About the ASA Series

The Extron ASA series high-performance audio summing amplifiers convert stereo audio signals into balanced or unbalanced mono signals. The series consists of the following three models:

ASA 101 — The ASA 101 is a single, ultra-compact passive summing adapter with two male RCA pigtail connectors for one unbalanced stereo audio input. The unit has one 3-pole captive screw connector for one balanced or unbalanced mono output.

ASA 204 — The ASA 204 has four independent active summing amps with four pairs of RCA connectors for unbalanced line level stereo audio inputs. The unit has captive screw connectors for four balanced or unbalanced mono outputs. Because of its input/output configuration, the ASA 204 can also function as an unbalanced to balanced audio converter.

ASA 304 — The ASA 304 has four independent active summing amps with four 5-pole captive screw connectors for balanced or unbalanced line level stereo audio inputs. The unit has captive screw connectors for four balanced or unbalanced mono outputs.

The ASA 204 and ASA 304 include an external 12V power supply that accepts 100-240VAC input. The ASA 101 is a passive

Furniture, projector, and rack mountability — The ASA 204 and ASA 304 can be mounted under a desk, podium, or other furniture, or secured to a projector mount with optional brackets. Alternatively, they can be mounted on an optional VersaTools™ or universal rack shelf. The ASA 101 can be mounted in many convenient spaces using the supplied double-sided Velcro® tape.

DIP switch selectable audio gain — Each ASA 204 and ASA 304 has a DIP switch that can be set to achieve unity gain with either balanced or unbalanced output wiring, or ±6dB for level shifting.

ASA Series specifications

The Extron Electronic ASA Series is a standout line of advanced audio signal processors renowned for its exceptional performance and versatility. Designed to cater to professional audio applications, this series offers a variety of features that ensure high-quality audio management in various environments, including corporate, educational, and entertainment venues.

One of the main features of the ASA Series is its ability to process multiple audio channels simultaneously. This capability is vital for applications where managing numerous audio inputs and outputs is essential. The ASA Series typically includes a range of inputs such as microphones, line-level sources, and even digital audio formats, giving users the flexibility to integrate various audio sources seamlessly.

Another significant characteristic of the ASA Series is its advanced processing technologies. The processors within this series are equipped with sophisticated algorithms that facilitate noise reduction and equalization, enhancing overall audio clarity. Additionally, automatic gain control (AGC) ensures consistent volume levels, providing a smooth audio experience irrespective of the source dynamics. This is especially critical in environments like conference rooms, where the variance in speaker volume can be substantial.

The ASA Series utilizes Extron’s advanced control technologies that allow for easy operation and integration into existing systems. Users can manage audio settings through a user-friendly interface, enabling quick adjustments when necessary. The models in the ASA Series also support networked audio, allowing for remote control and monitoring capabilities from a centralized location. This feature is particularly beneficial for venues with complex audio setups requiring frequent changes.

Built-in DSP (Digital Signal Processing) is another hallmark of the ASA Series, providing a range of customizable audio effects and presets. This empowers users to tailor audio output according to the specific acoustics of a space or the requirements of a particular event, ensuring optimal sound quality at all times.

Additionally, the ASA Series devices are designed with robust build quality and reliability in mind, ensuring they can withstand the demands of professional use. Their compact design allows for installation in confined spaces, making them suitable for diverse applications.

In conclusion, the Extron Electronic ASA Series elevates audio management to new heights with its advanced features, cutting-edge processing technologies, and user-friendly controls. Whether for corporate presentations, educational settings, or live events, the ASA Series delivers a reliable solution for high-quality audio processing and distribution, making it a preferred choice among audio professionals.
