2.3 Shortcut Button and Menu

The Shortcut button is a feature unique to PAM1 MK2. It provides instant access to the most

commonly used menu functions and enables the user to perform the majority of the device ‘hands

on’ functions via just a single button push.

The Shortcut menu is divided into four sections:

 Input Select
 Display Mode
 Monitoring Mode
 Preset Save and Recall

2.3.1 Input Select
The Shortcut menu provides instant access to the SDI1, SDI2, AES and Analogue sources. The

chosen input is routed instantly to the bargraph display and the Shortcut menu exited
automatically.

2.3.2 Display Mode Select
The Display Mode select provides instant access to four display options available for the right

P a g e | 13

You can save this mode to a Hotkey switch for instant recall of the Loudness Histogram view
 Display Mode – Dolby Metadata. This mode is only available when a Dolby signal is

decoded.

PAM1 MK2 User Handbook Issue 1

P a g e | 14

2.3.3 Monitoring Mode Select
The Monitor Mode select accesses five of the most commonly used monitoring modes available

to PAM1 MK2 users. Since the available monitoring modes are generally used dynamically during
hands-on operation, the Shortcut Menu remains open even when a selection is made. The Back
or Shortcut buttons are used to exit the Shortcut Menu after a monitoring mode selection has
been made.

 Monitoring Mode – Downmix
The PAM1 MK2 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.

The example above shows how SDI1 pairs 2, 3 and 4 can be Downmixed to stereo
Once the 5.1 audio components are selected and Downmixed, the selection can be stored to a

Hotkey for instant recall.
 Monitoring Mode – Lt Rt / Lo Ro (Dolby Downmix)
The PAM1 MK2 Lt Rt / Lo Ro (Dolby Downmix) Mode allows the operator to instantly select the

Dolby Downmix mode when decoding a Dolby E, AC-3 or Dolby Digital Plus signal. This mode is
only active when a Dolby signal is present.

PAM1 MK2 User Handbook Issue 1

P a g e | 15

 Monitoring Mode – ALL
The ALL monitoring mode is a feature designed to be used when PAM1 MK2 is connected to an

external active surround sound speaker system. The function defines a group of 5.1 or 5.0 audio
signals that are to be routed to the analogue and AES multichannel outputs and level controlled
via the rotary volume knob.

By selecting ALL the operator can select the group of 6 audios which corresponds to the 5.1 audio
signals. 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, and Rs).
By repeatedly selecting the ALL button, the group of selected audio pairs move from left to right
across the bargraph display enabling the user to route discrete 5.1 or 5.0 audio from any location
within the 16 channels displayed to the external variable audio connectors in order to feed
external active 5.1 speaker systems. Pressing and rotating the ALL button also enables the user
to scroll through the pair’s selection in the sequence 123, 234, 345, 456, 567 and 678.

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 and Hotkey Presets.

When ALL is activated, the PAM1 MK2 internal loudspeakers are muted automatically.
 Monitoring Mode – Mono
When the Mono button is selected, the monitored audio signal stereo signal pair is mono’d (sum

= L+R). Monitoring Mode – Mono
When the Mono button is selected, the monitored audio signal stereo signal pair is mono’d (sum

= L+R).
 Monitoring Mode – Phase
When the Phase button is selected, the left side of the

monitored audio signal is reversed with respect to the right.

Monitoring Mode – Mono
When the Phase button is selected, the monitored audio

signal stereo signal pair is mono’d (sum = L+R).

2.4 Top Level Screen Mode

The example below shows PAM1 in dual screen Metering Mode listening to Group 1 Pair 1 of an
embedded SDI video signal.

2.4.1 Scroll to Hear
Push, hold and rotate the Encoder to move the yellow ‘Scroll To Hear’ box to listen to any of

the 16 embedded audio channels. This is the simplest means to navigate PAM1 and can be used
whenever the unit is not in a Menu or Loudness Histogram mode.

2.4.2 Dim Cut Control
The rotary volume control of PAM1 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.
