OUTLINE TTM and ISA Series Multi Purpose Amplifier

USER GUIDE

TTM & ISA series

Introduction.

TTM and ISA series offer a speaker preset library available on ArmonìaPlus Marketplace. The speaker presets can be loaded connecting the amplifiers to a PC running ArmonìaPlus through a fast ethernet connection. Even though on the TTM series it is also possible to load the speaker presets directly using the touch screen, we strongly recommend that you use ArmonìaPlus to select the perfect configuration of presets.
ArmonìaPlus is the default configuring interface that allows system setting and customization of TTM and ISA amplifiers. It is available for download for free from Armonìa website, where a startup guide and in-depth tutorials are also provided:

Each loudspeaker model has one or more presets, and the aim of this guide is to provide help on how to use them, as well as to have an overview so you can choose the one that best suits your application needs.

The following data is given:

• N° of ways indicates the number of ways for the relative preset, as well as the number of required channels;
• Type of ways is a ways description that defines the section of the channel:
  LF – low frequencies,
  MF – mid frequencies,
  HF – high frequencies,
  MH – midhigh frequencies,
  BS – bass frequencies,
  PA – passive speaker,
  SB – subwoofer,
  RE – rear subwoofer for cardioid configuration.
• Application defines the preset contour or the use the preset is designed for:

FR – full range – maximum frequency extension of the loudspeaker,

HP – high pass – high pass version of the loudspeaker,
SUB – subwoofer – subwoofer application of the loudspeaker,
INFRA – infra application of the subwoofer,
Rear Cardio – rear subwoofer in cardioid configuration (the number 2+1 or similar means how many subwoofers must be front oriented vs how many of them must be rear oriented)
BASS – bass application of the loudspeaker.

• Maximum number of linked speakers shows the maximum number of loudspeakers that it is possible to link for each amp and per each channel. Exceeding the maximum number of elements per channel or amp can result in damage to the amplifier and the speakers.
• Manufacturer EQ is a set of equalizations aimed at compensating known behaviors (like loudspeaker coupling, air loss etc.). This guide indicates whether the preset model has the MEQs and which are the available options. Please, refer to the relative section here below for more details.
• Acoustic HPF/LPF: This value represents the –6 dB ground-plane measurement for the speaker. With this value, you can get an idea of the best match between tops and subwoofers. It’s important to keep in mind that phase-compliant presets can be successfully matched to achieve good summation, provided that the difference between the acoustic high-pass filter (HPF) and low-pass filter (LPF) is within one-third of an octave.

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

Delay.

Almost all the systems are pre-aligned and phase compliant: it means that from the largest system down to the smallest one, the majority of Outline products feature the same phase curve slope, except for all the discontinued products or those dedicated to special applications. In fact, positioning the enclosures with the front grilles one above the other, they will be perfectly aligned over time even using different applications (for example FR and HP). To align two enclosures, it is sufficient to measure the include all required output channels, which are linked together ensuring that the speaker is driven correctly.
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 any sophisticated measurement system, you can actually achieve a good level of system tuning.

In any case, we strongly suggest that you use a measurement software so you can verify the predicted acoustic coverage and compensate any not simulated ambience behaviour.

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 the frequency response of the loudspeakers depending on the mechanical configuration or a specific application. There are three categories (A, B, C) available:

• Category A: selectable amount of boxes that make up the whole array to compensate loudspeaker coupling, providing the right contour for the system. The Ai 41 and Ai 81 loudspeakers offer two options related to as a ‘Single Speaker’ or as a ‘Stereo Set’ use;
• Category B: selectable distance to be covered to compensate the air absorption. A-series offers two distinct options for different configurations, such as ‘Wall Mounted’ or ‘Free Standing’;
• Category C: special application of the loudspeakers.

FAQ:

Q: How do I know which preset to use for my setup?

A: Refer to the Preset Layout section in the manual, considering the configuration and filter specifications to choose the appropriate preset for your system.

Q: Do I need sophisticated measurement tools for delay configuration?

A: While measurement software is recommended for precise tuning, you can achieve a good level of system tuning by following the manual’s guidelines on delay configuration.
