The TMC-1 has four connectors on the rear as follows
• 15 pin ‘D’ female: XMon connection including RS-422 or MIDI, Headphone, and
Microphone. The XMon communications are via MIDI or RS-422. We have tested this
with both 5m and 10m cables. If using the talkback Mic in the TMC-1, you may need
to screen this separately, as the XMon input is unbalanced.
• USB: Used for Power and if connected to MIDI on a DAW, this is used with MTC or HUI
for auto talkback and Timecode Display.
• ¼” Jack: Headphone Cue monitor connection to X-Mon via 15 pin ‘D’.
• 15 pin ‘D’ Male: GPIO in/out – Talkback 1 and 2 Enable/Selection, PFL/AFL enable,
H/W Mute output, LTC input, Play Input, Rec/Red light in/out.

The TMC-1 is designed as a desktop unit but may be mounted flush with the desktop. The
unit should be sited in any convenient position away from sources of moisture or excessive
heat. The TFT display brightness may be adjusted via the Setup menu to optimise viewing
under different lighting conditions.

TMC-1
Connecting to XMon
The 15 pin ‘D’ Female on the rear has the same pin connections as XMon. Use the DB15
M/M cable to connect. Where necessary extend the cable. To check connections see
Appendix
Power the TMC-1 via the USB cable supplied. The TMC-1 may be powered directly from the
USB power supply or connected directly to the DAW.
Tip:
It there is a long distance between the XMon and TMC-1, use RS-422
The TMC-1 will recognize and configure XMON to the last TMC-1 setting on power up. If the
XMON is not discovered, then No XMON will be displayed in the top right of the TFT Display.
Once good communications are established with the XMON, this will then be replaced as
selected in the Setup Menu. You can select to see the XMon software revision; the software
revision number of the XMon used to develop the TMC-1 was “Version 11”.

Factory Default:
We recommend that you start from the factory default setting. This sets all gains and Trims
at 0dB and selects the Main input and Output. To do this, you need to enter the advanced
menu – see appendix B: Selecting the Advanced menu (menu 24)
Having setup the unit to its default setting, you can then adjust each input trim as required
to achieve the required SPL level and trim the speaker outputs where necessary.

the [Page] key alone.
The Auto mode is controlled by transport tallies; two GPI inputs are provided Play and
Record and Hui via the USB port. If there is no Play tally output from your DAW you can use
either MTC via the USB connector or LTC via the GPIO connector as a play tally. You can
change the polarity of the GPIO inputs in the Setup menu. You can also program the User
key to act as a Play or record Start/Stop.
For each output there is an enable key (Blue = Enabled) and then Play Start, Play Stop,

Note: as XMon only has 8 channels Function key [9] will not select between speaker banks.
User Function Keys:
Not all users require the same functions, too many keys are confusing. The compromise that
we have made is to make most keys user programmable. User Keys 1-8 below the display
have two banks, you can use another key (eg. the [User] key) to select between banks. By
default the two banks are identical allowing you to change only a few keys in the second
bank.
User Keys 9, 10, 11 are not banked as their function is only displayed in the Select Page
screen.
You can also select the user keys by user or function with 5 user programmable selections,
which also include some of the setup options.
You can modify the user keys directly from the TMC-1 (You can lock this in the advanced
setup) but it is easier to use the TMC-1 configuration tool which is available for Mac or
Windows.
When programming the User keys you should remember that keys 2,3,4,7 are not available
on all screens, and that keys 1-8 are used for Speaker/Stem mute or solo.
The current user key functions are as follows

and an external talkback input on the TB/LB/UTIL Connector. The two inputs have individual
gain settings that can be adjusted from TMC-1. The two inputs are summed within the XMon
to provide a single Talkback Output available on the TB/LB/UTIL Connector.
The TMC-1 has two Talkback Switches (5 and 8) both of which enable the internal talkback
microphone. The switches also drive Talkback 1 and Talkback 2 GP Outputs.
The external talkback microphone is enabled by up to two GPI inputs. These both enable
the External talkback microphone and also drive Talkback 1 and Talkback 2 GP Outputs.
The two Talkback GP Outputs may be used to drive relays that switch the talkback output
destination.
The Cue Send page enables T/B 1 and T/B 2 to the 5 cue send outputs
Internal Talkback and Listen-back Latching [1] and [6]
When you depress and release the Talkback/Listen-back switches quickly, they latch so
that a second depression will release the Talkback/Listen-back. When you hold the
Talkback/Listen-back switches depressed for a longer time, the Talkback/Listen-back will
turn off when the key is released.
TMC-1 Internal/External Microphone Gain adjust
Whenever the T/B 1 switch [5] on the TMC-1 is depressed, the internal Talkback Microphone
Gain is displayed at the lower right of the TFT display. The gain may be adjusted by the
Encoder.
Whenever the T/B 2 switch [8] on the TMC-1 is depressed, the external Talkback
Microphone Gain is displayed at the lower right of the TFT display. The gain may be
adjusted by the Encoder.

Power
The TMC-1 uses about 400mA, this is within the 500mA maximum for a USB port. We
recommend that the TMC-1 is the only device connected to the port. If you are not using
the MTC or HUI functions, you can use a 5v USB power supply.
HUI Emulation
To use the HUI emulation, define the MIDI port as a HUI interface in the Workstation (DAW).
The HUI Play and Record tallies will then drive the automated switching. You can check the
interface by enabling the HUI positional display in the top line.
The Debug section includes a HUI Status display, if you find a key function that would be
useful to include in the TMC-1, please report its code and we will look into updating the
software.
MIDI Timecode
To use MTC, connect to a workstation and define it as a MIDI Port. MTC ¼ frame timecode
will enable the Play tally drive the automated switching. You can check the interface by
enabling the MTC positional display in the top line.
Firmware Updates
The USB Port is also used to update the TMC-1 firmware. Updates are posted on the TMC-1 –
Xmon or TMC-1-Penta product page:
http://www.colinbroad.com/cbsoft/tmc1/tmc1.html
http://www.colinbroad.com/cbsoft/tmc1/tmc1penta.html
You will find both a Mac and Windows version of “midiupd” on the same page which
should be used to send firmware updates to the TMC-1
Midiupd includes instructions, you can also find the TMC-1 programming guide on the web
site.

once finished
Recovery
In the case of power failure or other problems when updating the TMC-1 firmware.
1. Abort and exit from “midiupd”
2. Unplug the USB then reconnect whist depressing [Select] and [Ctrl]. The Software
Download screen will be displayed.
3. Restart “midiupd”. You will need to select the CBCore MIDI ports

XMon cannot be considered as a standalone device but as part of a monitor system
consisting of the XMon, Power amps and Speakers.
The main gain section of XMon uses digital gain control to provide a gain range of +31dB to
-95db. As can be seen on the chart below, to optimize the signal-to-noise ratio, it is
important that XMon is run at between 0dB and +10dB gain for normal levels.
