For the first time or after Major Software Update
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
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.
Note: TMC-1 Penta Reconfigure the TMC-1-Penta from the TMC1-Penta2 program after a

Protected/Calibrated Settings
The gain structure of the TMC-1 monitor control is determined by a number of protected
calibration menu's and settings. The only absolute setting is Gain, SPL and Dolby level are
also determined by the speakers and their amplifiers.
To remove the protection and enable calibration
1) Depress [select] and [Page] to access the “Select Page”
2) Select [Setup]
3) Calibration enable is in the Advanced Setup, to access depress [Select] and [->]
keys to access Adv Menu 01.
4) Depress the [->] key to access Adv Menu 02:- Calibration Lock
) Use the [^] and [v] keys to select Unlock All
6) Use the [Page] to exit setup, the TFT display will now show “Calibration” in the top
Right.

Input and output trims
The TMC-1 has programmable input and output gain trims, these may be set in Calibration
Mode which is enabled in the advanced menu. The Input and output gain trims can be
viewed on the "Levels" pages, to access depress [select] and [Page] to access the “Select
Page” the depress the [Levels] key. Use the [->] key to step through the pages.
Input Trim:
Each input has a -10db to +20dB input trim in 1dB steps, the Input trim is before the meters
and is used to match levels between different inputs. For example the Dolby RMU default
output level is -10dB. Normally we set the Input trim for the RMU at +10dB
1. Enable Calibration as above
2. Select the Meters page
3. Enable the input Selection [I/P Sel], this is a user defined key
4. Disable [Sum]
. Depress and hold the selected input, a Red Box in the lower right will display the
Input Trim
6. Adjust as required whilst holding selected input key depressed
7. Repeat as required for all inputs
8. Disable Calibration
Speaker Trim:
Each speaker output has a +/-4dB trim in 0. dB steps. The output trim is after the meters and
used for individual speaker calibration. To maximise signal to noise the range is limited,
where necessary attenuate the speaker amplifier input or use a input pad.
The TMC-1-penta provides two extra global menu settings as follows
•"Adv menu 20 - Digital Headroom" Output attenuation on all outputs
•"Adv Menu 22 - Analogue Output for 0dBFS" on all Analogue outputs
To set the speaker trim, select the Meters page then enable speaker Solo using the [Solo]
key, by default this is the [Ctrl/Spk.Solo] key.
1. Enable Calibration

TMC-1 Reference Manual
14 September 2018  CB Electronics 9 Version 6.0
2. Connect input to Pink Noise at reference level (-20dBFS 0dBm nominal)
3. Enable the “Solo” page using the [Solo] key (Note Solo is a user function), Select the
required output and speaker, on the Penta version you can step through the
speaker banks using the [Solo] key.
4. Solo the individual speaker, hold the speaker key depressed, a Red Box in lower
right will display the speaker trim
. Adjust as required whilst holding speaker key depressed.
6. Repeat as required for all speakers
7. Disable Calibration

TMC-1v Software for Mac or Windows may also be used adjust the input and output trims,
The password to enable calibration is "1984" (Big Brother is watching). You can save and
recall the calibration using TMC-1v .
The Number of speakers in each speaker Set can be defined and the speaker set selected.
Selecting a speaker will also solo the speaker when Calibrate is illuminated Where
appropriate the Digital headroom and Analog Level for 0dBFS will also be displayed.
The Solo Defeat key will remove any speaker solo.
It is recommended that the settings are saved to a file after Calibration for later recall.

1. Enable Calibration
2. Select the Meters or Input/Output page
3. Hold the [7.1] or [ .1] User key depressed, a Green Box in the lower right will
display the 7.1 or .1 trim
4. Adjust as required whilst holding [7.1] or [ .1] Depressed

Atmos, 7.1 and .1 calibrations
The setup procedure is as follows:
1) Setup the individual speaker trims in Atmos(immersive) mode
2) Select 7.1 is selected and adjust the 7.1 global surround trim until the surround level is
correct.
3) Select .1 or .1 DMix and adjust the 7.1 global surround trim until the surround level is
correct.

Note. the 5.1 and 7.1 calibration is very important when multiple speakers are
used for each surround channel.
Cal A/B Trim:
The factory reset value for Cal A is 8 and Cal B is 80. However, these values can be
adjusted when calibration is enabled.
1. Enable Calibration Mode
2. Whilst in the Advanced Setup, find “SPL @ 0dB Gain” Menu and set as close as
possible (2dB Steps)
3. Hold [Cal A] or [Cal B] depressed.
4. Adjust as required
. Disable calibration

The TMC-1 has 3 level display formats, SPL, Gain and Dolby, only Gain is absolute, SPL and
Dolby level are relative and calibrated by the user. The object of the calibration is to adjust
the output and speaker amplifier gain so that the monitor gain at the required listening
level is as close to 0dB as possible.
1) Decide on the listening level – for Film Dolby specify a SPL of 8 dBA.
2) Adv. Menu 2 - Enable Calibration mode on the TMC-1 (Unlock All)
3) Adv Menu 3 – Set the SPL Level Required +/-1dB
4) Menu 14 – Set the Display mode to dB
) TMC-1-Penta Only – Adv menu 22 – Set the Line level of 0dBFS
6) Exit menu and enable Speaker Solo, whilst holding the speaker key depressed adjust
the trim to 0dB
7) Select a Pink Noise Source to all channels and set up a SPL meter
8) Adjust the amplifier gain so that when the TMC-1 the gain display is approximately
0dB for the required SPL level. Switch to SPL display mode and use the TMC-1
speaker trim to make fine adjustments.
9) Repeat for each Speaker
Why is there no overall output level adjustment for the speaker sets?
In general amplifiers have too much gain, turning down the output on both analogue
and digital monitor systems would cause a reduction in the dynamic range, as this
attenuates the signal but not the noise. The optimum solution is to turn down the signal
at the input of the power amp, this will attenuate both the signal and any noise from the
monitor system. Where this is not possible use input pads on the input of the power amp
as detailed below.
