuit board is intact and secure the module to the chassis
with the supplied screws.
15 Why is my signal level low with an L Series module?
Removing resistor R1 (680 Ω) on the module's circuit board will provide approximately 6 dB additional gain by
converting the module's input impedance to 10 kΩ. See page 16, "Impedance Matching".
