2.1 Source Selection
Key to the ease of operation of AVM-T-MIX is the simplicity by which audio may be monitored
and/or mixed. As described previously, AVM-T-MIX is equipped with two completely independent
mixer/monitor systems (Mixer 1 and Mixer 2). Each can be configured with its own setup and used
in diverse applications.
Mixer 1 may be used as primary audio monitor in any application whilst the secondary mixer might
be used as a simple de-embedder to ‘back-feed’ another part of the system or even as a means to
derive a headphone cue to a voice over artist or commentator.
Setting up the monitor for use is simple and intuitive yet incredibly powerful.

2.2 Analogue Audio Input Trim
AVM-T-MIX is designed to be used with balanced or unbalanced analogue audio inputs. If one of
the analogue inputs has been wired to an unbalanced signal source then the user may need to
compensate for signal loss (typically -6dB). If this is the case then gain can be added to the chosen
analogue input in steps of 3dB by touching the button displayed below via the Setup/Input menu.
Please note that the AVM-T-MIX does not have an analogue signal amplifier and that the gain is
added in the digital domain. If gain is added to an unbalance analogue audio input in this way then
the signal to noise ratio of that signal will be affected accordingly and low level ‘hiss’ may be heard
in exceptional circumstances.

2.3 Channel Signal Format Selection –Stereo Mix/Mon Modes
Applicable to Stereo Output Mixer Formats Only
Channel formats can be defined as Stereo,
Mono or a Group of 2 or more pairs (including
5.1 and LRC Downmix configurations).
2.3.1 Stereo Channel Format:
To define a channel as Stereo, simply touch the
desired bargraph pair followed by the ‘STEREO’
button from the Format menu (as shown).
The Level Send and format ‘Pips’ below the
bargraphs denote Stereo selection by the use of
Electric Blue colouration
2.3.2 Mono Channel Format:
To define a channel as Mono, simply touch the
desired bargraph pair followed by the ‘MONO’
button from the Format menu (as shown). The
MONO L/R menu is then activated enabling the
operator to choose between ‘Mono (L+R)’, ‘Left
(to Both)’ and ‘Right (to Both)’ formats.
Using the latest available software for the AVM-
T-MIX standard unit, only the chosen or
resultant audio bargraph is represented
The Level Send and format ‘Pips’ below the
bargraphs denote Mono format selection by the
use of Cyan colouration
2.3.3 Group Channel Format:
There are four modes of selection within the
GROUP menu designed to enable the user to
mix and monitor sources delivered in more
complex channel formats.
2.3.4 Group 2 PAIR ADD:
2 Pair Additive mode sums two adjacent stereo
audio pairs together in the format L+L and
R+R. The user can adjust the level of the left
sum against right via the balance control.
2.3.5 Group 2 PAIR OFF:
2 Pair Offset mode sums two adjacent stereo audio pairs together in the format L+L and
R+R however unlike the 2 PAIR ADD mode, the balance control is used to adjust the
relative mix of Pair One against Pair Two.
Pair Offset mode is particularly useful for adjusting the balance of monitored audio when
source material comprises a clean FX track on pair one and a commentary on pair two as
is often common in Sports Broadcasting.
2.3.6 Group 5.1 DMIX:
5.1 Downmix mode sums 3 adjacent pairs in an Lo Ro stereo format assuming that a
standard 5.1 configuration track order has been adhered to (L/R/C/LFE/Ls/Rs) as shown in

P a g e | 17
AVM-T-MIX User Handbook Version Three
the image above. In 5.1 Downmix mode the LFE channel does not form part of the stereo
sum. The user can adjust the level of the left sum against right via the balance control.
The 5.1 Downmix algorithm follows the formula L+(C-3dB) + (Ls-3dB), R+(C-3dB) + (Rs-
3dB).
A user selectable adjustment located within the menu Setup/Setup2/DMIX enables
selection of the a ‘Surround -6dB) coefficient with the resultant formula
L+(C-3dB) + (Ls-6dB), R+(C-3dB) + (Rs-6dB) active depending on the selection.
2.3.7 Group LRC DMIX:
LRC Downmix mode sums 2 adjacent pairs together as a stereo signal with the first
channel of the second pair summed equally to the Left/Right channels. The user can adjust
the level of the left sum against right via the balance control.
The LRC Downmix algorithm follows the formula L+(C-3dB), R+(C-3dB)
The Level Send and format ‘Pips’ below the bargraphs denote a Group format selection by
the use of Magenta colouration
2.4 Channel Signal Format Selection –Surround Sound Mix/Mon Modes
Applicable to 5.1 Output Mixer Formats (see section 2.7.1)
When Mixer One is set to 5.1, additional channel format selections can be made in order to
route 5.1, stereo and mono signals to the appropriate surround sound output channels
2.4.1 Stereo Channel Format:
When operating with Mixer One set to 5.1, an
extended format selection option appears within
stereo channel format options. The operator
can choose by touch to route a stereo pair to
either the front or rear stereo left and right
channels
In the example shown you can see how SDI1
pair 9 is routed to the front left and right
channels and SDI pair 10 to the surround left
and right channels respectively. Front channel
routing is denoted by the Electric Blue or
colour and rear channel routing, by the Silver
colour.
2.4.2 Mono Channel Format:
When working on a 5.1 project a mono channel
selection enables the user to route mono audio
to anywhere across the image of the front
speakers (left, centre, right). This is achieved
using a divergence control that appears within a
mono mode adjacent to the left right panner.
In the example shown the mono channel
selection routes a chosen signal to the centre
mix channel only and the divergence (denoted
D:C) is highlighted in yellow and set to zero. By
pressing the encoder, the operator can toggle
between gain, pan and divergence controls
which can then be adjusted to vary the signal level sent to the centre, left and right
channels respectively thus providing complete control over the mono image across all
three channels.

P a g e | 18
AVM-T-MIX User Handbook Version Three
2.4.3 Group Channel Format:
The four modes previously described for stereo mixer use (2 pair ADD, 2 pair OFF, 5.1
DMIX and LRC DMIX) remain active when a 5.1
mixer mode is activated however an additional
mode, 5.1 ALL, now appears under the
Grouping menu.
2.4.4 Group 5.1 ALL:
The 5.1 ALL mode is used to define a group of
signals that represent a 5.1 programme and
route them in order to the 5.1 mixer channel
output as shown in the image adjacent. A 5.1
ALL group when selected is represented by the
Yellow colour of the menu button and gain
control icon.
In this mode it is assumed that the audio
channels are presented in the order Left, Right, Centre, LFE, Left Surround, and Right
Surround and are routed to the mixer accordingly.

P a g e | 19
AVM-T-MIX User Handbook Version Three
2.5 Monitoring Input Channels –Solo Function
Similar to a traditional rackmount audio monitoring unit, the AVM-T-MIX is used to listen to
incoming signal sources –either exclusively or additively. The simplest way to achieve this is to
touch the bargraph channel you wish to hear and then to select SOLO.
The selected signal will automatically be routed to the loudspeakers (internal or external) and to
the headphone socket.
The example above shows how an operator can quickly check an incoming Programme
audio signal which has been Downmixed to stereo from 5.1. In SOLO Mode. He/she
can now simply touch the adjacent 5.1 bargraph group labelled PGM2 in order to
compare the two signals or alternatively touch the SOLO buttons beneath another
bargraph pair to add the signals to the monitoring output.
The selected SOLO channels are automatically routed at unity gain to the output as
denoted by the position of the rotary SEND icon.
In SOLO mode, any MIXER routing configurations on either MIXER 1 or MIXER 2 are
unaffected.
When MIXER 1 is configured as 5.1 the SOLO function will automatically downmix any
selected channels to the internal stereo speakers or route a defined 5.1 channel group
to the 5.1 external speaker if used.

P a g e | 20
AVM-T-MIX User Handbook Version Three
2.6 Monitoring Input Channels –Mixer Function
One of the unique advantages of AVM-T-MIX over a more traditional Audio Monitoring Unit is
the ability to mix sources together using the same methods found in assignable digital audio
mixing consoles. Mixer 1 and Mixer 2 are both equipped with main outputs which are routed to
the monitoring outputs (loudspeakers and headphones) and to fixed line level Analogue and
AES connections.
Individual bargraph channels can be mixed onto Master Output bargraphs by adjusting the send
level of the selected (highlighted by the yellow ‘box’) channel using the small rotary encoder
simply by turning it clockwise. By pushing and turning the encoder it is possible to adjust the
Balance (for Stereo and Downmixed sources) or Pan (Mono) of the selected output being sent
to the Mixer Master output.
The example above depicts a typical Lines Room application where the operator is
monitoring 3 different incoming language feeds as LRC Downmixes embedded within
the SDI infrastructure on channels 1 thru 6. He/She is simultaneously listening to audio
traffic via an AES router (channels 7 and 8) of Stereo Telco feeds 1 and 2 from another
location plus a mix of local and remote mono Talkback on channels 9 and 10.
The Talkback inputs from the Outside Broadcast and local Studio are panned to the
left and right channels respectively to give separation against the Clean/Native
Language Downmix coming from the OB event.
Channels 3 and 4 plus channels 5 and 6 contain Clean/Alternative Language
Downmixes which are being generated locally from Voice Over Booths with French
and German Commentators.
Mixer 2 line level outputs can be used in this application to provide a Submix of the
Clean International Audio plus Local and OB Talkback to the Commentators via their
local headphone amplifiers.
Mixer 1 can be configured to operate in 5.1 mode. When selected via the setup menu
Setup/Mixer/Surround the main output of Mixer 1 comprises a full 5.1 buss structure
of Left/Right/Centre/LFE/Left Surround/Right Surround that can be used for
external monitoring (via externally connected surround sound speakers) and also
delivers a fixed level 5.1 mixer output to both analogue and AES output connections
Even when Mixer 1 is configured for 5.1 use a parallel stereo version of the mixer runs
as a background application and can be used as an alternative auto-downmixed output
or for stereo monitoring (including internal and headphone outputs on the T-MIX itself).
