1.Power Switch

This push on/push off switch applies power to the AA120M.

2.Power LED

This LED illuminates when the power switch is turned on.

3.Peak LED

The PEAK LED will illuminate when the AA120M is in a clipping condition, caused by excessively high input levels or a GAIN control is turned up too high. An occasional fl ash is OK.

4.Signal LED

This LED will assist you in setting gain structure into the amp. With a source connected to the amp and playing, turn up the channel gain control until this LED just starts to fl ash. Once all the sources connected are playing, the SIGNAL LED may be on solid. This condition is normal.

5.Master Gain Control

The MASTER GAIN CONTROL will raise or lower all the input channels together. A good starting point for setting gain structure is to set MASTER GAIN CONTROL at the 12:00 position, and then adjust the individual channels one at a time.

6.Input 1-6 Controls

The gain for input channels 1-6 are controlled by these rotary controls. The MASTER GAIN CONTROL must be turned up in addition to the input controls for audio to be present at the speaker terminals.

7.Bass Control

Normally set at the 12:00 position, rotating clockwise will increase (boost) bass frequencies by

10dB at 100Hz. Rotating counter-clockwise from the 12:00 position will decrease (cut) bass frequencies by 10dB at 100Hz

8.Treble Control

Normally set at the 12:00 position, rotating clockwise will increase (boost) treble frequencies by 10dB at 10kHz. Rotating counter-clockwise from the 12:00 position will decrease (cut) treble frequencies by 10dB at 10kHz.

AA120M specifications

The Atlas Sound AA120M is a versatile and powerful amplifier designed primarily for commercial and professional audio applications. This robust unit stands out due to its impressive features, advanced technologies, and impeccable sound characteristics, making it a popular choice for venues such as conference halls, schools, and places of worship.

At the heart of the AA120M is its 120-watt output, which ensures that audio distribution is both loud and clear, capable of powering a variety of speaker systems. Its high-efficiency design incorporates a Class D amplification technology that not only enhances sound quality but also minimizes power consumption. This efficient power management results in lower heat output, which prolongs the lifespan of the unit and reduces the need for extensive cooling systems.

The AA120M is equipped with multiple input options, including balanced XLR and unbalanced RCA connectors, accommodating various audio sources. The microphone input features a priority mode, allowing announcements or important messages to override background music seamlessly. This feature is particularly beneficial in environments where announcements are critical to safety and communication.

Sound quality is further enhanced by the built-in EQ controls, allowing users to shape the audio output to suit the acoustics of their environment or personal preferences. The amplifier also offers a low-impedance operation, which supports a wide range of speaker systems, enhancing compatibility across different setups.

Another noteworthy characteristic of the AA120M is its built-in limiter circuitry, designed to prevent audio peaks that could lead to distortion or damage to connected speakers. This protective feature makes it an ideal choice for public address systems where audio integrity is paramount.

Additionally, the amplifier includes a sleek, rack-mountable design, making it easy to integrate into existing audio setups. Its durability and reliability ensure that it can handle extended use without compromising performance.

In summary, the Atlas Sound AA120M is a multifunctional amplifier that combines power, efficiency, and flexibility. With its advanced features and technologies, it stands out as a compelling choice for anyone looking to enhance their audio experience in commercial or professional settings, delivering clear and powerful sound with every use.
