5.2.6 Loudspeaker
Audio is output can be added using the D-type connector at the rear of the panel (additional hardware
required).
5.2.7 Main Volume Control
Turn the Main Volume Control clockwise to increase the intercom volume, anti-clockwise to decrease
the volume.
The current setting of either the Main or Auxiliary Volume Control is displayed as a level bar on the Reply
Key, above the Reply Key text. Turning these controls clockwise or counter-clockwise, increases or
decreases the length of the relevant control bar.
The most recently moved control is displayed. If the Auxiliary Volume level setting is displayed and the
Auxiliary Volume Control is static for 2 seconds, the display reverts to showing the Main Volume level
setting. (The auxiliary level bar is displayed as a broken line to distinguish it from the main level bar).
The level bars are graded in 0.5 unit steps from a minimum setting of 0.0 (off) to a maximum setting of
10.0 (approximately +12 dB). Each 0.5 unit step corresponds to 1 pixel of the level bar. The default
setting for both Main and Auxiliary Volume controls is 5.0 (approximately 0 dB).
Pressing the Main Volume Control invokes loudspeaker cut. The green LED above the Reply Key is
illuminated while the loudspeaker is cut.
5.2.8 Direct Access Key (DAK)
The 4000 Series LCD Key Panels have Direct Access Key (DAK) pushbuttons. These DAKs are used
to make Listen and/or Talk routes to and from the Control Panel or other audio connections. The DAK
can also be assigned to trigger a control event from either the Control Panel or the matrix.
The pushbutton operation is selectable from a range of options and set via the Configuration and Master
Assignment Programming System (CMAPSi) workstation software. The pushbutton actions include:
Contact Vitec Group Communications for suitable External Loud-
speaker options
Your panel loudspeaker reduces volume automatically when a talk key
is pressed. This is to help reduce the chance of howlround (audio
feedback) occurring.
