PANPHONICS External amplifier with USB/AUX/XLR

ADX-31-U is an audio amplifier for Panphonics electrostatic speakers with USB for
digital audio input. It is designed to connect Panphonics Passive Sound Shower and
Compact speakers
to simple audio systems with a direct connection to audio source. ADX-31-U can also
be used in larger and more complex audio installations.
ADX-31-U features:
? USB-input for digital audio,
? AUX input for unbalanced analog audio signals,
? an isolated XLR-input for balanced analog audio signals,
? user-selectable power-up behavior, and
? two preset EQ- filters.
One ADX-31-U 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.
By the digital USB audio connection, it is easy to design and build simple audio systems without interference. Analog inputs serve installations where digital audio is not
used.
The user can select the state of the amplifier after start-up or a power failure with the
selectable power-up feature.

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.
