A-Mon Headphone Monitoring

I received an e-mail this morning from Paula Fairfield (Sound Designer on Game of Thrones) asking about headphone monitoring on her PD-3-AMon bundle. Paula is now now working in VR and headphone monitoring a big deal!

Paula's mail made made me think more deeply about this - with the existing software there are 2 solutions

1) Connect the Headphones to the Mini L/S output - I have customers doing this.

2) Use the Headphone Jack on the TMC-1 which is connected to the Headphone Cue send and "Link" the H/P Cue to the stereo down mix on the Cue Sends page

The main advantage of option 2 is that no extra cables are required, as it uses the existing connections between the TMC-1 and A-Mon complete with a headphone socket on the TMC-1/PD-3/TMC-1-S6.

The main problem with option 2 is that the Dim, Mute keys and Gain control do not control the Headphone Cue Output! You must use the [H/P] user key as a Mute key , and hold the [H/P]  user key depressed to adjust the H/P cue gain - not an optimal solution.

I have now updated the TMC-1-AMon software that simplifies option 2 by automating it within a single [Phones] user key that performs the following actions

[Phones] On

  1. Display "Phones" as the speaker set
  2. Set the Headphone Cue input to the Stereo Downmix
  3. Mute the Main, Alt and Mini Speaker sets
  4. Connect the Dim, Mute and Gain controls to the Headphone Cue Output.

[Phones] Off or select a Speaker Set

  1. Display the current speaker set 
  2. Restore the Headphone Cue input selection and Headphone cue gain to their previous setting
  3. Enable the selected speaker set
  4. Connect the Dim, Mute and Gain controls to the selected speaker set
This update will be available in the next release of TMC-1-AMon software, if you wish to use it before email me for a beta version of the software.

DADman, Mom, Eucon and TMC-1-Penta

I am often asked questions about the differences between these different controllers all of which can control the Avid MTRX, DAD AX32 or the NTP Penta. Can they can work together and what are their requirements?

Avid MTRX, DAD AX32 or the NTP Penta

Functionally very similar these units provide digital and analog i/o, digital patch and digital summing. In the description below I will talk about the DAD to refer to all these units. 


DADman is a software system for controlling signal gain, routing and summing (requires the Gain/Sum option) within the DAD. DADman requires a Windows or Mac computer to run and can be remote controlled from the Avid S6 via Eucon and/or by the MOM using a NTP protocol. The DADman software also provides metering.


Software used by the S6 to control DADman, Then S6 includes a level control and talkback key. A touch screen can be used to control other functions.


The MOM hardware Remote is connected to the DADman software via Ethernet. The MOM has 10 user programmable switches and LED's, a single knob,  the current gain is indicated by a ring of LED's around the knob.  A Layer switch is provided to select up to 4 layers indicated by a LED.  The function the switches and knob are defined for each layer within the DADman program.

iPad MOM App

Available from the apple App Store the MOM app emulates the MOM and has the advantage that the switches may be labeled by the user.

Minimum Mom-DADman system


The TMC-1-Penta connects directly to the DAD. It does not require DADman to operate however DADman may be used to route other signals within the DAD.

The TMC-1-Penta I/O connections are defined on a windows or Mac computer using TMC1-Penta4 software and saved by the TMC-1-Penta.

The TMC-1 has 18 switches and one knob most of which are user programmable. It has a 4.3" TFT display that is used to indicate the current signal source, level and speaker set and 8 or 12 channel metering. The display also indicates the functions of the user keys and knob..

Minimum TMC-1-Penta System (A Mac/Win PC is required for setup only)

TMC-1 with DADman


I am biased! I found the setup easier using the TMC-1-Penta software, once the inputs and outputs are defined the routing is configured by the TMC-1 software. You can define more esoteric systems using the DADman software, but as yet I have not found a user who needed more that the TMC-1-Penta can provide.

Preset or Scene - Whats in a name?


Whilst checking and updating the TMC-1-DMon for the latest version of the D-Mon software I found that I had labeled two user definable keys as 'Preset', Not Good!

'Scene' seems to be used more and more  to describe setup presets, I have replaced the new TMC-1 'Preset' described in recent posts with 'Scene' and replaced the 'Preset' for the  D-Mon  with 'S.Preset'.


Whilst making the updates I added D-Mon Studio Preset to the TMC-1 Scene so that when changing the studio setup it is also possible to change the D-Mon Studio Preset. Please let me know if it is necessary to include Session snapshots?

TMC-1 and Yamaha MMP1

This week I have been interfacing the TMC-1 with the Yamaha MMP1. We have been waiting for a MMP1 since it was announced last year, a loan unit finally arrived last week . Before starting we had to buy a I-Pad (we are Android users and our OSC software runs on both), this arrived two days ago since then I have been writing code.

TMC-1 Yamaha MMP1

You can run the TMC-1 alone or with the MMP1 editor and/or remote. For testing I am running the TMC-1 with the Yamaha Editor and I-Pad App. The TMC-1 can activate all the controls on the Control View of the MMP1 remote App and some extra functions from the Editor.

Beta test software will be available next week, the functions already included are as follows

  • 7.1 setup
  • Gain
  • Mute, Dim
  • Speaker Mute, Solo
  • Input selection and sum
  • Output selection
  • Input trim
  • Metering
  • Phones On/Off and Gain
  • Cal
  • Speaker trim
  • Talkback Enable and Gain
  • Cue Enable and Gain
  • Downmix
Updated July 10th 2018
I also updated the TMC-1 Meters to display a maximum of 8 or 12 channels which will be available on other versions of the TMC-1 software

I am waiting for meter assignment data definitions from Yamaha to finalize the software

New TMC-1-Penta Software for NTP/DAD and Avid MTRX

In the previous post I explained the new Preset selection functionality on the TMC-1. I have just added an enhanced version for the TMC-1-Penta which includes the ability to  select different groups of inputs from the Input Pallet.

The TMC-1-Penta can select between or sum up to 8 inputs which can be assigned from a pallet of 32 inputs. The new input group selection allows you to specify up to 4 groups of 8 inputs and select between them.

Screenshot of the new Preset Page on the TMC-1-Penta configuration program
The table on the left is used to define the presets and includes an I/P Group column. The buttons below may be used to define some standard presets.

The table on the right is used to assign inputs from the pallet to the input groups.

On the TMC-1 there are 6 new user keys as follows
Pset 1, Pset 2, Pset 3 and Pset 4: Preset selection keys (The Preset name is displayed on the key)
Preset: Increment the preset selection - the current preset is displayed at the top of the TFT Screen.
I/P Group: Increment the Input Group - The Inputs are displayed in the TFT screen

A beta version of this software is available on request

TMC-1 and Marti Humphrey's immersive audio setup

Daniel brought to my attention the youtube of Marti Humphrey's excellent presentation of his innovative immersive audio setup.

Not everyone will be able to install the same number of speakers as Marti has in his studio but many may need to  monitor in different formats for example 7.1 film, 5.1 TV, Stereo TV. In this case the ability to switch simply from one format to another is very important.

It is already possible to switch between two setups on the TMC-1 using the A/B switch but it is all to easy to forget a setting. What is required is a simple way to switch between presets that which for confidence also displays the Preset name.

The beta-test TMC-1 software now includes four Presets, New User keys [Pset 1] -[Pset 4] are used to select the presets. On Factory Reset presets 1,2 and 3 are configured as 7.1 Film, 5.1 TV, and Stereo DownMix.

The Presets may be configured using the TMC-1v6 Preset page as shown below. The Presets are used to set a number of variables simultaneously  as follows

Name Displayed at the Top of the TMC-1 TFT screen with the A/B selection.
Input Select Input or No Change
Sur-3dB Used to select between Film  or TV Surround levels
Bass-X Enable/Disable Bass Extension
LFE+10 Enable 10dB extra gain on LFE channel
Format Select Monitoring format
Speaker Select Speaker set or no change

The Suggested Presets may be used to select predefined presets which may then be modified as required

TMC-1v5 Monitor Controller Software

The [A/B] switch functionality has been modified to include the preset name and may be used to switch between presets.

A new user key [Cal-P]  has been added to select the reference level defined by the preset.

I have added user keys to some versions of the TMC-1 for [2.1], [LCRS], [I-Max], [DTS-X], [Auro] as well as [Atmos]. They are not yet fully implemented, I will implement them fully subject to user demand.

Calibration: To allow for multiple formats calibration must be carried out correctly. For a multiformat system we recommend that all the speakers are initially calibrated individually to a SPL of 85dB, Then the 7.1 and 5.1 surrounds are adjusted for 85dB. This allows the Sur-3dB switch to be enabled for film7.1 or 5.1.

To allow for future TMC1-Penta updates Auro, IMax and DTS:X formats have been included but not implemented at this time.

Daniel is working on a number of example OSC pages to run on a IOS or Android based on Marti Humphrey's QSC controls.  Here is an example of a simple Preset page, the graphics are different but the functions are the same. You can use these as templates to create your own remote controls to the TMC-1

TMC-1 Updates

The TMC-1 software is updated when a bug is discovered or to answer a user request, about once a year I go through the software and bring some order to the TMC-1 user interface and the new TMC-1v5-Win/Mac support program. This year I have added improvements to both.

TMC-1 Key Assignment

The TMC-1 is designed to work in different environments including Broadcast, Film, Music and Games. They all have different requirements, for this reason the TMC-1 keyboard is programmable. This can be daunting for the end user and I have tried to make it easier as follows:-
  • The reset options now include a simple Source Selection and Speaker set selection layout. very similar to some existing controllers. 
The meters Page after selecting Factory I/P + O/P

The User key layout showing the  input select and  Speaker Set selection keys

  • The new TMC-1v5-win/mac program now includes a preset page allowing up to 6 keyboard setups to be saved, updated and loaded easily.

The Preset page allows a single click to reconfigure the TMC-1 with a saved setup and single click saving of the current TMC-1 setup.


The calibration tab makes it easier to calibrate the TMC-1 Input and output levels, the headroom and Analog level settings for the TMC-1-Penta are also included.

Included on the Cal page are the Mono, 5.1 surround and 7.1 surround trims (5.1 Surround tim is selected in the image). The surround trims are used when the room is setup for one format and then used to listen to a source of a different standard. For example if you calibrate a room for 7.1 and then playback in 5.1 with Ls and Rs sent to Lb and Rb you will need to attenuate the surround signals. 

The Rename Key also allows the names to be changed from this tab. The password is required to access the gain calibration and is as normal '1984' (Big Brother is Watching).

User Keys

Three additions/changes to the user keys as follows
  • [A/B] user key, improved functionality now includes Input, Output, Gain and Output format a new menu allows the user to lock the A/B settings, the A/B switch will then switch between two fixed settings 
  • [T/B All(x)] user key, the TMC-1 allows you to define two separate talkback zones accessed from the [T/B1(x)] or [T/B2(x)] keys, however this requires that the zones be configured.  The [T/B All] key is simple and direct, talkback is enabled to all cue send outputs simultaneously. The (x) suffix refers to the eXternal or producers talkback enable. 
  • [DftFmt] user key has been removed and replaced by three Advanced Menu's to define the default format settings for the Main, Alt and Mini speaker sets.

Stereo Page

Added for the TMC-1-AMon and TMC-1-Penta, This screen displays the Left and Right channels  with the SLS and H/P cue sends. This screen is selected whenever stereo output format is selected or by the TMC-1-AMon [Meter Cues] user key.


To reduce the number of user setup's some have moved to the advanced setup.


2.1 and LCRS have been added to the format selections. The [LCRS] allows you to set a surround attenuation for mono surround.
