3. Overview of ADX-21-D
ADX-21-D is a Dante™ enabled audio amplifier for Panphonics electrostatic panel speakers
with remote controlled features. ADX-21-D is designed to connect Panphonics Passive Sound
Shower and Compact speakers to networked audio systems as well as professional analog
installations.
ADX-21-D features:
•user-selectable power-up behavior,
•two preset EQ- filters,
•Dante interface for networked digital audio with AES67 support,
•device control through network with dedicated software or manually from the interface
panel,
•an option to use Dante and analog inputs simultaneously with the device control
software,
•PoE (PD 25.5W) and external PSU, and
•an isolated input for balanced analog audio signals.
One ADX-21-D unit can operate up to:
•3 units of 60X60 Panphonics speakers,
•9 units of 60X20 Panphonics speakers,
•4 units of 120X20 Panphonics speakers,
•or any combination of the above, as long as the total surface area is not more than 3
units of 60X60 Panphonics speakers.
The user can select the state of the amplifier after start-up or a power failure with the selectable
power-up feature. For the three different modes of power-up for the amplifier and how to select
them, see Chapter 5.2.1 Power-up behavior, page 12.
The amplifier also has a user-selectable EQ-filter. The EQ-filter features presets for Presence
and Warm sound. EQ-filters make it easier to adapt Panphonics speakers to different usage
situations:
•The Presence setting is a flat amplifier output with clear and crisp rising panel response.
For example, it can be used in a noisy environment where the sound from the speaker
needs to be heard clearly over long distance.
•The Warm setting is an equalized amplifier output with a warmer sound to compensate
for the rising panel response. For example, it can be used to create a private zone for
more enjoyable listening experience.
For instructions on how to select the EQ-filter, see Chapter 5.2.2 EQ-filter, page 12.
As a network audio amplifier with Dante and AES67 support, ADX-21-D makes it easy to build
and design audio systems ranging from single device to hundreds of different audio devices.
Adding units to the system is simple and can be done with minimum cable runs and
interferences.
The basic features of the ADX-21-D can be controlled with a dedicated software through a
network. It can be powered with PoE for single cord setups or with an external power supply if
PoE is not available.
Analog input serves installations where networked audio is not used or it can be used locally as
a second audio input in networked installations with the dedicated software.

4. Quick start instructions
Make sure you have all the provided equipment (ADX-31-U Amplifier, Power Supply,
Power cord).
1. Connect a Panphonics speaker model with a speakON™ connector to the amplifier
speaker output (15).
2. Connect a media source or a POE supply to a suitable amplifier input:
•Dante input (13) or
•XLR input (14).
If POE is used as a power source, skip to step 6.
3. Connect the power cord to the power supply.
4. Connect the power supply to the amplifier (12).
DANGER
Always connect all necessary cables to the amplifier before you connect the
power source to a power outlet.
5. Connect the power cord to a power outlet.
6. Press the PWR (1) button to turn on the amplifier.
The power indicator (2) light comes on.
7. Choose the applicable input channel with the input channel dial (9) with the indicator
lights:
•XLR channel indicator (10) or
•Dante channel indicator (11).
8. Make sure the media source is at an applicable level to prevent distortion or excess
noise to the amplifier input.
9. Adjust the amplifier output volume to the correct level with the VOL  (6) and VOL  (7)
buttons.
For instructions on how to install the Panphonics Device Control software, see Chapter 6
Software, page 13.
