Audio Matrix Switch Settings
Refer to Figure 33 for the dip switch pack located on the end of the audio matrix. Factory settings are
shown in bold. Cycle power to the matrix after making any changes to these switches.

1
Determines whether the console lane buttons work from left to right (normal) or right to left
(reverse). This switch must be UP for 5501 Series consoles.
2
Determines if more than one console can select the same lane at the same time. Volume levels will
be reduced when multiple consoles select the same lane. This switch has no effect with a 5003
matrix.
3
The mute circuit is wired so the closure of an auxiliary contact of the blower relay shorts across the
lane microphone to mute the incoming audio while the blower is running. These switches
determine the length of delay after the microphone short is removed until the incoming audio
comes back on to allow for motor wind down time. The switches can be combined to give a 3
second delay.
4
Noise Abate mutes the auxiliary audio (if used) until the call button is pressed or the lane is put on
hold. This feature is generally used if the facility is near a housing development to prevent
complaints from the residents. This switch has no effect with a 5003 matrix.
5
This determines whether the call tone programming goes back to factory default (erase) when the
system goes through a reset or whether the programming is saved (normal) and only applies to
older matrixes. The programming is always saved with a 5000 Series matrix regardless of the
position of this switch.
6
These switches as listed are for features in all 5501 Series consoles and 5001 Series consoles that
are revision 3.1 or higher. See an explanation of these features in the section "Echo Canceller &
Background Noise Cancellation" later in this document. The echo canceller must be set for
dynamic learning when using 5501 consoles.
MIC DC Switches: These switches only exist on older 5000 Series audio matrixes and are used to
determine if the lane microphone is a Dynamic (UP) or Electret Condenser (DOWN) type. Since the
electret type is standard (and recommended) this switch must be down or the mic will not work. All
newer matrixes are hard-wired to this position and do not include the switches to avoid service issues.
