• INPUT 1 Microphone source connected to the IN 1 Input.
• INPUT 2 Microphone source connected to the IN 2 input (LINE or MIC sockets).
• REMOTE Source selected by the secondary VAIE 2250 via the REMOTE LINK socket (see Note 1 ).
• USB Flash memory device connected to the front-panel USB EXT socket (see Note 2 ).
• NO INPUT No input selected.
Note 1
The output towards the remote station of the secondary VAIE 2250 must be enabled (see point 8.1 “MONITOR Panel”).
Note 2
When the USB source is selected, the display will show a new operational command: ESC = USB CONTROL (see point 8.3.5).
If no peripheral unit is detected as connected to the system, the acronym USB will appear on the display.
8.3.2 Overall volume control of the “music” channel BGM Source
• Use the +/- knob to adjust the volume.
The attenuation setting is visible directly on the display (A), with variations of 1 dB.
The volume that is set is stored for each BGM Source selected.
8.3.3 Adjustment of the music volume for each output zone
• Hold the numerical key of the required zone (from 1 to 6) down and turn the +/- knob.
The output volume is adjustable to any of 5 levels of attenuation in respect of the master volume (A); the attenuation steps are as
follows:
-15dB (maximum attenuation), -9dB, -6dB, -3dB, 0dB (no attenuation).
The volume that is set refers only to the “Music” channel.
8.3.4 Activation and de-activation of music for each output zone
• Press and then release the numerical key of the required zone (from 1 to 6).
The status label (B) will switch between OFF (music disabled) and ndB (music ON and associated output volume).
• Indications on the display
A) General output volume of the BGM Source
B) Status labels of each of the 6 zones:
OFF Music disabled
ndB Music enabled with the associated output volume
CALL Call in progress from a “voice” source (PA Source).
DND Zone disabled, see the “Do Not Disturb” function (see point 8.4.7).
C) C) BGM Source selected for the “music” channel.
D) Vu-Meter for the audio signal active on the “music” channel.
E) PA Source active on the “voice” channel for service announcements.
F) Vu-Meter for the audio signal active on the “voice” channel.
H) System configured for 12 zones with two VAIE 2250 units connected to one another (REMOTE LINK).
Note: The VAIE 2250 system enables service announcements to be made from a PA Source to the required zones while continuing
to broadcast music to all the other zones not affected by the call. When an announcement is being made, the display will show the
source that is being used on the voice channel (E), and the status label of each zone selected (B) will indicate the word CALL.
Service announcements will be broadcast at the volume set for the input of the PA Source (see AUDIO SETTINGS menu) and if
appropriate will also be sent to the zones for which music is de-activated (OFF).
