2.0 Operation.

The PAM2-3G16 is designed to be user friendly and intuitive to operate. The menus and functions will

feel familiar to both users of TSL multichannel audio monitoring products and those buying a TSL

solution for the first time.

Important Note: PAM2-3G16 ships with a default 0dBu reference level set to

-18 dBFS, the default operating scale is EBU Digital. A simple power up sequence may be used

to alter the operating reference level to -20 dBFS with a default EBU Digital operating scale.

For -20 dBFS default operation – apply DC power to the rear power connector whilst

simultaneously pressing buttons 6 and 8. The following message will appear on the right hand

OLED signalling a successful operation.

“Default memories cleared Restored Factory - 0dBu = -20dBFS”

For -18 dBFS default operation – apply DC power to the rear power connector whilst

simultaneously pressing buttons 6, 7 and 8. A message will appear on the right hand OLED

signalling a successful operation.

“Default memories cleared Restored Factory - 0dBu = -18dBFS”

P a g e | 15

PAM2-3G16 User Handbook Issue 4

2.2.4 Dolby E Timing and Rate Information

The Data Screen of the PAM2-3G16 displays extended information about any Dolby E and Dolby

Digital sources. This shows the frame rate of the Dolby encoded signal and its timing relative to a

video source where available.

For AES inputs, the frame rate information is displayed as a minimum;

Dolby E 20bit 29.97 - or - Dolby E 16bit 25Hz

For embedded Dolby E sources, the start line position is displayed in the format;

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 and Digital Plus 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

2.2.5 Dim Cut Control

The rotary volume control of PAM2-3G16 also features a push switch cut/dim function. Push the

volume control once to cut the volume to internal speakers, headphones and variable audio outputs.

Pushing the volume control a second time will dim the output level by 12 dB. A final push will return

the output volume to full level – this is indicated by a single LED dot cursor in cut and dim conditions.

2.2.6 LED Brightness Settings

The Setup 2 Menu contains a button to select the operational brightness of the switch and encoder

LEDs. By selecting and rotating the encoder the overall brightness of the LEDs may be changed from

low to high level across 5 graduations. 1 is low, 5 is high.

P a g e | 17

PAM2-3G16 User Handbook Issue 4

2.4.3 AES Input

2.4.4 Optical Input – PAM2-3G16 is unique amongst rack mount audio monitoring products in that

it features a TOSLINK Optical Input. The Optical Input is selected via Factory Preset 5. When Optical

is selected, AES channel 8 is replaced by the signal received via the Optical connector. This input

may be used to connect directly to a Set Top Box, DVD or CD player and can decode Dolby Digital

or Dolby Digital Plus encoded signals.

2.4.5 Analogue Input

PAM2-3G16 features 6 stereo analogue audio inputs. These may be selected simultaneously by

selecting Analogue from either the monitoring menu or preset buttons. Bargraph pairs 1-6 will display

the respective input audio, pairs 7 and 8 are not used in this mode.

2.5 SDI Input and Video Confidence Display

The Video Display may be activated using button 10 when not in Menu mode. The input video signal

of the SDI Input selected last will be routed to the screen when the audio input selected is either AES

or Analogue.

P a g e | 18

PAM2-3G16 User Handbook Issue 4

2.6 Monitor Menu

The Monitor Menu is used to activate listening modes not accessible via ‘Scroll To Hear’ selection.

2.6.1 The Monitor Menu features a ‘Phase Swap’ button which enables the user to reverse the

phase of the right signal of a selected audio pair with respect to the right.

2.6.2 Pushing to select L – R enables individual selection of either Left or Right components of the

highlighted stereo pair (or pairs).

The L – R function also enables Left and Right audio components to be swapped.

2.6.3 The Mono mode button mono’s the selected bargraph pair

P a g e | 19

PAM2-3G16 User Handbook Issue 4

2.6.4 When Mix Mode is activated, multiple bargraph pairs may be selected and monitored as a

mixed stereo pair.

2.6.5 Downmix Mode allows the operator to select an adjacent group of 3 audio pairs (6 audio

channels) and create a stereo Downmix.

By repeatedly selecting the DnMix button, the group of selected audio pairs move from left to right

across the bargraph display enabling the user to Downmix discrete 5.1 or 5.0 audio from any location

within the 16 channels displayed. Pressing and rotating the Downmix button also enables the user to

scroll through the pair’s selection in the sequence 123, 234, 345, 456, 567 and 678, downmixing the

appropriate surround sound audio signals as desired.

The Downmix Mode assumes that audio channels are presented in the correct SMPTE order (L, R,

C, Lfe, Ls, and Rs). The Downmix Mode uses the ITU-R BS.775 algorithm standard.

Once the 5.1 audio components are selected and Downmixed, the selection can be stored as a

User Preset to a Hotkey (see Storing User Presets) and recalled at the press of a button.

P a g e | 20

PAM2-3G16 User Handbook Issue 4

2.6.6 Split Mono Input Selection

The Scroll to Hear function of the PAM2-3G16 features a special operational mode which enables

the operator to select to listen to two non adjacent mono audio channels.

By scrolling the yellow Hear Box to the first of the desired mono channels the LEDs on either side of

the rotary encoder will flash for a period of 3 seconds. During that time the user is permitted to turn the

encoder (without pressing) to select a second non adjacent mono audio signal. Once the selection is

made the LEDs will stop flashing and the resultant selection is heard through the loudspeaker or

headphone outputs.

Note; A Split Mono selection is indicated on the front left hand screen in the lower right text window.

The selection may be saved as a User Preset for instant recall (see Saving User Presets).

Note; Split Mono selection uses the Assign Matrix section of the PAM2-3G16 in order to create a

pair of non consequential audio channels. When a Split Mono pair is defined, the Assign Matrix

represents the resultant signal selection as illustrated below.
