Outline GTA Series Innovative Power Supply
INTRODUCTION
GTA series amplifier platforms offer a loudspeaker preset library. The presets can be loaded connecting the amplifiers to a PC running ArmoníaPlus through a Fast Ethernet connection. ArmoníaPlus is the default configuring interface that allows system setting and customization of the GTA series amplifier platform. It is available for free from the Armonía website, where a startup guide and in-depth tutorials are alsoprovided: https://armonia.powersoft.it/
Each loudspeaker model has one or more presets, the aim of this guide is to provide help on how to use them and have an overview of each to choose the one which best suits the needs.
The following data is given
- N° of ways, indicates the number of ways for the relative preset, as well as the number of channels required;
- Type of ways, ways description that defines the section of the channel (LF Low Frequencies, HF High Frequencies…).Application, defines the preset contour (Full Range, High Pass, etc.) or use the preset is designed for (Rear Cardio 2+1, Downfill, Bass, etc.);
- Maximum number of linked speakers, shows the maximum number of loudspeakers that is possible to link for each preset. Exceeding the maximum number of elements per channel can result in damage to the amplifier and the speakers;
- Manufacturer EQ, they are a set of equalizations aimed at settling known behaviors (like low frequency compensation due to loudspeakers coupling, air loss etc.). This guide indicates whether the preset model has the MEQs and which one of the two categories (category A and category B). Please, refer to the relative section here below for more details.
- HPF/LPF, preset cut-off frequency: High Pass Filter is given for Top loudspeakers and Low Pass Filter for the Subwoofers.
PRESET LAYOUT
Here’s a little explanation of the preset layout, with delay, gain and equalization configurations. Please, note that the multi-way speaker presets already include all required output channels, which are linked together ensuring that the speaker is driven correctly.
DELAY
All systems are pre-aligned and phase compliant: it means that from the largest system down to the smallest one, all Outline products feature the same phase curve slope. In fact, positioning the enclosures with the front grilles one above the other, the enclosures will be perfectly aligned over time. To align two enclosures, it is sufficient to measure the difference in signal path between the sources to find the delay that must be added to obtain the perfect audio signal sum. So even if you do not have sophisticated measurement systems, you can actually make a good tuning process.
GAIN
Furthermore, the preset structure is designed to use different loudspeaker models of different sizes together (again, from the largest system down to the smallest one), reaching their limiters at the same input level with default Gain settings.
MANUFACTURER EQ
MEQ are a set of equalizations designed to compensate low frequencies (loudspeakers coupling), air loss (long, medium, short throw) or just for High / Low contour equalizations based on configurations and needs. There are two categories (A, B) available:
- Category A: selectable amount of boxes that make up the array to compensate loudspeaker coupling, providing the right contour for the system. The brand new Ai 41 and Ai 81 offer just two options related to use a ‘Single Speaker’ or a ‘Stereo Set’;
- Category B: selectable distance to be covered to compensate the air absorption. A series offers two distinct options for different configurations, as ‘Wall Mounted’ or ‘Free Standing’.

- A Series Manufacturer EQs offer two different options than the other models.
- Category A refers to the use of a ‘Single Speaker’ or a ‘Stereo Set’.
- Category B control the contour plot in ‘Wall Mounted’ or ‘Free Standing’ configuration.
MOVIE
Outline carries out on-going research for product improvement. New materials, manufacturing methods and design upgrades are introduced to existing products without prior notice as a routine result of this philosophy. For this reason, any current Outline product may differ in some aspect from its description, but will always equal or exceed the original design specifications unless otherwise stated.
