Install and Connect the M-2
1. Install the M-2 in the equipment rack using at least two rack screws. If only two
screws are used they must be installed in the bottom holes of the rack ears to pre-
vent undue stress on the front panel and possible bending.
2. Connect the microphone to the XLR female microphone input on the rear panel.
3. Connect either line level analog out or AES digital out XLR connector to your
desired signal path.
4. When using the M-2 GUI software connect rear panel Ethernet RJ--45 jack as ap-
propriate for your intended use:
a) a direct connection to PC uses crossover CAT5 cable;
b) a connection to your LAN requires a straight through CAT5 cable
between the M-2 and the Ethernet switch or HUB.

Installing GUI Software
The M-2 must be controlled using the included Microsoft Windows-based PC GUI
software. To install the software insert the M-2 software CD into a Windows XP/2000
computer’s CD drive and follow the steps below to install the software. If the software
installation does not automatically start when the CD is inserted into the drive, you can
start the installation manually by:
- Clicking Start
- Then click Run
- Then click Browse
- Browse the “My Computer” device tree to locate the CDROM device and
then double click it.
- When the contents of the CDROM drive appear in the window, locate the
autorun.inf or M2GUISETUP_X_X_X.EXE le on the CDROM and double
click it.
- Follow the on screen instructions to complete the GUI installation.
Configuring the M-2 IP Address*
Once the GUI has been installed on the host PC it’s time to congure it and the M-2
so that they can communicate with each other. This requires conguration for both the
M-2 and the remote GUI so that they agree on the networking parameters.
PLEASE NOTE: As shipped from the factory, the M-2 is pre-programmed
with an IP address of 192.168.1.192, a subnet of 255.255.255.0, and a gateway of
192.168.1.1. If these settings will work in your application, you DO NOT need to
change the M-2’s IP address. Proceed to following section, Conguring the GUI.
Before starting the conguration procedure, please
locate and carefully make a note of the M-2’s 12-digit
MAC Address which is located on a label either on the
top cover or the rear panel.
Note that if the MAC address is not entered care-
fully and correctly in the following steps, the M-2’s IP
address will not be changed!
Start the M-2 GUI software. Then right click on the
control area of the GUI and select Hardware/Assign IP
Address. The window on the right will appear:
*The M-2 does not support DHCP (Dynamic Host Congura-
tion Protocol) and therefore it requires a static TCP/IP address on
the Network it is connected to. Its presence on the network will not
interfere with DHCP addressing of other network connected devices
as long as the IP address that is congured for the M-2 does not
conict with the address of any other device on the network. Please
consult your friendly IT manager if necessary.

M-2 / Oct 2009

Next, carefully enter your M-2’s MAC address in the MAC Address eld. The MAC
address must be carefully entered because the GUI will “send” the IP address informa-
tion to the device that owns the MAC address that was entered in this step. If the MAC
address is incorrect, the M-2 will never “hear” it.
Next, enter a pet name for your M-2, like AirStudio1, etc.
Then, enter the IP address that you wish the M-2 to have, noting that this address
must be unique if the M-2 will be communicating over your network.
Next enter the desired Subnet Mask and Gate-
way IP addresses.
Once this is done, click the “Start” button at
the bottom of the IP address conguration box.
A message similar to the one on the right should
appear:
Click OK. Remove power to the M-2 for a
few seconds and then reapply it.
As the M-2 is booting up, the “Requests” number in the IP Assignment window
should increment to something other than zero (please see the bottom of the image on
the right). When this occurs the M-2 has received and acknowledged its new IP address
and is now ready for use on your network. Click the X in the upper right corner of the
IP Assignment window to dismiss the dialog.

M-2 / Oct 2009

Location of “Devices” button
Configuring the GUI
Now that the M-2 has its own TCP/IP identity, we must congure the GUI so that it
can talk to the M-2. This is done by adding “devices” to the list of M-2’s that the GUI
knows about. To do this, locate and click on the “Devices” button located along the right
side of the GUI.
When this is done, the following window will pop up:
Next, click the “Add” button and a new
dialog box will appear. This is how new de-
vices are added or the conguration of existing
devices modied.
First, enter the same pet name that you used when you assigned the IP address to the M-2.
The above dialog shows us adding a new device called “WNYC_News_2_M2_07.”
Then enter the IP address that you congured the M-2 for in the previous steps. Note that
it is always best to completely delete any existing data in the IP Address box and then enter
the complete address from scratch.

M-2 / Oct 2009

After this is done you may click “OK” on the Edit Device box. Then, in the Devices
Dialog box highlight (single left click) the
M-2 device that you just added (shown
highlighted in the image on the left) and
click on “Select.”
This step tells the GUI specically which
M-2 you want to connect to.
Next, click on the Online/Ofine button just to the left of the Status indicator, unless
the button’s green indicator is already lit.
In the Status window you may see the message “Trying” as the GUI is handshaking
with the M-2. Once the handshake is complete and communication protocols are locked
in the Status message should revert to “Online.” The device’s name will show up in the
Devices display.
If for some reason the GUI cannot connect with the M-2, the “Trying” status message
will remain and will occasionally blink as the GUI retries the establishment of a connec-
tion. Under these circumstances the conguration of the GUI and M-2 should be carefully
examined to ensure that the destination TCP/IP address is consistent between the two.
Once these steps are complete you are now ready to use the M-2 from anywhere in
the world through its advanced Graphical User Interface.

GENERAL INFORMATION
General Information
Introduction
The Wheatstone M-2 Digital Dual Voice Processor is a uniquely exible and easy-
to-use multiband voice processor designed for professional audio applications. It offers
user presets, security, networkability, an all digital and fanless DSP-based framework,
and easy to set up parameters. The unit occupies one 19” wide rack space (height 1 3/4”),
and is 12” deep (not including connectors).
All adjustments of the M-2’s sound are controlled from the remote GUI, enabling
remote control of all parameters. The use of presets allows voice talent to have their own
sound simply at the press of a button. In fact, from one GUI it is possible to control an
entire facility equipped with M-2’s, making multiple Microphone Processor management
easy and straightforward.
The M-2’s hardware includes two channels equipped with very high quality, low-noise
microphone preampliers, four bands of parametric EQ, and Vorsis-designed processing
tools such as de-essers, compressors, and expanders. The unit comes loaded with factory
designed presets, and thanks to the exibility of the software-based GUI designing your
own sound is quite easy.
The electrical specications of the M-2’s microphone preamplier approach the theo-
retically perfect. Noise within the audio band nudges the theoretical minimum, limited
only by the thermal (Johnson) noise of the precision resistors* used. Frequency response
is ruler at beyond the extremes of human hearing, and unwanted signal distortions such
as THD, IMD, and TIM are vanishingly low.
Static waveform delity is virtually perfect, affected only by the input high pass and
low pass lters, the phase scrambler when it is in circuit, and any equalization being used.
XLR and CAT5 connectors, which are located on the rear of chassis, make installa-
tion very simple.
*Thermal noise is intrinsic to all resistors and is not a sign of poor design or manufacture, al‑
though certain types of resistors may have excess noise.

GENERAL INFORMATION
Pre-Installation Notes
• The M-2 should be mounted in a well grounded equipment rack using at least
two, and preferably four, rack screws. When only two screws are utilized they
must be installed in the two bottom holes in the M-2 front panel rack ears in
order to prevent undue twisting and distortion of the front panel.
• If the M-2 is installed in a rack containing heat generating equipment, particu-
larly when it is installed above such equipment, one rack unit (1 3/4”) blank or
ventilated rack panels should be installed above and below the M-2 in order to
aid natural convection cooling.
• The M-2 should be connected to a source of clean AC power. If local power has
a history of being unstable, it is wise to incorporate an Uninterruptible Power
Source (UPS) in the AC power feed to the M-2*.
• In facilities with a history of damage or surges from lightning or other sources,
it is wise to incorporate a good quality AC line surge suppressor in the M-2
power feed*.
• Audio connections to the microphone inputs should be balanced and made with
a high quality shielded microphone grade cable. The cable shield should be
terminated at both ends of the cable to the XLR connector’s Pin #1. We do not
recommend the use of unbalanced connections at the M-2 inputs.
• As far as signal input polarity is concerned, the XLR Pin #2 is “hot” and the
M-2 does not invert the phase of the audio unless the Invert option has been
selected. (The exception to the above statement is when the Phase Scrambler
is used, which will result in frequency dependent phase shift which causes the
output signal’s phase to be inverted relative to the input signal at certain audio
frequencies.)
*As with all computer or microcomputer based digital equipment the M‑2 requires clean
and surge‑free AC power for proper operation. Otherwise unpredictable and hard to identify
issues may arise with its operation and, in the extreme case, even equipment damage or cor‑
ruption of data.

GENERAL INFORMATION
Rear Panel Connections
All audio input and output, control, Ethernet, and power supply connections are made
via various connectors conveniently mounted on the M-2’s rear panel. Six XLR con-
nectors are provided: two microphone inputs, two analog and two digital outputs. Five
RJ-45 connectors are also provided; two duplicate the signals appearing at the Channel
One and Channel Two AES output XLR connectors. The others serve as interfaces for
the control and Ethernet connections. The DB-9 connector provides eight GPI inputs
for the most used presets. The pinout drawings on pages 1 -9 through 1-11 summarize
all wiring connections.
Microphone Inputs
The M-2 possesses TWO microphone level inputs (-50dBu nominal) fed from the
female XLR connector to the internal microphone preampliers. The microphone pream-
plier has digitally controlled gain, up to a maximum of 70dB, and displays remarkably
high performance and sonic accuracy. Phantom power is available.

M-2 / Oct 2009
GENERAL INFORMATION
Optional GP-4S Mic Control Panel
The optional GP-4S panels connect to the M-2 using a standard straight
through CAT5 Ethernet cable of any reasonable length. This panel has “ON,”
“OFF,” and “COUGH” switches for remote control
of the microphone inputs. The “TB” (talkback) but-
ton is designed to interact with Wheatstone audio
consoles and has no function in the M-2. The “ON”
and “OFF” buttons are LED illuminated. These
panels can be mounted directly into a furniture
surface or a turret if desired.
To Turn Microphones ON & OFF from a Remote Location
REMOTE ON — When taken low (connected to Digital Ground) activates the
ON TALLY and simultaneously unmutes the M-2 audio output for that channel. You
must provide a momentary closure between Remote On (Pin 7) and Digital Ground
(Pin 1) to latch the microphone audio ON. A user-supplied momentary contact switch
or the optional GP-4S panel is required.
REMOTE OFF — When taken low (connected to Digital Ground) activates the
OFF TALLY and simultaneously mutes the M-2 audio output for that channel. You
must provide a momentary closure between Remote Off (Pin 6) and Digital Ground
(Pin 1) to latch the microphone audio OFF. A user-supplied momentary contact switch
or the optional GP-4S panel is required.
COUGH — When taken low (connected to Digital Ground) temporarily mutes
the microphone for the selected M-2 channel. You must provide a momentary clo-
sure between Cough (Pin 2) and Digital Ground (Pin 1) to temporarily mute the
microphone. This is a non-latching mode so the microphone will unmute as soon
as the switch is released. A user-supplied momentary contact switch or the optional
GP-4S panel is required.
On and Off Tallies
ON TALLY — A continuous closure (via open collector) exist between On Tally
(Pin 5) and Digital Ground (Pin 1) whenever the microphone audio is unmuted. This
allows the microphone ON function to also control an on-air light or other “micro-
phone on” indicator at a remote location.
OFF TALLY — A continuous closure (via open collector) exists between
Off Tally (Pin 4) and Digital Ground (Pin 1) whenever the microphone audio is
muted. This allows the microphone OFF function to also control a “microphone off”
indicator at a remote location.
The ON and OFF tallies can be used to control externally powered tally lights
or other functions requiring a continuous closure to function. External tally lights
(such as LEDs) can be powered from the tally output by connecting the external
LED anode to +5V Digital (Pin 8)*and the external LED cathode to the On Tally
port (Pin 5) or Off Tally port (Pin 4).
* An appropriate current limiting resistor must be used so that current drawn from Pin 8
does not exceed 15 milliamps.

GENERAL INFORMATION
General Purpose Interface
The General Purpose Input (GPI) control port on the M-2 works a bit differently
than in other Wheatstone processors. In the M-2 the eight GPI inputs operate as follows:
- GPI ports 1 through 4 are hard coded to select presets for M-2 Channel One.
- GPI ports 5 through 8 are hard coded to select presets for Channel Two.
The eight separate General Purpose Inputs share a common return. The rear panel
connector is a female DB-9 connector with the following pin assignments. Note that all
pins are isolated from M-2 internal circuitry!
GPI—DB-9
Pin 1 – GPI COM (-)
Pin 6 – GPI 1 IN (+)
Pin 2 – GPI 2 IN (+)
Pin 7 – GPI 3 IN (+)
Pin 3 – GPI 4 IN (+)
Pin 8 – GPI 5 IN (+)
Pin 4 – GPI 6 IN (+)
Pin 9 – GPI 7 IN (+)
Pin 5 – GPI 8 IN (+)
The GPI input circuits are optoisolated by devices having an input/output isolation
of 1,500VAC. These inputs are expected to work very well in high RF environments
and will not cause ground loop issues when connected to external equipment.
Each of the GPI inputs is current limited by a 475 ohm resistance located inside
the GPI control circuitry. The LED device inside the optoisolators is rated at a maximum
forward current of 50mA and a normal operating current of 5mA.
Before connecting external circuitry to the GPI inputs you should rst ascertain whether
it will be necessary to utilize additional outboard series resistance in your application!
The following table will serve as a convenient reference to determine if an external
resistance is required in your application and if so, what value that resistance should be.
Note that in all applications up to and including 48VDC a one-half watt resistor power
rating is sufcient.
Applied Voltage to GPI External Resistance
3.3 VDC None
5.0 VDC 330 Ohms
6.0 VDC 470 Ohms
7.5 VDC 820 Ohms
10 VDC 1.3 kOhms
12 VDC 1.8 kOhms
15 VDC 2.4 kOhms
24 VDC 3.9 kOhms
30 VDC 5.1 kOhms
48 VDC 9.1 kOhms

M-2 / Oct 2009
GENERAL INFORMATION
Ethernet Interface
The rear panel RJ-45 connector that is assigned to the Ethernet communication
function uses a standard 10/100BaseT interface. It employs both UDP and TCP/
IP protocols to communicate with the remote GUI software running on a host PC
and utilizes common ports to communicate with the M-2.
Ethernet—RJ-45
Pin 1 – TXD +
Pin 2 – TXD -
Pin 3 – RXD +
Pin 4 – N/C
Pin 5 – N/C
Pin 6 – RXD -
Pin 7 – N/C
Pin 8 – N/C
When using the M-2 with a nearby computer and when no local area network
is available, you must use a standard Ethernet crossover cable to interconnect the
computer and the M-2.
When using the M-2 with a remotely connected computer or when it is intercon-
nected to the remote computer via a LAN you must use a standard straight through
Ethernet cable.
Please see the drawing below for the wiring for both straight through and
crossover cables.
In each case the color code for the GUI PC end of the cable is as follows:
1 – White w/Orange tracer
2 – Solid Orange
3 – White w/Green tracer
4 – Solid Blue
5 – White w/Blue tracer
6 – Solid Green
7 – White w/Brown tracer
8 – Solid Brown
