Place the speaker pod on the customer side of the counter top, ensuring it does not cause an obstruction. 8. Speaker pods and staff pods can be either free standing or fixed. Move to step 14 if you do not wish to fix the pods to the counter. 9. Use cable management holes in the counter to run the staff pod and speaker pod cables to the amplifier. If there are not already cable management holes, drill suitable locations near the rear of both the staff and customer sides of the counter. 10. There are 2 fixing methods for the speaker pod/staff pod. Either fix the pods to a surface using (a) the provided double-sided sticky pad or (b) the provided screws. a. To fix the pod in place using the double-sided adhesive pad: i. Remove one side of the liner and adhere this to the base of the pod centrally. ii. Remove the second liner and adhere the pod in its desired location. b. To fix the pods using the screws: i. Screw x2 countersunk screws into the fixing surface at a 28mm distance apart. 28mm ii. Ensure that approximately 4mm of the screw head is above the fixing surface. 90 degrees 28mm User direction Note: Place the screws at a 90 degree angle facing the intended 8 users' standing position. iii. Place your pod onto the screw heads, ensuring these fit into the twist fixing points located on the bottom of the unit: iv. Twist the unit clockwise to tighten it in place. If the pod is too tight or loose, adjust the screws accordingly, then re-attach. 11. To fix the mouse microphone to a surface, use the provided double-sided fixing pad or screw through the screw-hole in its cap. 12. Feed the wires through the cable management holes. 13. Avoid loose or trailing cables. Use trunking or to prevent trip hazards or units being tugged from their position. 14. Route all cabling neatly to the amplifier location on the staff side. 9 Hearing Loop Installation (Optional) The aerial should be fixed under the desk-top or counter centrally on the customer or visitor side, one half mounted horizontally under the counter and the other half mounted vertically, facing the customer/visitor (as in the first scenario below). Position the aerial under the counter using either the provided P-clips or another fixing method of your choice. See the diagram below for recommended positioning. A XB XC A is the optimum layout for a counter hearing loop. B and C are acceptable only if A is not possible and the layout is aligned so that the magnetic field will be directed towards user's head heights. Ensure all hearing loop signage is displayed clearly. 10 Amplifier Setup Overview of Front Panel Buttons On/Off Settings Volume In (Customer/Visitor to Staff) Increase and decrease Setup Volume Out (Staff to Customer/Visitor) Increase and decrease 1. Connect all green plugs to the back of the amplifier, following the locations printed above the sockets (see page 4). 2. Power on the amplifier by pressing the On/Off button. 3. When powered and in normal operational mode the amplifier will display Volume In LED 1 and Volume Out LED 1 as steady green. 4. When the amplifier is switched off, all audio is muted and none of the LEDs are illuminated. Pressing any button will turn the amplifier on again. 5. Adjust Volume In and Volume Out to a comfortable level. 6. Press and hold the Volume In (+) or (-) buttons to increase or decrease the level. The corresponding LED bar will show the volume setting. 6. Ensure the mouse microphones are placed as close to their intended users as possible. 7. Check the amplifier is fully functional by ensuring the red `fault' light is NOT showing on the front. 8. The Amplifier is now set up. Our Window Intercom System amplifiers are pre-set to volume levels suitable for nearly all users. Should you need to adjust the Maximum Volume, Ducking or Hearing Loop levels outside of the pre-set amplifier parameters, use Engineer's Mode (see page 13). 11 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/visitor microphone. · Volume In LED 8 will flash red if there is a fault with the loop (e.g. 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. 12 Troubleshooting Symptom There is no power detected through the amplifier (and there is power at the socket). Possible Fault 1) Power jack not plugged in or faulty. 2) Plug fuse has blown. 3) Faulty power supply unit. Action 1) Check power jack is firmly plugged in. 2) Replace fuse. If it blows again, replace the power supply unit. 3) Replace the power supply unit. The red LED is illuminated on front panel. 4) Faulty amplifier. 1) Constant red LED: Staff or customer/visitor microphone fault. 4) Replace amplifier. 1) Ensure microphone is wired correctly and firmly plugged in. Try alternative microphone to ensure port is working. I can't hear audio through the induction loop. 2) Red LED comes on after speech: Induction loop fault. 1) Induction loop or microphone is disconnected. 2) Ensure induction loop connector is wired correctly and firmly plugged in. 1 ) Check instructions for correct connections and, if possible, check the hearing device with a known working hearing loop. I can hear interference through speakers (buzzing / whistling / hissing). Amplifier goes into feedback. 2) Loop tester has a fault. 2) Ensure loop tester has a new set of batteries. 1) Unscreened or poorly earthed third party equipment is being used in close proximity. 1) Switch off any third party equipment to identify the source of interference. 2) Internal volume gain set to high. 2) Access the amplifier Engineer's Mode to adjust the internal settings. 3) Incorrect power supply being used. 3) Ensure that our grounded power supply unit is connected. 1) Internal volume gain set too high. 1) Access the amplifier Engineer's Mode to adjust the internal settings. 2) Microphone positioned too close 2) Move the microphone to a to speaker. location further from the speaker. Unit does not go into power saving mode. 1) Ambient noise in area is too high. 1) Switch off any air con systems, desktop fans and/or computers to reduce ambient noise. If no action is successful please seek assistance from your distributor or a Contacta installer. 13 Engineer's Mode Engineer's Mode allows you to adjust the Volume In and Out levels, Ducking levels and Hearing Loop levels to better suit your environment and achieve the best possible performance. Before entering Engineer's Mode, cycle the power. To do this either: · Switch the power off at the mains socket and back on again · Remove the power connector and re-insert it To enter Engineer's 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 Number 1 LED on the Volume In will flash green to indicate that you are in Engineer's Mode. The on/off and settings buttons in Engineer's Mode operate as follows: Move to the next setup area Save and exit Engineer's Mode The amplifier will automatically exit Engineer's Mode if no buttons are pressed for 2 minutes. There are 3 editable setup areas in Engineer's Mode. 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) Setup Area 1 allows you to adjust the Volume In and Volume Out levels to further optimise the system for the environment in which it is installed. Increase maximum staff volume level Decrease maximum staff volume level Increase maximum customer volume level Decrease maximum customer volume level 14 1. Ensure the customer and staff volumes are turned completely down. 2. Adjust staff (Volume In) volume to a comfortable level. Press and hold the Volume In (+) or (-) buttons to increase or decrease the level. The corresponding LED bar will show the volume setting. 3. Increase customer (Volume Out) volume until feedback is heard. Press and hold the Volume Out (+) or (-) buttons to increase or decrease the level. The corresponding LED bar will show the volume setting. 4. Decrease customer (Volume Out) volume until feedback is eliminated. Setup Area 2: Ducking Adjustment (LED 2 flashes) Setup Area 2 allows you to adjust the Ducking level or to turn it on/off. The ducking function is provided to reduce feedback on a window intercom system. Feedback occurs when the overall setting of both volume controls is too high. The ducking system works by detecting which microphone in the conversation is being used, and temporarily reducing the volume setting. Increase ducking level Ducking on Decrease ducking level Ducking off Setup Area 3: Hearing Loop Drive Adjustment (LED 3 flashes) Setup Area 3 allows you to adjust the Hearing Loop Drive or to turn it on/off. Hearing loops improve communication by enabling hearing device users to hear sound sources directly, cutting out background noise. Increase drive Hearing Loop Drive on Decrease drive Hearing Loop Drive off The drive levels 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, turn the Hearing Loop Drive off as indicated in the diagram above. 15 Further information is available on our website and our YouTube channel.
