10 ADX Audio Matrix User Manual
Low-Pass Filter (Low-Pass Mode)
This mode is used to turn any zone output into a dedicated mono low-
pass output for a subwoofer. Additionally, a low-pass zone output can
be grouped with a full range zone output to create a single 2.1 audio
zone. IR and serial group commands (source, volume, and mute) can
then be used to control both outputs (low-pass and full range) together.
See page 11 for instructions on how to set up a zone group and page 18
for source, volume and mute group serial commands.
How to set up a low-pass zone output:
1. On the Source/Zone Naming page, select and name a zone you
wish to designate as a low-pass output. If you are grouping a low-
pass zone with a full-range zone, it is recommended to name your
zones in pairs for clarity. For example, if Zone 1 is labeled “Master BR”, Zone 2 should be labeled “Master BR Sub”, and
so on.
2. On the Zone Audio Controls page, select a zone for low-pass.
3. Select Lowpass from the DSP Mode dropdown menu.
4. Make any desired changes to the Crossover Frequency. Range of adjustment is 40Hz to 240Hz*.
5. On the Groups page, group the low-pass zone output with a full-range zone output (See page 11 for more information).
EQ/Tone Disabled
If no EQ or tone mode is desired select EQ/Tone Disabled from the DSP Mode dropdown. All levels will be at, but previous
settings can be recalled by switching back to ZQ or Tone Mode.
Volume
1. Select a zone.
2. Adjust volume to the desired level*.
3. If your installation requires a xed
volume level from the ADX (i.e.
volume level is adjusted through an external amplier or volume control), select the “Volume
Lock” setting. When an ADX zone is set to “Volume Lock”, it ignores all ADX volume
up/down commands (Serial, Telnet or IR) and remains at a xed full output level.
Balance
1. Select a zone.
2. Adjust left/right balance levels accordingly*.
ADX EQ Presets Page
The ADX includes 10 built-in “Global” EQ presets, which can be used by any zone. By default,
all 10 EQ presets are at and require adjustment for use. The ADX EQ Presets Page allows
you to name all 10 presets and adjust band settings for each.
Modify and Store Global EQ Presets
1. Select a ZQ preset.
2. Name the preset in the ADX Preset Name text box.
3. Make any desired adjustments to EQ sliders*.
* IMPORTANT NOTE: In order to hear your changes, you must transfer all utility settings into the ADX using
the “export” option from the File menu. For real-time ZQ adjustment and monitoring, EQ presets, bass &
treble changes, etc. program the serial commands into a remote control system such as URC, Command
Fusion, or RTI.
