Setting up the SUB120

CONFIGURING YOUR SPEAKER SYSTEM

Before you start plugging in cables, you should take a minute and decide how you want to interface your new subwoofer. There are several ways you can interface the SUB120 and two specific categories should be consid- ered. First, Stereo vs Mono operation, and second, whether High (powered) or Low (line) level inputs and outputs will be used.

Common Sub Operation

In most cases, a common sub ( mono) bass operation is desired. This is true for several reasons, but mostly because low frequencies produced by a subwoofer tend to be non-directional. Since low frequency waves take so much space to actually develop, you can’t tell if the sub-bass is coming from the left or right side. Unless of course you’re in a very large room. Because of this phenomena, just about all sub-bass material is mixed in mono.

Stereo Sub Operation

 

Two SUB120’s can be used in stereo in larger control

 

rooms for increased low end. In addition, two

 

SUB120’s can be used in stereo, even in smaller con-

 

trol rooms, to help minimize standing waves. By using

 

two subwoofers at lower power, you can achieve a

 

more even response throughout the room.

Placing the SUB120

Because the low frequencies reproduced by the SUB120 are non-directional, you can position the unit almost anywhere. It is however, a good idea to keep the SUB 120 away from corners. Ideally the SUB120 should be positioned in the middle, and up close to, the wall you are facing in the mixing position.

Operating the SUB120

SUB120 Control Panel

The SUB120’s control panel provides the connections and user interface to the SUB120’s internal electronic crossover and power amplifier section. The internal amplifier is a 120 Watt power amplifier capable of producing incredible bass output. The SUB120 employs an electronic crossover that adjusts the high frequency cutoff point for the subwoofer, and also, a high- pass output for your satellite speakers. You will achieve a tremendous bene- fit in sound quality by running your satellites speakers from the SUB120’s High-Pass outputs. The reason for this is that when your satellite speaker receives the filtered output from the SUB120, it will no longer be looking at the frequency below the crossover point. Let’s say your satellite speaker has a natural frequency roll-off at 70 Hz, and you are sending full range signal (as low as 20Hz) to the satellite amplifier and speaker. Even though the speaker can only reproduce 70Hz and up, the amplifier is still outputting 20-70Hz, which is wasted power and ulti- mately turns into heat. By using the SUB120’s High-Pass output, the satellite amplifier and speaker never see the frequencies lower than what’s set by the Sweep frequency. This means you’ll have more power dedicated to

Sub120 specifications

The Samson Sub120 is a compact yet powerful subwoofer designed for both professional audio applications and high-fidelity home entertainment systems. Engineered with innovative technologies and robust features, the Sub120 aims to deliver deep, impactful bass that enhances the overall listening experience.

At the heart of the Sub120 is its 12-inch low-frequency driver, specifically designed to reproduce low-end frequencies with accuracy and depth. This driver is crafted to produce a wide frequency response, typically ranging from 25 Hz to 150 Hz, allowing for a rich sound that can handle everything from thundering explosions in movies to the subtle nuances of acoustic music.

One standout feature of the Samson Sub120 is its built-in high-efficiency amplifier, which provides a peak power output of around 400 watts. This ensures that the subwoofer can fill a room with sound without distortion, even at higher volume levels. The amplifier is designed to work synergistically with the driver, optimizing performance and providing a seamless listening experience across various audio formats.

The Sub120 also incorporates adjustable crossover settings, enabling users to tailor the audio output to their specific needs. This feature allows for precise control over the frequency range, ensuring that the subwoofer integrates smoothly with other speakers in a surround sound system or home theater setup. Additionally, this flexibility helps in achieving the desired balance between bass and mid/high frequencies, ultimately enhancing the overall sound quality.

Connectivity is made easy with the Sub120, as it offers multiple input options, including XLR, TRS, and RCA connections. This versatility ensures compatibility with a wide range of audio equipment, making it suitable for both live performances and studio environments. Furthermore, the Sub120 is equipped with a Phase switch, which allows users to adjust the phase alignment with other speakers, aiding in creating a cohesive soundstage.

The design of the Sub120 is another notable aspect. It features a rugged, yet stylish cabinet that not only enhances its aesthetic appeal but also contributes to the durability of the unit. The front-firing port design helps to maximize bass response while minimizing port noise, further elevating the listening experience.

Overall, the Samson Sub120 is a remarkable subwoofer that combines advanced technology, user-friendly features, and robust build quality. Whether used in professional settings or for home audio, it is designed to deliver powerful, deep bass response that complements any audio system.
