Amplifier Setup

Our amplifier provides full open duplex communication and is compatible with all of our speech transfer systems. It features individual displays for staff or customer adjustments and individual fault lights for easy fault diagnosis.
Overview of Front Panel Buttons

Engineers Mode
Before entering engineers mode, cycle the power. To do this either:

• Switch the power off at the wall socket and back on again. or
• Remove the power connector and re-insert it.

To enter engineers mode, simultaneously press and release the following buttons within 20 seconds of cycling the power:

• Settings button
• Volume In increase button
• Volume Out increase button

The on/off and settings buttons in engineers mode operate as follows:

• Move to the next setup area
• Save and exit engineers mode

Please note

• Save and exit engineers mode after making any adjustments.
• The amplifier will automatically exit engineers mode without saving if no buttons are pressed for 2 minutes.

Setup Areas

Whilst in engineers mode, there are 3 editable setup areas. You will always enter setup area 1 first. The green Volume In LED bar will flash to indicate which setup area you are in.
Setup Area 1:
Maximum Volume Adjustment (LED 1 flashes)

• Increase maximum Decrease maximum
• Increase maximum customer volume level
• Decrease maximum customer volume level
• Decrease maximum staff volume level

Setup Area 2:
Ducking Adjustment (LED 2 flashes)

• Increase ducking level
• Decrease ducking level
• Ducking on (Vol Out LED 1 illuminates)
• Ducking on (Vol Out LED 1 turns off)

Setup Area 3:
Hearing Loop Drive Adjustment (LED 3 flashes)

• Increase drive
• Decrease drive
• LEDs illuminate to display loop drive voltage

The drive level should be adjusted so the red LED 8 is illuminated only when there are peaks in the speech volume.
If the amplifier does not have a loop attached, you can turn off the red loop fault LED 8 by adjusting the drive down to off.

Please note: If the amplifier detects an error in its’ settings memory it will restore itself to factory default settings.

Using the System

When powered and in normal operational mode the amplifier will display Volume In LED 1 as steady green.

When the amplifier is switched off using the On/Off button, audio is muted and LEDs are not illuminated; press any button to turn the amplifier on again.

To adjust the staff volume level: Press and hold the Volume In (+) or (-) buttons to increase or decrease the level.
The corresponding LED bar will show the volume setting.

To adjust the customer volume level: Press and hold the Volume Out (+) or (-) buttons to increase or decrease the
level. The corresponding LED bar will show the volume setting.

For best possible performance:

1. Ensure the customer and staff volumes are turned completely down.
2. Adjust staff volume (Volume In) to a comfortable level.
3. Increase customer volume (Volume Out) until feedback is heard.
4. Decrease customer volume (Volume Out) until feedback is just eliminated.

Once you have followed the above steps:

1. The staff microphone is best positioned no more than 300mm away from the staff member.
2. Check the amplifier is fully functional by ensuring the red `fault’ light is NOT displaying.

If there is insufficient volume even after you have adjusted the volume controls, enter engineers mode and raise max volume settings. Exit engineers mode and repeat initial setup.

The system is now ready to use.

Fault Diagnosis LEDs

• Volume In LED 8 will stay red if there is a fault with the staff microphone.
• Volume Out LED 8 will stay red if there is a fault with the customer microphone.
• Volume In LED 8 will flash red if there is a fault with the loop (i.e. a broken aerial).

Factory Default Settings
To return the amplifier the factory default settings:

1. Unplug the power supply and then reconnect it.
2. Press the On/Off button and Volume In (-) button together, then release.
3. The Volume In LED bar will have all LEDs illuminated, while the Volume Out
   LED bar will display the firmware revision number in a fixed pattern of LEDs. This indicates that default settings have been restored.
