Adjusting the Audio System
The speaker (SPK) and microphone (MIC) pots on the audio matrix (see Figure 2) provide the main
volume adjustment for the system. There are a set of pots for each customer lane. The speaker pot
adjusts the outgoing volume to the customer lane while the microphone pot adjusts the incoming volume
to the teller. The best adjustments are made with one person at the audio console and another person in a
vehicle at the customer lane.
Adjust the SPK and MIC pots based on the orientation of a clock with 12:00 being mid range. Audio
matrixes leave the factory with these pots set at approximately 10:30.
If wireless headsets will be used, make all matrix adjustments while in Console Mode using the
console speaker and microphone, not the headset. After the matrix is adjusted satisfactorily then
switch to Headset Mode and adjust the headset using it's own adjustments to balance the volume
levels obtained with the console. Headset adjustment procedures are found in the section "Wireless
Headset Installation".
When using 5512 Remote Handsets, make all matrix adjustments while using the remote speaker
and microphone at the lane, not the handset. Then lift the handset off the cradle and use the pots on
the handset board to balance the volume levels. See the section "5512 Remote Handset Installation".
When using standard audio cable: Select a lane from an audio console and speak directly into the
console microphone at a distance of approximately 3 to 6 inches for 5501 consoles (2" for older
consoles). Adjust the speaker pot on the matrix for adequate but not excessive volume at the lane.
Make small adjustments at a time – approximately 30 minutes. Do not set the pot higher than
absolutely necessary. 5501 consoles with 1.1 or 2.2 firmware should rarely need to be set higher than
10:30 and can often be set lower.
When using Cat 5 cable or standard audio cable with the E0958-KIT: Set pot R1 on the E0958 lane
module to it's maximum setting (fully counter-clockwise). Set the speaker pot on the matrix to 9:00.
Select a lane from an audio console and speak directly into the console microphone at a distance of
approximately 3 to 6 inches for 5501 consoles (2" for older consoles). There should be adequate
volume at the lane at this setting since the amplification takes place at the lane module. Only
increase the speaker gain at the matrix if necessary and then in small 30 minute increments and
retest. See the section "Cat 5 Lane Speaker/Driver Kit Installation".
With the lane still selected adjust the mic pot on the matrix for adequate but not excessive incoming
volume while the person at the customer lane speaks toward the microphone. Make small
adjustments at a time – approximately 30 minutes. Do not set the pot higher than absolutely
necessary. Do not adjust the volume using the console volume arrows at this time. The console
volume can later be adjusted by each teller for their individual preference. Note that any changes
made using the console volume arrows will revert back to a default level whenever the system is
reset.
Do not automatically assume that all lanes should be adjusted to the same settings. Acoustics and
other factors can vary from lane to lane.
Do not expect to hear air noise "hash" any time a lane is selected unless background noise
cancellation is turned off. With a properly adjusted system the console speaker will be quiet until
someone speaks at the customer lane.
The system operates in full duplex mode, meaning audio is active both directions at the same time.
However, to give the teller priority in the conversation, the incoming volume is reduced while the
teller speaks into the microphone.
There is a trim pot on each audio console to adjust the gain of the console microphone. Access to
this pot is from the bottom of the console. In most cases this pot can be left in it's default mid
position. 5501 consoles with 1.1 or 2.2 firmware have much greater outgoing volume than older
consoles. When mixing consoles on the same system this pot can be used to balance the volumes.
