 Compact, lightweight (3.6 Kg) 1RU case, 320mm deep

The TSL PAM1-3G8 offers the best sound quality and level ever obtained from a 1U box. It does
this because the sonic properties have received the same attention to detail as the rest of the unit.

The PAM1-3G8 has a custom-designed woofer of extremely slim construction, despite which it
out-performs many drive units built with no such constraint. The large aluminium voice coil and
rare earth magnets make the unit relatively efficient and combined with the switched-mode
amplifiers a remarkable sound pressure and wide frequency response can be obtained without
excessive power dissipation. As a result of the efficiency, traditional techniques such as reflex
ports are not needed, and the timing and phase errors these cause are eliminated.

The sound quality could easily be compromised if the enclosure were allowed to resonate. In the
PAM1-3G8 the enclosure was designed from the outset to damp unwanted vibrations. Even the
grill material was selected for the most transparent sonics. It is the same material that is used to
protect many of the world‟s finest microphones.

In traditional loudspeakers, the crossover is responsible for a lot of quality loss. A crossover should
produce a pair of signals which, if added back together, should recreate the original input. In most
loudspeakers, this doesn‟t happen, whereas in all of TSL‟s active speakers that performance is
standard. In the PAM1-3G8 the crossover is performed in the digital domain and the accuracy
obtained contributes to the smooth sound and fatigue-free listening characteristics.

John Watkinson, February 2009

PAM1-3G8 Version 7

Operation.

The PAM1-3G8 is designed to be user friendly and intuitive to operate. The menus and
functions will be familiar to both users of other TSL multichannel audio monitoring
products and those buying a TSL solution for the first time.

2.1 Controls and Displays

1. The left hand OLED screen displays bargraphs 1-4 in Full-screen mode and bargraphs 1-

8 in Menu mode (shown).

2. The right hand OLED screen displays Bargraphs 5-8 in Full-screen mode, Menu, Preset

and Metadata information in Menu mode (shown). The right hand OLED screen also
displays the Video Confidence Window.

3. The rotary encoder performs multiple functions. Push and rotate actives the „Scroll to

Hear‟ monitoring feature. Push and Release enter the Menu mode. Rotate is used to

recall Factory and User presets.

4. The loudspeaker volume control varies the level of audio to the internal loudspeakers,

external analogue and AES (on D25 connectors when set to Variable mode) and
headphone socket.

5. Hotkey button 3 instantly recalls an assigned User or Factory preset state.

6. Hotkey button 2 instantly recalls an assigned User or Factory preset state. In Menu

mode, button 2 is illuminated green and is used to activate the Save to Preset function.

7. Hotkey button 1 instantly recalls an assigned User or Factory preset state. In Menu

mode, button 1 is illuminated red and is used to scroll Back through the Menu modes.

8. The bargraphs pertaining to the audio being routed to the internal and external

loudspeakers is outlined by the yellow Hear Box.

PAM1-3G8 Version 7

2.2 Main Menu

The example below shows PAM1-3G8 in normal dual screen Metering Mode listening to
the LtRt Downmix from a decoded Dolby Digital audio bitstream.

Press the Encoder to access Main Menu. The encoder is then used to highlight and
select from the displayed Menu options. From any Menu, pressing Hotkey 1 (illuminated
red) will exit the current menu page.

The Main Menu screen also displays information about the current selected input signal as
shown in the photo above.

2.2.1 Dolby E Timing and Rate Information

From software version X06, the top level menu of the PAM1-3G8 shows extended
information about any Dolby E sources. This shows the frame rate of the Dolby E

information and its timing relative to a video source where available.
For AES inputs, the frame rate information is displayed as a minimum, eg:

Dolby E 20bit 29.97 - or - Dolby E 16bit 25Hz
For embedded Dolby E sources, the start line position is displayed, eg:

Dolby E 16bit L11
This functionality is also extended to mixed sources. If an AES source is selected for

monitoring, whilst a video source is selected with the same frame rate, then the display will
give the approximate line position of the AES Dolby E start relative to the video. This
allows the timing of an AES signal to be checked either before embedding or after
extraction (note the embedder / extractor delays need to be accounted for in a system).
For sources of different frame rates, the display reverts to the Dolby E frame rate. The
video frame rate is already displayed on the top level menu.

Dolby Digital sources are also identified, although no further information is provided
without a decoder.

All of the above functions are available both with and without on-board Dolby decoding,
providing the source has a correctly formatted SMPTE 337M header

PAM1-3G8 Version 7

2.3 Input Selection

By highlighting and selecting the Input option, SDI, AES and Analogue inputs can be
accessed. A shortcut button enables the user to „jump‟ to the Monitor Menu once the
desired input is selected.

2.3.1 SDI Input and Video Confidence Window
Select either SDI Input 1 or 2 and choose which pair of embedded groups is to be

decoded and displayed. Default selection is Group 1 and Group 2, by de-selecting a
group and then selecting another choice, any pair can be decoded.

Note:
If a selected audio pair is encoded with either Dolby E or Dolby Digital, it will be decoded
automatically and the discrete audio stems displayed.

A Video Confidence Window may be displayed on the right hand OLED screen. This
feature is selected and enabled using the Setup Menu as shown on the following screen.

By selecting the Video menu option, the select SDI video source is displayed on the
OLED screen. The Video button allows the user to manually select the input video aspect
ratio. A 16:9 or 4:3 aspect ratio video output to the OLED screen and Downconverted
output is selected using the appropriate DIP switch located at the rear of the unit.

Save your SDI input selection to a User Preset –

See the Using Presets section of this Handbook.

PAM1-3G8 Version 7

2.3.2 AES Inputs
Selecting AES simultaneously displays AES inputs 1, 2, 3 and 4.
Note:

If a selected audio pair is encoded with either Dolby E or Dolby Digital, it will be decoded
automatically and the discrete audio stems displayed.

PAM1-3G8 detects the channel coding information of a Dolby E or Dolby Digital
bitstream and identifies the audio stems accordingly (as shown in the example below).

Save your AES input selection to a User Preset –

See the Using Presets section of this Handbook.

2.3.3 Analogue Inputs
Selecting Anlg simultaneously displays stereo Analogue inputs 1 and 2

PAM1-3G8 Version 7

2.4 Monitoring and Monitor Menu

The Monitor Menu has been adapted since this Handbook was written and the images
used to describe the menu are partially incorrect. The graphic below shows the revised
Monitor Menu including adapted features described below.

The Monitor Menu includes a „Phase Swap‟ feature which enables the user to reverse the
phase of the right signal of a selected audio pair. In order to accommodate this feature a
fundamental change to mono audio selection functions has been implemented.

The former „Left‟ button now becomes “L – R”. The choice of mode is selected by

pushing the encoder and turning giving „Left‟, „Right‟ and „Swap‟ to stereo outputs. The

function is enabled when highlighted “green)
The former „Right‟ button becomes „Phase‟. When highlighted (green) this reverses the

phase of the selected right audio signal through 180 degrees.

2.4.1 Scroll to Hear

! Introduced on PAM1-3G8 from January 2010 via the X06 software release, the Scroll to

Hear function fundamentally changes the way the navigation encoder works. Within

previous versions the encoder was used to select presets and to activate and navigate
through the PAM1-3G8 menu structure.
Note that the push and rotate action used to implement the „Scroll to Hear‟ feature is now
active within some but not all of the PAM1-3G8 menu pages. Please take time to
familiarise yourself with the new look and feel of PAM1-3G8.

The encoder may be used to move the „Hear Box‟ dynamically across the bargraph
display without reverting to the monitor menu. The operation is described below.

PAM1-3G8 Version 7

The Scroll to Hear function can only be activated when the PAM1-3G8 is operating at a
top level view and is inoperative when the menu or metadata screens are active.

Using „Scroll to Hear‟ with Dolby encoded audio

If the source audio pair selected is encoded with a Dolby E or Dolby Digital then the
PAM1-3G8 will automatically decode the signal and display the component parts of the
Dolby signal as soon as the encoder is released. The individual components (as pairs) of

the Dolby signal can then be selected using the „Scroll to Hear‟ function and if the „Hear
Box‟ is scrolled to the right of the bargraph display, then an Lt Rt or Lo Ro Downmix will

be automatically selected and represented on bargraph pair 4.
To deactivate the Dolby encoded screen, simply push and hold the rotary encoder for

more than one second without turning it and the display will revert to display the
associated top level or non decoded audio signals associated with the currently selected
input type.

By highlighting and selecting the Monitor option from the Main Menu, bargraph pairs,
multiple audio stems and downmixes may be routed to the internal and external
loudspeakers.

2.4.2 Mono and Stereo Monitoring (Non Dolby or Discrete Multichannel)
Individual bargraph pairs can be selected from the Monitor Menu as shown below. The

Yellow Hear Box denotes which audio pair is routed to the internal loudspeakers and
headphone socket. Left/Right/Mono options can be chosen so that individual stems can
be isolated or mixed (shown).

PAM1-3G8 Version 7

2.4.3 Dolby E or Dolby Digital Monitoring
When a Dolby E or Dolby Digital encoded audio pair is selected, PAM1-3G8 will

automatically decode the signal into its component parts and name the stems according to
the Channel Coding information carried within the Metadata. The Monitor Menu screen
changes dynamically to reflect the selection of a Dolby encoded source and the Monitor
buttons now include options pertinent to the Dolby signal (see below).

A Dolby Lt/Rt (or Lo/Ro if selected via the rear panel DIP switch) option appears and
when selected, a Dolby Downmix is derived by PAM1-3G8 and routed to the
loudspeakers. The Lt/Rt (or Lo/Ro) level is displayed on the 4th bargraph pair (see below).

Dolby monitoring modes allow the user to select to hear individual audio

pairs and stems. The example in the screenshot below shows how to „solo‟ the Centre
Channel and listen to it through the internal or external loudspeakers.

Monitoring using external loudspeakers

De-embedded or decoded multichannel audio (Dolby or discrete PCM) is automatically
routed to the AES and analogue outputs connectors. The rear panel located DIP Switch
includes a selection to mute internal loudspeakers and to set AES and analogue outputs
to variable level (adjusted by the volume control).

Stereo or 5.1 external loudspeakers can be connected (see the application diagram
below).

Dolby E and Dolby Digital
The Dolby monitoring menu includes options called ALL and DRC. When used with a 5.1
loudspeaker monitoring system ALL routes the decoded 5.1 audio to the multichannel
outputs. In DRC mode, the Dolby decoded 5.1 output is affected by Dolby DRC metadata
and adjusted accordingly. If the monitoring mode is switched away from ALL or DRC then
the Centre, Lfe, Ls and Rs speaker channels are muted and only the Left and Right
channels are active. The 5.1 monitoring selections enable a user to „solo‟ individual
surround sound signals to check the integrity of the audio mix.

PAM1-3G8 Version 7

Discrete PCM 5.1

The non-Dolby monitoring menu also includes an ALL option. By selecting ALL the
operator can select the group of 6 audios from 2 groups which corresponds to the 5.1
audio signal. Once a 5.1 group has been defined, the 5.1 audio stems are routed to the
external speaker outputs in the correct SMPTE order (L,R,C,Lfe,Ls,Rs). Monitoring
selection options now function similarly to those within the Dolby Menu and include an
ITU775 Downmix option similar to the LtRt mode.

By pressing ALL for a second time (illustrated below), the yellow HEAR box shifts to
highlight an alternative group of 6 audio stems. This function ensures that an embedded
discrete 5.1 signal can be monitored regardless of the location of the 5.1 stems. The user
can store different settings for monitoring discrete 5.1 audio in their User Presets.

The Downmix listening mode is also useful when using the internal loudspeakers to

monitor discrete 5.1 audio channels.

PAM1-3G8 Version 7

2.4.4 Internal and External Monitoring Modes
The table below indicates the various monitoring modes available to PAM1-3G8 users and

the audio signals presented to internal loudspeakers and external connectors when each

2.5 Metadata Menu

Primarily for use with Dolby E and Dolby Digital encoded audio signals, the Metadata
Menu accesses a user selectable group of 7 Dolby Metadata parameters. By highlighting

and selecting any of the 7 options, the user can use the encoder to scroll through a list of
25 commonly used Metadata settings for Dolby E and Dolby Digital audio and create
their own Metadata monitoring view.

Dolby E signals might consist of up to 8 separate programmes (ie: 5.1+2 contains 2
programmes, 2+2+2+2 contains 4 programmes etc) and each programme may be
configured with different Metadata parameters. The Setup Menu allows the user to select
which programme the Metadata is read from. The screen below shows the E prg#
selection on the Setup window. By selecting E prg# the user may scroll through Dolby E
programme numbers 1 to 8 and select the appropriate programme number. This setting
may be saved as part of a user preset.

The example below shows the selection of Dolby E PGM 1 as the default for the Metadata
screen associated with the selected 5.1 audio signal.

The examples below show Metadata displays configured to monitor Dolby Digital and
Dolby E respectively.

Metadata screens can be customised and stored as User Presets.

PAM1-3G8 Version 7

2.6 Setup Menu 1 and 2

Setup Menu 1 includes options for different Scales, Reference Levels, Peak Hold,
Dolby E programme, Dolby E Video compensation delay, Video Window, Mix mode
select and Bargraph Styles. By highlighting and selecting a parameter, the user can

scroll through the available options and tailor PAM1-3G8 for their particular application.

2.6.1 Bargraph Settings
The bargraph example below shows a selected EBU Digital scale with -18dBFs reference

level, Peak Hold is „on‟.

The example below shows the previous EBU Digital bargraph scale changed to display a
BBC PPM bargraph.

The dBFS parameter can be used to alter the 0dB reference level from between -12 and ­24 dBFS. The Zero parameter selects the offset level between the Zero dBFS setting and
the onset of Peak indication (the point where the bargraph changes colour to red).

When set to Block mode, the Peak parameter enables the user to choose to illuminate the
indication between zero dBFS and the peak level in yellow.

The Hold parameter activates a peak hold indication when switched on.

2.6.2 Dolby E Programme No.

The function of the Dolby E Programme Number selector is described in Section 2.5

2.6.3 Dolby E Video Delay

The PAM1-3G8 features a 1 frame (40 ms) video delay setting which can be inserted
into the Downconverted video display to compensate for the latency caused by decoding
a Dolby E signal. If selected and activated, the delay will be switched into the video signal
path automatically when a Dolby E input signal is detected and decoded. The Video
Confidence window on PAM1-3G8 will be subject to a 1 frame delay when the video
delay mode is active.

PAM1-3G8 Version 7

2.6.4 Video Confidence Monitor

The function of the Video Confidence Monitor selector is described in Section 2.3.1

2.6.5 Mixer / Downmix Mode Selector

When monitoring Dolby encoded or discrete surround sound audio, it is often desirable to
listen to a Downmix (stereo fold down) of the multichannel signal. The Mixer / Downmix
Mode Selector activates an ITU-R BS.775-1 Downmix algorithm. The Downmix function
is then made available on the Monitor Menu page for both Dolby and discrete
applications. Where a Dolby encoded signal exists, the Downmix feature offers an
alternative to the Dolby Lt Rt and Lo Ro fold down. In the case of a discrete 5.1 signal,
the Downmix feature can be „toggled‟ between the audio pairs 1/2/3 and pairs 2/3/4 giving

complete flexibility when monitoring embedded signals with multiple audio „programmes‟.

In the example below, a Dolby E signal is Downmixed using the ITU-R BS.775-1
algorithm instead of Dolby Lt Rt.

2.6.6 Setup Menu 2

Setup Menu 2 is used to access the system software page described in Section 2.8 and
also to enable a supervisory user to lock User and Hotkey presets (see Section 2.7.4)

From software version X06 onwards, Setup 2 also provides access to GPI modes as
described.

PAM1-3G8 Version 7

2.7 Preset Memories

PAM1-3G8 features 12 Factory and 12 User Programmable Presets, plus 3 Hotkey

buttons for fast save and instant recall of favourite settings.

2.7.1 Factory Presets

Preset list is displayed in the right hand OLED screen. The images below show how a
User Preset location may be selected from a Main Menu screen.

Once the Green save button is pressed the User Save menu is activated. Select and
highlight a User Preset location from the list U1 to U12.

The text boxes in the User Save menu can be used to name a User Preset. Up to 18
letters or numbers are available. The example below shows a memory being named as Lt
Rt. Selecting and pressing Done saves the memory to the chosen location.

To recall a User Preset, rotate the Encoder clockwise to activate the User Preset window
in the right hand OLED screen. Highlight and select to recall a User Preset.

PAM1-3G8 Version 7

2.7.3 Hotkeys
Hotkeys 1, 2 and 3 can be used to store and recall user settings instantly. By pressing

and holding a Hotkey the current monitoring condition is saved to the Hotkey user
memory. Momentarily pressing a Hotkey recalls a previously stored user memory
instantly.

2.7.4 Locking Presets
Both Hotkey and User Presets can be locked to prevent them from being accidentally

overwritten. To access the Hot and User preset Lock feature the operator must access
Setup Menu 2 as described in Section 2.6

The example below shows the Menu Setup 2 screen followed by the User and Hot save
modes switched to „Lock‟ respectively. When User Lock is activated, the Save button is
deactivated and the User Presets can only be recalled but not edited. Similarly, Hot Lock
prevents the Hot Keys from being overwritten.

PAM1-3G8 Version 7

2.8 System Upgrade and CAT552 Reset

PAM1-3G8 is designed to be field upgradeable. The user will need an SD memory card, a
PC and a card reader.

Format the memory card to FAT16 (or FAT as described in Windows XP). The update will
be sent to you by TSL in the form of ZIP file. This must be extracted directly to the

CAT552 option from the Setup 2 menu and then reset the card.

2.9 GPI Application

The rear panel GPI connector functionality can be used to provide two basic modes of
operation. The Setup 2 menu page now includes a button to access the GPI mode
selector. The operator can choose to set the GPI connector to operate in either „Normal‟
or „Custom1‟ modes.

GPI Mode Application

The two modes of GPI operation are described pictorially by the pin out diagram shown
below.

All of the GPI's other than the preset recalls latch in a toggle manner, i.e. one closure to
ground toggles the function ON; the next ground toggles it OFF. In an ON state; the GPI
pin is driven low to allow an LED to be fed from the port. This LED drive is briefly pulsed
high at about 100Hz to allow the port to be read whilst it is driving.

The preset recall GPI‟s in „Normal‟ are mutually exclusive.

! Note that the +5V power from this connector is intended to drive a "1-of-N" LED. If

multiple LED‟s are to be used simultaneously, then a small external supply will be

needed. An internal resistor within the PAM1-3G8 prevents the +5V rail from being
shorted but limits the current available.

Normal Mode

PAM1-3G8 Version 7

Normal mode is intended to enable instant remote recall of user presets 1-4 from an
external manual or automated selector. The ability to remotely Dim or Cut the internal and
external stereo loudspeaker outputs is also featured.

Custom 1 Mode

Custom 1 mode enables remote access to some of the monitor menu features and
additionally the ability to remotely Dim or Cut the internal and external stereo loudspeaker
outputs.

! Note that within GPI mode select, the „Normal‟ operation is the default operational

state. If an operator chooses to use the „Custom1‟ setting he/she must select and save
this mode for each preset saved to memory.

Installed HDC-2T Audio Monitor Module Specification

Overview

This specification describes the HDC-2T Audio Monitor Module.
This module has been designed to monitor a combination of analogue audio, AES3 digital audio
and AES or Dolby E digital audio embedded in SMPTE 259M or SMPTE 292M video data
streams, together with the video content which is output as composite and/or SDI. HD formats are
passed through a simple down-conversion process to the monitoring output.

Mechanical

PCB: 4 layer, 120mm x 376mm with integral BNC and XLR connectors
Component Height: <30mm above pcb surface, <2mm below
<65mm above pcb surface with Dolby E fitted

Power

The module assumes the supply of regulated power will be made available via the power input
connector. Poorly regulated or noisy supply rails may affect the quality of the analogue outputs.
The HDC-2T will accept two feeds of +12V to +24V DC power, approximately 60W typical when
using loudspeaker outputs. This allows dual redundant or external battery operation.
